I was playing around with WinISD and the 6ft^3, the bash amp, and the infinity driver. It shows the SPL 97db @ 20Hz (about that). Is that possible? I had the signal set from 1w to 150w and that...

Does WinISD calculate Hz based upon manual entry of cubic footage of the enclosure?

When tuning with WinISD, if I change the cubic footage of the box, is Hz supposed to change on its own? What if I change Hz? It doesn't. Yes, that answers me, but how do you tune? I mean there...

On the driver, since you can use an audio sub like the Infinity, why do people by the higher dollar sub drivers? Is it because it says audio and not home theater?

So you just stick an 18" pvc pipe in there? Anywhere, with just a 4" hole out the back? How would that translate to the slot version? The slot isn't going to be 4".

I wasn't sure how you actually built the vent part. I didn't see a pvc pipe or anything. Did it sound good on movies?

Question Can one build a decent sub for $350?

By decent I mean low extension but not boomy. I've never heard an HSU or SVS, and I don't expect miracles, but can something be built to be comparable to these systems?

All home theater usage.
