So I picked up a 12" Alpine Type R for pretty cheap, like $75 new clearance, and I'm powering it with an Alpine PDX 600.1 so it's getting the power it wants. It's in a sealed Sound Ordnance enclosure that is 1.27 cu feet. The Alpine's sealed box recommendations are 0.65-1.25 cu feet. Right now it's not sounding very pleasant, not sure how to describe it but it doesn't blend well. I've tuned it with a DMM, have LPF set to 80hz, and subsonic to 15hz. I prefer the punchy feel to a subwoofer over the booming other subs make. I'm considering switching down to a 10" sub, maybe a JL W3 but I'm not sure. What are your opinions?
