What? You didn't caulk the horns
Just so you know my DE-250s were over a year old with at least 1000 hours on them before I mounted them to the H-290s. Prior to the 290s, they played through woodhorns which have a seductively musical but less focused sound than the Eminence.
I immediately loved the H-290s except for a noticeably "plastic" coloration. Maybe not plastic but certainly there was an artificial ringing that came with the extra focus that bothered me. The rope caulk eliminated it and took the 4Pis to a new level.
Those who know me are aware I'm not much for tweaks but I am death on vibration control. My crossover is mounted on 1/2" of EAR Isodamp (the blue stuff in the pic) glued to the cabinet bottom with EAR Microsorb (which is why there is wax paper under the board in the pic). The rope caulk is in the same cause and it, like the EAR products, works.
