Is fitting a niche a requirement??
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.
Based on your metrics , Revel, Toppings, etc are sideshows.. so is our hobby. Perhaps not even worth discussing...
Who gives a shit about vintage JBL or current Sono sales....or even whether the CBT speaker is a "niche" product or not.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. (!!!)
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.
This is a good graphic.
I bought CBT24s at the end of last year. As evidence-based designs go, Keele puts these over the top by far. Yes, they could be considered aesthetically challenged, but my wife likes them. The engineering behind them convinced me to try and am thrilled I did. Here are the major attributes:
I got one of the last finished pairs during PE’s closeout (same price as the DIY kit). To get beyond a niche product, they need a smaller, turnkey model, but not sure how well they scale. Along with the larger listening spot, they do image well too. They do need a subwoofer for best effect, but apartment owners could get by without one.
- Broad listening sweet spot due to more uniform sound distribution
- Less room interaction (no major floor bounce response dip, much lower wall and ceiling reflections)
- No crossover avoids nasty phase, power loss and distortion issues
- Linear phase and time-aligned for the frequencies where human hearing is most sensitive
- Much less sensitive to placement in room
- Reasonably priced (readily outperform speakers that are 10 times the price)
It would be a shame if we lose what Keele has accomplished here. Would really hope JBL repackages a CBT for the consumer market as PE has reduced its offerings.
I think a planar-style transducer like a ribbon is best suited for a CBT, if more R&D could be put into the concept. Think a single ribbon transducer bent to form the CBT arc and have the shading as a continuous function decreasing smoothly towards the top, rather than having discrete -3dB or -6dB shading networks.
Thanks, saw this before I bought. I do eq these myself, so the FR graphs do not bother me.
