The specs for my box build

[DjFreddyFred 0]

Hey guys,

I have Manny from

http://www.trexcaraudio.com/

building my box for 2 18" btls..and I was just wondering if this sounds correct, his calculations for the box:

19" high

40" across

37" deep

95 sq ins

port is 13" long (tuned @ 32 hz)

and is 11.79 cubes

thnks,

Freddy

(1)What amps are going to be in use?

(2)I think you're about 100 square inches shy of what you'll need for two 18s at 12 cubes

your #s = 16.2 cubes before displacement, minus .7 for your port, minus .26 for each btl 18 so .52 total for subs. So 14.98 after the two not including double baffle or bracing etc.

Fi hasnt posted all the T/S parameters for the new BTLs ,but I can tell you the 18'' btl speaker displacement is .26cubic foot each. Its range is from 5cubes- to around 10cubes. keep tuning somewhere around 32hz with 12-16 square inches of port per cubic foot of air space
