Hi, I have this sub kicking around. I want to start putting some low end into my system. Can I start with this to build anything decent? My room is 18ft x 20ft x 8ft.

I would like to use a TEAC stereo reciever to power it temporarily. It puts out 75wx2.

If I'm able to use this sub and amp my INITIAL costs would be minimal. I would, from there, upgrade accordingly.

appreciate any input,

Some specs:
Model S12c-4
Nominal Impedance, ohms 4
SPL 1W/1M 88.28
Displacement, cc 1953.33
Displacement, Cu In 119.2
Hole cutout, in dia 11 1/8
Mounting Depth, in 5 5/8
Revc 3.365
VC Inductance, mH 0.606
Sd, SqM 0.0511
BL 12.243
Vas, Liters 212.5253
Vas, Cu Ft 6.01798952
Mms, gms 128.089
Fs 18.575
Qms 9.338
Qes 0.336
Qts 0.324
Pmax, watts 600
Xmax, mm 8.51

If you want to upgrade in the future, The Kicker in 6 cu.ft. tuned to 18 hz would be about as much low end you can get out of it considering its 8.5 mm Xmax. In the future a Shiva-X takes its place. Here's a graph of the spl of the two. The Kicker can handle 75 watts with a subsonic filter at 15 hz and has 103 db at 20 hz. The Shiva-X can handle 600 watts with a SSF at 15 hz and has 111 db at 20 hz. If you went this route, porting would need to be two 4 inch flared ports 32 inches long to accommodate the Shiva-X air speed. Be aware that 18ft x 20ft is a big room, you might need a second sub, depending on your needs.

Mike P. makes a good summation and recommendation.

What is up with the two specifcations below? 212 liters does not equal 6.02 cubic feet! 212 liters is 7.49 cubic feet. 6.02 cubic feet is 170 liters.

Does the woofer behave differently in countries which use the metric system? :dunno:
