When it comes to physical technology, LS50 Wireless II takes its lead from KEF’s LS50 Meta passive loudspeakers. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology1 (MAT) is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural sound.
Q: When will these be available?
A: KEF is having supply issues, but for reasons that probably aren't interesting enough to describe in detail Best Buy's inventory system is exaggerating the problem. Keep checking back, the black color has been in and out of stock. I got mine through Best Buy a few months ago. If you don't want to wait they are available elsewhere; just be sure you check KEF's website and order from an authorized retailer or they'll void your warranty.
