Unless you're spending thousands of dollars, you're not going to come anywhere near 500 watts. It would be impossible to listen to 500 watts through CVs in a home setting even if you did have 500 true watts.
That spec is the theoretical maximum wattage input that they can handle. Its not an output. Speakers don't have watts.
alright thanx i have the cerwin vega cls dual 15 inch speakers and does it make a noticeable difference to go with thicker speaker wires.the store told me 16 gauge would be good enough but ive also got advice to go with as big as 4 gauge.
I'd like to read your impressions of the CLS-215? What other equipment are you using them with? What kind of music do you listen to? Do you use them for Home Theater?
