I'm not familiar with the SP Techs... but I've owned C2's and currently own C4's, both of which are respectable speakers. Probably can't go wrong with the C1's, as long as you've got decent amplification and can live with pulling them approx. 4 to 5 feet off the front wall, as they do best when they have room to breath.
SP Tech Timepiece 3.0-Dynaudio C1 comparison?
Anyone fortunate enough to compare these two speakers? If so would like to hear your opinion.
