Canalis Anima loudspeaker

The Anima is a two-way loudspeaker from Canalis Audio, a new enterprise of longtime importer Immedia, of Berkeley, California. Canalis is thereby related to Spiral Groove, and Canalis speakers bear the Spiral Groove logo on their terminal plates. Spiral Groove, founded in 2005, makes turntables; their SG2 ($15,000) was favorably reviewed by Brian Damkroger in the June 2010 issue. Canalis makes at present four models of loudspeakers, all designed in collaboration with noted engineer Joachim Gerhard, formerly of Germany's Audio Physic. All Spiral Groove and Canalis products are made in the US.

For the time being, Spiral Groove/Canalis products come only from the electromechanical end of high-performance audio, not the purely electronic (let alone digital) end. The focus on addressing electromechanical rather than electronic challenges appears to be a consequence of Immedia founder Allen Perkins's rubric of "Balanced Force Design," which posits as the overarching design goal the optimal integration of "materials, performance, function, manufacturability, and aesthetics." This focus is, as well, a consequence of Perkins's interest in vibration and resonance control—not surprising, from a turntable designer.

The Canalis line comprises the Anima, a stand-mounted, rear-ported two-way ($3250/pair); the Anima CS, a tricked-out Anima with a ¾"-thick bottom plate of solid stainless steel and upgraded crossover parts ($6000/pair); the Cambria, a floorstanding two-way ($5000/pair); and the Allegra 2.0, a modular loudspeaker with a two-way, sealed-box upper cabinet crossed over to a bass module containing two 8" aluminum-cone woofers ($17,500/pair).

The Anima's driver complement consists of a ¾" hybrid tweeter that combines a textile surround with a metal dome and is used in all Canalis models, and a 5" anodized aluminum-cone woofer. The Anima measures 16" H by 10" W by 10.5" D and weighs 14 lbs. Its front panel tilts back at an angle of about 9°. High-quality Eichmann terminals permit single-wiring only.

Canalis states that the Anima has an impedance of 8 ohms, a sensitivity of 86dB, a crossover frequency of 1900Hz, and a frequency response of 44Hz–33kHz, –3dB. They also claim that the design of the crossover incorporates a proprietary "Joachim Gerhard DC-Module" that minimizes the baffle-step effect.

The Animas come very securely packed in a sturdy double carton, along with a very complete guide to room placement. The review pair was very handsomely finished (including the rear panel) in low-gloss polyurethane in a shade Canalis calls Licorice, but which I would call Jacobean—think of the chunky, heavy, very dark brown wooden furniture from the reign of James I. Other finishes are natural, which Canalis calls Honey, and a warm, reddish, medium-brown that Canalis calls Cinnamon.

The Anima is not provided with a grille, so there are no grille-mounting attachments on its front panel. The front of the bottom plate is slightly recessed, and carries a metal strip embossed with the brand name, as well as threaded metal inserts to secure the speaker to its dedicated stand ($1500/pair), or allow the use of Spiral Groove's proprietary resonance-control pods, the Strange Attractors ($800/set of eight). These go between stand and floor, or between the speaker and a shelf or third-party stand. The Attractors' metal upper hemisphere is anodized the same bright red as the blind nut that secures the bolt that pierces the three crossed legs of the stand.

Although I consider the Canalis Anima to be a new loudspeaker, reasonable minds might differ on that point. Readers with long memories may recall Wes Phillips's enthusiastic July 2007 review of a loudspeaker, also called the Anima, from a company called Sonics by Joachim Gerhard, and also imported and distributed by Immedia. Earlier, while at Audio Physic, Gerhard had designed the very-well-received Step and Step SLE loudspeakers. The Sonics by Joachim Gerhard Anima was a refinement, at that time, of his earlier design.

