Hi there. I was wondering if it was possible to build a sealed box where both ends of the sub are sealed instead of just having one side sealed? if so what would it sound like. I want the tightest bass possibe!

I think that will not make much bass at all.

Yea... an enclosure with both ends sealed would pretty much be a vibrator...

If Haem built it, it would not vibrate.

Not quite enough bracing! dual end sealed box for sub -- posted image.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Wut it NEEDS is a Plexiglas window and some LEDs!

technicaly when a sealed sub enclosure is in a trunck isn't it theoreticly sealed at the opposite end? althow the sub enclosure is 1.5 cubic feet and a trunk maybe 15.....(just a guess) I am thinking I could seal the opposit end as well......althow maybe with more volume! what if I used a diaphram at the one end?

Play your system and hold your hand on the speaker enclosure.  Notice how little it moves.  Now close the trunk, play it again and hold your hand on the trunk lid, and the fender.  Notice how much more the trunk lid and the fender moves.  A particle board box will flex very little.  Your idea will make no sound.
