JBL EON 712 fun

[roci_big_ear]

I have a couple of these for gigs with my band.

Here's the frequency response from the datasheet:

Not bad, not great. I guess optimized for SPL and pairing with a sub.

I played around with them and was shocked to find that the enclosure is tuned at 46 Hz. I was expecting around 80 Hz given the plot above.

What is very nice about the JBL DSP and app is that it allows fine grained EQ. After too many trial and error, I arrived at a fairly optimized setting for linear response:

(Measured 1 foot / ~30 cm away from the front grill)

I liked them before, but now - wow, it's basically flat down to 41 Hz. One of the main disadvantages is significant port noise below 50 Hz.

Power seems OK, bass is loud enough for me without clipping or shutdown.

Here are my settings, if you want to have powerful linear speakers:

1: 45 Hz, +9 dB, width 3
2: 85 Hz, -9 dB, width 4
3: 200 Hz, -2 dB, width 0.4
4: 45 Hz, +7 dB, width 3 (*)

* 4 is similar to 1. It's necessary for measuring flat in empty space, but for listening in the room close to walls, this band is to be turned off.

Thanks for this. A friend of mine rented some and they were surprisingly great sounding.
I would love to see these tested. I assume there is zero chance you will send one to @amirm.

Shhhh, stop telling people!! The word will get out and prices will skyrocket.
And those dynamics… so easy to get addicted to. There’s something about that sense of speed, coherence and near-explosive transient attack that once experienced in-home, is hard to give up.
The science points to it being mainly freq response and dispersion related so nearly any size/type spkr COULD potentially be capable of doing it.

It’s hard to accept it’s quite so simple when you just see the good, but slightly unremarkable response plot like your published one.
Then you hear and feel that percussive realism which seems unrestricted by volume control position and think can this really and readily be repeated by multiway smaller speakers for the same price range?
Never mind the quality madam, feel the width…

I use a pair of similar Yamahas for home theater sound

I got the Eon 610, so one generation earlier, and a step down from 612. I got a pair of subs to go with them, thinking that way I don’t 612 or 615, but after hearing them, I wished I had gone with 615. (Well, it would be 715 now). One of the 610’s and one of the subs blew after about three years, though, And I’m just a home user, no pro gig or anything. That part sucked.
