Crutchfield Customer Review (What's this?)
The Thiel outrigger for the Thiel 3.7 speaker adds physical stability, better sound, and a more substantial look to the speaker. It makes it look like the Rock-of-Gibraltar instead of the Leaning-Tower-of-Pizza. The spike system that comes with the speaker is more than adequate, but if you have a thick carpet and a wood beam supported wood floor, as I do stability comes it to question. The outriggers answer that question with greater stability. Better sound comes from a more stable platform that allows less speaker movement. The outriggers give the speaker a more substantial and balanced look. The combination of the black outriggers with the chrome spike covers complements the design of the speaker and makes better looking. The spikes are expensive, but when you compare it to a damages speaker that some one accidently knock over and damaged it's well worth the cost.
Pros: Better stability, better sound, better looks
