I need the perfect TypeR 15 volume
#1
Im gonna be running 2 alpine 15's on an m1000,
sealed enclosure. (i think ported sounds like ***)
anyone out there done much with them? Im building the box and right now would be a perfect time to get the volume just right.
Would it be advisable to build it a little smaller or higher than alpine specs? Why?
thanks everyone

the larger volume will yield more linear deep bass extension at the slight sacrifice of power handling, the smaller volume will give you better upper bass attack at the sacrifice off deep bass extension, 2.5 cubic feet gross works very well with the swr1541d, is that the woofer you have?

i am gonna be runnning the 2 1521d's off an m1000
(we had the 12's set up off the m1000 and cooked one at the show in the caprice)
i listen to alot of techno, and like the cleanest bass possible, but i went with 15's to achieve lower frequencies. what would be the best medium would you think without going much higher than 2cu ft?

Have you tried contacting Alpine? The thing that I found strange with the Type R/S subs was that they give very vague box recommendations. I ran the numbers through Bassbox, they recommend 2.75 cubes for the pair, sealed. That would give a QTC of .57 which is very flat. For a QTC of .707, it recommends 1.4 cubes for the pair which seems ridiculous. I read a report on the Type R 10", they ran it in .6 cubes sealed I believe it was. Alpine recommends anywhere from 1.3-2.5 cubic feet per sub. 1.3 per sub = QTC of .579. 2.5 cubic feet per sub = QTC of .487. [img]graemlins/dunno.gif[/img]
