The modest-looking speakers from Blumenstein Audio belie the capabilities contained therein.

We’ve reviewed the Seattle company’s Thrashers, speakers light on looks but heavy on ready-to-rock, garage-grade power. The somewhat more refined single-driver Orca Classic monitors, paired with one of Blumenstein’s Dungeness Classic subwoofers, impressed our staff.

Combining the new Orca Mini monitors with two of Blumenstein’s new powered Dungeness Max subwoofers takes the system to the next level. Having two subs in the 2.2-channel system—which starts at $1,800—augments the Orcas with greatly improved low frequencies. Though matching Orca stands are available, each subwoofer begs you to set an Orca on top of it (placing vibration-dampening material between the units, of course). And with separate enclosures, the subwoofers and monitors can be independently toed-in, and there’s plenty of room atop each subwoofer cabinet to slide the monitors forward or backward.

Hull and Rigging

Blumenstein offers its cabinets—made from nothing but wood, glue and finish—in either birch wood or bamboo. The latter option is available with natural, caramelized, or two-tone finishes. Blumenstein uses non-toxic linseed oil instead of varnish to give the wood a delicate sheen.

The front-ported Dungeness Max has a rectangular footprint of 7.75 by 11.25 inches, which makes it easy to slide in between furniture, and with a height of 22.5 inches, it can fit easily under a desk or table. The Max features a 25-watt built-in amplifier and Blumenstein says it will reproduce frequencies as low as 27 Hz.

The Orcas sport a single pair of binding posts on the back for banana plugs, spades or bare speaker wire. As a powered subwoofer, the Dungeness Max has a knob on the back that controls power and volume. A second knob below that adjusts the crossover point from 60 to 180 Hz. Then comes the wiring…

Blumenstein offers a few ways to connect the subs into an audio system; the easiest requires simply running parallel split sets of speaker wires from a single amp terminal directly to the Dungeness and the Orca;my biggest complaint is that the subwoofer binding posts are tiny, spring-loaded connectors, like those on my old NAD 3020 integrated amp. While easy to use, they’re so small that they limit the gauge of wire you can use.

If you have a preamp with line-outs and a standalone power amp, the amp will drive the Orcas directly, while you connect the Dungeness to the preamp using RCA cables. When using two subs, the left one connects to the left preamp line-out and the right one connects to the right line-out.

Diving In

With two standalone Orcas used as desktop monitors placed about two feet away, the sound is mighty impressive. The lone driver does a very good job with imaging, projecting convincing audio into the soundstage. During the Zero7 song “Destiny,” the Orcas present Sia Furler’s voice fatigue-free and with nuances that reflect the emotion of her performance. Other instruments panned far right and left float into the periphery, beyond the plane of the speakers.

Of course, a speaker this size does have bass limitations. With the subwoofer pair connected, low notes join the acoustic presentation. The ability to adjust the toe-in of the subs independently and the crossover point allows you to tailor bass response to your preference without affecting the Orcas.

With an Orca atop each Dungeness Max and the resulting columns about 10 feet from my listening seat, the Orcas deliver a convincing sonic image, with vocals remaining slightly warm yet highly believable. Compared to near-field listening, the experience is akin to moving back several rows in an auditorium. There’s a bigger overall picture, but with broader dispersion, the density and tangibility of the musical elements decreases. The Dungeness Max subs create solid and tuneful bass, but larger listening rooms—like mine, at 17 by 20 feet—might be a bit too much for them to tackle. In a bedroom, den or smaller-sized living room, they offer very satisfying bass, room-filling sound and a highly enjoyable overall musical presentation.

With a wide-dispersion driver, the Orcas are not too fussy with placement, and because they’re small, the speakers are easy to adjust. For the subs, you can employ simple tweaks of placement and volume to generate just the right amount of low-end augmentation for your needs. The combined system proves incredibly versatile and fulfilling. With hours of listening, I need to keep reminding myself that the Orcas start at just $500 per pair.

Yes, there are better and more resolving speakers out there. However, the efficient Blumensteins offer a very high performance-to-price ratio. By selling unnecessary components like speaker grilles and stands as optional accessories, Blumenstein is able to offer the Orca speakers at a very reasonable cost, allowing those on a tight budget to start with a stereo pair and then add subwoofers later.

