PQ1 Plinth Spike Kit

Installed these on my floorstanders and the bass tightened up noticeably—no more boominess in the corners. The threading was clean and they locked into the plinth without any wobble.

Wasn't sure these would make an audible difference but the low end tightened up noticeably once I got them threaded in. They screw in solid with no wobble, which is exactly what I wanted under the plinth.

The spikes threaded in perfectly and gave my speakers a much more stable footing on the carpet. Only gave four stars because the included wrench is a bit too small to get a good grip for tightening.
