It took me a minute to get used to the horns as this is the first set of speaker that I owned with horns. The more I listen to them, the more I appreciate them. They are Big and heavy, but beautiful. I have owned many different brands of speakers and I'm now sort of collecting old beauties like this. This is the best I have owned. I have read other review saying the bass is weak and I can't disagree more. I run them with an old Denon PMA-700V. The Bass is almost overpowering but Perfect. I do need to almost turn the Bass control to off when playing them loud. When sitting in the center of them, they are spacious and you can distinguish every instrument clearly. I can crank it up to levels that actually move my clothing and they just stay crustal clear. I have Polk, Infinity Delta 40's, KEF, RT, Boston, M&K and I love them all in some fashion, but none can do what these do.

Possibly a touch Bass Heavy.

I picked up these speakers used on eBay for $600 and have used them almost as much as the Cornwall’s I have also. So I am lucky I have a direct comparison. I use vinyl almost exclusively through a Benz Micro Glider MC Cart and Audio Research amps. I have to say that the KLF20s are a rock solid performer, open rich and warm. These units need carefully placing and ridged spiking. For all the listening time and enjoyment, I find myself drifting back to the Cornwall’s. If I didn’ Own the Cornwall’s, I could quite happily live with the KLFs.

The only lacking features really is deep bass, but then again I am spoilt.

Legend in sound

Best of the best speaker in the world and very good sound with Marantz amp

Funny I'm writing this review so late after these wonderful speakers came out. I must say after owning so many other speakers( JBL SVA2100, B&W, Mirage, Martin Logan and countless others) This is by far my favorite pair, and I may never get rid of them! They truly sound like you are listening to live music with every CD, or bluray disc. I couldn't be happier, if you can find a pair do yourself a favor and pick them up! I am in the process of getting either a KRELL (Old school) or Pass Labs to mate with these speakers to make them really shine!!! Klipsch for life!!!

Really a legend speaker best ever made!!

Love these! Like other high quality loudspeakers of value, the 100db+ sensitivity results in lower distortion and lower power requirements. Compare for yourself. Every 3db increase in sensitivity cuts a speaker's power requirement in half. That implies that driving 100db speakers with 40 watts (e.g., KLF 20) is like driving 91db speakers with 320 watts (e.g., Energy 8). You can easily hear the quality in the KLF 20's. belkan

Picked this pair of speakers up along with a Polkaudio 200W subwoofer and a nice Yamaha (can't remember the model #) reciever for (don't hate me!) $600.00!! All of it in mint condition. I'd been using a pair of 6.5" Alesis MK2 studio monitors for my home studio and decided to see how the KLF 20's would sound in their place. This was 3 months ago and the KLF 20's are still there and the Alesis's have long since been sold. These speakers sound utterly amazing! The frequency responce is about as flat as I've ever heard, rivaling even my bandmate's pair of $1500.00 M Audio DSM2's! About the only complaint I have is their weight. They seem like they weigh a freakin' TON! Almost as much as my Randall Warhead 4X12 speaker cabinets! Anyway, Can't say enough about these speakers! They REALLY rock!!

Great amount of bass, no subwoofer needed, unless you are a true bass head. Very accurate speakers with a huge soundstage.

None so far, just a bit heavy.

These speakers are great overall speakers, I have been shopping around for years to find a pair of these in pristine condition. They are beautiful, and are way ahead of their time. You will not be able to find a pair of speakers within this price range that will even be able to touch these. These speakers pound on home theater, and are very accurate when listening to music.

Presence is the best. Wonderful speaker even after 5 years...

Manufacturing issue in this model year. Back of speaker was attached with poor quality glue. This is a known issue by the manufacturer. This can be fixed by them or the buyer if you wish to take the speaker apart and use good glue, I used liquid nails.

Bottom line: This is one of the finest speakers you can buy. There are SO MANY SUBJECTIVE FACTORS that are reflected in many of the reviews posted here. Issues such as cable, bi-amping, model of receiver, capacitors used in the crossover circuitry, and phase of the moon are subtleties that you may or may not hear. My advice: Listen to this speaker, listen to a dozen others and then come back and listen again. Klipsch makes speakers with horns. Horns push the sound up front. You may not like this or you may love it just like the many ten's of others that have reported here. My opinion is that it is still the finest speaker for music in this price range. I really haven't listened to speakers costing thousands more so I can't make a fair comparison there. But, I have been listening to speakers for 30+ years and love this sound. The type of room you have and the placement of the speakers will make way more difference in the sound than your wire, receiver, capacitors, CD player brand, bi-amping and moon phase combined. Opposite surfaces should be different, ie: if the ceiling is reflective (smooth and hard) you need a soft floor surface (carpet). Some walls should have absorbing qualities. There needs to be sound absorbing material in your listening room (soft furniture, draperies) or your sound will be wacked, I promise! This review is as much of a testimony to the art and science of the Klipsch philosophy as it is to this particular speaker. And no, I don't work for them! Klipsch speakers have more 'presence' than any other speaker I have ever heard, period. So, if you can't find the KLF-20, listen to the other models - but only during a full moon (he,he).
