Crossover Settings

[miata57]

Hi

I am hoping someone can help me with an issue I don't really understand.  I am using the Basx PT-1 preamplifier.

I dont understand why the crossover on this unit is at 90 Hz.  My floorstanding speakers go down to 38hz and so I am using the subwoofer's crossover at 60hz and volume but for some reason the bass is very weak.  I want to try the PT-1's crossover option but 90 Hz seems too high

I hope that made sense.

Thanks
Howie

I don’t know if anyone here can tell you why, other than for the BasX line, they chose a fixed crossover, and thought 90Hz would work for most of the speakers people would pair with these. For a processor, where the THX recommended crossover is 80Hz, 90 isn’t that far off, but I’d agree for a stereo preamp, 90Hz seems high. Unfortunately I don’t think there’s much you can do about it.
