I tried a B&W matrix HTM center channel speaker with 801 matrix series 3 front speakers and went to the HTM 800 with great results. The HTM 800 is the HTM1 black cabinet with HTM Signature drivers and crossover. A huge improvement over the original HTM. The 801s have external North Creek crossovers and are driven by a Krell FPB700cx.
The HTM 800 is driven by an FPB750Mcx monoblock. Hope this helps.
