The Uni-Q driver makes a difference

These speakers have the unique Uni-Q driver configuration with the tweeter and woofer concentrically mounted. I love how all of the sound comes from one point. The tweeter has a detailed sound but is never fatiguing. You can listen to these speakers for long periods and never become fatigued. The crossover network in this speaker is really well tuned. The crossover between the woofer and tweeter is seamless. The only thing I could wish for is a touch better bass performance. I could add a subwoofer.

KEF Q350

An egg does you no good until you crack it. I had these speakers on my stands for eight months, and although they didn't sound bad, they were consistently underwhelming, and just left me flat. Then one day I put on some Mary J Blige, which even at medium volume had those drivers at the end of their throw. Believe me the speakers let me know that. It was very uncomfortable, but I thought maybe that's what they need. I let them play until I just couldn't stand it anymore. I turned them off, and decided they had enough for today, and replaced them with my Polks which I listened to for a couple of weeks. Then I decided to put the Kefs back in, not even thinking about my little "experiment ", and not really expecting any sonic difference. But, holy s**t, I was STUNNED. I had indeed cracked the egg. The sheer size of the sound had doubled, and the sonic signature left no doubt as to EXACTLY what these speakers are supposed to sound like, which is really, really good. I won't expand on that as it could vary with signal chain. What I said about these is also true of the 150's as although it's a 2.1 system, I run four speakers in my own time tested configuration. I have a powerful amp with dual binding posts at left and right. Love these speakers now.

As usual, KEF is great!

These match our other KEF speakers perfectly. Timbre matching is important and we have a full KEF system with these as surrounds. They work really well. You can't go wrong with KEF.

Just OK

Bought due to positive reviews I saw overall and Kef's good reputation. I think they sound OK depending on the song and were able to be present in a large room relatively easily but overall I kept getting a very "box-y" impression from them in the midrange. I think they are worth a shot if you are looking for a moderately bass heavy set of shelf speakers, but not for me. Not impressed with the construction or finish although I do like the overall aesthetic. Crutchfield customer service and loyalty A1+ as always.

Great sound, issues after a short while though

I wish I could give a higher rating as these speakers do sound very nice. Unfortunately I had an issue with one woofer distorting after a few months of use and becoming unusable without severe degradation of sound. I received good customer service from KEF but they don't have a replacement woofer. I am now waiting for an indeterminate time to be able to use my nice speakers

Excellent Speakers for the Price

Recently purchased these after more than a decade on my old speakers. These were on sale for $599 and I decided to pull the trigger. I cannot speak to the technical specifics like the other reviewers; I don't have that type of knowledge or ear. What I can say is they sound amazing in the room and I'm thrilled with the purchase. Only problem now is finding the right stands, and a new stylus for my Micro Seiki. You will not go wrong with these. KEF makes amazing products. And, it goes without saying that Crutchfield's customer service was on point, as usual.

Great imaging, but very rolled off highs

Don't judge these speakers out of the box. The Q350s definitely require break in--I had to run them loud for 30 hours before they loosened up and came alive. Right out of the box, I thought I made a mistake buying them, but after breaking them in, I'm starting to appreciate them. Great imaging and soundstage. The sound is very clear and detailed. The mids sound great, and they have surprisingly good lows for the size. However, as a few other reviews have noted, the highs are noticeably rolled off / muted, which really detracts from the overall sound. High hats, cymbals, snare, tambourine, shakers, and other normally crisp instruments sound distant and weak. I find it unnatural and distracting. I've seen so many positive reviews of the Q350s that I can only assume those people have a very different preference regarding highs. One place that the Q350s excel is on bright recordings. Tracks that sound harsh on my other speakers and stereos sound fantastic on these speakers. One example is Lift Me Up (Wakanda) by Rihanna. I can crank up that song on these KEFs and Rihanna's vocals sound amazing--zero harshness, but with lots of sharpness, crispness, and detail. If I play that track on my Klipsch's or car stereo, the vocals are definitely harsh. I've ordered an EQ to see if I can coax out the highs that I'm looking for in these speakers. These definitely aren't worth full retail, but the Open Box / Scratch & Dent plus Sale discount makes them a

At first I was worried going from floor standing Monitor 7 to bookshelf speakers would be a downgrade, but frankly I haven't noticed. The KEF's spread out the sound so well in the room and are a bit more precise then the old speakers, working much better in a HT setup then the floor standers did.I got to admit, I love the KEF sound.

