      Hey guys,

      Had the pleasure of hearing the Uni-Fi B5 at AXPONA in Chicago — very impressive!

      I’m wondering though, given their relative inefficiency (which is totally fine… I’m good with that), what kind of power would be a good starting point? At the show, the electronics were spectacular, but in the reality of my own life, well, that ain’t happenin’. 🙂

      Currently, would my modest Marantz NR-1506 (with 50 watts per channel at 0.09% THD) be suitable? Or should they really have more ooomph than that? My room size is pretty typical at about 14′ x 16′, I think.

      Hi,

      50 Watts should be enough to get the UB5 speakers sounding pretty good, however you need to make sure that the amplifier you are using is designed to power 4 ohm speakers. The Marantz piece you have unfortunately only supports 6 and 8 ohm speakers. Your marantz unit does have pre-outs for the main channel so you can add a separate amplifier to your system.

      Thanks,

        Hi Chris,

        Regarding the receivers designed to power the Uni-Fi FB5 speakers (4 ohms), can you recommend some actual receiver models. I’m looking for the best value receivers, under $500, if possible. When I search websites at Onkyo, Yamaha, etc.., I only see receiver specs stating 6 or 8 ohms for every one, but I’m not even sure if I’m looking at it correctly.

        Thanks

        Hi if you check Yamaha amplifiers can power 4 omh speakers, they can even power 2 omh. Here is the link for their A-S500 which gives you up to 180 watts into 4 omhs. And is $ 450 USD

        Yep… this is exactly what concerns me. If 4-ohm speakers run at a relatively inefficient 85dB/watt, then you’re gonna need some pretty serious (and clean) power. I would think 100 watts per channel (at 0.08% THD or better) would be a good starting point, so that would most likely be a $500 price point on most receivers to get those specs.

        So I don’t know… is a 1-to-1 ratio of speaker cost to electronics cost a little steep? Or am I looking at it the wrong way?

      Chris,

      Hi. I am also seriously considering the ELAC Uni-Fi B5 with the center channel. I know you recommend a 4 ohm apm and I also have a Marantz but a 5008 7channel. It delivers 100 watts per channel at 8 ohms (.08%) or 140 watts at 6 ohms (.07%). So I have 2 questions:

      will that be enough for the B5? and I am not suing the last 2 channels ..can I use that as a method to bi-amp the speakers for better sound?..I mean..will that help?

      Many thanks,

      Luis

      Chris,
      I just purchased the ELAC UNI UB5 and I’ve been playing them with the a Marantz 1604. Although the specs for the 1604 indicated that they only go to 6 ohm, the sound is fine (I have a REL 7i covering the low frequency). Because I was concerned about the inefficiency of the UNI UB5 I did just purchase a dedicated amp (Parasound 275 v.2), which is rated down to 2 ohms but the specs say its maximum watts is 150 at 4 ohms. It seems like a good match spec wise, but I haven’t had a chance to hook them up yet. I will do a pre-out from the 1604 to the 275 V.2.

      My question is about the UNI UB5 maximum power rating at 140 watts. Should I worry about the 10 watt difference of 275 v.2 over the UNI UB5?

      I’m in the same boat. I need help choosing a proper av/ receiver or amp. I’m in the market for the Uni-Fi B5 and was thinking about pairing it with an Emotiva TA-100

      here are the specs:
      Analog Performance (to speaker outputs; both channels driven)
      50 watts RMS per channel (20 Hz – 20 kHz; THD < 0.02%; into 8 Ohms).
      90 watts RMS per channel (1 kHz; THD < 1%; into 4 Ohms).
      Power bandwidth: 20 Hz to 20 kHz + 0 dB / – 0.25 dB (at rated power; into 8 Ohms).
      Broadband frequency response: 20 Hz to 80 kHz + 0 dB / – 3 dB.
      THD+noise: < 0.05% (A-weighted).
      S/N ratio: > 100 dB (A-weighted; ref full power).
      S/N ratio: > 85 dB (A-weighted; ref 1 watt).

      would this be suitable to power the speakers?

