I finally started to build my new-old project - 4 pi pro-like using Beyma 15M300, JBL 2426h & Eminence H290. I've two questions:

I saw that you've developed recently new crossovers, I'd like to ask if it fits also to my configuration - or I better stay with the old-one.

Is there any benefits (audiophile point of view) to add Deltas in mid-horns to this configuration ?

Could you resend me plans for this configuration please ?

Thank you in advance, Vlad.
