no shure abt the crossover freq.. i set it to 100hz..
any recommendations?

Thanks for tips, Paskal!
Yah my onkyo receiver cannot set the crossover individually. I should probably go by that setting, cause my boston speakers frequency has a limit of 150hz-200hz.. hmm would it somehow underutilized my tower speaker since its output can be in lower hz?

Would it be better to get another receiver?
