actually it is now two different subs:

1) Infinity 124.7 Kappa 12"


2)Quantum QCW15D2 Cozmic 15"



I'm building boxes for these subs. The 15's will be in a common chamber box (unless that is not the best idea) sealed.


The 12 will just be mounted in the box.

Thanks,

What sub?

Most of the time its listed under sub displacement.

take a thick plastic bag, put your speaker in it. fill up a 5 gallon bucket with water, set the sub in it. take sub out, measure the amount of water missing...

= displacement

Sometimes its listed, sometimes its not. Its not technically a T/S spec.

Usually you just have to take a wild guess comparing off known speakers/displacement.

For instance my 15" SS SPL170 is about .25 cubic feet.

What subs are you trying to guess?

Okay gang, I know I should know this but, in the T/S parameters where do I find the displacement of a sub.

How is it lableled....???


thanks
