I finished my Tempest sub last night. It is 122L sealed. Took me like two days to build, but 8 days waiting for the Tempest to get here from Adire; they shipped it on time, but it took UPS that long to get it to Ohio. I haven't had that much time to listen to it. I watched the Lord of the Rings last night with it and was blown away. This is the first time I experienced bass I can feel in a Home Theater environment; I like it For movies this thing rocks. Then I listened to a little music. The bass is really tight and accurate, not boomy what-so-ever. But I am not just getting the thump I want. I assume the solution is to mod the amp for some bass boost in the 30hz or so range, but I don't want to do this and comprimise movie fidelity. Is there anything else I can do? For music I already maxed out the level knob on the amp, when it was at a little less than half for my movie calibration: speakers at 75db, sub at 79. Well here are the pics. www.markfitzsimmons.com/sub/ Notice I flushmounted the sub, its hard for the pics to reflect it but it looks amazing. Definitly worth the extra time. It's really easy to do, because the height of the Tempest is .75" so get a sheet of MDF this thick and you're in business. I still need to beautify the sub, which I'll probably get done in the next few days, but for now I was just itching to hear it so it's naked A special thanks goes out to Dustin B who answered nearly all my questions for this project. It probably wouldn't have happened without his help.