KEF Q350

I am 10 months in on these speakers. So, here goes-first, the positives: Build quality is good. They are a solid speaker and I have not detected any cabinet resonances. The Uni-Q driver-the dispersion and imaging that this concentric design brings to the table is wonderful. The sweet spot for these speakers is large. Because of that they are easy to place. The biggest consideration would be how close to the wall do you want to place them. They are rear ported but they do come with foam plugs for the ports. As to sound, the mids are rich and full, the lows have a surprisingly good presence exceeding what the rated frequency numbers suggest. In my experience these are forgiving speakers. The negatives: KEF should sell these with grill covers. Because you have to buy them separately that is a strike against. Some people think these are good looking speakers. I think they look like binomes from "Reboot". Well, beauty is in the eye of the beholder. Back to sound-these are "warm" sounding speakers. You might say the top end is rolled off. To my ear the highs are muffled and lacking in presence which hurts clarity and definition. (But, oddly, is what makes them a forgiving speaker.) Some advice--don't judge these right out of the box. Give them time to break in.

Great sound quality and appearance

I replaced my KEF Q150s with these Q350s. After a brief break-in period of perhaps 30 days, I noticed amazing improvements in clarity and bass delivery in my listening room with the Q350s. I am using these with 24-inch VTI stands and facing directly into the room with very little toe-in. Placement is about 3 feet from the back wall. Also, the walnut vinyl wrap looks pretty decent to my eyes. These KEF speakers provide sonic performance that I believe reflects their highly regarded and much more expensive up-line models but at a more affordable price point. Highly recommended.

KEF Q350

These speakers are great for the discounted price. I bought the open box option. Let the speakers break in for at least 100 hours. When driven with a push pull tube amp, this is about as good as speakers at this price can sound. Warm, rich mid-tones, liquid treble that is not brittle or sharp, but still has air and sparkle. The bass is good, not great. Bass is best with the port partially plugged, and it does sound lower than the spec at 63 hz. The speakers greatest feature is sound stage. They throw a deep wide center image. Stage extends beyond the speakers, very good separation and clarity. They have an excellent off axis response. when spaced 6 feet apart, 30'' from the backwall to the baffle, tow them in just a hair. Perfect !

Glad to have more of this sound in my home

After buying a pair of 150s a couple months ago, I decided I wanted more of this sound. With these 350s, those 150s, and a pair of 104/2s, I plan to build my first surround sound system (a 6.1, as unusual as that might be) On these speakers specifically, they sound exactly as I expected. Almost the same sound signature as the 150s, but the sound is just "bigger" through bigger drivers. I like bigger sound. I also like that they're not treble heavy, as too much treble hurts my ears and isn't pleasing during listening sessions, it's tiring. If you want to see how these measure across the frequency range, I'm sure that information is available. To me, they're well-balanced and musical and will make a great pairing to my old school 104/2s and their own little brothers in a surround sound setup.

Not my cup of tea.

I auditioned these hoping to downsize from my ELAC DF6.2 floorstanders, and maybe get some of the KEF magic I remember from my old 103/4s from the 1980s. It took no time to discover that these didn't have the sound character I was looking for. Granted I prefer a brighter sounding speaker than the norm, and these aren't, but the deal breaker for me was what I would describe as an almost cardboard-sounding character to both male and female vocals. I could hear some nice subtle detail in specific instruments and passages, and the bass extension was impressive for the size, but it was almost like the tweeters weren't pulling their weight. Ran them on both a 45-watt Marantz and a 70-watt Rotel, and no difference. Sent them back the next day.

Got a great deal on the KEF Q350 from Crutchfield as an open box. These are impressive speakers replacing a pair of Klipsch speakers. The speakers have superb sound with a lot of clarity. Listening to the KEF Q350s I am impressed with the soundstage that they create. Driving the speakers with a Cambridge AXR100 (thanks Crutchfield) sourcing Amazon Prime Music thru Windows 10 computer decoding thru a D10s. Recently my go to music has been Indian Healing Music (TCO) and the sound quality is surprising and refreshing. This is a super upgrade from my previous music setup even on a budget. Couldn't be happier with my purchases from Crutchfield.

KEF Q350

These speakers do allow for great spatial audio and do not need to be pointed in 1 position for a good listening experience. After about 100 hours of listening I would rate these as an excellent mid priced speaker that packs a lot of value and performance for their money. The added benefit of a non-centralized placement can be a big plus for some people depending on their space to work with. I've tried the speakers with and with out the bass port plugs and they do a great job of eliminating bounce in tight corners. The fit and finish is well executed for the price and the walnut book shelves are slightly higher scale in terms of presentation over the all black models which do have their own unique textured pattern.

One of the best sounding speakers I've ever heard, the q350 is now a prized part of my collection! I have 3 other speakers. All are great with different designs. Someone said the kefs dont sound good at low volume. Not true! So, if you would like a great stereo image, nice clarity, good but not thunderous bass, terrific mids and highs, well it's all here! I got the scratch and dent and saved even more! I like that. Enjoy the uni-q sound here! Highly recommended!!

