"Unlike Rick_m, manufacturers live in the real world."
Odd comment... My point was simply that the steps that you are taking basically have to do with improving the integration of the speaker driver itself to the cabinet. And I was being supportive of your efforts as I too have found that to be a critical factor, especially WRT secondary radiation from boundaries. The business with putting an elastomeric membrane between the rim of front mounted speakers and the front panel is also very important. Actually gluing it down is OK too, the rub is if it rattles even a little enough sound is generated to be distractive albeit often not heard as a discrete source.
As far as manufacturer's living in a more real world than mine, I haven't a clue what you are talking about and having spent my whole working career in various electronic manufacturing outfits I'm really pretty familiar with them.

Rick_m,
Please accept an unqualified apology for a rushed case of mistaken identity with the author of comments on other threads who repetitively damns the very concept of tweaks without apparently burdening himself with experience. You have indeed been supportive.
Today tightened the spike sockets themselves that were surprisingly loose as it appears had also been the screw sockets holding the outriggers after four years. Then jammed a narrow, multi-folded wedge of Teflon tape against the length of each spike before before screwing the latter in. The sound with vibration released through metal-on-metal connection is slightly tighter and more focused than with the whole spike-screw effectively insulated from the socket by coverings of Teflon tape all to my ear.
Again my sincere apologies, Rick_m.

Hey, no problem, I just couldn't figure "where you were coming from" as the younger folks say... Actually maybe now it's the older folks. Anyway I'm almost certain that I've heard it somewhere!
Vibrations and boundaries can be a real bane, especially if the speakers are fairly close to you. If I'm using small boxish speakers of any nature even for computer speakers I usually ugly them up with some rubbery weather stripping on the edges of the front panel to absorb HF energy where the 2pi space ends. And like you, at the outer tweeter boundary if it has a negative step.
Rounded surfaces and corners are more forgiving...
Rick
