"title": "5.0 out of 5 stars Reference standard reasonably-prices stand speaker.",
"body": "Love ‘em. The most amazing thing about these speakers is that, by design, they are both time and phase coherent. So what? Well, that means on a good recording, you can hear exactly where the vocalists and instruments are placed in three dimensions. You can even hear different voices within acquire and different instruments within an orchestra very well. They also nail the dynamics of percussion like nothing I’ve ever heard in this price range. I don’t consider Stereophile magazine to be the absolute reference, but I do put some credibility in their reviews. They include the speakers in the “restricted low frequency” section of their recommended components in “Class A,” and some of the reviewers use them as their reference speakers. That is saying a lot, considering that many of their recommended speakers cost more than the average new car today. I’ve used them with extremely good separate components by Audio Research and McIntosh, but you don’t have to have that quality of electronics for these to sound excellent. I use them with a pair of subwoofers, but I have turned the subwoofers almost all way down, and they still have extremely good bass although not at the lowest octaves. I think the mids and highs are amazing too, especially considering that they use metal drivers. I got really turned off on metal tweeters by a pair of B&W speakers I had, but these exhibit, none of the sizzle and ringing that those did. Further, I think they’re great for almost any genre of music, from Black Sabbath to Beethoven. I have since upgraded my speakers because I got an incredible deal on a pair of Evolutions, but from time to time I consider swapping these back in because there’s something about them I kinda still miss. That said, I’m not selling them. They literally are the types of components that I know I would regret if I ever got rid of them. Read more",

"title": "5.0 out of 5 stars Excellent speakers - typical \"audiophile\" BS in the reviews",
"body": "These are not party speakers, these are speakers for enjoying in small rooms at moderate levels. If you understand that, you will probably like them. It's obvious by the design, a 4\" woofer with a concentric tweeter, that they are not meant to move a ton of air. Distortion rises quickly when you crank the volume. You can mitigate this somewhat by integrating subwoofers, but it's still a limitation. With that in mind, you don't need a huge amp or a subwoofer to enjoy the LS50 Meta. With basic components and at reasonable levels you will get neutral tonality, low distortion, wide dispersion, large soundstage, and clear imaging. Hard to beat, just don't expect to drive them with a 40wpc amp. If you want sub-bass extension, they will benefit from integrating a subwoofer. Just like every other bookshelf speaker. Now look at the waveguide. It's a work of art. Read more",

"title": "5.0 out of 5 stars Clarity, Detail, and Imaging Nirvana",
"body": "I finally found some speakers that sound fabulous at around 70 db. No need to blast these, they deliver the goods on clarity, detail, and imaging at comfortable volume levels. However, they don't sound good at low volumes. I have never had speakers that exhibited zero cabinet resonance like these. I wouldn't use these in a large room, but for smaller rooms they are incredible. These speakers deliver quick, powerful dynamics while listening to challenging classical music. The only downsides are they can't project a big sound wave into large room, and although the bass they deliver is super high quality, it isn't very deep. Read more",

"title": "5.0 out of 5 stars 5 stars, but Wimpy cheap amps and budget equipment? Don't bother.",
"body": "I see a lot of reviews here saying they sound bad. It's simply not true, because then I see what they are running, and its a very low tier amp. Your \"200\" watt Emotiva BasX or similar class amp simply does not have the torque that these speakers need. I know, I own several Emotiva amps. I'm an audiophile, and have lots of gear, it's the hobby. I'm running these off comparably priced equipment, all of my gear is in the price wheelhouse of the Ls50. My amps are Orchard Audio class D GaN monoblocks with GaN power supplies. I run a Gustard X26 Pro dac, dual mono dacs, dual mono power supplies, excellent clocks. This speaker goes down to 3 ohms. Your cheap amp is likely begging for mercy at this impedance regardless of \"200 watts\". You need high quality. Give these high quality components and this speaker is AMAZING. I have 7 sets of speakers. All different types, Magnepans, CSS Audio, bunch of stuff. These speakers are worth every penny! But bear in mind their performance sits right where the price range is. These are not $10000 speakers for 1600. You get what you pay for. That said, in the 2K range, they are probablyunbeatable, for overall performance. Another caveat though is I have a pair of subs, near field, 3 feet off the ground, perfectly tuned with these speakers. You need a setup like this for perfect full range sound. If you're an audiophile, I recommend starting with these, make sure you have nice, NICE components to back them up, and a pair of subs when you can do it. I'm running 2 RSL Speedwoofer 10s. If you just buy these, you don't own subs, and your equipment is like $200 dac, no preamp, $500 amp, low level stuff, you're going to wonder what all the fuss is about and return them. Do them right, you may never shop for speakers ever again. Read more",
