closed cell vs. deflex pads
which is better for improving sound quality, closed cell foam or deflex pads?
Ive currently got a dampened door but no absorber of any sort in the door... im noticing a peaky midrange from my edi6500s.
I'm definetly going to choose one of these methods to prevent rear wave distortion.... Just need help deciding which one.
(Ive also heard about some people packing Polyfill around the basket and taping it in place, dunno bout that tho)

Your trying to reduce standing waves right? I would think that the shape of your cabinets will have the biggest effect on standing waves. I used foam on the inside of my car in various places, but not inside the cabinets. Different thickness will absorb different frequencies. I generally use wool or cotton inside the cabinets.

I would try closed cell foam, a deflex pad is only so big...it's ok at catching standing waves, but it's doesn't cover a large enough area...I had deflex pads, and have decided to get r id of them in favor of closed cell foam behind the doors.

ok cool...
so i can go down to the HW store and pick up any closed cell foam and it should help cut down on standing waves in the doors right. I dont have to go buy brand name Luxury liner or whatever from the deadening company.
also how crucial is sealing around the speaker to get the proper midrange/vocals?
I mean sealing in general with either deadener stuck all around the baffle or with non hardening clay (plasticene)
because i currently dont have anything on there to seal up my baffles(theres no obvious openings but im sure theres slight air leakage... and im getting peaky midrange (midbass is good however)

I've never looked for closed cell foam at the local hardware store...I assume that buying it fromon on-line retailer in Bulk is alot more cheaper because they carry more for this type of application...I bought about 50 FT of closed cellfoamonline for about $110-Shipped...I plan on lining my entire trunk with this s tuff to dry t he sound ofmy low end.

I already picked up some foams from the hardware and fabric stores... the closed cell foam was from home depot, i got 20sq ft. for $15, its primarily used as underpad for laminate flooring and carpet in basements, it acts as a vapour barrier..... hope it gobbles up sound waves.

Deflex pads
The Deflex pads come in a variety of sizes up to 13". Focal also make a product called Plain Chants that have even better results.
As for foam? how well does this foam resist water/humidity. I believe it can get a little stinky after a while, but hey whats a little smell when you can save enough money for a night or two out drinking or 1 decent seat at a concert.
