Having decided to order the Tower 2 Pi kits from you, I am wondering if any of the following "refinements" would be of any demonstrable value. Please understand that I prefer to follow the basic plans 100% unless you see value in any of the following:

1) Piezo cone damar treatment to "soften" perceived shrillness. I assume that many people who have performed this tweak probably had woofers that were less efficient than the Piezo, and merely deadened the tweeter to be less efficient and, in turn, that makes it sound "better" to them.

2) Dampening the frames of both motors to reduce vibration.

3) Use of a rear mounted screw/dowel from the back of the cabinet connected to the woofer to help control resonance/vibration peaks.

4) Substitution of "black hole" or felt for the standard fiberglass insulation. Controls backwave better?

5) Use of T-nuts to provide desired tension coupling of the drivers to the baffle.

6) Radius the inside of the woofer baffle hole to provide better air flow.

7) Speaker spikes to couple the speakers to the floor.

Wayne, what gasket material is best for the drivers? Are there any other "tweaks" that you may recommend?

Many thanks,
