4th up, I offer another impressive sub, One of my favorite tred and true subs, A True Bass Ultra 8 D2 with Flat Black Dust Cap and White Logo. I have used this sub for probably 8 hours so its starting to break in and loosen up. I'll take 60 Shipped Con-US
TSP's for this sub are
Re = 3.4298 ohms
Fs = 37.3410 Hz
Zmax = 46.4751 ohms
Qes = 0.3413
Qms = 4.2834
Qts = 0.3161
Le = 2.2975 mH (at 1 kHz)
Diam = 155.0000 mm ( 6.1024 in )
Sd =18869.1914 mm^2( 29.2473 in^2)
Vas = 10.5085 L ( 0.3711 ft^3)
BL = 14.3582 N/A
Mms = 87.4380 g
Cms = 207.7628 uM/N
Kms = 4813.1816 N/M
Rms = 4.7893 R mechanical
Efficiency = 0.1506 %
Sensitivity= 83.7971 dB @1W/1m
5th I offer a weird set of Pioneer 6.5" Pistons with dual spiders, rated for 50watts. New only pulled TSP's and checked that they moved properly. Neat Little things. Cant find the parameters at the moment but would be glad to pull them again if you'd like, I do remember Fs was 58Hz and Qts was .73 I believe. $20 plus shipping for the pair Con-US

6th may I entertain you with the Idea of picking up some of Caionzo's goodies that I cant find a good use for. Very capable lil drivers, very clear sound and extension to 30Hz in .5 @ 33Hz per. I fed them 200rms and they never exceeded Xmax or warmed up. The Off-White colored stuff is clay Caionzo used to seal them, they have the same frames as the Eu-700's and dont seal well without carpet or something to fill. $65 shipped for the pair Con-US
