Watch out KRK! New kid on the block in powered home studio monitors

Question

Emotiva is a Web-based audio company that makes well-built, highly regarded electronics and speakers at friendly prices. They recently started a pro line. Their initial offering is a series of three powered monitors ranging from $399 to $799/pair. WIth the caveat that I haven't heard them yet, they look promising, and they have a 30-day evaluation/return period to take some of the anxiety out of an online purchase. They are, from left to right, the Airmotiv.4, 5, and 6, so designated by the diameter of their woofers. As you can see, the ribbon tweeters and cabinets grow in size with each model. As you can't see, so does the power of the internal amplifiers, from 50 to 100 to 210 watts per cabinet. Each driver gets its own amplifiers. For example, there are two 50w amplifiers inside each Airmotiv.5, which I consider the value leader at $599/pair.

The tweeter is a modern implementation of the Heil Air Motion Transformer of the 1970's. It's a membrane folded like an accordion. Instead of batting the air like a piston, it squeezes it, transforming a little motion into a larger soundwave. They're fast, clear, transparent, and can handle a lot of power. Similar tweeters are showing up in the new GoldenEar products and the Motion series from Martin Logan.

Each speaker has both an XLR and an RCA line level input, two knobs to contour the treble and bass, and a volume knob. With the right cable adapter you can run them directly from a computer or iPod headphone jack, from a mixing console, from a preamp, from a USB DAC. There are lots of configuration possibilities here. I can tell you that if I were putting together a budget home studio, a pair of these Airmotiv's would be on my short list of monitor candidates.

How do you think these would compare? They're a fairly local company to me, but I have no affiliation. I just like the idea of buying local.

Equator D5

Given that the vendor admits that at $299 "our margins are thinner than we anticipated," they're a new company, and the product is backordered, I'd be a little wary as to whether they'll make it. Emotiva has been around long enough to feel confident to launch a new pro line. The coaxial design has some attractive characteristics, but I'm more familiar with the folded ribbon tweeter (like Emotiva uses) and have confidence in it.

I'm not saying the Equator isn't a good value; it probably is and it may emerge above the fray. I'm just inclined to favor the Emotiva at this point.

There's a great new restaurant in town. Of course, I haven't tried the food yet, but the menu is nice and shiny. :rolleyes:

Given my familiarity with the folded ribbon tweeter and the broader reputation of Emotiva, a more accurate analogy would be that I've had several meals prepared by a chef who just got hired by a successful well-known restaurant, and therefore there is good reason to believe the food is worth trying out.

Having sold the original ESS speakers with them, way back when I can attest that they had upper mids and top end for miles. The challenge that ESS had was coming up with a low mid/bass system that could keep up. You had to get to the top of the line before you got a reasonable extension at both ends of the spectrum. By the response plots, it looks like they have that licked. Also, from the plots it looks like you're still going to have a smallish sweet spot. For most small studios that isn't an issue, though. I still wonder about the relative "speed" of the AMTs relative to conventional piston drivers.

Just for what it's worth, I never was crazy about KRK's, they wear me out after an hour or two. But they sure are ubiquitous.

Spot on. There are more and more really fast midrange drivers now than ever before. It's a combination of closer tolerances, lighter and stiffer cone materials (e.g., carbon fiber), stronger magnets (e.g., neodymium), and more rigid structures. For example, GoldenEar Technologies developed their own 4-1/2" midrange driver to blend with the folded ribbon tweeter. This midrange is responsive all the way out to 20Khz, and the reviews of their flagship Triton 2 (which I have heard) all remark how seamless the integration is between midrange and ribbon tweeter. These Emotiva powered monitors strike me as having a similar advantage. The bass drivers are made of a high-tech composite, they're equipped with phase plugs to help avoid "beaming," and having the amplifier power on tap right in the box should help when it comes to immediate signal transfer.

Concerning the plots, the off-axis treble drop-off is not too out of line and some drop-off is desirable for monitoring as it helps keep room reflections out of the playback.

I'm really happy with the Emotiva stuff I've got, never heard their regular speakers though (most of their stuff is 4 ohms).

I'm a big fan of ribbons though. Airy!

Bump because the price of the Airmotiv's has come down and they're on sale. The formerly $799/pair Airmotiv6's can be had for about $630/pair. The Airmotiv4's are $314.10/pair. Remember, these are powered. The Airmotiv6's pack 210 watts per cabinet.
