I've had double low Sistrum racks from Live Vibe for about 5 years and Sistrums under some speakers. Love the look and especially the sound. I have RTS couplers clamping each component to it's platform--great sound upgrade and it eliminates the possibility of tipping or knocking a component clean off the points. They even look like they belong on a Sistrum. Your can even put them in the middle between the speakers as long as they are a little behind the backs of them with NO sound penalties. Got a great deal on some used Sistrums and RT couplers--thanks Al J. You'll love what the Live Vibe stuff does for the sound!
