You have to take into account basket displacement, strange angles for the Cougar, not to mention if you're doing ported then you need info on port length, diameter, and type. Its a very exact science to create a "perfect" box. I've been doing this for over 10 yrs now and I just threw another box away I did, because it didn't sound "just right". There is software out there, but there is nothing like sitting next to the box and listening for port noise, baffle, or reverb. It takes a well-tuned ear to build a good box...
There is no such thing as a plain and simple ported box. There is such a thing as a plain ****ty ported box, however. Ports are an exact science, driven by 4 speaker variables. Never use PVC for ports, that is a sure sign of a crappy box. Never use round ports (causes distortion in the lower freqs). Always tune your ports over and over and over, so make sure you can remove them until you get it right.true, unless its just a plain and simple box, even if it is ported.
