I have eight of these Parts Express spikes with threaded inserts, and I just won't be using them. I'll karma these, but winner will pay shipping as they are a little heavy, and will be sent in a small box.
Say "Spike It" to be in, and I'll draw the winner Sunday night.
Speaker Cabinet 1/2" Super Toe Spike Set 4 Pcs.
By rigidly coupling a loudspeaker enclosure to a floor by means of a spiking system, it is possible to dramatically improve clarity, stereo imaging and tighten up the bass response. This is particularly effective on flimsy flooring and thick carpet. Includes 4 toes, 4 threaded inserts and 4 jamnuts. Requires 1/2" hole and 10 mm allen wrench for installation. Dimensions: • Spike: 3/4" L x 5/16" dia. • Thread on spike: 1-3/8" L x 3/8" dia. • Insert: 1" L x 1/2" dia.
