Do any of the test disks provide an objective means to set a subwoofer crossover frequency, perhaps some ramping frequency tone that passes throught the crossover zone? I have tried a number of different musical sources and have had difficulty detecting the effect of the crossover settings with my untrained ear. I beleive that I have things set up correctly: small speakers all around, sub on (I do hear it working), and the sub's crossover turned up, out of the way, so the 1050's can do the job.