        Hi RAM,

        Sorry for the late reply.

        The Emotiva amp will drive the Uni-Fi speakers just fine. We power them with our integrated amplifier which is rated at 80 watts at 4 ohms without any problem…

        Hi Tony,

        The Yamaha will power the Uni-Fi speakers, however you will be limited by how loud you can turn it up. Yamaha usually has a setting in the menu system for setting the impedance of the speakers that are connected. Now, if you plan on connecting a subwoofer and letting the receiver set a high pass filter for the main speakers you will be able to get a good amount of volume out of the unit.

        Hope that helps. If you have any further questions feel free to call us at 714-252-8843. You can talk directly with Andrew if you wish.

      Planning to buy 2 Uni-fi UF5 front speakers, 2 Uni-fi UF5 side surround speakers and 2 Uni-fi UB5 back surround speakers with a Uni-fi UC5 center speaker for a room 22.5 feet x 19 feet and 11 foot high. Planning on two SQ12 subwoofers. Do you think its the right setup or too much or too little?

      Also, planning on buying Yamaha RX-A2060BL 9.2 AV receiver. Will it be enough for the speakers? Concerned about the 4 ohm aspect of the speakers.

      Hello,

      I recently purchased a UC5, I’m planning to upgrade all my speakers to the UNI-FI series but I needed to start with the center channel because my old Polk was just crappy.

      Just as a side note, I compared the Elac to the Klipsch rc-62 and rc-52 and even though the 62 was louder and had more bass, it’s not what I am looking for on a center channel. Comparing all 3 of them the Elac was my favorite and was clearer.

      I’m running this on a Denon x1300w it seems to be handling the speaker just fine and it plays pretty loud. I can’t comment on playing with a full set of uni-fi. I would suggest getting something like a x4300h

      Planning to buy 2 Uni-fi UF5 front speakers, 2 Uni-fi UF5 side surround speakers and 2 Uni-fi UB5 back surround speakers with a Uni-fi UC5 center speaker for a room 22.5 feet x 19 feet and 11 foot high.

      Thank you very much.

      That might be overkill with the sides. Maybe try getting some overhead speakers? or atmos speakers instead? I don’t know about up-firing because your ceiling is pretty high (You should do some testing). But You have other options instead of going with 4 UF5

      I have 2 UF5s, 2UB5s and a UC5, all 4 Ohms, along with an S10EQ.

      I am considering these amps. Which would serve me best? I don’t understand all these numbers but none of them say 4 Ohms.

      I have a similar question as mikewolf1127 except I have purchased the Denon AVR-X4300H and looking for speakers. I started looking at the Elac Debut line which seems to run at 6 Ohms (which is why I purchased the x4300) but the more I read it seems the Uni-fy speakers appear to be a little better in filling a large HT room. Now I am confused on if purchasing the Uni-fy speaker solution (4 ohms) will compliment the Denon x4300 or if I need to go back to the Debut line (6 ohms). I want to setup a 5.1.4 listening environment primarily for watching movies. Unfortunately, there are no dealers around my area to even ask about these speakers…most want me to look at B&W and KEF speakers.

      Denon AVR-X4300H
      Power Output (8 ohm, 20 Hz – 20 kHz, 0.08% 2ch Drive)
      125W (8 ohm, 20 Hz – 20 kHz, 0.05% 2ch Drive)
      165W (6 ohm, 1 kHz, 0.7% 2ch Drive)
      235W (6 ohm, 1 kHz, 10% 1ch Drive)

      Note…Denon says the AVR-x4300h will support 4 ohms speakers…but I just don’t know how well….or how hot.

      Any help would be appreciated.

        I purchased a Denon AVR-X4300H two weeks ago. I’m using it to run a 7.1.2 configuration of 2x Uni-Fi UF5, 1x UC5, 2x Debut A4, 1x Debut S12EQ, and 4x Polk Audio OWM3 surrounds. I will replace the Polk with the Elac debut or uni-fi in ceiling once they ship. I also plan to add 2 more in ceiling Atmos modules (via an external 2 channel amp, as required for this AVR) for a total of 7.1.4 once Elac ships those as well. I have my crossovers on all the Uni-Fi speakers set to 80hz and I have configured the AVR for 4ohm operational mode.

