As far as the distortion from overdriving the speaker, I'll admit that I'm surprised. Not that the speaker bottomed out (that can happen to any speaker), but that you were playing it that loud. You must have them in a pretty big room as I use a 30wpc Marantz and have never gone beyond half way on the volume. Like Flo said, turn it down

Interesting stuff I didn't know about the VR-1, thanks for pointing that out. I would be curious as to how the driver behaves at the lower limit using that kind of design, since typical ported speakers have the minimum cone movement at the tuned port frequency and uncontrolled movement below the tuned frequency. Is there any point at which the driver can unload, or does the cone remain dampened throughout the bass range?

Not that I'm asking you to run a frequency sweep at reference levels or anything like that!
