Came out of a 210 TX cabinet of unknown age. Sounded fine and are fully functional. I just replaced them with eminences because I wanted greater power handling. I drove them with a GK 400RB with the master never above 50%. The 210 TX was rated at 175 watts at 4 ohms so that would make these 8 ohm drivers rated at 87.5 watts (?) each. When I took them out I was surprised how heavy they are - only slightly lighter than the eminences. And I didn't notice a big sound difference either.. ..but it's done and I'm switching to a higher powered amp. So I'd like $25 a piece for them and will throw in shipping to anyone in the contiguous 48 who buys them both. I'll consider other offers or trade offers for preamps (I'd add cash). Thanks for reading.
