I have SP-1's under my Von Schweikert DB-100's which are 200 lbs. each. I believe they are well worth the money for the improvements they create. Bass tightness, overall definition and increased dynamics are what I have heard. I lived with only one SP-1 for 6 weeks so I had the chance to hear the difference between my 2 speakers. In retrospect, it was a good opportunity to identify the SP-1 strengths. Your 100 pound speakers will anchor just fine on this platform. I think the SP-1 is quite inconspicuous visually. You can hardly see them under a speaker. An added plus is the platform raises the speaker a few inches to raise the midrange drivers closer to listening height. Get-em.
Sistrum Platforms under floor standing speakers
Has anybody tried using these platforms underneath any medium sized ( about 100 lbs ) floor standing speakers ? I understand what Sistrum is trying to accomplish, but I was just wondering about stablity while on the platform, sonic improvements..etc.....I am currently using ''their '' two inch Audiopoints to get my speakers off the floor and was wondering if spending the extra money would be worth my while on their platforms.
