Carpeting a box. Output Loss?


Recommended Posts

I've heard from a few people that you can lose anywhere from .1 db to .3, it doesn't make a difference unless you're serious about competing.

some have lost serious numbers some have recorded little difference.. alotta times there is a loss on the meter tho...to the ear tho.. probably not enough to notice

This isn't teeball. YOU DO NOT GET A TROPHY JUST BECAUSE YOU SHOW UP. Put the work in and then maybe get the respect when it has been earned

I did test that on my SPL gains topic, of course, every scenario is different, but i did gained 0.4 dbs by taking out the carpet from a box, you can´t feel the difference on your ears tho...

painting a box generally does nothing to the output..the carpeting basically "absorbs" the sound..best way i can put it lol paint keeps the box smooth so there is no cancellation that way

edit: at least ive never seen a change if someone has do step in just havent had it happen to me

We gained 0.5 dbs by painting the box inside, but i´m talking with a lot of "base" and wax, box ended up been smooth as hell on the inside, just like a car, we haven´t painted it on the outside, gonna do it very soon an see if we gain some more ;)

ya inside makes sense basically same principles as resining the inside and sanding it down to make it smooth..

Yeah, that's why I don't carpet my boxes. I normally take a triple thick gloss paint or epoxy resin and coat it. Turns out really nice (Looks woody and everything)

New build coming soon. [center][url="http://imageshack.us/photo/my-images/3/sigtoo.jpg/"][img]http://img3.imageshack.us/img3/9541/sigtoo.jpg[/img][/url][/center]
