Audiofrog passive crossovers for the GB60/Gb15 combo. I picked these up pre owned to check out Andy's magic in a crossover. They're actually pretty damn good. Ran them with a Zapco Z-150.2ap. The tweeter attenuation has plenty of range. If you hate tuning and just want an easy solid front stage, these may be for you.
Will be double boxed.

$250, shipped to the continental US.
