Mmm, if you had placed drivers on opposite walls, you could have reduced "swaying". As it is, if you reverse two of the drivers (preferably non-adjacent drivers, like FRFR or RFRF) so that their motors are on the outside and drive them out of phase, 2nd-order harmonic distortion will be reduced.
I don't think you could suspend something in the air using sound waves, as the compression of the air is followed by a rarefaction. A constant flow could do it.
For the fronts I would definitely recommend the CDT Audio CL61a from thezeb.REMOVEcom at $150. Rear fill isn't necessary, though if you really want it Infinity isn't a bad brand for coaxes. A single 15" (like the Adire Audio Tempest) will go only slightly less loud at max power than 2 12"...
David, I don't understand why it's so difficult to believe that you can send to a sub any amount of power under its rated maximum WITHOUT DAMAGE. When you underclock a processor, does it get damaged? No, it lasts longer. What about a house fan? Does it die faster when you choose the slower...
What kind of speakers fit up front? If you have 6.5" holes in the doors, you can't go wrong with the CDT Audio CL61a from theREMOVEzeb.REMOVEcom. I don't really know much about coaxials, though (seeing as most rear fill would be coax). I'm not recommending thezeb because I work there or...
How did you calculate the internal volume without the dimensions of the ports? The port dimensions depend on the tuning frequency AND the internal volume of the box. IMO, vented enclosures are better for car audio since you can't really hear the difference between a sealed box and a vented...
Sensitivity is how loud a driver can play with a given amount of power. The higher the sensitivity, the more "efficient" the driver. Vd is the maximum SPL limit of the driver at any given frequency. So if you have a driver with a Vd of about 3L and a sensitivity of 88db/W@1m, and a driver...
Any quirky things I should know about before I calibrate it with the assistance of my AVIA DVD? Also, how do I get into the service menu? Thanks, Howard
