box btl n2 15

[dranny]

Hello, sorry for my bad speak, but I'm Italian

I have a btl 215, I have to redo the box for changing car

I can pull it off 3.5cuft without slanting walls, port 32Hz

I was first 37Hz 4.7cuft

you think I am losing pressure? I will have increases in low?

ampli is zapco 3000.1sp

Post your max dims and vehicle model.

Where are you in Italy because I'm also in Italy and I run the BTL 18's.I can tell you that lowering your tuning without adding power will more than likely lower your score also.

I'm in Calabria.

referring to the drawing, the max external dimension for the box in my renault clio III R are:

a: 26

c: 17.28

h: 13.59

alpha:61.8°

beta:79.4°

box lenght: 37.82

port and subwoofer should be on top in "c"

for the simple box external dimensions are:

17.28 x 17.28 x 37.82

H of the simple box should be 13.59"

yes...sorry

Does that amp do rated and at what voltage? What's your electrical like?

If your getting 3000 wrms out of the amp I'd go with 3.5-4 cubes with 55-75 sq in of port.

I know BTL's love lows not so much the highs atleast the n2's so I'd probably tune a bit lower

[dranny]

nominal impedance in amp is 0.7ohm ( btl is dual 1.4ohm )...i've 2 fam80 spl but this amp is super efficient.

So what's the solution?
