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,

Is this sub a single 4 ohm coil?

I want to start putting some low end into my system.

As in music or HT or both?

What else do you have in your system?

It's a single 4 ohm coil.

As in music or HT or both?

Lets go with all HT as my fronts have 10" sub built into each which I think to well for music.

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:

Your right, it should read Vas 7.51 cu.ft.

Thanks Mike this is exactly what I was looking for.

Can you tell me what length port is required for the kicker?

Thanks again!

The Kicker needs one 4 inch flared port 14.5 inches long to deal with its air speed. If you're going to use a Shiva-X in the future then install two 4 inch flared ports 32 inches long now and you're done.
