Inverted Sub

i have an orion h2 15" dvc sub. i want to invert it when i make my box for it and my question is does inverting the sub make a difference in the recommended size of the box. are there any special things that need to be done to make it sound right besides reversing the wires instead of + to + and - to - ,do + to - and - to +.98 Cadillac Deville

one thing i would suggest so you dont have the surround in contact with the box i would get the plain that has your cut out for your sub before you put your box together and put your sub in on the underside of that and then put the box together that will help you get a good seal also1974 ford pinto 4 15" punch Z power punch bd 1001 pioneer DEH-6700

Well, you could double-face your box.  You can build the face of your box where the woofer will mount, then build another one that will sit around the outside of the woofer's mounting flange.  This way when you invert the woofers, there's no guess work involved, and they're automatically centered.  Blowntweeters' way would work, but you'd have to rip the box apart to get the woofers out of it.My ex once told me I have a perfect face for radio.

Oh yea.. to get the precise volume of your sub all you have to do is dunk it in a bucket of water and measure the displacement! Easy peasy!"I'm finished!" - Daniel Plainview

I found many advantages in inverting the sub. First of all, more airspace inside the box. With woofers reaching .1 cubic ft on average, and higher... every little bit counts! Secondly, it rids of the need for a grill. Its much harder to damage the rear of a sub than the front of one. Third, it will help keep the driver alive in both short terms of high power or long terms of regular power. This is because the motor gets to draw in cool air from the outside. Inside the box, air temps will rise and only get hotter as the sub is played harder and/or longer. Also, if you are abusive, you can easily smell the VCs heating up when inverted. There are downsides though. First of all, its more exposed wiring. This means something can become disconnected easier. Secondly, at higher volume usualy, you can hear motor noise in some subs (whether its tensil slap or VC movement). Not all subs do this, though. Finaly, it has a great risk of damage to the motor assembly through means of somebody being a jackass and fooling with the vent hole (such as stuffing something in it or liquid poored in there). Either way... i run mine inverted for obvious reasons, especialy being a sealed box and running a bit more power than RMS. Only way to truely see if you like either way is run each way for about a week and figure what works best for ya!04 dodge neon SXT
