Herbie's Fat Dot

I used them under large bookshelf speakers on wharfedale stands. HUGE difference in sound

Works as advertised.

4 big fat dots between speaker cabinet and plinth

I have some fairly heavy floor standing speakers (62lbs each), and Herbies recommended putting 4 big fat dots between the speaker cabinet and the plinth (and only hand tightening the bolts). I had to buy longer bolts to attach the plinth, but it was totally worth it. I thought they sounded good before (they’re $5k speakers), but the big fat dots definitely provided more clarity and ambiance to the music. My wife (who didn’t think she’d notice anything) was surprised at the difference. My speakers sit on a wood floor over a crawl space. I’m not sure whether the benefits would be as noticeable on a floor that doesn’t resonate as much. Best inexpensive tweak that I’ve found!
