I know this may be straying away from true DIY but I figured it'd be the best place to start... I recently came upon some of these subs in a state lot. I currently have three sets of them. I figure ill use two in my ht and keep one for parts. The unit itself is 3 x 12" in a vented trapezoidal box. The cabinet itself is 1/2" baltic birch "extensively braced" and the literature that i've seen on it says that each driver is in a separate vented sub-enclosure. The specs for the system (most of these numbers are gibberish to me) are as follows:
Freq. Resp (1W @ 1m): +- 3db 50hz to 1.6kHz, -10 db 40 Hz
Axial sensitivity (db spl, 1 watt @ 1 m): LF 100
Impedance: LF 3 x 8 ohms
Power handling, AES Standard: LF 1500 w
Calculated Max output (db spl): LF peak - 137.8, LF long term - 131.8
Nominal coverage angle/ -6dbs: Horiz 160*, Vert 60*
Recommended high pass: 24 db/octave 40hz
The dimensions of the unit are 40" tall, 21" deep, 24" wide frontside 12 3/4 wide in back.
I'm trying to find a way to integrate this into my HT, I'm thinking if I buy an iNUke 12000dsp I could power two of these. My concern is that the output really starts to roll of at 50Hz. Am i wrong or is this awfully high for a sub? Am i just expecting too much out of three 12's? Should i find a way to seal the box? Should i gut all three and make one big frankenstein sub? I really don't know what i'm doing but feel like it would be a huge waste to not at least try to do something bada** with them. Also the guy i got them from insisted that they have been tested and "work".
Thanks in advance
