Sundown Amp Clamp Tests
R_Mac_1 replied to sundownz's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
IIRC it did rated power with a rise to 2 ohms, or something along those lines. It was in a thread a while back, possibly the thread Jacob started when it first came out. Edit: I found the thread. Here's Jacob's quote: -
DC Audio VS Ascendant Audio

Whichever one is installed properly will be loudest. -
I think I remember Dave @ PSI saying that the easiest way is just by testing. You just use test tones one by one. Whichever tone the sub moves the least and the PR moves the most is your tuning. Add more weight to lower tuning and remove to raise it (I think). I'd like to try them but it's a fair amount of added cost.

PSI also sells PRs at fixmyspeaker.com . Just have to shell out about another 100 bucks. I think if you get a PR you are supposed to use more cone area than your sub has...but the nice thing is it keeps the box size very small.

SA-15 would be my first thought. Also the AudioQue SDC2.5 15 would be even cheaper.

Good news & bad news

I remember hearing a lot of bad stuff about AAMCO. Just sayin... -
Why do you need so much port area? If you're using aeroports you don't necessarily need the 12-16 that people usually recommend. In my buddy's 1.7 cube box for his SA12 we used a single 4 inch (which is a little over 12 sq in of port) and he doesn't have any port noise or anything. You could probably use 2 6 inch ports and that would be around 56 sq in of port, which is over 10 sq in per cube.

No, the radius of a 6" port is 3". 3 x 3 x 3.14 = 28.26 sq. in. You were using diameter.