I assume that the Step (which remains, I assume in further-evolved form, in production from Audio Physic) was named to highlight what its makers perceived to be an unusually successful implementation of baffle-step compensation. Baffle step refers to the rise in a loudspeaker's frequency response that comes about because, above some frequency primarily related to the front baffle's width, its output is directed mostly forward. Whereas, below that frequency, heading down to the deep bass, soundwaves are increasingly omnidirectional, and less energy, therefore, is directed at the listening position. Although a baffle-step graph, when read from left to right, might suggest a rising treble, I believe the acoustical phenomenon is actually one of weakening perceived bass.

Baffle-step compensation, of course, is only one aspect of the "Squeeze it here, it bulges there" art of loudspeaker design. Time alignment of the outputs of woofer and tweeter is an issue, and then there's always the Allison Effect, aka the floor-bounce effect: a frequency-specific bass cancellation related to the distance from the center of the bass driver to the floor. And other factors.

Regardless how they came up with the Step name, I think it's fair to say that, in the early 1990s, the Audio Physic Step's crisp, clear, dynamic sound and remarkable imaging represented a new paradigm in minimonitor sound, and one that was warmly received by many reviewers, including Stereophile's Jack English in his October 1994 review.

The Sonics Anima that Wes reviewed in 2007 had front and rear panels of marine-grade plywood; its other panels were of high-density fiberboard (HDF). It had a grille, which Wes found made its optimal sonic contribution when removed. The Sonics Anima's tweeter and woofer, I was told by Allen Perkins, were essentially the same as are now found in the Canalis Anima. Indeed, Perkins told me that during the development work on the Canalis Anima, he took pains to ensure that the cabinet's internal volume remained essentially identical to the Sonics version. As it turned out, the new speaker could even be shipped in the same packing materials as the older.

I was reading the article when something jumped out at me: $800 for a sheet of bamboo plywood!  

The only way I can figure out how to pay $800 a sheet for plywood is: pay $200 for the largest/highest quality sheet of bamboo + $600 tip?

I love the use of bamboo as a building material as it is head and shoulders above MDF, but seriously why lie about what it costs?  High quality bamboo plywood has a fairly stable commodity price; any supplier charging $800 per sheet is high as a kite. 

Also: the F3 is 60Hz not 44Hz , the bass load behavior is a classic reflex with 24db/oct. roll off not a QB3 design with 18db/oct. , and their does not appear to be a BSC network on the woofer (as JA hinted) not even a "proprietary Joachim Gerhard DC-Module"  (god help us). 

I can see why manufactures lie about specs, cost, design, and features but Stereophile get your $%*#  together and stop posting the manufactures' ad copy in your articles like it is actually true.  This is lazy and irresponsible

I thought that the claim of $800/sheet plywood, which is a price I more usually associate with ritzy countertop materials, was worth mentioning, so I did.

The fact that you found so much to sink your teeth into in one brief evaluation, to me at least, not only shows that I was sweeping nothing under the rug, but also that I am neither lazy nor irresponsible.

Have a nice day.

I hope you didn't get the impression I was picking on you as most every writer on the Stereophile staff does the same thing.  

It is obvious that the several inaccuracies in the article came from Allen Perkins; and it is understandable why he would want to stretch the truth, who doesn't want to sell a product that defies the laws of physics (Hoffman's Iron Law).  

But my question is why do the writers on this staff reiterate the bogus claims that manufactures make; hench giving validity to them?


P.S. John, 

Including several inaccuracies in your article, no matter the source, does not show that you sweep nothing under the rug.  By not checking your facts you are doing a disservice to your readers.

Hello OneMic,

The price of the bamboo is from invoices from our cabinet maker and its based on part yield. I can buy bamboo for as low as $130 per sheet. If I want parts without internal voids the part yield per sheet goes down fast. When he calculates yield this is what the persheet cost would be. Its an easier way to explain our QC that trying to tell people the cost per panel of a cabinet.

John was very professional in his review practices with us. He asked lots of questions and questioned the answers. We have both a facebook page and web site where we can be contacted directly. If you want to call our claims bogus or say I stretch the truth do it directly. I never claim to do anything outside the laws of phyics.
