Random Theory Question

[99Wolfsburg2.0 10+ year member]

I'm been thinking about this for some time and I'm looking to you guys for some opinions or answers. If a sub was put in a sealed box and then there was a box attached the the face side of that box what would happen? Basically it would be like a bandpass box but the bandpass part wouldn't have any ports so it would be a sub with two sealed boxes built around it.

What would this sound like?

Would it damage the sub?

What you guys think....it ever been tried?

Basically, you're sealing the sub inside an airtight box.

It's going to sound like shit...you're isolating both the front and back waves - the sub has to work against an "air spring" going both ways.

You need an opening somewhere //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

yep. imaging putting your stereo in a room.

then walking outisde it and closing the door //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

thats one way to guess how the SPL would be //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

but you CAN build a horn box, where the cone is sealed, and the rear part is a huge port. kinda cool.