For those with $1,800 on hand, the discounted 2.2-channel package is an especially good choice. While this system doesn’t offer the refined look some buyers may be after, the simple beauty of the wood finish will appeal to many, and the sound quality you’re getting for the price makes the entire system a major consideration.

As an advocate of single-driver speakers—longtime TONE readers might remember that I started out with a pair of Lowthers as my reference speakers—I find something totally beguiling about them, though they are often misunderstood, perhaps because of their deceptive simplicity.

You might think that the appeal of single-driver speakers is a complete no brainer, because they don’t have crossovers for the audio signal to contend with, but in my experience with single-driver speakers, the power you feed them is everything. Because these speakers have such a delicacy about them—and the Orcas are no different—picking the wrong amplifier will give you dreadful results. Much like with OTL amplifiers, the result is usually either magical or somewhat flat. And if you’ve had the latter experience, you didn’t do it right.

Interestingly, both sets of Blumenstein speakers I’ve heard here at the TONE studio have sounded incredibly good with the $90,000-per-pair Pass Labs Xs300 monoblocks I use as my main reference. They also sound spectacular with a vintage Harman Kardon A-500 integrated tube amplifier. Oddly, the 300B-based push-pull amplifier from Nagra does not produce magic with the Orcas, though the 845 SET monoblocks I have on hand do. And so it goes, my personal favorite amplifier for driving these exquisite little speakers is the SIT-2 First Watt amplifier (also by Pass Labs), which produces 10 watts per channel from a single gain device. (Look out for our upcoming long-term review for more details.)

When you get it right and you don’t tax the Orcas with Audioslave at maximum volume, you will be shocked at just how deep into the music these little speakers let you hear. If you aren’t going desktop/near field, I suggest a room about 11 by 14 feet or thereabouts.  Music that is more vocally focused, without massive dynamic swings, proves enveloping. The first Crosby, Stills and Nash album is absolutely dreamy, as is Yim Yames’ Tribute To. For that matter, anything mostly acoustic or with sparse vocals will truly blow you away through this system, which reveals just how much music is lurking in your favorite recordings.

Just as you wouldn’t drag race a 400-cc sport bike against a liter bike, don’t expect the Orcas—even with the subwoofers—to blast AC/DC at concert-hall levels. But with the right recording, these speakers will not only shine but also make you appreciate the journey more than you ever thought possible, especially for the price. If you’ve never had the single-driver experience, I can think of no better place to begin your journey than with the Blumenstein Orcas. You may never want to leave.

One of the signs of a mature audiophile is whether they have a true garage system—not the wife’s old Lloyd’s faux-wood tuner/record player/cassette, but an actual receiver, disc player and speakers. Chances are the electronics are at least 20 years old, but the true pride is often in the speakers. Placement usually either involves a couple of L-brackets or, for the more adventurous, eyehooks and some length of chain. It can be problematic when the speakers are needed for an outdoor event away from the garage/workspace. I would not recommend taking your home speakers to the park gazebo.

Out of this madness comes Blumenstein Audio with what may be the most useful, multi-purpose and durable solution, the aptly named Thrashers. Blumenstein generously calls the finished look “industrial design.” In truth, the speakers look like something straight out of a Jeff Foxworthy special.

The review pair comes with an oriented-strandboard (aka chipboard) cabinet. Two cabinet upgrades are available: a fir plywood front or a complete fir plywood cabinet. Each cabinet measures 17 by 13 by 12 inches. The port and speaker jacks are mounted in the front panel below the 1-inch super tweeter, which is crossed over at about 10 kHz; an 8-inch Pioneer Bofu driver is also mounted in the front panel. With everything on just one side, there is less to worry about when inebriated friends decide to help move them about.

To make the review as real world as possible, I power the Thrashers with my 1980 Harman/Kardon 680i receiver, Magnavox DVD/CD player and 16-gauge speaker wire. I place the speakers on a shelf in my garage 6 feet apart and 5 feet off the floor. Much of the listening time transpires while I work on a home project, with plenty of contemplation and hopped adult beverages, and with the TV on mute during the World Cup. With their 92 dB rating, the Thrashers take precious little effort to play loud and clear, and they are designed to be manhandled, both physically and sonically.