        So how does it sound? Nothing short of EXCEPTIONAL! I have not heard anything even close to these for less than 2x the price. The AVR has NO problems driving these to sound levels which force my wife out of the room. I can barely stand to be in the room at reference 0db and the AVR will go even louder. AVR does not run hot nor does is seem to be lacking in any power or THD capacity. The “energy use” meter on the AVR also indicates it is not struggling in any way.

        Note that all this hinges on you having a sub and set your crossovers to no less than 80hz. If you try to drive the low frequencies though the Uni-Fi’s, your AVR is going to be under a much greater strain.

        In short, the Denon AVR-x4300H is an exceptional AVR for this system.

      I am considering buying the Uni-Fi FB5 speakers and like above have questions about compatability. I don’t see my answer so here it is:

      I have a vintage receiver and want to ensure that these would work given the ohm.

      SANSUI G7500
      Tuning range: FM, MW
      Power output: 90 watts per channel into 8Ω (stereo)
      Frequency response: 5Hz to 50kHz
      Total harmonic distortion: 0.025%
      Damping factor: 50
      Input sensitivity: 6mV (mic), 2.5mV (MM), 150mV (DIN), 150mV (line)
      Signal to noise ratio: 78dB (MM), 95dB (line)
      Channel separation: 60dB (MM), 65dB (line)
      Output: 150mV (line), 43mV (DIN)
      Speaker load impedance: 8Ω (minimum)

      Would this combination work even though the recommended specifications state an 8ohm minimum? What are the risks in using a speaker like the ELAC with different ohm capability. Appreciate input and turnaround in response.

        They will work and it is unlikely you could damage the speakers. However, you could possible damage the receiver if you turn the volume up to loud. The amp in this receiver won’t be able to deliver the power the speakers are asking for at higher volume. You risk the unit overheating and frying, or just sounding bad. Modern receivers have protective circuitry which will turn off the app if it gets too hot or overloaded. Don’t know if your receiver has that.

      I have the same question. I would like to purchase the Elac Uni-fi set, but need advice on the receiver. Ultimately, I don’t just go out and buy a receiver. I make sure I have a list of working receivers, and when a receiver on the list goes on sale, I’ll buy that one. I am patient and don’t mind waiting 3 or 4+ months. One thing I have found in a receiver that is said to be awesome is the Audyssey MultEQ XT32. I have been convinced that if a receiver is worth getting, it should really come with the XT32.

      There are so many receivers that CAN work with these speakers that I guess the big question is, what receiver under $1500 that comes with the XT32 will NOT be able to power these 4 ohm speakers?

      Also – I don’t really care if the speakers are loud. I care more about voice quality and hearing a pin drop.

      The cheapest xt32 I found is the AVR-X3300W. If I purchased this when it goes on sale, would this system suffice?

      Fry’s typically has receiver sales more than other places. Does anyone know of a way to get the Fry’s deals if you don’t live nearby?

      Lastly, I plan on having a large 150″ projector screen to get a 36 degree FOV. The speakers would have to be placed behind an acoustically transparent screen. Is this something that would sacrifice sound quality or is it just volume I would sacrifice?

      PS: I have a small to medium sized room

        I have not used the Dynaco St 70 myself. I’m not sure what modifications or upgrade have been done to improve your unit.

        My first concern is the amps 4ohm compatibility. May brief Google search said “yes”, but I’m not certain. 35 watts at 8ohms and maybe more at 4ohms may be on the lighter side of our recommended specs.

        In general, though I don’t have any information on this combination. If you try the combination out, I’d love to hear your feedback.

        After Speaking with Andrew,

        The impedance doesn’t matter, with tube amps. So at 35 watts per channel, it is a little on the low – end.

        It may sound okay, but you may lose some dynamics.

