I'm trying to get more punch or kick out of a 2245. The system that I had before my 4345 clones had dual 15" 2226 drivers. It had some serious kick.

My amp is a RAMSA WP9440 with 350 watts, I'm thinking I should try a bigger amp first? Maybe 6-700 watts?

Would a 2240 or 2242 be a direct replacement for the 2245 without changing the tuning? I'm not sure if I really need much below 50Hz, I just listen to 70s music, no home theatre.
