Hi Guys... Looking to build a soundproof recording box...

Hi Guys!

I'm looking to build a soundproof box for closed mic recording and i found a link to someone who built a box around a 4x12 marshal cab and was thinking about doing something similar....

I've already built a 2x12 cab for practice room use and my old 2x12 amp is still loitering about but knackered so i can't really sell it...

http://allthenameshavegone.blogspot.com/ this is my blog from the build... I'm sooo rubbish at keeping it up... but it gives you an idea of what the cabs look like (precovering..) but what I was thinking of doing is closing the back up, lining the cab with 1/2" polyethelene foam, pushing the baffle almost as far back as possible and try to mic up both of the speakers for stereo recording.

would this be soundproofed enough? doesn't have to be silent but i would like to be able to crank up the amp and record from there... I understand that the .... umm... not sure what you call it but the sound may be a touch dead so I can add on room effects afterwards and learn to shape the sound for a more recorded feel...

The head I'll be using is an 18w one i built from a kit... sounds awesome... but I want the cab to sit under a desk so that i can just use my normal head with it....

OR...

should i just push the baffle back in the cab and build a box around it with the foam lining?

OR....try sticking the amp in a small clothes closet that has a good deal of clothes/stuff in it...crank the amp...close the door, and see how that works for you...

...before you break out the lumber and saws.

i'm a fan of lumber and saws!!! I seem to have an abundance of both!!

I don't have the space to use a wardrobe... that's why I was planning to build it into a box so that I can stash it and forget about it!! lol

If you have no other choice...you gotta do....

I just figured that if you have a closet...then no need for a big "iso-box" in the room.

To get any sort of soundproofing at all, you need to be totally sealed. That means a tight gasket and latch for the hinged lid and some sort of caulk where the mic cord and amp cord enters/exists.

You need heavy, thick wood. A foam lining would probably help. Do whatever you can to keep as much of the speaker cabinet from touching the enclosure as possible. Like, make the feet as small as possible and set them on the springiest substance possible.

You might want to go double walled...but give one wall a shot first.
