What's system Q? If higher than 0.8 add pillow stuffing to lower it. If not just line the cab to damp harmonics.Quote:

Do i even need to use anything?
Your box modeling program should tell you the final system Q.As for home insulation fiberglass, avoid it. Polyfill is the right stuff.Quote:

Are there T/S for the MFW-15 drivers? Is it the same as dayton DVC15?
I assume the Q will be closer to .7 then .8
>MrKazador is there something less irritating to throat/ears than fiberglass i could use? I have a pound or two of polyfill..
Not that much, fully stuffed would probably take the Q down to well below 7.Quote:

I got .88 Q in winisd... so i guess i need quite a bit of polyfill to get that under .8

Nah. You're cool. I have Unibox set for walls lined (stuffing) and I get a .82 Qtc and that's right at the sweet spot for excursion control. 300w safe per driver.
Are they hooked in series, parallel or powered separately?

It falls apart, and the resulting pieces can get all tangled up in the driver. The only fiberglass that should be used is rigid Type 700.Quote:

In a sealed cab with a Q of higher than 0.8 adding polyfill will lower the Q, when tightly packed by as much as 0.2. This shows what that does to response, blue trace before, red after:Quote:
