Sundown SA-15.... Need SD for this Driver

[bbeljefe]

Hopefully someone who owns one of these will answer me soon...

I have an SA-15 ordered but I plan to build a transmission line for it this weekend and I need the Sd of this driver in order to design the enclosure.

In case someone has one and doesn't know what I'm asking for....

I need the measurement from top dead center of the surround on one side of the woofer to top dead center of the surround on the other side.

If someone can give me that measurement, I'll do the rest of the maths.

Thanks in advance for your help!

Oh and, I'll post up build pics and a video of it beating up the inside of my truck when it's done.

I would email jacob to get the exact measurement.

I'd bet it's close to 791cm^2... Very close. I'd use that value for now and I doubt much will change when you get the correct number.

I have 792 cm^2, 122.76 in^2.

I was told 128.93 sq in by another person who measured one. How did you measure, Buck?

And thanks for the responses guys.
