Gary, I recently revived an old thread about Tangent speakers and noticed that you had quite a bit of info on the brand. Do you happen to know if the ORIGINAL tangent company made the SPL-5 models that I recently brought back to life? There is very little information out there about this brand , no stock images , no catalog or brochure literature. nothing. They sound great, and I haven't even gone as far as re-capping the crossovers yet.
