Bottom Line:   
These are one of the best speakers I've had. Very open and broad sound stage to them. Very elegant look with the silver color drivers and magnetic grills. It's a very soothing sound to it, can listen for longer periods of time with no listening fatigue. I like the deep cabinets and they give awesome low end with ease. If find on the the used market in decent condition you should jump on them as you'll come to adore them.

well just wrote a review and hit reset on accident so this is going to be short and sweet......audiitioned and shopped for 3 months. side by side comparison to veritas 2.3, klipsch rf, paradigm, b&w, and snell (no comparison but for fun) I chose the c-9...

they sounded very close the the veritas, veritas were better but not by much in my opinion. these play loud and clear and I have no need to upgrade. I am running a arcam dv-79(incredible), denon 3803, ati 2505, and the matching surrounds center and sub.

50% off at Good Guys. I paid only $650 for these babies. Talking about wanting to upgrade at the perfect time. My previous set of towers(sonys)were o.k. for HT but no where close to where I wanted to be musically. Notice I said o.k. for HT. My new C-9's R a completely different story. After about that 30 hr run-in mark I couldnt help it I had to get em going. I put on rush hour 2. It was a completely different movie. The sound coming from these speakers is simply amazing. Crystal clear and a nice in depth midrange. I've been playing music non stop since I got em. They work great for my HT & Musical needs.I'm sure the bass area is great but I wont comment on that because my 12 Energy sub takes care of that area. Nice slender design and very well built all around. They look excellent with the grills off but I cant go that route.(Curious hands) These are all around great speakers and if you can catch them at 50% their a steal.

Bottom Line:   
As with most speakers, give these a good 30 hrs of run-in before listening critically. Initially they will come off as somewhat dry and dark, give it time and you’ll be rewarded with some seriously smooth music. First of all, I’m still amazed at the bass these narrow column type speakers reproduce; it’s almost like an optical illusion. You see this tall skinny thing reproducing incredible bass, and you know there is a sub hidden---somewhere. The C-9 has 2 bass ports; one in the front near the bottom, and a second port on the back, about midway up. I would imagine the combination of the tuned ports and the 18” depth of the cabinets explains the room energizing bass. And these pups dish-out some serious, tight bass. They plunge 6Hz lower than my previous dual-8” towers. I noticed in the Soundstage review of the C-9, they had to push the speaker much farther than they typically do to get any reading of distortion in the lower bass—impressive, and exactly what I experienced; deep, clean well articulated bass.

I have to take a second to mention the binding post. These are very impressive; they look like WBT binders with a large heavy grade clear plastic knob surrounding the gold plated screw-down. It makes tightening a tool-less proposition, as you can really get some torque on the posts. Very Cool. BTW, the C-9 is not bi-wireable.

Also, quick mention of the grilles; they are magnetized—no posts to break off or wear out, easy on, easy off. The magnets are also damped to eliminate vibration. Again, very cool. I did all of my listening with the grilles in place.

The tweeter is nothing short of magnificent. It does everything right. Not too bright, not too laid back. Crystalline and airy without being prominent or etched. The crossover must be very well engineered, as I can’t detect any transition from the mids. There is a very smooth tonal neutrality about these speakers that almost sounds like a single full-range cone. I kept thinking to myself “these remind me of my AR9Lsi’s in a BIG way.” The easy-going, extremely listenable sound has you running through your CD library as if someone is going to take your system away tommorrow. What’s really sort of a paradox is that although they sound a touch laid-back, they are at the same time quick and articulate. Very nice blend.

Comparing these to the V.2 Paradigm Reference Studio 60 ($1600/pr) and 100 ($2300/pr), it all becomes clear. The Studio 60 is out-classed. It just isn’t capable of the deep, cleanly rendered bass lines, and the C-9 gives nothing away in the midrange/treble. The Studio100 is a more apples to apples comparison. Though the Studio 100 has a touch deeper bass, the C-9’s smoother upper-midrange and linearity in the extreme treble gets the nod. I will say the Studio 100’s mid and lower midrange is impeccable, and the overall tonal balance, top-to-bottom, leans ever so slightly in the Paradigm’s corner. For $1000 more, it better.

Comparing to my Athena AS-F2’s ($600/pr), the C-9 is less bright and in-your-face. Treble is sweet, without being over-bearing. The midrange soundstaging is better, probably due to the smaller 6.5” driver, and a touch more neutrality. The AS-F2 has very good bass, but just doesn’t dig quite as deep, with as much ease as the C-9. The big difference was clear when pushing the speakers hard. The Athena’s would tend to unravel a bit at high volume, becoming a little unsorted. The C-9 just kept sounding better and better, the harder it was pushed---almost like it was saying to me “that all you got, punk?”

Again and again while listening to the C-9’s I kept thinking of how much their tonal character reminded me of my early 1980’s AR9Lsi speakers. I even mentioned it to my wife, twice. The entire time I was writing notes for this review, I was looking for the right word….then it finally hit me…“alluring.” The Energy Connoisseur C-9 is alluring. It drags you into the performance and makes you want to listen to every track, just to see how it’s going to interpret the next note.

Bottom Line:   
Half off at good guys can you believe it? I love these things, the bass is incredibly accurate. I have yet to hear a bassline outside of the range of these speakers, and they have revealed a few basslines I didn't know existed. Sound good at low volumes, too. Pretty good range. If you are in the sweet spot be prepared for bliss as these speakers sound incredible when you are listening to well recorded music. Simply put at full price these are still good speakers but if you can get them on sale at good guys get them even if you don't need them! They are the only piece of audio equipment Ive heard wether car stereo, headphones, home stereo or boombox, that I cant really say I'd change anything about them. This excludes high dollar stuff in the showrooms. $1500 plus
