HSU Sub

shajan · 12th April 2005, 04:41 AM

I have a driver that came out of a Hsu VTF2 subwoofer. I'd like to build a box for it but I don't have any TS specs. I'll be using a plate amp (300W) to power it.

Any suggestions on box volume or/and alignment will be appreciated.

If you took measurements of the old box it came out of...

For the box, why not just use the same dims (volume) and port as the VTF2?

Using the same box and a more powerful amp, it kept bottoming out. (The original amp had burned out and instead of OEM replacing it, I purchased the PE 300W. Will eventually get a matching driver for it)

Meanwhile, I am thinking of a larger sealed box for the HSU driver but can't decide on the optimum volume..

Well, if it's already bottoming out, it will bottom out in a bigger enclosure that's for sure. If it's already vented, it's even worse.

You could measure the T/S parameters by yourself.

If you can't do that, I would recommend to go sealed, in a bigger box if you want to.

Another option is lowering the gain behind the amplifier to prevent it from bottoming out...
