After visiting my local HiFi store yesterday, I have decided to upgrade my 3 K7 fronts with M&K 850s. I would also like to upgrade the sub. I would be willing to spend up to about £1800, as I would like to get the M&K MX350. Unfortunately, that is too big and I would also like it to have a wood finish for the WAF. The dealer suggested the MX700 (push/pull) sub? My worry with this is it still only has 8" drivers, which I already have in my VX100s. I cannot fit any of the more upmarket SVS subs, as they're too big (as I've stated in a previous post). There is the M&K VX860, which is hard to find any info on. The Velodyne SPL 1200 (or even a pair of SPL 1000s for a similar cost to the MX350). I am also considering a pair of MJ Acoustics Reference 200s. Any thoughts would be appreciated.
