Hello my fellow audioholics! :)

I'm glad to be back to write up my impressions of these speakers which I just received today! Let me preface this by stating that this is in NO way intended to be a professional review as my selection of music is heavily biased to what I mostly listen to and how I hear it is my personal preference. I am using these strictly as a stereo pair for music reproduction, no subwoofer.

INITIAL IMPRESSIONS:

The speakers were well packaged and double boxed. The Cherry finish is truly stunning- having not owned a pair of nice speakers before, these are very nice indeed. I was a bit concerned as to what it would look like because on the website, the finish appeard more orange in color. Those thoughts quickly dissipated when they arrived. The cherry is a rich, dark real wood veneer. In my opinion, these are furniture grade cabinets and for $300, I feel like I got away with a steal!

SETUP:

I'm powering the RC 10's with a Harman Kardon HK AVR 145- 50 watts x2 into 8 ohms in stereo mode. I set up the receiver in analog bypass mode which basically shuts off all digital circuitry and allows straight amplification with no bass managment. All source material are compacts discs played on a rather inexpensive Samsung DVD player connected to the receiver via analog outputs. Speaker wire is 14 gauge. The speakers are set on 31 inch stands that came free with my purchase. Perhaps the most crucial aspect: I am situated roughly 5 feet away from the speakers and the speakers themselves are 6.5 feet apart and slightly toed-in. My listening room is roughly 10’x 15’.

LISTENING TESTS:

1.) Album: Barber Violin Concerto, Artist: Isaac Stern, NY Phil conducted by Leonard Bernstein, Track 2.

Considered by many to be one of the premiere violin concertos of the 20th century, Issac Stern gives an impassioned rendition of this masterpiece. The one thing that always caught my ear on this track was how harsh the violin sounded on my previous pair of speakers (JBL E20's). At some points, the treble was just too piercing that I had to lower down the volume just so that I could finish the piece.

On the RC 10’s there were immediate differences right from the opening lines of the piece. Stern's violin took on a voice of its own and was not all harsh; the higher registers shimmered and were a real treat to listen to. (a testament to the quality tweeters.) When the entire orchestra comes in during the climax of the first movement, I noticed how rich and full the sound was while each section was delineated and clean with no more muddiness of sound. The cello section sounded especially good and full- the 5.5 woofer belies the more than capable bass extension. Having played this concerto myself, I can say that I am well aware of what this piece 'should' sound like. To my ears, the violin sounded as everything it should be and then some- Stern commands the voice of the violin with such vigor and grace all at the same time.


2.) Album: 1812 Overture, Artist: Leonard Bernstein and the NY Phil, Track: 1

In my book, this remains the most epic of overtures. One can sense the triumph and victory amidst the brass fanfares, soaring strings, carillon and CANNONS! The overture begins with a rich yet subtle cello line, played in a rather slow and somber fashion. The RC 10’s executed the exact articulations with ease. One thing that surprised me while listening with the RC 10’s was how well the entire spectrum of sound was represented. There are moments in this piece when there’s so much chaos going with the strings, brass, winds, carillon and cannons playing simultaneously. On my JBL E20’s, the carillons were the hardest to hear being buried beneath the other instruments. In a subtle way, the RC 10’s let me hear the giant bells ring back and forth, as if the bells encircled the outer perimeter of the orchestra.

3.) Album: Queen Rock Montreal: DISC 2 Track 9: Bohemian Rhapsody

Queen is a band I wish I had discovered much sooner than I had. Having said that, the ubiquitous “Bohemian Rhapsody” is one of the most outlandish songs ever penned and on this particular live recording, Freddy Mercury and crew give a rousing rendition of this rhapsodic masterpiece. Freddy’s vocals were spot on and the RC 10’s let me hear every enunciation. The piano intro at the beginning of the song was fleshed out with exceptional clarity. Bass and electric guitars rocked away and Roger Taylor’s drum kit was precise. Again, even without a subwoofer, the speakers held their composure and allowed me to fully enjoy this track at satisfying volumes.

4.) Album: No Line On The Horizon, Artist: U2, Track 1

The title track has been grown on me quite a bit since listening to this album for over several months. Buzz-saw guitars, synthesizer bleeps, chromatic chord changes, fantastical lyrics and soaring anthem-like vocals make this track a winner. One thought that sums up my experience of this song on the RC 10’s is a redefined sense of space. The RC 10’s created a sense of atmosphere within the track that I had not heard previously on my JBL E20’s. The sound was more open and defused, I liked this. The Edge’s guitar and Adam’s bass lines were effortlessly interwoven. Larry’s drum kit locked in everyone together. Bono’s vocals were somehow moved slightly forward of the instrumentation, which allowed for greater clarity, this I also liked.

