Hmm - there's a lot of hammering in the above about the 802 S2 with feeble bass & the Bass-alignment filter being rubbish. I've had the 802 S2 for 18 yrs now & in the last 2 years, I did a lot of work related to the B&W Bass-alignment filter incl comparisons with the Krell-made one.
I've now used the same circuit topology that B&W used for their Bass-alignment filter BUT using only the finest MIL-Spec parts, incl the finest Vishay Bulk-Foil resistors and also actively buffering the filter's inputs & outputs. The power-supplies were also heavily beefed-up by a scale of 20 times and the speakers were put to test.
OMG!! what a damn transformation! Not only does it now do low bass, it does it with a class of its own while the mids & the upper bandwidth remains clean, clear & untouched.
The legendary man who passed away designing them - Late John Bowers knew himself very well what he designed indeed! In short, almost 2 decades later, these speakers have no peers - if you have the right ancillary gear for them and if the listener is a matured, sensible fella! Its not loud heart-beating speaker BUT a super smooth one spanning the freq from subwoofer terrain to the extreme upper high that their ferro-fluid counterparts in the latter series can only dream off!
Voila! The Matrix 801 & 802 - Series 2 !!
