  1. We have been tuning it for 5 years 😅 We spent a lot of time on it last year. There are a few all pass filters needed to align out of band phase and we now use FIR filters from about 500hz up.

  2. Had a rather big break-through today with the aid of friend, who helped optimize the MW's. Actually, he deserves sole credit for totally rearranging the delay and other aspects via the Xilica unit in the wake of honing in on an 80Hz (still 42dB/octave Linkwitz-Riley) cross-over that we settled on. The high-pass of the MW's remains unchanged. Also, the MW's remain hooked-up in true stereo mode. He had "fallen in love," as he put it, with the MW's for their "clean, fast, non-signature, hard-hitting bass" that "wholly integrates with the mains" (he uses a pair of Electro Voice TL880D cinema subs in his own setup). He has extensive experience with and knowledge of horn subs, and found the MW's the best horn subs he'd yet heard. Not too shabby..

  3. Sorry for the late reply as well, and thanks for getting back to me, @lilmike. I see clearly were you're coming from with your HPF recommendation for the MicroWreckers. My 8th order BW HPF for the MW's was perhaps somewhat exaggerated, not least in light of my not all that commanding use of them, so today I've dialed it back to a 4th order Butterworth HPF. I believe it actually sounds better this way, but I won't bother any of you with details to describe it. The most I've seen those B&C units move was with a recent Blu-ray showing of Blade Runner 2049 where they "jumped" 2 mm's perhaps during the scene where K's being downed in his hovercraft from a strike of lightning - and that was running the system volume 6dB's hot.. Yes, that's all they move with my typical use, but the SPL could most definitely be felt! The first weeks of use (actually until rather recently) the MW's sounded somewhat lean and lacked impact, but slowly and steadily they're really getting around to it, though I suspect running them in properly will take months. Those rugged cloth surrounds of the B&C 15TBX100'a are quite stiff, and the little they are being worked out from the limited in-use excursion won't see rapid burn-in progress. As is, after finally finding their proper on-the-side-lying placement along each side wall, I'm really pleased with the result; the MW's provide a totally effortless, uninhibited, smooth and enveloping bass that blends in extremely well with my all-horn mains - indeed they seem like a perfect match. I'm surprised they're so informative as they are. The bass is so present, clear and even liquid in a way that makes it extremely easy to follow bass-lines, and they refuse to "solidify" the way I felt the SVS SB16-Ultra did; this is bass that energizes the air, shakes it even, and is more of an enveloping, floating kind. What follows now is a rather lengthy process of fine tuning delay, PEQ, crossover frequency and slope, and subtle changes in placement (from a general outset that won't change). Right now I cross over to the mains at 91Hz 42dB/octave Linkwitz-Riley, and as mentioned above 4th order HPF Butterworth on the MW's. Great design, @lilmike - kudos
