10/12/00: I'm very happy with the finished subwoofer. I will be looking into disabling the bass boost on the amp in the near future. Eric at Parts Express has been very helpful and will be letting me know when the schematic is available. I also hope to add some measurements of some sort in the future. They won't be anything special, probably just a RS SPL meter with a tone CD. Hope you enjoyed the site, feel free to drop me an e-mail for whatever.
8/29/01: I tried the bass boost disable option on the amp. Not as much punch, so I went back to enabling it. I would guess if you had a larger driver and/or a ported box maybe you'd benefit from disabling it. But with a sealed box and a driver with enough X-max to take the boost without bottoming out it works great. I've received many e-mails from people looking for assistance on their sub projects or looking for opinions. I'm more then happy to answer a question, but I'm not an expert or an engineer. I found all my answers for this project in the Loudspeaker Design Cookbook, or at Madisound and Parts Express in their forums. Good luck to everyone with their projects!!
	Thanks, Karl
