FS: 2x Lambda Acoustics TD15M 15" High Efficiency drivers

Not open for further replies.
I listed these a while ago along with some horns, but those sold and I figure I'd relist these separate:

A pair of Lambda Acoustics TD15M drivers. The Lambda drivers feature a faraday ring to lower inductance and improve the high frequency response of the drivers, the TD15M's with thier accordian surrounds can be used with much higher crossovers than most 15's and have a very clear midrange (200-2000hz). Normally used with 500-1500hz crossovers. I've seen 2k but that's pushing it.

They would be suitable for sealed, ported, Karlson, or even 80-100hz front horns.

They feature massive cast baskets, and impeccable craftsmanship throughout. Also they use an aluminum pole piece instead of a dust cover. The Lambda drivers were very highly regarded (before Nick closed up shop). I'd put them up against even the nicest vintage altec's or modern JBL's.

This pair is unused. I hooked them up once after delivery just to make sure they made sound. They are of course in perfect condition.

T/S parameters:

Fs 30.5 Hz
Qms 4.47
Qes 0.29
Qts 0.27
Vas 405 Liters
Cms 0.4 mm/N
Mms 70 grams
Sd 855 cm2
Rms 3.0 Kg/S
Bl 27.6 T/m
Re 6.6 ohms
Z 8 ohms
Le 0.2 mH (note the super low inductance due to the faraday)
1WSpl 98.1 dB
Xmax (linear) 3mm
Xmax (mech) 10mm

They're extremely linear in the 3mm range, and generally they are fine at a 7mm design max in the bass range.

Asking 450 USD + ship, two 16.5" x 16.5" x 14" @ 28lb ea boxes, the original shipping containers, from 54603 zipcode.
