JBL EON 615 Repurpose

[Bathymeter]

So I have an EON 615 that's hard to find a repairer for, plus I want to try my hand at converting it to a usable passive speaker again myself.

I understand that's there's a lot of active magic happening in that huge cluster of circuit boards, but if I were to only use the drivers, is there anything I need other than a crossover and an amp? Will it sound trash if I build a 2nd order Riley @ 1.8kHz (recommended crossover) then power it with just a normal 200W amp?

Alternatively, how would I just make a subwoofer out of the LF driver? Do I just need a low-pass filter and an amp?

I am a complete n00b at this, so any help is appreciated.

Hello and welcome to the forum!

That's a pretty beefy speaker! My first thought would revolve around how easy it might be to remove all the electronics and seal up the cabinet. Provided that can be done, I really don't see any reason you couldn't turn it into a passive speaker. That said, using a book value crossover without baffle step compensation might not produce the best result, as it rarely does.

Couple questions:

• Whereabouts do you live? You might have someone around with measurement gear, which could be used to design an appropriate crossover for your application.
• Speaking of application, do you intend to just run one of these for parties and such, which sort of seems like maybe what it was intended for? Indoors or outside?
• Where are you getting the advice for an LR2 crossover @ 1,800 Hz? Was that on the product page and I just missed it?
• Do you already have an amp?
• Do you have a budget and a timeline?
