DIY Subwoofer Help

Hey Peps,

I'm getting a little old for such a loud car audio system and have a Genesis Audiophile 30.01 driver spare and am considering building a sub to replace my little Kef PSW1000.

I was thinking something along the lines of a small sealed box with a BK300 amp panel.

I could simply make a box from 1" mdf but i don't really know how the volume or dimensions of an enclosure effect the sound. So i am asking if anyone out there could design or help me design a simple sealed enclosure.

Below is a link with the tech specs of the driver:

Thanks guys and gals.

Chris.

Hello Chris

At first glance this drive unit requires quite a large enclosure at 126 Litres. Is this going to be a problem?

P.S. I think a moderator may put this thread in the DIY section

how did you work that out? I just had a 30 litre or 1sq ft enclosure when it was in the car.

Hi Chris

I quickly run the parameters through a simulation program, there are Free programs to be found on the web a good one is WinIsd and it can be found here :- http://www.linearteam.dk/default.asp...load=winisdpro it works out the cabinet for a Q as near to 0.7 it shows you loads of details about the performance of the speaker cabinet volume, SPL Etc. unless I had finger trouble and input the wrong data then unfortunately 126 Litres it is
