Paint, not carpet?
Hey guys. I'm nearing that awesome time when I get to make my latest audio endeavor a reality (YEEEEAAAY!) I've decided that I'm gonna build the enclosure this time to save some bucks and get it just how I want it. What I'd really like to do is not have it carpeted, though. I wanna round the edges, mud the seams, sand the shit out of it, and do a sweet paint job!! However, I wonder how this will affect things acoustically . I know a carpeted box will reduce reflections, but would I actually notice the difference? Am I likely to get any more noticeable cancellations or anyting like that? Thnx
what if the hokey pokey really is what it's all about?

oooooo, the texture of that bed liner spray would make for some nice accents if properly placed in the design thnx for the info and the idea!

The outside of the box is all up to you, as it does not matter. What is on the inside is a whole different story...

What do you think of polyfill? Is it true that it actually shows a bigger surface to the speaker than the housing itself has?Eric D wrote:The outside of the box is all up to you, as it does not matter. What is on the inside is a whole different story...

I always use it on boxes where people are after SQ. I always use it on my own boxes.joerg wrote:What do you think of polyfill?

Honestly, I don't know if it makes all the difference, but I still use it.
When I build a box for myself, I make it from 3/4 MDF, then I brace it with more MDF. I then coat the inside with VB-1, and fill with polyfill when dry.

Re: Paint, not carpet?
you would have to be made of gold to hear the difference in a carpted box or a painted one.
what else can I say I am a grumpy asshole most of the time.

Re: Paint, not carpet?
eh the whole gold thing just seems second rate now... maybe platinum or titanium sounds better since golden one brought that whole color down.

Here is an article on box stuffing from 1995 Car Stereo Review......

Re: Paint, not carpet?
its a spray or paint on sound dampener. ads a sort of rubberized texture to things

Re: Paint, not carpet?
I've heard of that spray...dont some people actually use it to deaden their vehicles instead of press on matting? I'm actually thinking of using some roofing shingles inside of the the box because of is deadening qualities. I have access to a bunch of it and i was thinking I would put down a flat layer, then some angled "fins" on top of that...then i get deadening AND deflection Still not sure if I'm getting the RSdC122's or the Pioneer Champion Pro's. Kinda depends of whether or not I can get my hands on any of the RSdc's or not. This will dictate if the box is sealed(rsdc's) or ported(pioneers). If I end up going with the pioneers, I'll be back for some help designing it Thnx for all the input guys

Re: Paint, not carpet?
roofing shingles inside the box? I would just save the time, not sure what that will buy ya.

Re: Paint, not carpet?
Don't use shingles, they fall apart.
Only a liquid or spray would work in the box, as anything self adhesive (like Dynamat) will not stick well to MDF. Unless you paint the inside of the box, then it might stick.
I have built literally hundreds of boxes when I worked for a local car audio install shop. Only a handful of them had polyfill, and none of them had any internal coating (unless they had a plexi window, then I painted the inside of the box). The majority of them sounded just fine. Going the extra mile on your own stuff makes sense, but there is a point of diminishing returns.

Re: Paint, not carpet?
I have used rubberized undercoating (maybe similar to VB-1) inside boxes before, however, IME if the box is built and sealed properly it makes little difference. I have limited experience with the rubberized undercoating because it can be messy and become brittle and dry over time. Perhaps others have had different results or used superior products?
If you read up on acoustical transmission lines and the varying theories behind such enclosures, fibrous stuffing has major effects on sound output. However, these impacts tend to be more dramatic at higher frequesncies than most of us would send to a subwoofer. (transmission lines are often used in full-range, home audio applications where a single speaker is employed to reproduce all of the frequesncies being played.)
but to get back on topic, a painted box IMO looks way better than most carpeted boxes. I emphasize the word "most."

Re: Paint, not carpet?
wow, that mirror finish looks awesome! I won't be putting that kind of time into the project, though I was gonna bond the shingles inside with silicone or wood glue, but from what you guys say, it won't be worth my time so I guess I'll pass on that. I'm still gonna do a nice paint job on it though thnx for all the info!

Re: Paint, not carpet?
How about hot tar & gravel on the inside? Pour it in a hole and roll it around to spread it, now thats damping!