      Hello:

      Looking at the UB5 speakers and considering the new NAD C338. Specs are here:

      C 338

      50Wx2 continuous into 8 or 4 ohm. THD < 0.03%

      Thoughts on whether the C338 is a sufficient amp for these speakers would be appreciated!

      Next step up is the NAD C368, but I like the compact size and chromecast capability of the C338.

      Thinking of getting the UNifi UB5 and drive it with the Sony TA-A1ES integrated amp – it’s a class A amp. The amp is rated 80wpc and is capable of driving 4-16ohm speakers.

      On paper the Sony seems to ‘mactch’ well with the the UB5’s spec but a bit unsure of the match in reality and if the amp would have sufficient headroom if I need to crank up the volume.

      Have it currently paired to the Tannoy Mercury V4 and I find I need t crank up the volume to > 50% to get to moderate listening levels and the Tannoy is a fairly sensitive speaker at 91dB. The UB5s are lower on sensitivity and 4ohm rated, making it harder to drive on both counts.

      Any suggestions/ views on the compatibility and resulting sound signature? Thanks

      Power output
      RMS 8 Ohms / 4 Ohms (40 Hz – 20 kHz) …………. 40 / 55 W
      DIN 8 Ohms / 4 Ohms ………………………… 45 / 60 W

      IHF dynamic power
      8 Ohms / 4 Ohms ……………………………. 55 / 80 W
      THD at 8 Ohms RMS rated output ………………….. 0.01%

      which speaker will be most optimize for my Amp…

        Hello Kenneth,

        The receiver/amp meets the minimum recommended power for either speaker.

        Most people go with the B6 because of more dynamic range and higher sensitivity, for not the much more than the B5. I like the size of the B5 and in my opinion you’re not compromising much in general sound quality.

        Thanks,

      Hi Elac!

      Just filled up my 15′ x 20′ listening room with an all-Elac Uni Fi 5.1 speaker setup. At the moment I have my AVR, a Marantz SR5011, powering everything but I’m looking buy a power amp for dedicated power for my front L/R UF5s both for movies and more importantly for pure two channel listening with my turntable.

      I am stuck on two choices

      1. Marantz MM 7025; 140W (20Hz-20kHz, 0.08%) S/N Ratio 105dB; 8Hz-100kHz
      2. Emotiva BasX A-300; 300 watts RMS per channel; 1 kHz; THD < 1%; into 4 Ohms

      The A300 is half the price and has specs for 4 ohm loads on the mfg website, but I’ve scoured the internet and I’m still unsure if the Marantz is rated to power my 4 ohm speakers.

      Is the Emotiva a slam dunk decision or am I missing something about the Marantz that is a better proposition for my needs?

        Hi mofo

        From my experience, more power is always better when it comes to the UB5. The marantz aint no slouch either. I dont think you can go wrong with either but id probably drop my cash on the emotiva just for price vs performance.

        Cheers

        Hello Mofo/Ajitmoses,

        All speakers benefit from more power, not just the our Uni-Fi speakers. =)

        It’s difficult for me to choose one brand/model over another, especially since I have very little experience with these amps. Power wise 140 watts is plenty and 300 watts is plenty more.

      Hi…as per my understanding you need to make sure that the amplifier you are using is designed to power 4 ohm speakers. The Marantz piece you have unfortunately only supports 6 and 8 ohm speakers. Your marantz unit does have pre-outs for the main channel.

      Can I use Adcom’s GFA-555ii for the UB5’s?

        Hello Prandelcious,

        Based on a quick google search, there isn’t any reason you can’t. Based on power it should be more than adequate.

      Hello, I am searching for the perfect av reciever or amplifier for a set of: 2 UF5 floorstanding speakers, 2 UB5 bookshelf speakers, 1 UFC centre speaker and 1 S12EQ subwoofer. Can somebody recommend anything? if possible I would also like a recommendation for a dedicated stereo amp or adedicated amp for the UF5.

      Thank you really much!

      Hi, I was wondering if the Denon pma-60 could drive the ELAC Uni-Fi UB5??

        Hello George,

        Based on specification, that integrated amp seems light on power, so you may lose some dynamics. It will work, but I cannot say it will sound great. We recommend 40 watts per channel or more. That being said that in a near field setup or desktop setup it may sound great.

