LS50 META VS LS50 DRIVER

The cabinet is internally braced and ported at the rear. The original LS50, similar to most modern speakers, was only able to absorb 60% of the unwanted sound from the rear of the driver.Īpparently, this is the very first application of MAT in a speaker system. KEF describes this as “A Highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the Driver, eliminating the resulting distortion and providing purer, more natural sound”.

LS50 META VS LS50 DRIVER

What has changed and what appears to have made all the difference is the introduction of a material that KEF term Metamaterial and using Metamaterial Absorption Technology (MAT) they worked with the inventors to turn it into a disc shaped material that has been bonded directly to the rear of the Uni-Q driver to reduce rearward driver distortion. The drive unit is similar but not identical in that it now uses the latest generation 12 Uni-Q Driver whereas the original was Generation 11, so no big change there either. Technology – Where and how have KEF made improvements to what was already an excellent speaker and if it wasn’t broken why did the decide to fix it? Well, the enclosure is the same size and shape and largely made of the same materials. So, the questions here are, if you already own a pair of the original LS50 should you upgrade to the LS50 Meta and if you are looking for a very good pair of stand mount / bookshelf speakers should the Meta be on your shortlist? Matching stands are available for around £399. After 8 years they have introduced what is essentially a Mk II version called the LS50 Meta and with a price increase to £999 (at the time of writing).

Introduction – KEF launched the LS50 in 2012 and at £799 it sold like hot cakes, and deservedly so, it was a great little speaker bettering much of the competition at or above its price point. BOB’s Review Series - No 07 – KEF LS50 Meta Bookshelf Speakers
