[enrique]

Hope nobody mines this topic,i would like to know proper crossover on my speakers.My mains frg. resp. 40-40hz,90 db(1w,1m),crossover (24db oct)700/3000hz.Center 89db,43-40hz,crossover(24db oct)600/3000hz.Surrounds 50-35hz,88db,crossover(24db oct)3000hz.Obviously i cant read this properly to know enough to properly set this.I presently have mains at 60,center 80,and surrounds to 80.My sub is a martin logan grotto also set to 80 in the rec.Dont know if maybe i should set the mains to 40 instead of 60.Would really appreciate any advice.All speakers are set to small.thanks

What really matters is the -3dB of the speakers overall. Setting the mains to 40 means you will be getting sound well below 40Hz, so I'd probably keep them at 60, but you are the one listening so how do they sound when set to 40? 80 Sounds fine for the center/surrounds.
