I can't help thinking there would be a huge delay between drivers at the listening spot. Seems like this would result in a very unfocused imaging.

It's an interesting perspective on the definition of "sideshow." I view very expensive commercial speaker designs as a "sideshow." And I wouldn't call "DIY hobbyist" even a market..per se. That said, I have seen some DIY-hobbyist speaker projects that are complete..."sideshows." :)

Luckily, these Don Keele efforts don't fall into either category.

The easiest metric to normalize a definition for "niche" would be units sold.

As a figure of relative merit, the original JBL L100 sold 125,000 pairs in its original run. I don't know if any modern high end speaker comes even close to that.

At the other end of the spectrum, Sonos in 2018 registered 19 million speakers in 6.9 million households, worldwide. (!!!)

HI

Based on your metrics , Revel, Toppings, etc are sideshows.. so is our hobby. Perhaps not even worth discussing...

Eccentric, small-group hobbies can be fun to discuss! That's what makes them "hobbies".

Once something ceases to be useful, it can become collectible. ;)

How about the ASR niche of people concerned with sound and value? I'd like speakers that fill a room reasonably well with clarity more than give perfect sound in one small area. There are also pro speakers with this cbt design for much less money, made for churches, gyms, and the like. Just gotta get a used crown amp for the 100v system. Or am I best off with a dj style pa for that?

Who gives a shit about vintage JBL or current Sono sales....or even whether the CBT speaker is a "niche" product or not.
The CBT project is an interesting approach and design, regardless.

These appear to be similar technology. Are those from Dayton developed further?

I also wonder does the sound level staying the same over such a wide level or nearly so effect stereo imaging?

And how do these score on a spin-o-rama test?

And Meyer and others have been making large line arrays for use in big concert venues for a few years.

As I understand it, the main innovation that makes the Parts Express CBTs different from most of the live sound ones is that they are ground-plane CBTs. This is a variation intended for floor placement and eliminating floor bounce. The authoritative overview is probably Don's own website here.

Saw and heard these at the PE booth at Axpona a few years ago, sound and imaging was very good. Would love to hear these set up in a room with and without a sub. I read up on Don Keele and find him to be quite genuine.
