seperate mid/high box

[greenboy]

Hey Passinwind,

Killer components in boxes that look too audiophiley! ; }

What's the internal size of the sealed cab? What are you crossing over from the woofer to the mid at? After experimenting with the 18sound 6ND410 in WinISD's filter section at 480 watts, and with various rack pieces in lieu of SMS. I've found that with a 2.5 dB/0.5 Q parametric boost at 300 Hz (crossed over at 4th-order LR at 300 Hz) that you can use it in a 2 cubic foot box and still end up with a great flat summed signal if the 3015LF is asymetrically crossed over at 350 Hz 4th LR.

Amazing that the 6ND410 is so pliable - no overexcursion there, great freedom from internal reflections, and beautiful phase/group delay melding between it and the 3015LF. Really benefit from having a good SMS like the Rane RPM or the Peavey VSX 26 : }

How are you liking the 18sound waveguide flare and the BMS ND4552 now that you've got to play for awhile?

Yeah, yeah...I never should have clear coated the first one. I'm a terrible wood worker, and it's always weird when people compliment my very obviously homemade cabs.

~360 cu in, actively LR24 crossed at 635 Hz for now. I have a really beefy 730 Hz passive crossover built up that I tried briefly too. I'm kind of working around the power amp distribution of 550+ watts to the 15 and 330watts or so to the top. That'd be PLX1804 and PLX1802, respectively.

I actually tried leaving the back cover off the mid compartment. Still sounded very good, and got plenty loud without complaining. I'll play with some of that stuff you mentioned when I build the next top box. I could get around 1.5 cu ft net with the same outline dimensions if I didn't make a separate mid driver compartment. I'm also looking at maybe porting the mid compartment though.

Jah, mon. The Rane is proving very useful indeed.

That's the goods, right there. As I told you, just listening to CDs at normal home stereo volumes is a real joy with this cab setup.
