I have these Sanyo AVS500 floor speakers from the 90's they sound great, they hit the deep lows of bass, i'm guessing down to 30hz, they are 12 inch woofers with dual ports on each speaker, and a 5 inch midrange and a 2 inch tweeter, i was wondering if anyone could come up with the actual specs for this speaker, ive always guessed they where 100w rms but i'm not sure and i would like to upgrade the crappy capacitors they used for a crossover to a real crossover but i need specs to do this, and how big of a improvement do u think the crossover will add to this setup
