Here we are in 2020 talking about Eosone RSF 600, and I'm seriously impressed by these short lived speakers from the mid 90's. Picked up a pair of RSF600 for my favorite price "free" about a month or so ago. Snagged an original tweeter on eBay since one front tweet was dented and now I'm good to go! These floorstanding speakers are very heavy duty, the MDF is thick and they're constructed extremely well. The bass is great and punchy, I could definitely get away with not running them off my Polk PSW10 subwoofer. The highs are not colored or crazy bright like my Polk floorstanding speakers. The mids are great and I'd say better than some speakers that I unfortunately spent big bucks on. Like what the heck is going on here? My vintage Denon and my other integrated amplifiers are all left flat with no bass or treble adjustment needed whatsoever with these speakers. Now I've moved them to my main listening area and they're currently hooked to my favorite seperate preamp and amplifier. What's so special about these Eosone? The sound field technology by Arnie Nudell. It has me excited to own them and to be able to experience their sound. There's now sound everywhere in the room, instead of just sound waves coming directly at me from a speaker or a monitor. The sound stage these speakers can create with the right equipment is spectacular. Meaning my small listening room sounds like I've added square footage, then added more speakers. I can hear separation of instruments and even at times I'm catching myself saying "whoa" to some of the detail in the high parts of a song I've listened to many times before. These speakers are worth more than what they were charging for them back in 1995. Not sure what happened or how many Eosone they made, but snag a set if possible. Mine are going nowhere and I'm going to recover the grills I like them so much.

Not really a weakness but holy cow they're seriously heavy. I don't think I'd call them attractive, or boast about their looks... but that's not really a weakness either. I'd say there's one cosmetic complaint. The top is a removable board, why? Your guess is as good as mine, possibly another speaker was going to rest on top of these floorstanding speakers down the road? This removable top, was covered in piano black veneer... That you guessed it chips off if the top ever accidentally comes off or a person were to drop it. One speaker I have has a massive chip in the piano black, from I'm guessing a single drop experienced over the last 25yrs they survived. I noticed other individuals selling Eosone also have chips in this removable top.

Purchased in 1999 and still part of my secondary music room. Superb design and performance have made this speaker sound just as good today as they did 20 years ago. Though purchased originally for movies and surround set up. Which they were great at. I have found that when I moved them to a room for primary music listening, they really excelled. Fantastic, when driven just in pure stereo mode, with a high powered amp. With a subwoofer thrown in, the sound just got better. Low production makes these hard to find, but if you can get a pair online that were taken care of. Go for it!

Best for low end driven music when a dedicated sub is used. But with acoustic, classical and bluegrass, the smaller woofers do just fine.

Wow, after nearly 23 years, I am still in awe of these speakers. They simply sound amazing, and in my opinion, sound better than all other speakers I have ever owned. They sound very smooth. You just want to keep listening to them. I simply love these. I plan to use these for 100% music now, and get a whole new set for my HT.

I cannot think of a single weakness. I just wish they had not stopped making them, or that I had bought the center, and surrounds and more surrounds. Sweet.

I bought these speakers off Ebay for $250. I needed speakers to listen to while I had my B&W 802s serviced, which took about three months longer than it should have. There was a little cosmetic damage which I was able to disguise. The speakers are three way with twin 8 in. woofers and in addition to the 4 inch midrange and titanium tweeters up front have midrange and tweeters in the back, rear firing, which I imagine are an attempt to improve imaging. I was immediately intrigued by the Eosones' flat frequency response. Not flat sound, but consistently level response from the lows through the highs. I guess all that means is that the bass and treble knobs on my McIntosh C712 preamp are both at 12 o'clock, not the 10 and 2 o'clock I've had to use to adjust the B&Ws, but I like to think its an indication of something deeper. I've always thought that Polk speakers' highs are a little colored, even if beautiful for most types of popular music. The highs here are lovely and have no color at all as far as I can tell. As far as imaging, these speakers do an absoloutely amazing job in the awkward spot I've had to use them in my little house. The only real fault I can find with them is a little bit of color at the very low end when listening to rock n' roll. Its not there when I listen to classical. Many people who listen to rock will actually prefer the color in the low end, my friends generally do. Its still very tight bass. The music is beautiful.
My $4000 B&Ws have returned from the shop, but they're not hooked up.
Other equipment I own for comparisons' sake include a McIntosh 275 power amp and Sony SACD player. Its a nice setup that definitely brings out the best of the Eosones, but the B&Ws, which are kick ass speakers that the experts love, had the same advantage, and I like the Eosones better.

Great bass in my opinion, exceptional sound clarity, driver in the back of the cabinet creates the illusion of a slight surround effect...keeps things nice and simple.

Might be a little boomy in some applications, but that can be controlled with a quality receiver/amp.

I'm 30 years old now, but I got these when I was 18. A friend of mine working at Best Buy told me I should come listen to them...I did, he got me his discount and that was that. I wanted the RSF 1000 model, but they were double the money, so I went with these. Well, 12 years later, these things have gone through countless moves, keg parties, etc. and they still sound incredible. I just upgraded my TV to a 56" DLP, got a PS3 for the Blue-Ray capability and next will be the audio system...but I got to thinking, there's no reason to replace my Eosone speakers. I was just searching the web to see whatever happened to them and came across this site. As far as the bass goes, I don't see why people are knocking them. I was a big car audio nut before I got my Mercedes (which needs no help in that department), so I appreciate clear bass response. That said, I have my RSF 600's in an 18'x26' room and I don't see (or hear) any need whatsoever for a separate subwoofer. They're currently powered by a 12 year old Harmon Kardon 50 watt per channel amp (very clean 50 watts) that I bought around the same time as the speakers, but I will be upgrading to something with HDMI and Satellite capability soon. Bottom line, I have the money to spend on speakers, but have no interest in doing so. I love these speakers!

