KEF LS50 Meta

They are the smallest and least expensive model in the meta line. So yes the laws of physics apply and there are limits.

Bass extension is not full range accordingly. Adding a powered sub addresses that easily. Still, don’t plan to go much above 90db spl or so even in a modest size room.

But they are top performers within those limits. If you need more then you move up the line to larger models for greater cost.

John Atkinson sure likes the speaker; it’s his reference.

Of course British audiophiles, with their typically small listening rooms, are willing to forgo deep bass altogether. 50Hz? That’s mid-bass. The bottom note on a 4-string bass (the E string played "open") is located at 41Hz. Any loudspeaker that cannot reproduce 41Hz at full volume is imo not a hi-fi loudspeaker. By the way, the lowest note on a pipe organ (the bottom bass pedal) is located at 16Hz.

The LS50 has a 5.25" diameter "woofer". I have a pair of speakers which use the 5" KEF B110 as a midrange driver, which is what it’s good for. A 5.25" "woofer"? Surely you jest! IMO the LS50 is a midrange/tweeter satellite in search of a woofer. I recommend a Rythmik Audio sub, which reaches into the teens. The combo should make a killer full-range loudspeaker!

Despite their flaws, a really good speaker from a price / performance perspective. Buy a pair from Crutchfield. 90 day money back guarantee.

Thank you everyone for your input, it’s been very helpful. I have a line on a pair for about $400 and I’m thinking of just going ahead and making the purchase assuming everything looks OK.

For that price, run don’t walk!  But I agree with bdp24…they need a sub. I like REL but Rhyrhmix come highly recommended. Beware used subwoofers…they lead hard lives, and amp failure is common.
