Hello,
Recently there have been 21" drivers released that are little less expensive the the Eminence NSW-6021. One is made by Dayton and the other by Lavoce. I understand the simplex 21 was designed for the Eminence but I figured I would ask. Would it be worth it or even possible to keep the box volume the same but change the length of ports to accommodate either driver? I "played" around in WinISD using the Simplex 21 enclosure specifications but results didn't warrant the the savings of $300, at least for myself.
However the Dayton seems like a decent driver for the money, maybe it is worth a modification even as a home theater model.
Let me know your thoughts.

I've never looked at those plans. Wow what a monster driver the Eminence is!
I don't understand why you wanna redesign it. The Dayton driver will work based on the recommended specs.

Re: Simplex 21" Drivers
+1
Specs are indeed really close.....other than xmax.....21mm for the Eminence and 11mm for the Dayton. Have to keep the voltage within reason....of course, wanting a 21 in. driver means that reason is pretty much left the barn, right?

Re: Simplex 21" Drivers
The Fs and and Qts are close enough, but the Vas is about double on the Dayton (442 Liter) compared to the Eminence (225L).
At less than half the price it might be worth the trouble... but with the shorter Xmax, I doubt it would beat the recommended driver the the S18 - Home Theatre.

From what I understand of VAS is that the Eminence is a more efficient speaker and needs less power to move the cone to produce the same results. Please correct me if I'm wrong.

Re: Simplex 21" Drivers
Vas only major effect is on the size of the box.
Re: Simplex 21" Drivers
I did notice that the Dayton vented volume is almost 3x greater
