Shouldn’t we be looking more at PA speakers?

[ChrisG]

Were you listening to a single or a pair? I’ve heard that column speakers playing stereo can be pretty phasey.

Single.

Different EQ modes give different results, of course, but I don't think anyone could say the HF response looks good.

Hmm, ok…I have one set up in my listening room right now, I don’t really hear any issues in the FR. Maybe I’ll fire up REW and take a few measurements.

There’s a subculture of people who use cinema or PA speakers at home.* The problem for most of us is they’re mostly big and ugly.

*I guess I’m in it, given the 4 JBL CBT surrounds in our family room!

Can you share photos of those JBL surrounds? How do you like them? Always wondered about those.

Well, I took a couple of measurements of my Evolve 50 from about 5’ away and 5’ from the floor. On-axis and 45 deg off-axis:

Pretty impressive dispersion I think…the elevated treble also makes sense for a speaker designed to project sound over a long distance. I’m sure I could probably eq this thing pretty flat just with it’s onboard tone controls.

This is what the manual shows for presets. Isn’t that the goal? Good dispersion and then eq to taste?

Very impressive dispersion I think! I invented similar acoustic lenses several years ago, but never even tried to make them.

I wonder what the minimum listening distance is on above……

 

[norman bates]

I’ve wanted to make a mttm with morel cat378 and eminence b102, mainly for 15’ mlp (main listening position).

KEF LS50 (David) Versus JBL 4722 Cinema (Goliath) Speaker Comparison with Binaural Recordings

Here are two extreme opposite loudspeakers when it comes to sensitivity, size, directivity, topology and looks. Does the big speaker sound perceptually larger than the smaller speaker? Do the speakers sound the same if eq’d the same and level matched? Does the LS50 sound perceptually bigger when ...

I remember seeing this a while back but somehow just remembered. Thoughts?

 

[Flaesh]

Thoughts?

I have a habit of listening to “less room.” Although my speakers (SEOS24+15") are smaller than 4722.
Dynamic capabilities (which some scoff at) are also sometimes used

mttm

I don't know how (for ears))) the two tweeters will interfere.

I wonder what the minimum listening distance is on above

For "normal" 2ways crossed below 1k about ten feet or more is ok IME.

With the orange and red amps it should look great and deserves a quality paint job! Or vinyl-wrap must be very careful.

Famous system based on JBL 4675C (whith custom IB subs)