Never needed it....these things have been through hell over the past twelve years and they still sound like they did when new.

Have also owned Cerwin Vega, Polk and Infinity speakers. Have a friend who works for Bang & Oluffsen and even he is impressed with these.

Nice crisp sound. Due to the fact these speakers don't produce alot of bass these speakers are ideal if you live in an apartment.

The bass, which can be greatly helped by a decent sub.

These were good speakers, especially if you got them when Best Buy was closing them out. When I first got them one of the speakers had a slight hiss to it. Best Buy exchanged it for another that worked great. As others have said, it does lack somewhat in the bass. However, I have a Velodyne sub to pick up where my 600's lack and it works very nicely. Strangely, the bass or lack of, was what originally appealed to me. When I got them I lived in an apartment, where a lot of bass would cause problems with my neighbors. Recently, I considered upgrading to a smaller satelite speakers. The satelites I've heard so far it would seem I'd have to spend about twice as much to get the same quality sound. I think I'll keep that 2 grand and put it toward an upgrade worthwhile.

I bought the 600's for $899 and a RSP912 for $350.I also added Polk rears & center. I auditioned many speakers including Klipsh,Infinity,Polks,Vandy's ect. My receiver of 17 years just took a crap. It was and still is a great receiver and will miss it dearly; however, it is time to upgrade. I have auditioned Denon 3200 & 5700, Yamaha 2095, HK, Rotel 965, Marantz 780, Nakamichi AV10 & some seperates. One thing I can say is that everyone has their own listening tastes. When listening to the receivers at the stores I realized their sound was being greatly influenced buy the pairing of different speakers and the enviroment. For those reviewers that give products a 1 or 2 I would say unless you bought a product and had problems with it and were not shown good customer service give it a 1 or 2 as this is the heigth of stupidity for any company to do. Otherwise give it a 3 thru 5 with the knowledge that maybe your equipment is not matched well. A cheap Amp and great speakers equals poor sound through great speakers. Instead of complaining about the speakers maybe you should be asking the people who enjoy theirs what components they have complimenting them. I for one am happy I bought the 600's. If I could get a great deal on the 1000's I would buy them. For any who are interested I am pushing them with 150 wpc by a Sansui G9000. Base is tight,mids are clean, highs are a tad bright.It sounds better with the sub not in the 180 phase out position. In this price range I refuse to give a five but will gladly give a 4. Try adding a second subwoofer. Its awsome. Its a tough audio world out their! Good listening.

Ouch! These have a very aggressive, brassy upper midrange. This combined with a boomy, ill-defined mid-bass. They do sound better than the other speakers at Best Buy, but that isn't saying much. I suppose non-critical listeners of hard rock would like them a lot, they are relatively clean for that kind of speaker and can play very loud. Good for movies too.

But for critical listening to music, ick!

Oh, dear. As I look back at what I said a year and a half ago, I'm a bit amazed that I was so forgiving of this speaker. In fact, the speaker is quite boomy and very bright. For listening to music, I find it very fatiguing after about a half an hour, and it sounds very unbalanced; vocals are are overwhelmed by bass guitars, and cymbal crashes are shrill.
I will confess, though, that I still think it's a pretty good speaker for home theater. Its boominess works well for action movies, and I hardly notice the brightness at all when I'm absorbed in the movie.

I bought this speaker when I still worked at Best Buy, and it cost me $500 with my employee discount. I don't think it's a bad speaker for $500, if you plan on using it almost exclusively for home theater; but if you're looking for a more musical speaker and were planning on paying full price, I recommend looking at speakers by PSB or Paradigm instead.

Clarity, Balance, LOOKS

Needs a subwoofer

I listened to a pair of the Rsf1000's over 5 years ago and I really wanted a pair unfortunately the $2000+ Best Buy wanted was too much for me at the time and like most people I didn't want to spend that type of money at Best Buys anyway. I did go ahead and buy the 5 speaker and sub satellite system that worked great. Months later when they were going out of business I looked over 3 states to find some 1000's but they were all gone. I purchased the last pair of rsf 600's and never looked back! Matched with the satellites as surrounds and center channel with the sub for LFE my system sounded nearly as good as those costing $$$$ more in the audiophile stores. I have since purchased the rsf 200's (for rear duty) and the center channel and it sounds GREAT. I don't profess to be an audiophile but I know what sounds good. I listened to the Def Tech, paradigm and others that may with certain types of music have a very slight advantage but barely noticible. Becoming more experienced in home theater I have changed ever component twice in 3 years to the tune of the cost of a NEW CAR but I can't find ANY speakers that rival the sound without spending at least $3000-$4000. The speakers do need a good subwoofer for HT so I did purchase a DEF TEC to compliment the sound and the black lacquer finish; I think that I'm done with speakers for a while. I know that within the next year I plan on revamping the HT again with HDTV and 6.1 or 7.1 but right now the Eosone will definitely be the last to go if at all!

Maybe I just need to find more Eosone speakers for the additonal duty in the rear!
