Best Isolation Device for Speakers?

You need to call the boys at Starsound about the use of Sistrum with your speakers..You should be able to position the triangle of the Sistrum in a way that will not interfere with the driver on the bottom..They will help a lot. Even the use of Audiopoints 1.5 in will be large..Tom

Sir I beg to differ. In your proposal there is no provision for resonant energy to leave. The resonance will come out the front the back the sides. You will have a 360 degree resonant pattern to augment the music..Tom

I recently left the confines of working for a retailer that sold Thiel speakers..I know from experience the Thiel's will improve as much as any speaker I have ever tried either the Audiopoints or the Sistrum platforms on. It is because of the Thiel cabinet mass and density that the improvement will be so large..It is imperative to match the proper size Audiopoint to the respective Thiel product..Again because of their mass and the great amount of excess energy that these very dense cabinets do store..Sistrum Sp101 platforms are what I personally use under my still almost Dunlavy SCIV's..Tom

Twl is correct. I too have measured an increase in spl when using the Sistrum of about 1.5 to 2db.. This was measured in the retail showroom with an Audiocontrol RTA..Oh and these are not isolation devices and if you were to try to dampen or isolate the Thiels they would only gain in bloat and blurr.Tom

Charlie you are correct. The cabinet is in motion and stores energy and that counteracts the motion of the drivers we only wish to hear. That is why I use the Sistrum stands under all my components as well as speakers. The designer makes claims that I agree with. That their products provide geometry and materials which expedite an speed to ground, resonant energy.. They made a huge performance gain in my system..Tom

You have lost efficiency by hanging the speaker in air.The natural tendency is for the cone to move back and forth. The back emf is swinging the speaker.. The front force of the cone is being cancelled by the back emf. Who wants that? An athlete can get off the line faster and with more stability if they have spiked shoes. Cabinet, no matter how dense will store energy.In fact the more dense the cabinet the more resonant noise it can hold.So it is even more important to direct couple these type of massive enclosures. The noise has to be given a way out or it will pollute the music..Tom

Sir you are mistaken. The back and forth motion of a 100lb speaker on a carpeted floor while reproducing music is greater than the total excursion of the tweeter in that very same speaker. So much for proper phase response and time alignment..And sound is like fluid. Unwanted energy needs an exit point..Tom

Yep....Tom
