Rel actually recommends nothing...I was using isolation platforms on my S510 subs left over from previous Rel subs...Watched the video John from Rel made about this subject...Removed the platforms,set them directly on the hardwoods and wambam...much much better deep controlled bass...I think they only suggest blue tack if you have wobbling from uneven floors.According to John the rels are designed and engineered with an exact distance from the floor to the passive driver,changing that distance causes many problems in what the sub will do......watch the video!
Has Anyone Here Tried The SVS Soundpath Feet On A Rel Sub?
Yes, Springs may be better. But unless I can fasten them to one of my subs, it won't work for my situation. Rel recommends the use of Blu-Tac under the OEM feet for isolation. But That won't work well in my situation either. The problem is that I have to move the right channel speakers because they are in the LR (UGH Why didn't I build my room before I got too old and the material too expensive SMH) . I'm considering Herbies Sliders for the mains. Yes, it may be a trade off. But that's life. Any suggestions besides getting rid of wife? Shes been with me for 46 yrs .
