i personally had the 801s3's with sound anchors/tip toes and a maughn box. sound anchor makes an excellent stand and mechanically grounds the speaker which tighten's up the bass.
without good stands or at least the manufacturer's supplied spikes the bass will be poorly defined and boomy. the maughn box is no longer made; krell also used to make an aftermarket bass alignment filter (fancy name for an equalizer which boosts the low bass frequencies by a few dB's). although there is an audible difference between inserting a B.A.F. between the preamp and the amplifiers (requiring extra interconnects)
it is not a necessity- that is, unless you have a large collection of pipe organ music.
older B&W 801's and 802's included a stock BAF- a small black box that usually just fit behind your rack on the floor. it didn't look like much so krell and Maughn, inc.
decided to make a more sophisticated unit (for about $1000).
the maughn box mimicked the levinson 23/27 amps-black anodized face with a red led, so it looked very nice (as did the krell). the sonic improvement over the stock filter was pretty subtle, at least with the audioquest wire i had at the time. my pitch for the 802's is that i heard a pair play a bruckner symphony- they sounded really great, with very deep and nimble bass. OTOH, bass down to 19Hz in a relatively small speaker system made the 801 fairly unique at the time, although the 12in. woofer starts and stops a bit slower. read lipnik's review of the 801 if stereophile still has it on their web site, or the 802 review in the absolute sound. they will go into more detail than i can go into here about the speakers' designs. i still get a kick out of lipnik's parting comment that the 801 was "the audio end of the road"- i.e.- at the time, one of the best speakers you could buy at any price.
