Sound deadener inside a subwoofer enclosure

[audioholic 5,000+ posts]

It is much more important for SQ than SPL. Damping material on the walls CAN help. Not to increase rigidity but to absorb backwaves which can muddy the sound. Sound pressure that isn't absorbed reflects off the walls and affects the output of the speaker itself. Also Acousta Stuff can make a box "seem" 10-15% larger than it actually is when limited space is a concern.

Most decent deadening mat has an alum layer, it wont 'absord' sound all that well (remember its suppose to be a barrier). As I said above, if you are concerned about back waves, the proper way to address that is to apply acoustic foam to the inside of the box. This will be much more effective as absorbing back waves than will a layer of deadening mat.
Again, there is no good reason to use deadening mat on the inside of your box. None.

You're certainly right. I was not referring to deadening materials such as "Dynamat", I was actually referring to acousting foam like "Sonic Barrier" etc. when I used the term damping materials. Sorry if anyone misunderstood.

I've got a 99 rodeo and I've bought one of the Sony XS-L10S, so it's enclosure needs very little cubic feet.

That sucks. Hope you like it though.

Ok, I fully understand....no deadening mat on the inside of the box. Would a closed cell neoprene work (I've got some of that on hand) as opposed to an acoustic foam. I'm not against using/buying whatever is necessary to make it sound right, I am just curious if anybody has ever tried neoprene.

SeanDub,

What sucks? My SUV or my speaker? This is a project truck, but I enjoy Rodeo's. I owned a 94 for over 7 years before a lady T-boned me. Never gave me any problems.

i think he is referring to the sub choice.

I hate Sony. But, I know it is a shallow design that didn't require a lot of clearance...and I got it for a steal ($45 shipped)

Nah I asked what year Rodeo because I have a 04 and I like it a lot. I was referring to the sub *******. But for $45 shipped I hope it gives you the output you're looking for.
