different size ports

Recommended Posts

Is it possible to run 2 diff size ports in one box ? I have right now 2x 4" aeros and need some more port area could I add two more 2" Aero ports to add more port area ? I am going to keep ports same length because I also want to tune a little higher ... right now I'm at 28hz and want to go up to about 32 or 34 hz

You can, but if I was you, I would just add another 4" aero.

Maybe it makes the tuning too high?

Current system:

1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s

Previous systems:

2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz.

1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

Well I have the 2 4" vertical and no room to add 1 more 4" so I would put the 2 2" on the side of the 2 4" and if I have to I would add more length to them to keep tuning were I want
