KlipschRP-600M Bookshelf Speakers (Pair) (Walnut)

First, I ordered on a Thursday afternoon and they showed up at 0530 hrs so that was quick and no damage.Moving on, I admit I am not or thought I was not a fan of Klipsch as my only experience was some years ago when I was demoing bookshelves and they seemed harsh and instantly fatiguing. So for many years I wrote them off.I saw these on sale and then starting research on this model. I was surprised to find real reviews from sites I regarded as well informed. I stay away from equipment reviews that just say, “good sound” or “I don’t like” without details or some sort of explanation.So, have had them running for about 15 hrs total. After one hour the bass tightened up which is expected and after about 12 the highs slightly warmed which I wasn’t expecting as I was biased against the horn tweeter plus the tweeter being titanium which in my experience has been harsh. But the soft horn definitely adsorbs the harshness and leaves detail.Until Friday the bookshelf I was using was my KEF Q300’s, I love these due to the punchy bass but also a bright speaker and need a warm to neutral amp. My amps have been neutral, nad 356bee, nad 704v2 and now the cardinal sin of hifi, two Fosi Za3 amps set up in mono, I swear I love these amps, another skeptical purchase I’m glad I made.The RP600m’s have that punch in the bass I love, not that too deep sound but you actually feel each part of the drum kit cleanly . I have them paired with a REL TX7 sub wired on high frequency to the amp via the speaker terminals which is unique with Rel and I can tell you this match up is perfect.Soundstage is there but not imaged like Kefs. More of a wall of sound so detailed yes but again KEF is known for precision imaging. Vocals especially male are what stands out. I listen to everything but hip hop and rap and country.Testing was done with blusound node streaming tidal to the two za3’s with stock op amps ( had Burson v7 classic in at first but a little harsh with both speaker sets)Details are abundant, some slight 3d but not much but that’s ok as these have a bit of a live sound which is definitely different but enjoyable on many tracks.Test songs : flight of the cosmic hippo, bela fleck.Jah Spirit, Billy Cobman. Heart of God, Zach Williams. Heart of the Sunrise, Yes (Steve Wilson mix). Little on up (acoustic live) Nils Lofgren.And a few versions of Holst planets.So I mixed it up, acoustic guitars sound so live. Jazz is mind blowing, bass guitar is heard like it should be and cymbals are airy.For $340 bucks you just can’t go wrong. And this is the first time I bought speaker without hearing. I have a set of Martin Logan’s I gave to my son. 1200 a pair and I wound up never using them as I hated them. But these i can if I had to in one word describe them would be FUN.Amp choice will matter. A warmer amp or tube will probably make these sing. I’ll put some warmer op amps (muses02)in my class D fosi’s soon and see. Fun fun fun.

The Klipsch RP600M is a great bookshelf speaker for the money. The NEWest version (600 II) is also an excellent speaker. It is possible to make the Version1 RP-600M even better with the GR Research upgrade kit but you have to have some soldering and tinkering skills to add the upgrade kit along with a few hours of your time. In stock form, Do the V1 600M's sound like my Klipsch La Scalas? Not but it really is amazing how good these speakers sound. Home run speakers for a super low price! The bass can fill a room and the highs are outstanding. Since the rear port is rear facing so the best bass will be produced if you can place them 2 to 3 feet from the wall, behind them.

In my personal opinion this Klipsch RP-600M, has a wonderful sound. I payed some records, jazz, pop and rock, felt better on Jazz. I compare to a Klipsch R-60M, for me the 600 sound better, bass is ‘punchy” a mid volume and treble. I’m very excited with my new pair speakers. I know these are old design and may be to be discontinued. So hurry, if you can reach and buy at the affordable price so far…, don’t waste time while last! Very impressive the mix of sound; brass, piano, guitars, sax the percussion. The 60M sound very impressive too, but the response between each one’s are noticeably different. So I’ll try my entire collection and digital music.Highly recommended.Don’t disappoint my taste for good sound of music.

High quality bookshelf speakers. When put on pedestals, with added Klipsch sub and powered by a Yamaha amp with low THD I was knocked out by how clear yet loud these bookshelf speakers are. I had considered getting tower speakers but judging by my current results I prefer these for sure. I can recommend for a higher end system.

Excellent full range speaker!!

Overall: The sound quality of these speakers is quite good and they are an excellent bargain at the price I bought them at ($377 for both, pre-tax). The hype are these speakers is mostly real, but there are some things to be mindful of before purchasing (such as, what sort of system you are connecting them to). I found that the general overall sound was very very good and I am super glad I bought these.Frequency Response: These speakers are widely accepted to be quite bright, with some critics saying they are a bit too bright and fatiguing to listen to for long periods of time. My experience with them is consistent with these reviewers, that they are brighter than average and I do hear that the highs are a bit louder than the mid/high-mid range. During the initial part of the break-in period, I noticed that some female and higher male vocals sort of dip behind the rest of the music in "busier" songs. After a bit of breaking in, this becomes much less of a problem (not sure if the crossover between the tweeter changes as the breaking-in period goes on?). I was using a Denon PMA-600NE as my amplifier, which is pretty neutral/slightly warm; I tend to think this amp is a great pairing for these speakers as it rounds off a bit of the highs. I could see a brighter amp paired with these speakers as not being a great pair, causing too much listener fatigue. I found that a natural way to mitigate some of the brightness if the highs are too intense is to simply leave the front dust/speaker cover on the speakers. The manufacturer claims a frequency response of 45hZ to 25 kHz. While there's not an easy way for me to confirm the high end of that range, I ran some sine waves through my DAW to the speakers to confirm that they do in fact reach the low end of the range. I was able to get to about 44 Hz before noticing a large drop off in bass response; I was able to technically hear down to about 36 Hz, but the noise was very faint (you'll need a larger cone to get better results there). I will generally say that below about 120 Hz or so, the speaker overall does seem to roll off noticeably when listening on axis, so I would recommend supplementing with a subwoofer.Dynamics: Excellent; very snappy and lively. The percussion transients really hit you and, coupled with the right system, you can go from very detailed low level sounds to loud sounds very quickly and seamlessly. No complaints at all here.Other Comments: Off-axis listening is something I plan to try a bit more once I get settled into my new apartment. Generally, it's not bad, though the highs pull in a bit and the bass tends to dominate more due to the sub ports that fire out the back of the speaker. With bass-heavy tracks (most notably house music), the bass does take on some strange dynamics occasionally when listening way off axis, say perpendicular to the speakers. Adding a pillow or maybe some foam behind the ports on the back of the speakers should mitigate this issue.About my system: As noted, I am using a Denon PMA-600NE for an amplifier. I'm using a Fluance DB10 subwoofer with a BlueRigger RCA cable; my speaker cables are Blue Jeans 14AWG that are split for bi-wiring. To test out vinyl, I used the Fluance RT85.
