Dynamat as subwoofer enclosure damping?

And I'm **** good at it too!
I learned this approach to online forums way back in the daze of Usenet Newsgroups. I still drove a few of my last aircooled VWs and started to frequent rec.autos.makers.volkswagen.aircooled (RAMVA!) and I lurked a while as I always do before posting my first post. When I made my first post it was asking a question about people's experiences with dual carburetors on them. I posted a very polite inquiry and got almost NO response! I rethought my strategy and reposted but this time with the title of my post "Dual carburetors ****!" and then IN my post started off "Now that I've got your attention..." and them I said something about that I had posted before and reiterated my request for information. I got a LOT more responses, one even from a guy who said he'd seen my first post but didn't reply to it!!

So it's people's very tendency not to help at all online unless provoked that shaped my Internet personality! :) Like me so far?

So you were one of the very first internet trolls back in USENET days. Congratulations for being a pioneer, you'll fit in fine around here. I lurked this board a couple years before posting myself and I can assure you it has ALWAYS been trolling and nuthuggery.

That said, if you built your box correctly it is already inflexible and airtight. If it is not rigid you need more layers of wood or bracing, if it is not airtight you can remedy, that with caulking, glue (making better cuts to start with), or flooding/coating the inside with polyester or epoxy resin. If you want batting you should use poly-fill, though apart from T-line it has NO PLACE in a woofer box. While you can "trick" a little more low extension out of a system with it, I find you do not gain the extra output that would come from using an actual larger volume of air .

Just sit back and apply some logic. If you "need" butyl/aluminum deadening in a box to begin with you missed something in construction that could still be remedied better and cheaper with other materials. At 3$ a square foot and up, even if it would "help" something you probably have better options.

 
how about no one lines the inside of a box with dynomat

your box builder you chose to pay to do this said no

we say no

accept it at face value and move on

or don't and pay him to line your box

You're reading comprehension is not so great, eh? No, I said my installer guy didn't want to do that! It was my idea, which I now realise would not be beneficial too much at all as damping sound pressure waves is not what Dynamat is designed to do!

Not surprising, as most of the testosterone fueled idiots here into "boom cars" are about as speciously brilliant as people who put truck testicles on their trucks! DUH!!

Careful, John. Troll too many forums and you leave a trail.

Hee hee! Didja check out my Facebook account? I have faked or deleted most all of my personal information in Facebook, including setting my Facebook gender to female! And that was before I was running Adblock Plus and FBPurity and was still seeing Facebook ads!! It was amazing to me the change in ads I saw by just switching my Facebook genders!! Disgusting actually!!

Isn't Dynamite supposed to be more of an insulator? Sounds like a good idea with mids and highs for a softer and less wide-spread sound, but 100hz and below will have less resonance with those deeper tones that the unlined box is designed to harmonically balance. Physics aside, it always boils down to our ears.
