SVS 12.1 ISD Subwoofer T/S Parameters

Hey all,

Anyone know the T/S parameters for these drivers? I actually asked this about a year ago but cannot find the thread. I know Tom at SVS doesn't like giving them up (and I don't really blame him). Someone long ago (Robert maybe?) told me they were very similar to a TC Sounds driver, whose parameters would be sufficient. Even those would be great.

Thanks for any info!

The ISD drivers are probably more closely related to the Beyond Audio X series drivers. Both were built by Destijl Engineering. I'll have to look up the parameters on my other PC in the morning.

The older TV and older Ultra series drivers were the TC Sounds models. I have a pair of older TVs that are going into a pair of sonotubes. My older Ultra was lost by FedEx somewhere in Ohio.

That would be great. Thanks Robert. Somehow I expected you'd be the one to know

That's a bummer about your lost drivers. I hope they were insured. UPS is usually very good about that kind of thing. I have no experience with FedEx but I'd assume they would be as well.

The parameters below come from a Blueprint 1201. Same frame, cone, etc as the other drivers mentioned except it uses XBL^2. A guy that goes by the screen name TeamPSI used these same parameters when selling a Beyond Audio 12. I trust that he knew his information since he worked for Scott Atwell at Destijl Engineering.

If you really want to know, you can also send me the driver and I'll check it with Woofer Tester 3. Pay shipping both ways and I can do it over a weekend.
