Looking at the graphs that were added into the thread later....personally I don't think I'd mess whith the 'turbo'. Looks like it makes the response curve slightly less smooth.

The link works now...I left a message for you in your Turbo thread at the HSU Forum.

Hi Jason

I know what you mean about wanting more of the slightly higher frequency bass rather than the <22Hz stuff...if I were you, I would see about returning the Turbo and seeing about getting a MBM...

something weird happened to my original post...

When I bought an SVS 25-31PC I found that I was happy with extension down to "only" 25Hz. But because of all the flap I see on the net about getting the last octave I've upgraded to subs with more extension - first a DIY sonosub tuned to 21.5Hz, now an IB sub that's flat to below 20Hz. What I've found along the way is that the 25-31 gave me plenty of extension to begin with. With the IB I've gained more SPL (mostly bragging rights) and a stealthy sub install. But the SVS sounded darn fine to begin with.

I've often wondered how much of the "max extension" argument comes from people with actual experience with different sub tunings. That thread on the HSUresearch forum is a good example of this. I think the most significant comment comes from the guy who made the graphs with and without the turbo:

"If I didn't recalibrate I had a 3dB difference between with and without turbo."

3dB!!! That's huge! How many turbo users realize they're sacrificing 3dB of headroom across most of the range? I'm sure its fine if you're in a smaller room or have multiple subs.
