Since they are originally a dipole custom designed woofer, why not use them for IB? I have a set of 8 as i don't use these speakers anymore (1 ribbon is not working right ) and I have a pair of SoundLab A1's now..
I tried to find the original specs on them, here's what I found:
Power capacity: 90W/180W RMS/peak Frequency response: 20 ~ 3,000 Hz Nominal impedance: 3.2 Ω Voice coil diameter: 1" Magnet weight: 20 oz. Sensitivity: 82 dB W/M Fs: 28.5 Hz Re: 3.5 Ω Qms: 4.03 Qes: 4.03 Qts: 2.0 Vas: 355 L Mms: n/a g BL: n/a Xmax: 12 mm
Using the formula vas x drivers (8) x 20 divided by 28.4 I come up with 2,000 cubic feet. I can mount these low in the front wall and behind that wall is my 4 seasons enclosed, fully insulated and windowed porch with a total CF over 3,500.
I tried to find the FAQ.. Can someone point me the right way to figure out how to do this? I haven't figured out how to power it up yet. Maybe 2 Electro Voice CPS 4.5's?
Crossover set points and DSP with my DEXQ HDP-5
FWIW: I use a vintage Bag End Infrasub 18 with my 'Labs right now and it sounds pretty good. I jus wanna either sell or use these Carver's as they are taking up a lot of storage space.
