Hey guys I have a question I bought 4 3 inch aeros to be tuned to 31 hz they are going to be 12.3 inches each will this sound good I'm using a saz 3000d witha cascade designs omega 18 itshould pound right thank to all who help

It will sound like crap and won't pound at all. You have ~28 sq in of port area. That port is going to compress and you will be hearing a very leaky sealed enclosure.

For an 18 I would use atleast two 6" aeros...I would use atleast three 6" round ports. So you need atleast four more...but that would be stupid.

using an 8" sonotub would be much better and cheaper

You will probably need more port area.

What about 34 hz with 4 3 inch ports

Cascade-designs.com the t/s are there

Can you not read???

Regardless of what your gonna tune your box too your gonna need some more port area so focus on increasing port area.

If you are going to use 3's, I wouldn't use any less than 7 of them which makes no sense IMO.
