I am a bass junkie and just purchased a pair of Cerwin Vega CLSC-215 Dual 15” 3-Way Tower Speakers which can each handle 500 watts of power, my certer speaker is a 200W Cerwin model and my rears are 100w Sonys. I have a pioneer DS1 Reciever puts out a max of 500w and does posess power amp inputs for the main, center and rear channels. I need to adaquately power my system. I want max power potential where do I turn next? I am more concearned that my bass can be heard in the next county then with the overall acuistics. Please help? I find the pre-amp, power amp, crossover converation confusing at best.
