devialet uses driver moving mass compensation by aligning them vice versa - gives a more silent enclosure less working under demand
In think freedomnis decsribing the push-push arrangement of drivers so that one can take advantage of the active reactin force cancelation:

give it all or nearly all from get go at supposedly low volumes, but as you up the volume into last 3-5 notches, it all falls apart
The KEF LS60 has a similar DSP/high excursion woofer system and as volume increases a sliding low-pass decreases the bass extention as volume increases to first allow it to work, and keep distortion down.

Car audio to a T. 😉They may have bass quantity, but the ones i heard were not very well defined.
They do it with extremely long throw drivers, huge power amplificatio, and a whole lotta EQ.

For sure. It is advanced proprietary design. I have some doubts, about certain claims though. For example big high end PA speakers, talking about 21"s with paper cones, do withstand well over 1000N generated by the voice coil. So bragging about how impossible is it to make a cone with better proportions withstanding just ~300N can only impress consumer class of people. Not to put down the product at all, but they must overdo it a bit for the marketing.The woofers employed in these Devialets are no joke.

Never edit a quote. And if, mention what and why... good practise...

21s are proper subs. Four of them in sealed Q.5 boxes with a genuine 3kW amp for each driver make a lovely sound!For example big high end PA speakers, talking about 21"s with paper cones, do withstand well over 1000N generated by the voice coil.
Absolutely, this is an extract from their Devialet white paper that has some semblance of technical specification IMO. The section about amplification just rolls my eyes a bit. Uhm, "Class A Magic Wire"? 🙂Not to put down the product at all, but they must overdo it a bit for the marketing.

In comparison, KEF LS50's whitepaper is more informative. DIYers can at least learn about cabinet construction or damping from that.
