I posted this once last week but I still can't make up my mind, sigh....I can't A/B them 'cause they're hard to get in holland. I recently bought a EBS TD650 And I'm thinking of a 410(70-18Khz,800w) 15H(50-3khz,400w) I'm not sure if these handle my low B nice, since they don't go lower as 50Hz. Or a 212(30-18Khz,400w) 210(70-18Khz,400w) I don't know if this will provide me enough clarity and transparity. What do you guys think??
