Review on Premium HiFi (IF03B) Speaker Isolation Spikes - Shockproof Stand Feet with Vibration Absorber - Enhanced Speaker Cone and Non-Slip Base Pad for Turntable, Amplifier, CD DAC, and Recorder (Black) by Tsuyoshi Tendencies

I needed to reconfigure my home theater and faced a dilemma: my center channel needs to sit on a pair of subwoofers. Not quite the way I want it, but it's a cosmic thing. These isolators work well to prevent the center channel from sliding over subwoofers. If you have speakers without feet, this is a great way to elevate them off the floor with hard floor pads or carpet spikes. Mine didn't look as good as the pictures. The copper tips were rusty and rough, and the box appears to have been renamed from something else. They're inexpensive and the quality shows, but they'll serve a purpose.
