SQ Question

The T/S parameters given by Diamond are at 8 ohms (VCs in series.)  This is true for most loudspeaker manufacturers' ratings for DVC woofers.  When you put VCs in parallel, the Qts changes.  Here is the formula for parallel VCs: Qts = Qms*Qes/(Qms+Qes).  The difference is generally not so significant to cause major changes to enclosure design in car subwoofers from what is achieved using the standard series number.

Thanks, I figured it was something like that.  Just take the Qms and Qes and treat them as if they were in parallel.  I guess it's time to hit the drawing board.  Thanks guys, I appreciate it.  I'll let you know how it turns out.
