Dual chamber dual ported

[Justin Eaton]

Is anyone using a dual chamber dual ported box? Pros? Cons?

[TRON]

A 6th order?

ABC?

[Justin Eaton]

No, two separate chambers two subs(9515 dds) and a slot port for each chamber

So basically two boxes built together? Yeah they are fairly popular. They work well.

The problem is the box is bigger. Each port has to be longer than with a common chamber. More wood is used.

ok thanks. The box come with the subs and I didn't plan on using it but I might try it out now.

Yeah give it a try and see how you like it. If you don't then your next step is to build yourself a good box. They are DDs, they will probably sound good. Also placement is something to think about. If at first you feel like its lacking, change the position of the box. Sometimes the difference is amazing.

The only other down side is port efficiency

It is way down

So you have 2 ports 15h x 3.5w x 26.75 @37hz

That's the same as a single port 15 x 7 x 22.5 @37hz

Differance is port efficiency

The first has 74" x length of 26.75" =1,926

Where as the second common chamber

Has 44" x 22.5"= 990

So the efficiency of the port is a huge differance