The Thrashers sound like a quality budget set of nearly full-size speakers. Vocalists, whether Tom Petty, Melissa Etheridge, Roger Daltrey, or Rihanna, sound far more lifelike than if they were reproduced by the well-cared-for rack systems of yore. The crunchiness of vocals comes from the limitations of the recordings, not the Thrashers. Robert Plant’s eviscerating vocals during “Stairway to Heaven” are scary realistic. The front port helps deliver ample bass down to 45 Hz, even when placed against a wall.

One afternoon out of boredom, the teen neighbors bring over a mixed disc of hip-hop, rap and popular music. They listen to the first song and turn up the volume a couple of times. During the second track, they begin texting. Next thing I know, a car pulls up with three of their friends. The girls begin dancing to Rihanna, while the boys punch one another and act like bloodhounds. The spontaneous listening ends only when the neighbors are called to go to a ball game. The Thrashers are like the ultra nerds in high school who everybody ignores until test time and then everyone needs to sit near them in order to pass the class.

Upping the game with a Vista Audio i34 integrated tube amplifier makes the overall sound more sultry and sweet, and an SET amplifier would probably take it further, but why bother? Whatever the combination of factors, the Thrashers sound better than any $229 dollar speakers have a right to, hands down. For those few rare audio souls who have come across and rescued a tube amp awaiting the garbage truck, the Thrashers are the mates.

As luck would have it toward the end of the review period, I’m invited to a large picnic at a nearby park. Seizing the opportunity, I toss (well, not quite) the Thrashers and receiver in the back of my pickup and head for the park. Discovering the area doesn’t have any electrical outlets, I plug the Thrashers into my pickup with the speakers sitting on the tailgate, and soon the park is filled with music. Cranking up Frampton Comes Alive! brings out the air-guitar enthusiasts, and several people compliment me on the great sound system.

Sure, you could go to Goodwill and maybe find a pair of speakers that don’t suck for $50—but the odds of that happening are somewhat slim. Or you could get out the power tools, make a few trips to Home Depot and build your own pair. Hats off to you if you’ve got the fortitude for that exercise. I say send the folks at Blumenstein Audio a couple hundred bucks and break out the beer. Carry the Thrashers, slide them, dent them—it’s all about the sound and carefree portability, which these speakers offer in spades. Just a hint: Keep a pair of work gloves handy, as the Thrashers do shed splinters on occasion.

Publisher’s note: After auditioning the Thrashers with everything from an $88,000 pair of Pass Xs300s to my Sansui 771, I decided that I need them. Per Mr. Marcantonio’s suggestion, they are my new garage speakers. Rock on. —Jeff Dorgay

I’ve got a soft spot for single driver speakers.  While they don’t do everything right, the level of coherence and midrange purity exhibited by a great single driver speaker system is intoxicating.  The Orcas from Blumenstein Audio, combined with their Dungeness subwoofer are even more so, because now this setup has some serious bass, so I guess it’s not really a single driver system.

No, they still don’t play AC/DC like my Focal Maestro Utopias, but the Orcas/Dungeness combo will only set you back about $900, and that’s pretty cool.  Again, everything has its strengths and weaknesses.  The $1,500/pair KEF LS-50s are imaging masters, the $1,149/pair Vandersteen 1Cs (reviewed this issue) are incredibly musical all-rounders, and the Orcas are masters of tone – and isn’t that just fitting?

As with any great single driver speaker, the Orcas have an extremely wide dispersion characteristic, so they are not as position critical, from either speaker or listening chair placement, to get a full-bodied sound with a big soundstage.  And thanks to the combination of a wooden port and strategically braced cabinet with no sound deadening material, the Orcas don’t waste mechanical energy converting the signal to music.

Though a fairly young guy, designer Clark Blumenstein brings serious chops to the table. Formerly working with Cain and Cain loudspeakers, he has also spent time in Japan, apprenticing with Hal Teramoto, master driver maker at Feastrex in the summer of 2008.  One listen to the Orcas and you know he’s absorbed a lot from this experience.