FINAL THOUGHTS:

For just under $300.00 shipped and a free pair of speaker stands, I could not be happier with my purchase. The speakers are aesthetically pleasing and the sound quality is a treat for the ears. Energy suggests a break-in period of 100 hours and I realize that I conducted my listening tests after having literally taken the speakers straight out of the box. Still, I am amazed at the sound! To sum it up, what I liked best was that the treble had more of a weight to it, allowing a more realistic reproduction of instruments, especially string instruments. The woofer is more than adequate even without a subwoofer, extends evenly to the lower ranges without becoming boomy. Having paired my JBL E20’s with a 12” JBL sub before this, I would have to say I am quite content without a subwoofer. If anyone is looking for a pair of bookshelf speakers in the $300 range, do not hesitate to give these a try, my most urgent recommendation to anyone who enjoys music. Pictures to follow soon! :)

I am not sure if the RC-10 has the same tweeter as its bigger brothers. I AB'ed a pair of Martin Logan Vista XStat (C$2499.99 each) and Energy RC-70 (C$1249.99 each) a few weeks ago at the Future shop, and to my surprise the Energy sounded better. The mids and highs are smooth, more concert like to me than the ML. For some reason the ML sounded harsh when compared to the RC-70. The Energy also did way better in bass. The speakers were only powered by an AVR. I can't remember if it was a Yamaha or Pioneer but I do remember either way it was one of the top models.

I guess I could assume the ML would have done better with a more powerful amp in terms of bass, but whether it would improve on the highs and mids I am not so sure. Still, the RC-70 sounded so sweet to me that day. it made me wonder if I would have spent more on my Veritas had they been both available at the time.

Exact same and I'd still take the Vertias.....:)
But I still enjoy my 30's....BTW when did they get the ML line?

Someone just had a pair of 50's NIB for sale on Ebay for $599. I think that is the sale price for 30's. By the way, they did not sell. Seems like a deal.

At 5K a pair listed, it is hard to believe they can be found in any Future Shop but they certainly were found in the one on Dundas/Winston Churchill only about 3 weeks ago. They have the huge Vista XStat as well as the smaller XStat. The small one did not impress me at all but the Vista did, especially with brass and percusion stuff. They changed slightly as soon as the guy switched it to the RC-70. I immediately found the RC-70 had a better overall tonal balance while the ML had more emphasis on the upper mid to high frequencies.

After that day, I learnt to appreciate my 2.3i more, thinking less of the grass (like the B&W 803D or even the S) next door. Having said that, if you can find those ML in your area, take a listen for yourself. I found them a little harsh and borderline on being bright but we all hear things differently.

From what the Energy website states, all the speakers in the Reference Connoisseur Series feature a 1" Aluminum Dome Tweeter.

I have a pair of RC-10's that I recently replaced with a pair of Paradigm Studio 20's. The 20's are definitely, to my ear, better speakers and sound better in my situation. However, I paid four times as much as I did for my RC-10's!

The original MSRP for the RC-10's was a bit on the high side, but for $300, are an absolute bargain. They have very good bass extension for such a small speaker and the treble is as very smooth. I do not hesitate giving a strong endorsement of the RC-10's for anybody with a small to medium-sized listening space and room to keep them away from the front wall, due to the rear ports. (I have to place my speakers close to the wall, so the front ports on the Studio 20's help a bit in reducing the standing wave.)

I wonder what Klipsch is doing with the Energy RC line, as they are no longer available at Future Shop and the only other Energy dealer in my area no longer carries any Energy products. I think availability is drying up and they're being sold off at bargain prices.

Perhaps the RC's weren't selling well at the higher price and they're losing money on them. But that's complete conjecture on my part.

If anyone has a budget for bookshelf speakers in the $300 region, do yourself a favour and give them a listen.

I have to agree, since the RC 10's originally retail for $700.00 per pair, the $300.00 price tag is what lured me into making this purchase. The RC 10's came with port plugs to compensate for placement issues, however as I have found, this greatly reduces the richness and fullness of sound.

Will using speaker cable such as the ULTRALINK MX-2 provide any substantial difference is sound as compared to the 14 guage speaker wire I am using with my RC 10's?

Thanks in advance!
Personally I don't think it makes a difference at all, and that's a pretty hot topic from what i've seen around here.

And if the bcs title game is a blow out tonight I'm gonna try to give these speakers a serious listen. I've got htem hooked up to the lappy and its integrated sound isn't nearly what's in the desktop and the desktop doesn't have anything special, but I can definitely tell a difference. The lappy doesn't provide as much of the crispness and clarity i was hearing last night.

Well here we go. I'm going to do my best here to give everyone my opinions about these speakers, hopefully without saying all the same stuff as boboi.

First I'll give you the situation that i'm doing my listening. A month or so ago I decided to sell my logitech Z-5500 speakers i'd had in the office for about a year. They were good for gaming but I was working from home half the week, and they weren't cutting it for music at all. So I got rid of them and scored an older onkyo stereo receiver on ebay for like 40 bucks. It's a TX-800, I've got no manual and have no idea what the specs are other than it can push the RC-10's cleanly to a very good volume, esp sitting 4ish feet from them in the ~12x12 office.

