I have the older polk 6 3/4 separates in the front stage and 5 1/4 Polk DX separates in the rear built on to a plate. Right now I have the fronts crossed over at 100Hz with a 6db slope. And the rears at 125Hz with a 12db slope. I was wondering is this is the way to go or should I be doing something differently. I have 2 12 inch Image Dynamic IDMAX subs crossed over at 70 hz 18 db slope. I crank my music pretty loud so I don't want to distort the mids. that is my reason for the kind of conservative crossover points. Should i lower the crossover points? Should I Change the Slopes 6,12,18,24 are my options. The separates are getting about 60 wrms. Thanks in advance.
