subwoofer room management

I have a Paradigm Servo 15 sub which had a muddy integration with my Dynaudio Contour 1.8 floorstanders. I elevated the sub onto 8 number 3 Vibrapods, each with a racket ball resting between the base of the sub and each Vibrapod. My flexible suspended wooden floor was also allowing feedback from the sub to the Rega 25 turntable. The racket ball/Vibrapod suspension cleaned up the sound and eliminated the feedback.

Tuning a port reflex cabinet

Outside of the universal calculations to determine the port length is there any way to measure what Hz the box is actually tuned? For example, if the calculations determine that the box should be tuned at 34Hz is there anyway to measure that other than just sticking the required length port tube in the cabinet? Is Figure 31 pointing me in the right direction?

"21st Century Vinyl" - Two Thumbs Up

Just devoted a couple of hours to Michael Fremer's DVD, and I nearly posted these comment in the Raves section rather than here.

I'll play it again some time.
