RM/x review, part 2
« on: 7 May 2005, 07:55 pm »
I finally had a little more time to play with these this afternoon, and I did some listening to check out dynamic range and power handling. (Yes, that means I got to play them loud).

The speakers are still crowded into my living room and I’m still doing nearfield listening, because there’s nothing else I can do, given the speaker position. So I’m not going to talk about imaging. I still don’t know how well they will image (except that’s it’s going to be pretty damned well, I can tell that much already.) Nor have I gone through the frequency response drill with them. All that’s going to wait another month, when (in theory) the Soundroom From Hell will be complete enough to take in speakers.

--

There are plenty of high end speakers that have delicacy and precision, but no real power. I’m not just talking about volume – almost anything can get loud. I’m talking about that annoyingly overused word, Authority. The ability to get the gut involved in the music, to pull you in, using precision and strength.

Maggies (ahem. that's Magneplans, darling) and a variety of electrostatics come to mind as beautiful speakers which don’t quite do this. It’s not just a feature of thin panel designs, either – I’ve heard a set of Krell speakers, machined out of a chunk of aluminum, that had no power to grab the soul, no matter how much you played with the volume.

I already know the RM/x has precision in spades, from my last test. You only have to try well recorded piano and human voice on them once to know that aspect is covered. But how about some overwrought, emotional music? What about something that demands both precision and power?

I considered putting on Scheherazde (Rimsky-Korsakov), but that takes a certain mood and I didn’t think I was going to enjoy an orchestra, under volume, planted in the nearfield. I’ll save that for the finished stereo room, with a few more feet between the speakers and myself.

So I put on Polia’hu, from Winter Solstice 5. I wish this album were better recorded, but it’s a collection of artists, which means a collection of engineers, which means you get what you get. The Polia’hu cut is a mixture of  echo-treated nylon string guitar and plucked piano. Winston delights in the left side of the keyboard, and I don’t know how the album was miked, but it sounds like a microphone was practically parked on the lowest piano string. The result is a deep, rich, rolling, space-filling sound, not very piano-like, that sounds dull on weak speakers and earthshaking on good ones.

Especially at 100dbC @1.5m, which is more or less how I was listening.

And the RM/x were absolutely up to this. Not being a professional reviewer (and not having much time for those folk), I’m not going to slather adjectives on with a trowel. But with the preamp dialed to 0db gain and the subwoofer off, the room filled with a rich, powerful, and yeah, authoritive rendition of a piano going where pianos rarely go. There was absolutely no sign of strain, no sloppiness, no bloat whatsoever. Every quivering harmonic came though, and at the same time the speakers flawlessly rendered the higher pitches, finger-squeaks and creaks of the guitar. Note that I have not bi-amped these speakers. Plenty of speakers would exhibit traces of confusion with this combination of sounds, and would lose their grip on some aspect of the music. The RM/x just stood there and asked for more. I stopped turning it up when the meter got to 110db – the speakers still weren’t straining, I was at the limit of what I could personally process, and I’d proved what I wanted to prove - and anyway, the radiators in my living room were starting to rattle, despite the cardboard I’d rammed in.

For grins I cut in the subwoofer, set the crossover to about 35Hz, and ran it again. The sound did not improve, and in fact I had to turn the sub almost all the way to zero to get close to the previous richness of sound. There is music in which I think a sub is an advantage, even with the RM/x, but in their particular piece, which is extremely open (just two instruments and a very simple arrangement of tones), the RM/x handled it cleaner, and much more emotionally intensely, alone. (I should note that the sub is an Earthquake Supernova, which I don’t consider real audiophile material. I have it mostly for movies. I’d planned to go with it until I saved up money, and then look into a Hsu or a VMPS sub – and now I’m not sure I’m going to need to.)

Any doubts I had about RM/x and power, or bass handling, are now put to rest. It’s all there, possibly not razor flat (I won’t know about that for another month), but it’s entirely capable of reaching as far as it needs to, to accurately reproduce any music you want to hear.

Dymanic range was also a treat. I know there are speakers out there that go to pieces if you play a deep powerful note and a complex series of quiet higher notes, even when the amp is providing plenty of clean power. Usually I suspect cabinet resonance or a flawed crossover in these cases, at least if I know the amp is entirely capable. I haven’t heard anything better than the RM/x in this area; Brian clearly understands cabinets and crossovers. If memory serves (and after 6 months it might not), these beasts managed this trick better than $40,000 Dali speakers – one of the few rich-man’s audiophile speakers I’ve heard that I think is worth the pricetag.

So. In theory, sometime around June 15th, I'll have my soundroom functioning – a 25x28x12’ space, with ceiling treatments, wall treatments, dedicated power, and all the soundproofing in the construction I could afford. (The finished floor won’t go in until December, unless I learn to install it myself, so it won’t be photograph-worthy, but I should be well on my way to having room nodes solved by then.) Party at my place (in Massachusetts)? Bring good music, your favorite better-than-thou interconnects, and your chosen amps and preamps. And especially a TacT room correction system, if anyone’s got one, because I’m curious. We’ll make a day of it. :-)

Good review Scott.  I auditioned the Megalines at a local dealer after hearing the raves about them.  They were properly set up in a decent room with quality electronics, source, and cables.  I left thinking how much better the RM/X were at less than one third the MSRP.  In fairness, the pair I heard probably had too few hours on them to judge the bass and pretty hefty discounts are available even for new pairs.  Still, I would not have traded my RM/X for them.

Where the Megas blow me away is their effortless ability to fill vast space. They are huge speakers and they go in huge rooms and make them sound intimate. It simply takes a large number of drivers and a lot of power to do that; as massive as the RM/x is, it can't do the same thing. It doubtless could at 4 times the size, but then, well, it would probably cost as much as a Megaline. And I have trouble imagining going through the exercise of shifting the Megas around to get room modes down. What do you use, a fork lift?

Anyway, I don't have a palace or an auditorium to fill, and they are overkill in anything smaller, even if I had the cash.

Oddly, I hated the sound of the small Dali's, the Euphonia and so on. They sounded colored, and choked, somehow. Not what I expected.

Scott, Nice review.  

My RM/X's didn't start to image like they should until I finally moved them out from the front wall, and somewhat closer to the sides.  My placement/exact measurements (which means little to any other room) is in my gallery.  Once you get away from nearfield you'll be addicted, if not already.  Oh, and buy a cheap laser level.  The toe-in takes no effort with one.  I have them crossed about 2 ft in front of me.

Enjoy.

Ted

P.S. Gallery to be updated soon to show my new RM30C as center....

That room of yours is incredible.  I can't wait until I move back east in 6 months and have more space!

So I take it that your not going to exercise that 30 day return option?

Well, I dunno. I think I should probably trade them in for some nice Bose in-ceiling speakers (said to be the very last word in imaging), and maybe dump this cheesy brick-like Bryston amp and go for a nice Radio Shack receiver. The newest models have lots of glowing blue LEDs and things, so that makes them really cool. *noddle*

In other words, you can come for this system over my cold dead body.  :mrgreen:
