If I were to run 2 SSD 18"s off of my 2 9.1's strapped (2400w+), what size box would I need?

13-15ft^3 at 32hz.

That'll give you a f3 around 28hz.

Hmm I don't think I can fit that much in my Exploder. What is f3 again? I've forgotten //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

The point where you're -3db from the reference level.

Hmm you think 3 6" aeros would be good enough for port? Seems to me like it would be.

I'd either do four or a slot port. Three is just too small, only ~6in^3 of port per ft^3.

Dang. That's pushing the limits of what I have for room. I think I'm going to stick with 4 12"s.

You could always do a slot port and not have to worry about accommodating those big flares.

I just don't have the room I don't think See I have to mount my amps and batteries somewhere. Doing a 12+ cubic foot box with a slot port is going to add another 3-4 cubes (assuming 16 in^2 per cube, rough guesstimate), so 16 cubes is about all the space I have back there without having the box come up too high.

Id go smaller... Probably around 11 cubes of airspace. Tune around 30-35hz.

Why would you go so small?

Bump...

Because every time I build a box for them, the smaller ones always work better.

Not arguing just curious. How do they work better? You mean better sounding, louder, what?

Louder and less peaky.
