We should have a SPL contest with NEW woofers that cost under $70 bucks shipped, it'll be awesome.

that would be pretty cool....that would be 3 pup 12's //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif but I'm sure the pups wouldn't be allowed in the contest....due to unfair advantage

I hope they go BOOM LIKE SO!

I ordered a cuspid wo-1008 made offer of 48.xx after shipping total was $80 even. Will pull tsp's and do some power handling tests, excursion tests, blah blah lol. Ordered 5 minutes ago estimated arrival between 16th and 23rd. Ill keep you updated.

Audio_Phill FTMFW. Very curious about these.

TSP's folks, sub arrived today. Not shabby at all, low Xmax, prob 15mm one way linear, but overall its a dang nice woofer for the price. Single 4ohm coil, highest BL I've tested on a single coil driver.

Here's TSP's (Pre-Break-In) for those waiting, I haven't played with power handling yet but I will, and when I do I'll update asap!

Re = 4.2251 ohms

Fs = 45.5401 Hz

Zmax = 81.6094 ohms

Qes = 0.4541

Qms = 8.3170

Qts = 0.4306

Le = 3.2476 mH (at 1 kHz)

Diam = 210.8200 mm ( 8.3000 in )

Sd = .035m^2 ( 54.1061 in^2)

Vas = 10.4992 L ( 0.3708 ft^3)

BL = 23.1539 N/A

Mms = 201.3674 g

Cms = 60.6545 uM/N

Kms = 16486.8184 N/M

Rms = 6.9278 R mechanical

Efficiency = 0.2052 %

Sensitivity= 85.1394 dB @1W/1m

1.4net @ 33Hz for an f3 (anechoic) of 29.5Hz, only needs 27sq" port area for a vent mach of .04, 36sq" for .03 (idea) max output plotted to be 113.21dB (pre cabin gain) @ 34Hz on 600 rms so expect a ~133dB in car in my recommended enclosure. Still have yet to test power handling, will get to it asap. Stay tuned, this is going in my scion TC on 500rms in my recommended enclosure, if it does good I'll up power to 1600 for some fun.

After some power testing using 25Hz sine-wave free-air it's thermal limits are definitely its short fall, I have 1K @ .08%THD to give it, and @ 1" P-P it begins to heat up, nothing bad, prob no more than 140 degrees F, Xmax is looking more like +/- 13mm. There are gaps around all the columns, (8 x 4 stack 2.5" x .5" thick so 2" total height of magnets) and plenty of under spider venting but no air movement around the coil to keep it cool. Coil turned out to be 3", I told someone 2.5" but after a bit of rigorous measuring it is in fact 3" lol. Coil is short enough so that it cant reach the back-plate so no bottoming out issue, thick windings, looks to be 8 layer but the wire is very small gauge, 24awg maybe smaller so that is the subs limiting factor. Tinsels are small gauge and woven through the spider so thats a lil bit of a bummer as well. Motor has serious potential for fun high BL custom drivers but its glued and screwed like crazy. Thats where I stand now and I'll keep the masses updated, I know everyone is just dying to get the down low on these $80 shipped 9" diameter motor 10's lol. Push terminals accept true 12awg wire easily by the way.

Box wise, 1.2 @ 34 might be best after break-in
