Hello,
Bought a subwoofer made for a local recording studio that they weren't satisfied. Used a (really impressive looking) P-Audio TM-12 subwoofer driver, and 2 Peerless 12"XLS radiators in a well made 60L enclosure. Going to recycle the amplifier, but will use my own subwoofer drivers, and so selling the active and passive drivers. P-Audio subwoofer is for local pickup only in Los Angeles or thereabouts - it's really big and heavy. Passive radiators can indeed be shipped!
P-Audio TM-12
This driver is reminiscent of the very impressive JBL W12 GTI - has a dual gap motor, inside/outside voice-coil, mirrored spiders - a very substantial powertrain, all in all. Very low inductance and strong motor (like the JBL).
Fs 48.5 Hz.

PRs sold, Alpine available!
Passive radiators sold, and I'm putting up two really nice Alpine 4 ohm subwoofers for sale. I was going to use these at home in low Q sealed boxes but then found 8 ohm subwoofers which worked much better for the amplifier I have.
Each for $105, or both for $195, firm + shipping. These are really good subwoofers, very well engineered with a flat BL curve and a clean 20mm xmax that model really well in a small sealed box: Qts = 0.7 in a 28.5l box, and Qts = 0.6 in a 57 liter box!
Factory specs for Alpine:
Alpine Electronics of America, Inc.
T/S for the Alpine SWR-1223D (from my Unibox modeling):
Alpine SWR-1223D

P-Audio TM12 price drop
Hello,
Latest prices:
P-Audio TM12 dropped to $95. This is definitely local pickup only - driver is a beast - weighs 34 lbs.
MiniDSP 4x10HD = $315 + shipping, firm.
Tannoy IWSA500 standalone subwoofer amplifier
500W @ 4 ohms, BASH power supply
$215 firm + shipping
http://hifiheaven.net/store/Tannoy-i...ofer-Amplifier
Keiga 52100 subwoofer plate amplifier
1000W @ 4 ohms, high efficiency (86%) switching output stage
http://www.keiga.com.tw/products_kgnd52100.html/
$305 firm + shipping
NHT A1 mono amplifier (usually used with subwoofers, but is well engineered full-range sub)
RCA and balanced XLR inputs
signal sensing/12V trigger
class H so much higher efficiency/lower power draw than single rail Class AB
very slim
no controls whatsoever (NADA!) so make sure you're using with active crossover/home theater receiver, as it has no filters, low-pass, gain, anything whatsoever!
Quite scratched but functionally perfect
300W/200W RMS @ 4/8 ohms
$95 + shipping
Exodus Audio Tempest-X (not the X2) 15" subwoofer with XBL^2: $145
Exodus Audio PR18 18" passive radiator, cast frame, with mass kit: $75
Pretty nice looking oak-style cubic box with one 18" cutout (was going to mount the subwoofer opposite the PR): $40
$215 for the above three components. Very much local only - the Tempest-X is the heaviest driver I've handled.
Cheers,
Tal
