Haven't used those exact ones but have used a lot of similar type tweaks on two different sets of speakers now. With Synergistic I have a long history of using a lot of their stuff and after years of experience it is kind of like yeah, go for it. Like recently their Purple Fuse everyone says is at least as good as QSA but costs less. So the value will be there, is pretty much a given.
Crossover Transducer, Loud Speaker Purifiers do they work? Have you used them?
Synergistic Research XOT Carbon - Crossover Transducer - very effective, big improvement!
Do these things really work? Have any f you used these products or something similar. Curious and willing to give it try but would like an endorsement and an honest opinion.
I do believe cables contribute as well as vibration control not a naysayer.
