12 Vs 15

[Dale]

well i changed around my measurements, if i go with a less depth box like 13 inches, i can go taller box like 22 inches. and 42 inches long, and get just over 4 cubes. but whats the min i should make for 2 15's?

the min I recommend for 2 15s....after all displacement is about 7-7.5 cubes

ok to make it easier, i just went and measured up, max depth i can do is 14, max length is 44, and the height i can do is 22 inches to keep it level with the rear window line. so i can get a box 4.99 cubes 50 square inches of port. @ 32 hz. 4 inch wide L port. or i build a different style port. doesnt really matter. subs forward port up?

so would 5-5.5 cubes be ok for 2 15's? BL's? or BTL's? im getting the new sundown 3500 and want to use its full power @ 1ohm. so i want 2 15's that can take it. but im scared i dont have the room for 2 15's

you should better take the 2 12 inch BTL's , if you wanna get louder later, you can still add a extra 3500.

2 15's aren't gonna work, you need around 3-5 cubes (each). so you would better take 2 12inch they only need 3.5-6 cubes, so around 5 cubes will be enough.

what would be the minimum? because i could always take out my rear deck i made that my sub box sits on. and i can get just over 6 cubes. but if its not going to be as good then i guess ill have to scratch the idea of 15's witch sucks as ive always wanted to try out some 15's before, and the 2 12's would be louder then a single 15.

and if i get the 12's what would be my better option i know its been asked a million times but the BL, BTL or LVL 4 xl's? i want to use the sundown 3500d to its full advantage at 1 ohm. im thinking of going with the BTL's as they seem like they would handle it best out of all 3, p.s it would be fully loaded.

if u cant fit the 2 15s maybe u could do 3 12s.

u could do 3 12" lvl 4xls with dual 1.4 coils = 0.933 ohm load...

I think the lvl4 xl's could handle the 3500d.

But maybe it's safer to get the BTL fully loaded,the 12 inch subs, you could make a better box for them, then for the 15's.

You can make a box that's 16.5 inch high, 37 inch wide, 14.2 inch deep, that's around 5cu ft.

With a port that is 4 inch wide and 15 inch high, and 22inch long.

Don't mind the "BTL 18 inch", it is the 12 inch T/S parameters that i entered, just typed 18, bu ti assure u that it's the 12 inch.

yea i thought about it all day at work today and i think thats what im going to do 2 BTL 12's facing up, port up also. i can either do that or 3 10" BL's but i think the 12's would be better. thanks for the pics. im just no good at designing thats all. and i typed in those demensions into a box builder i have and its only reading 2.34cubes at 49hz

16.5 inch high, 37 inch wide, 14.2 inch deep

these are the inside dimensions, not the outside, what box calculator are you using.
