Any pictures/box plan of that dimensions for a single Type-R?

Why not just build a vented box according to the recommended parameters out of the Type-R manual?
Outer Dimensions: 18" x 13.5" x 16.5"

Vent: 12" x 1.25" x 22.75"

Gross Internal Volume: 1.7 cf

Might be worth a shot.

exactly. that's what i would do if i was in this dilemma of his.

check your subs manual, usually they have box plans from least amount for good bass to best bass performance and check the Alpine website.

i said it twice. the type r's are upper middle class subs. i bounce quarters off the roof and that's sealed. a proper ported box would get loud. install is everything.//content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I just dont know, its possibly either my hopes were set too high, or everyones prediciton/idea of a box at 2.5 cu.ft. at 32 hz is WAY overrated. At least in my opinion. I may just try to build a ported box, or maybe ALSO sealed if I have enough wood/cash, and see which out of the 3 box's I like best. But until then, Ill also save up for a another Type-R subwoofer.

AND: Is having the gain set at 50% bad, because I cant figure out for the life of me how to set the DMM and such. It doesnt sound distorted or clipped or anything of that nature at 50%. Will I be ok?

i do all mine by ear. i run sealed though. ported is a little tougher. i also spend many hours tuning my system. it seems that i'll never be satisfied. my next project is 2 FI Q's sealed, and some better comps. i'm sure i'll find something wrong with those to. it's a never ending hobby. have fun.

Your joking,right? TCAB boxes were nothing spectacular. There is no magic trick to building a ported box and his werent' that great, sorry. People who purchased them have attested to that.

Personally I think your expectations were too high and that's why you were disappointed. Type R's are nice subs for the money, with a emaphasis on the latter part of the sentence. They can get loud with the right box as with many other subs. I'd say experiment with a few boxes, and if it doesn;t fit your need, sell it and find something that does. You could prolly get a L5/L7 for not to much more than than a Type R. Get a 12, port it, and it should get loud enough for you off 1500+watts. SQ will be acceptable in the right enclosure. Im sure there are other subs that fit you bill but I can only speak of the ones I have heard/used personally.
