Hello you wonderful people. I got some big *** speakers this week. I'm interested because the lower part seems to be a wave guide down to 250 Hertz maybe 100? There's not a ton of measurements online.
I can cut into or experiment however I'm looking for ideas.
My thoughts right now are maybe meh or syn for the lower mid section for make them full range? Looks like the standard from JBL is 250 hz high pass to these. I do have the crossovers that came with them which look really nice and complex.
Does anyone know if these high horns are constant directivity like the older JBL Cinema stuff that need that compensation EQ? For the high?
I'm also thinking about opening up the backs for open baffle.
I'm curious what kind of control the big *** lower wave guide might offer
Anyways any ideas on a good Way to go to make these into awesome home speakers.
I'm not a speaker engineer or designer or scientist

The 4 horns are midrange. If you look those up, you’ll see they are sitting on double woofers for bass.
The seller had those but I couldn't fit them in my van 😂
They were x2 15s and looked really nice

Yes, like DR. said. If you can you should go back and get them. Great drivers.
Continuing the multiple entry concept below 250Hz would probably show diminishing returns. Those waveguides would already be reaching their limits there. It's also into Schroeder territory and our hearing sensitivity is lower.
Therefore it may be a good idea if you can't find an alternative but I'd be trying to dial them in first as is, with placement and EQ.. see what you can accomplish.
Dear Cooper,
All the best.
- Get the pair of 2035s, as already mentioned by drjlo
- Use the following EQ settings as a starting point (2-way and 3-way included).
- Depending on your processor / brand, you may also want to read the DSC260 manual for converting the term 'Bandwidth' to Q-factor. Generally, Q-factor = centre freq / bandwidth, but there're other definitions. It is also useful for an understanding of the terms Bell, Hi12 etc. used by JBL.
All the best.

Made them ob, pulled out all the JBL crossover filters, switched the 2425hs CD for a pair of open back b&c de250. I don't have that DSP at the moment so I just have them actively crossed at 1.2khz and 250 hz right now. The woofers are wired series parallel approx 6ohm.

I have them pushed up in the corner which leaves about a foot to each wall and back corner.
Having the speakers in the corner works well for my space. From practical perspective that is I'm sure acoustically other locations would be ideal.
