Hi,

The Q15.2, as a ported design, attempts to strike a balance, as so many bookshelf speakers seem to try to do, between small size and low-frequency response. On this model, there are slight colorations in male vocals that can be easily picked out.

KEF's center channel speaker, the Q95c.2 uses the same driver in a closed box of half the volume as the Q15.2. The result is that the Q95c.s does not go as low as the Q15.2 but vocals and imaging are even better, in fact, the coloration practically disappears.

I called KEF and they admitted that the Q15.2 has that problem and also agreed that the sealed box is superior. The sealed box offers a -3db point at ~80 Hz, which is perfect in an HT application with a subwoofer.

I would use the Q95.c all around except for two issues - the cabinet shape is unappealing for anything but TV-top use and KEF, in their infinite wisdom, have chosen to price it the same as a pair of the Q15.2s.

I'd like to make custom cabinets that blend in well with my room and having made cabinets before, the mechanical aspects don't worry me. Are you suggesting that I keep the front baffle dimensions the same and just make the cabinet half the depth?

I wouldn't attempt it unless I was fairly sure that I'll see an improvement. The concentric design with its superb imaging and dispersion is what attracted me in the first place.

Regards,
Adnan
