TRTC360 Posted August 7, 2011 Report Share Posted August 7, 2011 Due that thing justice and put it a ported box. That thing Is sexy. but as far as the interior of a sealed box I doubt smoothing it would do anything. But polyfill would be interesting or maybe second skin????? I might be completely wrong with this but isn't sound deadener supposed to help stop rattles and avoid resonance? don't you want resonance in a sub box? like I said, I might be completely wrong.

kirill007 Posted August 7, 2011 Report Share Posted August 7, 2011 the deadener will do nothing in a enclosure. Its not made for that and it wont work for what you are thinking.

Quiet Posted August 7, 2011 Report Share Posted August 7, 2011 Polyfill will flatten out your response curve, but just a little. It will also reduce standing waves that tend to color the sound a bit. All my first enclosures were sealed, as I didn't have the balls to go ported. I will never go sealed again. With the subs I've used in the past, they all seemed to like vented boxes better, especially when really reaching for SPL. Sealed tends to get muddy when you push it but vented just keeps on going.

I noticed the muddy part about sealed enclosures, using different frequency test tones at least in the two sealed boxes i've tested with every click on the volume on the HU there's a completely different sound on the same frequency, in ported it just keeps getting louder and louder while staying clean, ported FTMFW!!!

S15_Silvia Posted August 7, 2011 Author Report Share Posted August 7, 2011 Until I can have a ported enclosure that stays relatively flat from 30-50Hz, I want to try sealed. All of my previous (L-ported) boxes have some massive output spike in the 30s, and don't put out nearly as much above or below that.

Takes some experimentation depending on the cabin gain curve of your car. Try loading your specs in WinISD Beta to see what you might get. Edited August 7, 2011 by srp365 Quote 2007 Pacifica Rebuild.

Mikesmith0890 Posted August 8, 2011 Report Share Posted August 8, 2011 4th orders if done right have a fairly flat response and a strong bandpass width Quote AlphaDamp Sound Deadening CDL Mat - The best Vibration Damper Ever!

Quiet Posted August 8, 2011 Report Share Posted August 8, 2011 Um, since your woofer is being built custom, you might not have the T/S for it yet to use WinISD, so forget I said that...
