KEF LS50 Meta

My local dealer has offered to let me demo them at home for a couple days when they get them next week. If it happens I'll post thoughts here.

Our new monitors are in a class by themselvelves nonene has ever produced a cabinet like this think 30k to 50k sound for 3500 when uzed with a good subbwoofer

You will be hearing ing our setups at axponna when the shows start again our sub monitor Package is goiing after Wilson and magico for 15k with bass down to 10 hz and tuneable to match the room size

Our monitors are totally unique in terms of clarity and imaging state of the art the enclosure does not vibrate or resonante at all the material is50 trimes more inert than mdf or aluminium total game changer

I curious about these and what sensitivity they will have. They sound interesting.

However, isn't cabinet resonance different from backwave energy? Sounds like the meta material in the KEF is designed to absorb backwave energy resulting in a more open, detailed sound. I guess cabinet resonance and backwave energy can manifest in similar ways (i.e. smeared detail and loss of texture), but even an anti-resonant cabinet has to deal with backwave pressure and secondary energy leaking back out of the driver. I'm certainly not a designer or engineer, just thinking about this from a layman's perspective. Sounds like KEF may be onto something that is dealing with both by having the meta materia and a rigid cabinet.

@kenjit ,

"I dont know where you read that it absorbs most of the backwave. It does not. The absorber is only used on the tweeter. Not the woofer."


Yes, a real pity since most of the backwave is caused by the woofer.

Still, even just an ’open backed’ tweeter sounds like a great idea if KEF have actually pulled off that trick in a mostly sealed box.

So maybe existing LS50 owners (and rival manufacturers) shouldn’t panic and would be better off waiting to see if customer feedback here matches Steve Guttenberg’s enthusiasm for the KEF LS50 Meta.

@abd1 could be the first of many out of the blocks before we get to see a direct head to head comparison between old and new.

Exciting stuff nevertheless.

If you ever go to a KEF Blade demo, one thing they so is to put quarter on edge and balance it on top of the speaker. Then they crank some tunes real loud. The quarter does not move and stays balanced on its edge. Love the Blade.

I got a demo today and ordered a pair.  Will shootout with my current ls50s when I get them.