Not just for the desktop

While these speakers are absolutely sublime as the anchors to a spellbinding desktop system, they can fill a decently sized room with sound, as Clark and Molly Blumenstein found out when they delivered the Orcas right after the Consumer Electronics Show early this January.

As they have an 89dB sensitivity rating, and possessing no crossover, you might be thinking “perfect candidates for a great SET amplifier.”  And you might be right.  We’ve had great results with our 845 monoblocks, and even though they are not SET, the 20wpc push-pull 300B amplifier from Nagra.

No one was more surprised than yours truly, when we heard a major difference going from the 20 watt tube amplifiers to the enormous Pass Xs300 monoblocks.  Yes, we were crazy, hooking up an $84,000 pair of solid state monoblocks to the diminutive Orcas, barely bigger than the power meters on the Xs300s, yet it worked.  Not only did the soundstage explode in all three directions, these little speakers distinctively revealed the differences in amplification handily.  Pretty damn impressive for a $500 pair of speakers.

Yet as cool as the Orcas are, they still sound a little, well, small without the matching subwoofer.  And for the extra $400, it is a must-purchase, taking these speakers from intriguing to serious.  Its six-inch driver in a small ported cabinet is small but very mighty, reminiscent of the powered woofer that Spica used to make.  Featuring adjustments for crossover frequency and output level, the Dungeness can be connected via line level outputs or directly to the speaker outputs, in a similar manner to REL subwoofers.  We used speaker level for two reasons – it was easy and with many people using these speakers in a modest system, and possibly not having access to an extra pair of variable outputs, this will most likely be the more common way these speakers will be used.  Five minutes’ worth of tweaking and the sub/sat balance was set perfectly.  Bottom line – these are incredibly easy speakers to set up, another bonus.

In the main listening room, alongside the mighty Focals, these little wonders proved intriguing, filling the room with aplomb. Recordings more towards the sparse side really make these speakers come alive.  Paul Weller’s self-titled album proved particularly groovy. With no crossover to introduce distortion or time/phase errors, the vocal purity is tough to beat.  And while these small speakers can only move so much air, at modest volumes they are eerily realistic.

Moving the Orcas out of my 16 x 25 foot main listening room into the 10 x 13 foot room in my house is much better.  Putting the sub close to the corner of the room for maximum bass reinforcement and bringing the speakers about four feet out in the room (much like I would with a pair of Rogers LS3/5As)  provides as nearly an immersive experience as listening on the desktop.  These speakers are absolutely wonderful in a small room.

However, the desktop is pretty cool

With the Orcas on the desktop between a computer monitor and the Dungeness tucked well under the desk, out of sight, it’s easy to forget that there is even a sub in the system, it integrates so well.  Listening to these little speakers extremely near field, the soundstage is encapsulating – sorry, headphones just don’t do this.

Playing to their strengths, I run through a medley of vocal-heavy tracks.  CSN’s “Helplessly Hoping” is magnificent, with all three vocalists clearly delineated, floating in front of my head – totally trippy.  Crowded House’s “Whispers and Moans” is equally lush, with the speakers disappearing in a three-dimensional presentation that is totally stealthy.

Though large scale rock is not the Orcas’ true strength, they handle AC/DC well at modest volume, close up.  “For Those About to Rock” comes through loud and clear, with good distinction between Angus Young on lead guitar and brother Malcolm on rhythm guitar, providing the necessary bite and texture. Lee Ving’s “Wife Is Calling” has the necessary grit, but pushing this too far reveals the limitations of these diminutive speakers – the point is reached where the soundstage just collapses and becomes one-dimensional.  Back off just a tad from this point and it’s all good.

A great combination

While there are a number of choices in this price range, this combination from Blumenstein Audio is fantastic, doing so many things incredibly well.  If you’re looking for a small speaker system that not only plays way bigger than its size suggests, but one that truly captures the tonal richness locked away in your favorite recordings, you need to give these a listen.  And if you’re a tube/SET listener, all the better.
