i just ordered a pair of samson s7hd's. i really dont wanna shell out $500+ for a new amp until maybe next year. so my question is just that is 230 watts enough? my current tower amp is 4ch that will push 230 wattsx2 if bridged. the s7hd's are 250 watts rms. i know they can handle and really need more but will they sound punie with 20 watts less than rms? the towers are the only thing running off of this amp. i also have a ws420 so i can tune it if the lower watts affect one aspect over another.