They're sitting on the omnimount stands that vann's sent with the speakers for free. They're decent stands, but I couldn't for the life of me get the wire through the pedestal, my monoprice 14ga wire is pretty limp and after a while I said screw it.

So the audio is WMA lossless coming out of my desktop which holds an Abit IP35 pro motherboard. The intregrated sound is a realtek 886 I think, can't remember. All I know is that its a better quality solution than my toshiba laptop's sound. It's also running win7 64bit home premium.

Now with that out of the way I'll look at build quality and whatnot. Pulling them out of the pristine energy box that was inside a huge vann's box, I saw the solid vann's packing job kept external damage from occurring during shipping. Getting speakers out and unwrapped I immediately saw the color of the cherry is somewhat darker than I expected. If they were a couple shade darker they could have probably called them rosenut, assuming they didn't already have rosenut :) They are finished semigloss IMO, not high gloss like my EMP ti's in the living room which are def rosenut. The veneer is very nice, a subtle grain, nothing too crazy. It provides a great contrast to the face of the speaker, the brushed aluminum surrounding the tweeter and mid really adds to the look. I really like the looks with the grills off, I'm probably going to put the grills away permanently. Only downside I would have changed is the nubs the grills attach to aren't flush mounted, they stick out 1/4 inch or so. Overall great looking speaker, probably about on par with my EMP's in the living room in terms of looks.

On to the music listening!
I'm not a classical guy as much as boboi, but I am a pretty big dave matthews band fan. I think their music is a good test for speakers because of the variety of instruments and quality of some of their recordings.

I decided to change it up some and started with Warehouse 8: vol 5, track 1 is Rupunzel. Being a live track I was really listening for solid imaging and, being live, the decay of notes. Immediately wow, I've got them WAY too close to the wall, they're about 4inches off the wall. The low end was pretty boomy and inaccurate, but I have to deal with it, the wife won't let me move the desk any further out. So I dropped the 31hz 2 notches and 62hz 1 notch in WMP and that really cleaned them up. You might think that's cheating, but I'm doing what I can to compensate for my lack of ideal situation.

For those of you that don't know the song or the band very well, DMB, from my experience, almost always has the same setup. from left to right, violin, Dave in the center in front of the drums, then bass, then trumpet, then on the far right, the sax. Closing my eyes let me experience the imaging, dave right in the center where he belongs, violin just to the left, trumpet and sax distinctly to the right. I will say they needed just a touch of toe in sitting this close to them to get the imaging to line up well.

This song has some abrupt stop/starts esp at the beginning that allowed me to hear the decay very well and the RC-10's did very well. They were very accurate and remembering listening to some cambridge bookshelves recently that didn't handle it as well, I was happy.

I then moved to their latest studio album, Big whiskey. I sampled alligator pie and then seven right after that. Big change, the live album's aren't nearly as well recorded and mastered, which I expected and these speakers definitely brought to light. alligator pie is fairly crazy at the beginning and I was look for clarity, and it was there. I could still pick out the instruments with none of them or frequency being particularly overpowering.

Seven is very much different with more trumpet and a much slower pace. I noticed the high's are pretty smooth and detailed, but on this song, the cymbal was just a touch harsh IMO. I don't know, maybe I'm just not used to hearing them, I don't get to sit down for music listening in the living room as much as I'd like.

I moved to coldplay's viva la vida, track 6 which is Yes for my final song today. The wife had come in at this point and she wanted to continue listening to this cd after I had finished. This song was has some good mixes of electric, acoustic, and strings, along with some other stuff I didn't recognize :) Everything was precise and detailed and sounded great. Maybe not the best song in terms of dynamics and whatnot, but one I've listened to alot. I'm in love with the accuracy, they're such a HUGE step up over the logitech's, as they should be.

In conclusion, these things look as good as they sound, and at 300 bucks for not HUGE bookshelves that don't need run with a sub for music. I'm very happy with the purchase so far!

I do have a question: Do you plan to get a sub?
IF you crossover your speaker at let's say 150Hz to the sub you take away some of the strain on the mid.
I know your speakers sound fantastic, I heard very good things about these speakers but you'll be in the audio HEAVEN with a decent sub + the speakers you already have.
My 2c.:cool:
Of course there is always something more to buy; (next on my list is a blu-ray pet)

I've thought about cashing in my chase points and getting one off amazon as they have the best point to gift card ratio. But I'll probably wait a few months to make sure we have the funds to pay off all the xmas presents. Wife doesn't like me buying stuff when the bank account is low, even if it doesn't cost us any real money :( Plus, waiting will let me bank some more points.

The wife is (always) right:)
Plus - it gives you time to look around - read up about the subs in whatever the price range you decide; maybe you get a chance to "see" some of them "at work"
