Review on KEF Q150 Bookshelf Speakers Walnut by Chris Long

Revainrating 5 out of 5

Compared to Q Acoustics 3020i and Jamo S803s - Kef q150 is a clear winner

I bought these in white on Father's Day when they were on sale for $300. I also bought a Q Acoustics 3020i ($300) and a Jamo S803 ($200) around the same time to give them a listen and see which pair I'd like to keep. I ended up leaving Kef q150 (and Jamos). All three are very good speakers. which I think anyone would be very lucky to have. All three look very good, which is very important to me, but I think the kefs are the prettiest. The build quality is the same on all of them, I haven't had any issues with any of them. Jamos is definitely a step below the other two but they still look very sharp and I didn't care. The Q Acousitcs may have a slight advantage in body construction over the Kefs, but they're all pretty good. The Jamo S803 are great - they have a dynamic signature that boosts the highs and mid-lows a bit. This is great for apartment level listening as I can set the speaker volume to a medium level that doesn't bother my neighbors and still find the speakers interesting to listen to. I found the Q-Acoustics to be very flat - to the point where they were comparatively muffled at my preferred volume levels. Jamos don't play as deep as I had hoped - a subwoofer is a must. The Kef actually went deeper than the other two, which surprised me because the driver is smaller, aside from the massive surround sound. In any case, the Jamos add some energy to the higher bass, but fall off too quickly to at least satisfy me. Also, the Jamos are less efficient than the other two pairs - they need more power. On the other hand, I have a 20 watts RMS per channel amp that was able to push the Jamo past my comfortable listening level in a medium sized room. They're inefficient, but nothing special is required to make them work. Q Acoustic 3020i are also very good. I like rounded corners. They are bigger than they appear because these speakers are very deep. I think I like the proportions of the kefs best, but then again, all three look and sound good. The 3020i have a rather flat sound signature and are certainly a bit more refined than the Jamos. However, the image and soundstage were the same. Again, I kept the Jamos and not the Q Acoustics because I just had more fun listening to music with the Jamos than with the Q Acoustics. The 3020i is probably "better" but I personally recommend the Jamos even if they are the same price but especially since the Jamos are a bit cheaper. There are cookies. In every way imaginable. I could actually hear the difference the Uni Q (concentric) driver makes. The difference was immediately apparent - nothing sounded wrong or bad when I listened to other speakers, but everything was deeper, bigger and clearer, penetrating kefs. Also, to my surprise, these speakers are noticeably deeper than the other two. I still need a subwoofer for my own taste, but they're a lot closer to the point where you don't need one, and for many genres they would be perfect on their own. this speaker is what makes me really love them. The speakers start to fade into the background and the room only seems to be playing music when you're playing a well-recorded track with properly positioned speakers. My brother-in-law has an LS50 and they impressively come close to that experience for a fraction of the cost. The LS50 is better in every way, much like these Kefs are better than the other two pairs, but the Uni-Q driver isn't just marketing gibberish. and most of the Christmas season) the solution is simple. But at $550, it's unclear if the difference is worth the cost. It will be a personal decision. I would probably choose Jamos for the best value for money. All three pairs of speakers are very good, but the q150 was the clear winner in my comparison. Note: I tested these speakers in my living room but ended up putting a pair on my desk. However, I can't yet say how the columns will fare in the near field.
