sub out of tune
recently i made a box for my diamond D6 sub. internal dimensions are 38.5 x 12.5 x 8.5, which brings it to 2.1 after sub displacement. i put a 3", 9.25" long tuning it to about 28 hz. this is WAY too low for this sub. I barely hear any notes besides the real low ones. put my ear up to the speaker, and it was making like a squeeking noise when its supposed to hit, but doesnt. I'd prolly do alot of damage if i continued it like this.
which bring me to my next question: i love how ported boxes sound, so can anybody tell me what tuning range this sub likes (for the most flat response), and how much to trim the port, or is there a way to seal off the box to make a small sealed box? i really dont wanna trash this box and make another one, but i guess i could if all else fails.
thanks in advanced,
