Did you talk about the center before? I don't recognize it and can tell it ain't diy. Do tell. BTW, nice score on the Phil 3s. It would take a killer center to out do their phantom center capabilities. I got that demonstration at YAA's.
I wired up a couple of small monoblocks (MA500) up to that RBH dual 10" ported sub in order to free up one larger monoblock (MA700) which when paired up with its twin can power the mains (Kurt's STs).
Speakering is a lot of work.
I think I've casually mentioned it, but am waiting til I can get full CTA 2034 data on it - use that to revise the electronic crossover as much as possible, but also post its actual performance rather than, "IT SOUNDS AMAZING!!!!!!!!!!"
I did a similar construction technique to that of Gene's Status 8T's. But I revised the edges for my purposes, and then coated the whole structure in a resin I created to increasing damping despite two of the edges being rather thin. (the bright blue went navy once dry)
Scanspeak drivers are dual 7" 18W/8531, 4" midrange 12MU/4731, and of course, the 6640 Beryllium tweeter.
Crossover is a mDSP 2x8 board. Dayton MA1260 gives them powah. I didn't actually complete the resin coating on the backside. I just plugged it in with an iPod in the garage and was blown away - it actually WORKS!?!?!?
Put it in place in the HT, and it's been singing right along with the Phil 3's - I purposefully designed the crossover to try to replicate the Phil 3's timbre, despite the Beryllium not having quite as much off axis potential as the RAAL 70-10. (which is also a claim I intend to prove thru CTA 2034)
Painting the house and rescuing a pup is consuming my time right now as well as a nephew to visit next month, I should be able to have a whole presentation on where I started, where I tweaked, and where I ended up.
I never got to hear the song towers, but Kurt described them as being quite capable next to the Phil 3, just the bass is the significant difference - but that too is my issue, would rather large wall mounted monitors to free up the floor space. So in proving this center channel, transferring that knowledge to front L+R, should be non problem! Didn't realize you scored an RBH 1010, tho! That's awesome!