After a few days listening to various genres of music I find the Q350's very clear and clean sounding. I currently own the Signet sl260 speakers purchased in the med 90's. I was just actually looking for a slight upgrade to replace these outstanding speakers. Very close in sound the two brands are powered by a jolida jd1501. So to be honest I didn't take a step back in sound just more close to a lateral move. The Kefs are very nice just keep them off the wall about 12".

Q350 compared with

After extended listening: 1. Polk R200 deepest bass, most extended treble, most neutral. Good power handling. 1st order woofer crossover requires ear height to be between the woofer and tweeter to prevent cancellation. Best build quality. 2. Kef Q350 prominent British midrange sounds best on some tracks. Better musical texture than Polk in bass and midrange. 3. Elac Unifi 2.0 least efficient of these low-efficiency speakers. 100 watts minimum. The least amount of bass, could use some boundary reinforcement. Sounds rolled off past 10khz, eq would help.

Surprisingly efficient speakers, not to mention great sound.

Surprising performance. I thought that, with the 87 dB sensitivity rating, I would need to upgrade my 350s when I decided to build and move to a flea tube amp from Analog Ethos. I was looking at Tekton, which have very high sensitivity, but I figured I'd build the amp and see what I thought. What I thought was "Wow!" Driving these Q350s with analog circuitry makes them sing. A musician friend of mind was just stunned by the sound - everything from Mozart to Miles to Zappa he claimed had never sounded better. So as long as you have enough input signal to the amp, six watts actually work with these bad boys, and they can get pretty loud. Quite impressive. They also sounded excellent with my legacy 70 wpc Kenwood, but the amp selection makes a BIG difference in the sound you get. So go with a quality amp and you've got yourself a nice set up. These are the kind of speakers than can give you an almost physical punch with certain types of dramatic music, if you know what I mean. Particularly orchestral stuff.

Good value when on sale

This is a warm, pleasant sounding speaker. My application has the speakers underneath a TV on top of a hutch, laying on their sides. In this configuration the bass is too aggressive with the vents open. Adding the port plugs tame the bass peak nicely. Vocals are not quite as prominent as I would like for TV listening - I need to try some equalization. I did some measurements. Response is tilted downward about 3 dB from the mid-pass to the treble. Upper mid-range is a little recessed on top of this. Distortion levels are very good below a watt, then go up quickly with volume. With the ports plugged the box tuning frequency is about 80 Hz with a Qts of 0.71. In a home theatre a setting of small with a crossover of 80 Hz would be a good starting place.

Great clarity, Soundstage and Imaging!

I purchased these KEF Q350's from Crutchfield about 6 months ago along with the Cambridge AXR100 Stereo Receiver and couldn't be happier. The Soundstage and imaging of the KEFs are wide and simply amazing. And the clarity of the speakers pair up perfectly with the warmth of the Cambridge AXR100. They sound great when playing my vinyl records - mainly rock and heavy metal. I also have them connected to my TV via optical digital cable and the clarity of voices or listening to sporting events is excellent. The perfect "all around" speakers for the price.

All around good bookshelf that can stand on its own.

The mids and highs are very good. Clear without being sibilant, accurate without being revealing. You could get away without a sub in a smaller room, and they do a good job of giving you the "feel" of bass deeper than the specs. I did end up adding a Kube 8b for a little more punch at higher levels (the small drivers have their limits). I think the sensitivity rating is a little optimistic, and the frequency range (particularly the bass) is a little pessimistic.

NORTON SHORES

I ordered these in the walnut finish and they are beautiful. As has been pointed out elsewhere they don't come with grills and so these must be ordered separately. The sound is full and rich, with great depth and detail in the lower midrange especially. Excellent spacious sound stage. Vocals (especially male) come through with clarity and detail. I think the sound suits symphonic music particularly well. The downside for me--and this is certainly a personal preference, although my son agreed with me--is they lack a little crispness and detail at the top end, where the treble is rolled off slightly. They did not have quite the right sparkle to highlight metal acoustic guitar strings or the edge of a snare drum. For that reason, I chose not to keep them but to keep looking.

This is a very stylish, modern looking speaker. They are a little boxy, but still manage to look very good. I really like the sound of the Uni-Q driver array. The sound they produce is pleasing, and the soundstage is larger than expected. I'm using these as my rear surround speakers, and now I'm more interested in whats behind me than what's coming in front of me. I think they are more on the warm side, compared to some speakers, but I really enjoy the sound and the warmth they produce. They're still breaking in since they're new, but I'm not disappointed in the sound that I'm getting right now. The base is ok but if you were using these as front speakers, you may want to add a subwoofer.
