The Tangent speakers used the Audax bextrene 8" bass/mid. drivers These drivers were very inefficient(around 84db) and wouldn't handle much input(rated at 25 watts) but they were very musical with a punchy bass down to around 40-50hz. My memory of the Tangents is quite positive but that was a long time ago. The only way to determine how they hold up to more modern designs is to listen and compare.
