Re: RAAL Tweeters - Why so low from the ground?
Mapleshade.....was looking at those myself, but a little steep for my pocket book.
Database, I had a similar experience with another product that follows the same principles as the platforms/footers. Small brass points placed between my Sierra-2's and the metal stands. They are designed to allow the vibrational energy from the speakers, or any component placed on them, to flow from the equipment and, ultimately, to ground plane. By removing this from the speakers it has, in my system, done much the same as what you describe. Efficiency & dynamics have exploded, etc., etc. I do not need to turn the volume up as high now, but it sounds so good I can't help but crank it.
Another recent tweak I did which has yielded very nice benefits was changing the crossover (low pass) filter settings for my Rythmik sub. My Halo P5 pre has built-in hi & low pass analog filters. They are both sloped at 12db/octave. I set the low pass to bypass so the sub gets the full range signal, and switched the filter setting on the Rythmik to 80Hz/24db, so double the rolloff slope for anything over 80Hz to it. This has tightened up and added definition to the bass that was not there. There are times when the sound is so startling that I have literally jumped in my seat!
Anyway, Database, Glad you are enjoying your system. I am at a point with mine that I have to nit-pick to find anything I want to "improve", which is not easy.
