Is this a passive subwoofer? will it work with a 5.1 home theater receiver that has subwoofer speaker output terminals? the receiver doesn't have subwoofer preamp output, just speaker output terminals. I've an Onkyo home theater 5.1 system, with a passive subwoofer that I'd like to upgrade. thanks steve bufftough@sbcglobal.

Hi Steve: This will work perfectly for your application. It can be connected directly to the subwoofer speaker level output on your ONKYO 5 channel amp. TL/5106

Hi Darwin: The fifth image on the web page features a shot of the woofer with its black cloth grill. Our graphic artist added a little highlight to it to help show it off. This is not mean for outdoors. WE are developing an in wall version that is similar 8 and 10 inch woofers with sealed enclosure and white metal grill. We hope to have these in the barn before Summer. Stay tuned... TL/4913

Hi Tom: I am not sure what you are asking. This speaker has an 8" woofer that is active, connected to power. The 10" woofer is a passive Radiator with no power connected. It operates as a tuned port. TL/5275
