It should make the soundbar almost as good as a bookshelf (eg. 1/4 cu ft) speaker, despite being a lot smaller
(eg. 1 quart internal volume). Soundbars are what is selling these days, so it was probably financially smart to go with it first. So I get that.
I recently asked my teenage son if he wanted help to build a speaker during his school vacation-
"Not unless the speaker can take music requests by talking to it?
No, I don't want a big wooden speaker like yours, Dad"
🤣

Very interesting. I suppose we'll eventually see this in all their powered speakers. In this related video they also discuss moving to current drive amps:
Things have really changed. New generation doesn't like what previous generation liked.
When I was a teenager, back in 80's, my dad had a pair of 15" big speakers and had a Ford V8 Galaxie.
All I wanted to have when I was an adult would be exactly that: the 15" speakers and the Ford V8.
But, at least, the KEF closed loop system is very interesting, as long as I don't have to talk to it 😊
Thanks for posting.
Ed,
Current drive will definitely help with their existing drivers. eg. MF of UniQ from KEF Reference 1 META
Meanwhile the velocity sensor and feedback will help with large excursions (ie. >>1mm).
So there will be an improvement when measuring with a log chirp/Farina exponential sine sweep.
But will this method (MFB for high excursion, current drive for low excursion) bring performance that will be able to improve, or just bring parity with other methods of reducing distortions?
And without a psychoacoustically validated metric, is it even relevant?
So far in the history of the mechanical transducer, what we have seen are incremental improvements that happen due to generational changes (ie. different people and times). Some drivers seem optimised for voltage drive
But current drive has been discussed for at least 15 years, and is only now starting to show up in commercial products (previously SGR, Focal).
