jmilch Posted July 23, 2011 Report Share Posted July 23, 2011 So here is the current dilemma... I have a 3.8^ft box, tuned to 32 hz per specs for my Memphis mojo quad 1 ohm cm15q1... And it sounds great but... I want some trunk space. It literally takes my entire trunk up. It is plenty loud, so losing a few db's aren't gonna make me cry. But should I go sealed? I am thinking of doing a 2.5^ft box. Now my current box is double 3/4" mdf all around and weighs a shit ton. I'd like to shed a lot of weight in the process here..... So will this make my system sound like shit? I listen to everything from rap to oldies on a daily basis... I've never done a sealed enclosure in my 13+ years in the car audio field (I've built them for customers but never used one for my own setup) Has anyone else made the switch? Will I lose a ton of sound? It's getting a full power audioque 2200d @ 14.5v and loving it currently.... Will a sealed box effect power handling?

neuspeedescort Posted July 23, 2011 Report Share Posted July 23, 2011 being someone how had run sealed boxes for years i switched to vented about 5 years ago. sealed is lame. unless you oversize it (and even then it will still suck) your going to lose your low end response.

jmilch Posted July 23, 2011 Author Report Share Posted July 23, 2011 To be perfectly honest, I have good electrical, nice power, and anything under 34 hz sounds like bear farts. So if I lose some real low tuning mi wouldn't care at all. Does it greatly effect the power handling capability of my sub?

Quiet Posted July 23, 2011 Report Share Posted July 23, 2011 If anything under 34Hz sounds like beer farts then your box is built all wrong... Going sealed generally gives you more mechanical power handling as your sub is less inclined to bottom out. This is the trade for low end extension, and in my experience the sound gets muddier with a sealed box over the same driver in a vented enclosure when you start to push it hard. just my .02 Quote 2007 Pacifica Rebuild.

But when it gets under that point or there about its sounds like bear farts seriously. I was thinking a sealed enclosure would make a punchier response, and less chance of unloading... maybe im wrong?

Socky Posted July 23, 2011 Report Share Posted July 23, 2011 That is correct i would think so, if i remember right you would have less box rise in a seal enclosure. Maybe think about building the new box out of birch for weight loss.

jmilch Posted July 23, 2011 Author Report Share Posted July 23, 2011 Thanks for the tip on the birch. The current box alone weighs in well over 125 lbs. Now the mojo isnt a light sub so I know I am pushing near 200-225 lbs back there. Can the birch be painted like mdf?
