Cambria

The Cambria is the latest design to come from Joachim Gerhard, and it challenges a few rules in loudspeaker design. Not that we're trying to be tricky. It's just that when advancements in technology happen, they can open doors that were previously thought to be closed.

The Cambria Low-Frequency Driver

In the Cambria, we have to thank driver manufacturer Seas for their newest 5-1/4-inch woofer. This driver is truly an exceptional example of low-frequency driver engineering. In a loudspeaker driver, we want mass to move...fast. And we want it too stop just as fast. In woofers the cone size in part determines its low frequency extension, but more cone area means more mass. More mass adds more inertia, and inertia causes loss of resolution, "overhang" and "smear" - sonic attributes to be avoided. That's where smaller drivers have an advantage over larger drivers...they have less mass and can start and stop faster. The Cambria mid/woofer excels because it has a considerable 30 percent more cone surface area than in typical driver of the same size.

Seas also developed a new manufacturing technique to make the magnetic flux field controlling the cone's movement more efficient and linear. This means the driver can travel further, start and stop faster, and remain much more linear than previously possible. What does this mean in real life? For its relatively modest size, this driver can move air like nobody's business. Faster and with less distortion thn ever before. All part of what makes the Cambria an exceptional loudspeaker.

The Cambria cabinet is incorporates a unique quarter-wavelength design. Quarter-wavelength enclosures are usually either a transmission line or a bass reflex (ported) design. The Cambria is a bit of both. It combines a long baffle with a carefully tuned port to create a perfect storm of deep and extended bass response combined with the speed and texture usually associated with small-driver loudspeakers.

The Cambria Tweeter

The 1-inch tweeter is a combination metal and soft-dome transducer. Loudspeaker designers, audiophiles and reviewers have long debated the merits of metal versus soft-dome - metal can yield excellent transient response, clarity and high-frequency extension, whereas soft-dome tweeters are often considered to be smoother and "sweeter". The Cambria tweeter combines the sonic strengths of both types.

The tweeter utilizes an extremely light and stiff aluminum-magnesium dome centered in a wide textile surround (most metal dome tweeters use aluminum, titanium or titanium-composite construction). The tweeter is distrotion-free far beyond the upper range of human hearing. Its large, supple surround allows increased output and lowers the cutoff frequency, which allows very low crossover points to be used. This unique tweeter is one of the key contributing sonic elements of Canalis loudspeakers, and is used in all Canalis models.

Addressing all the details, the Cambria contains premium crossover components, proprietary wiring, and the exceptional Eichmann CablePodTM tellurium copper speaker binding posts.

Cabinet Technology

When investigating cabinet material, our goal was to find the ideal balance between beauty and performance. We were not satisfied with the thinly veneered Medium Density Fiberboard (MDF) even though it is relatively inexpensive and easily manufactured. Because MDF is heavy and flexible, the sound pressure generated internally by the drivers turns the entire cabinet into high distortion panels. Instead, we chose remarkable 3-ply, 3/4 inch thick, cross-core Mao Bamboo plywood. Our plywood incorporated multi-dimensional constrained layer damping construction, which results in a naturally quiet material for loudspeaker cabinet. Mao Bamboo, actually a grass, is an efficiently grown renewable resource that is naturally beautiful and elegant. With custom furniture grade craftmanship and one of our three finish treatments, there is a Canalis speaker to compliment any decor, from traditional to contemporary. The Cambria is available in three finishes; Honey, Cinnamon, and Licorice.
