JBL Hartsfield crossover

[Aquaplas]

I am looking into solutions for a crossover for the JBL Hartfield with a D150-4c and Flat backed black 375. Picked up a single unit but was missing the crossover.

My research shows the model crossover as a N-500H. I have also heard another crossover could be used.

Suggestions?

Thanks!

I use very simple first order crossovers with L-pads that work wonderfully. Bass horn runs flat out.