      I Own Debute F5 C5 with a Velodyne Impact 12 MK2 Sub and wharfadale surrounds pared with a Yamaha RXV483 AMP. Went with the amp after i went through the review from Cnet Steve Guttenberg. But now i am feeling that either i have not set it up properly or do i need a bigger amp. Speakers sound a bit laid back and not as exciting.
      Crossover is set at 80htz and speakers are set as small. Is there a specific setting that need to change or do i need more powerful amp?
      Rated output for the amp is 2 channels driven is at 8ohms — 80W.

      Hi guys,
      I am planning to set up a home surround sound, 99% TV/Netflix;
      2 Uni-fi UF5, 2 Uni-fi UB5, with a Uni-fi UC5.
      What requirements should I look in the receiver?
      Does Elac have one that works well for this set?
      Why this series doesn’t have the Subwoffer? What Elac subwoofer will work best with this set?
      Thanks in advance

      Hello Folks,

      So glad I came across this post. I will be moving soon, part of my plan for the new home is to add a beefy amp to my surround sound music room, five channels to be exact. My current speaker compliment consist of four Uni-Fi UB5s and a Uni-Fi UC5 (plus an SVS SB2000 Sub). I am currently driving the five ELACs with a Yamaha RX-A3020 Receiver, it does not “officially” support 4ohms per the specs. All in all it performs well, but it is lacking in presence and punch. My original plan is to get the best amp I can afford. I am targeting the Monoprice Monolith 5X200, https://www.monoprice.com/product?p_id=15593 which is rated for 300W @ 4ohms, using the Yamaha as a pre-amp/processor. Am I nuts (go ahead, hit me in the gut, I can take it) or am I on a good track? Thanks

        Hello Envelope,

        I was hoping someone could weigh in with personal experience. I know that there a few review available for that amplifier and it’s a well respected amplifier.

        As far as overkill… 200w @ 8 ohm and 300w @ 4ohm may be a little overkill, the Uni-Fi like most speakers do well with more power. We’ve tried the Uni-Fis with other amplifiers with similar power and had a great experience.

        There are usually concerns that too much power can blow the speakers, but in my experience most people will not play music/movies loud enough to max the amplifier. I find that blown speakers usually occur by accident when switching inputs or not knowing hold loud the volume knob is set. Or if a person is trying to fill a large area with sound like outdoors or a large event hall.

      Denon 3400H – I’m getting debates that it has enough power. Specs say yes, but others say no, add an extra amp like some of the ones listed above (emotiva, NAD etc…). The sound is pretty good, but how much better will it be with additional separate power?

      Hi,

      I recently purchased a pair of the Uni-fi B5s and plan to initially drive them on my vintage Yamaha CR1020 receiver which is spec’d to run 4ohm speakers. Do you know if the receiver has adequate power to effectively drive these speakers or is the CR1020 to under powered to get satisfactory performance from these speakers?

      I definitely plan to buy a contemporary integrated amplifier that will more appropriately have the proper power output to drive these speakers in the future but for now, I’m concerned that what I have at the moment is insufficient to really enjoy these speakers.

      btw, I do own a pair of B6s which I am enjoying very much that are connected to my old Harman Kardon twin powered 630 receiver. Kudos to Elac for delivering such fine speakers that are not priced for the uber high end.

      Thank you, Spencer Hayashi

      Hello Elac

      I have a Uni Fi FS U5 Slim and my question is which is better for these boxes: Marantz pm6006 vs pm8006; Is there any difference between amps. What would you recommend?

      Thanks

      Can I pair the UB5 with 2x ICEPOWER 125ASX2 BTL modules:

      http://www.sound-power.ru/files/doc/ICEpower125ASX2_datasheet.pdf

      It’s a 450W into 4-ohm short term and 75W into 4 ohms continuous unlimited (0.1% THD)

      ???

      Thanks

      Is the elac integrated amp powerful enough to get the uf-5s to their full potential, or do you recommend something more powerful?
