Dual SD12 Thiele and Small Parameters

[teedoff00]

Hey this might seem stupid. But I purchased 4 Dual 12" woofers for a '93 Cadillac DeVille that I got for free for a replacement Daily Driver. I have some experience building boxes and such but I need the Thiele and Small parameters mainly Qms, Qes, and Qts.

All I can find is some dimensions (from dualav.com) like the resonant frequency Fs and some impedance information.

Any help would be great as I am going to build the box tomorrow. I know these subs ****, but for 30 bucks a pop at Walmart I couldn't refuse playing around!

Please respond with information or ways I can find it!

Thanks!

For what you paid for those, you could have got something decent off ebay. My advice, take them back, and never do anything like that ever again.

You can get the Hifonics HFI's for 30 bux a piece from onlinecarstereo.com and they sound excellent - i was in my car audio place playing a few in a sealed box maybe half the size of what they needed and they were pounding. Definatly better looking as well with the chrome trim ring. Look them up - take the duals back
