Bought for my daughter's surround system. Matched up perfectly with the fronts: Q700's - AND THE SOUND IS GREAT. They are excellent as rear surrounds and have very good spacial qualities as you might expect from the shape. Basic black but beautiful quality finish. Super heavy magnets might make it hard to mount in a ceiling but worth doing if done right. Easy squeazy as wall mounts due to flush (metal bracketed) cutouts for screw heads in the back. They will sit flat against the wall when completed, but know where you are going to run the wires because wall setup won't lay perfectly flat if the speaker wire is fat and doesn't go INTO the wall behind them. No biggy - just use some cheapo cushion feet to raise it out slightly if need be. Great (half of list!) price, so made it a truly worthwhile Christmas gift. Quality never goes out of style, and KEF makes some nice products at the mid and higher end of their line. The Q series do sound excellent and that's what counts.
I am using these speakers for surround sound on the sides of my room. I have only had them for a few weeks, but so far I am very impressed with the quality of the speakers and the sound they produce. These speakers have performed flawlessly so far, and the sound they produce is crystal clear and amazing. I am very happy with my first but not the last purchase of KEF speakers.
Sound very good, intended dipole effect is present and creates a nice rear sound that isn't easily located. A bit of internet research showed that these are very similar to the R800ds, except for the driver, with identical weight and dimensions but these are $1k cheaper. In fact, the current picture of the white version of this product is actually an R800ds with the ribbed magnesium/aluminum drivers. This product does not actually have the ribbed drivers like the R series or LS50.Given that they are intended to be used off-axis, I didn't feel it was worth the extra money for the improved cones. I bought these from Amazon on special, so they were almost $1300 cheaper than the R800's MSRP.
However, other internet research said that these speakers are identical and are not shipped as matched left right pairs. I confirmed this was true of my set as well. Although the two internal drivers are identical (I verified this), only one driver is used for <300Hz bass, and then it switches to dipole mode above that frequency. However, since the speakers are identical, when mounted left and right, one will "face" forward and the other will "face" backward. You can simply flip one upside down, but then the wall mounting bracket and logo are upside down. The "best" solution is to disassemble one of the speakers and swap the driver connections (four wires total per speaker) so that the speakers are mirror images rather than identical. This is what I did, and I am very satisfied. However, I did not try them before the modification and so I can't really say if it was an improvement or not. However, the theory is sound to me, i.e. with standard speakers, polarity is considered correct when the left and right cones move in the same direction at the same time, whereas with these speakers as delivered the left front and right rear will move in unison (as will the right front and left rear). With the modification, the left/right front speakers move in the same direction at the same time, as do the rears. This makes more sense to me.
Quality is great. Due to the discount available I wasn't able to get my preferred color, but it wasn't worth an extra $300. The drivers are presumably the same as all the Q series 5.25" drivers and are very beefy. The crossover looked beefy as well. They are quite heavy at about 16lbs each, as you might expect for a speaker in the this price range. Due to the weight though, you'll need a proper mounting arrangement, if wall-mounting. There isn't any relief in the mounting post bracket for the speaker wire, so I followed a previous reviewer's idea and used some stick-on rubber feet on the bottom corners and extended the mounting screws slightly to space the speaker off the wall enough that wire could extend below without pinching it at the bottom edge.
