well my box is getting made right now and should be done in a few weeks probably because the guy who is making it is kind of busy building at the monent. i have a small sealed prefab right now while i wait for my box to be built. the subs are two 12 inch rd sonance v1 promo subs (built to do better on low power) running off of a fusion 2000.1 (probably about 1100-1300 at 1 ohm). my question is will i be safe to run the subs in my small sealed prefab enclosure and not damage the subs. the box isnt too too small but i think these subs might def. need a little bigger and more air to breathe. what do you guys think?
That sealed box is pretty close to ideal for the Sonance, in fact if your guess is fairly close it's actually a bit bigger than they recommend if I remember right. You'll be fine.
If you are ever in a situation where you think the box may be a bit small, just throw some dacron sheeting in there.
