The only feet you ever put on a subwoofer are spikes. Any vibration of the subwoofer in operation is distortion. Ideally only the cone is supposed to vibrate but in real life Newton usually wins out and the whole enclosure shakes and actually moves. I have seen subs walk across an unlevel floor! Subs have to be held firmly in place. The best subs now use what is called a balanced force design. They put identical drivers in opposite sides of an enclosure and run them in phase so the forces cancel out. As long as the enclosure is super stiff this is the best way to build a subwoofer. Magico, Kef and others are now using this design. But, it requires a second driver elevating the cost.
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 .
