Germany is world-renowned for their contribution to the world when it comes to immaculate automobile design (BMW & Porsche), but Germany also contains an exceptional audio manufacturer that consistently hits the top ten with most audio critics when it comes to designing floor standing speakers, center channel speakers and their Digital Movie Series of loudspeakers which are specifically designed for home theater use. Even before the company was founded in 1972, the main four men who created Canton were working in the field of audio design for many years and each founding member was a huge enthusiast when it came to audio. The Canton name roughly translates to mean “To sing music” in English, so you can see how much passion for the musical element of audio design these founders were bringing to the world even in the nascent beginnings of Canton.

Audiophiles who regard top quality low-end as the main driving component of their entire audio system have grown to hugely respect Canton for bringing out the first satellite subwoofer system in 1979 that pretty much set the standard for subwoofer design even thirty years later. To ensure that their engineers could thoroughly calibrate the exact measurements needed to further push audio design to new heights, the owners of Canton built their own anechoic chamber in the late 1980’s. Not a company to rest on its laurels, their next step was to design its own PC software that would lead to the development of DC technology which actually improved substantially the impact and overload tolerance of the bass reproduction found in every speaker in the Canton product line.

It was at the beginning of the 1980’s that saw the first floor standing speaker from the Ergo product line being manufactured for mass consumption, and Canton’s engineers developed their own version of a hybrid-amplifier to drive each speaker chassis installed into the Ergo loudspeaker line. The Ergo 609 DC contains a wood-veneer cabinet that is designed to deliver clear and precise audio for the price of $3,200 a pair. I visited my favorite home theater store in Las Vegas, Premiere Home Entertainment, to check out the Ergo 609 DC.

Overview

These speakers stand over 40 inches high and are 12” in total width while weighing in at 50 pounds each.  They were a nice shade of burgundy that brought out the wood cabinetry design of the 609’s. The 609’s come with the color option of various shades of wood veneer, including burgundy, cherry and ash. This speaker is rated at 170 watts of nominal RMS output power and maxes out at a total RMS output power of 320 total watts, plenty of wattage needed to handle a large audio system.  The connectors in this loudspeaker are all gold-plated, while bi-amplification and bi-wiring are an integral design element added to the Ergo product line of floor standing speakers. The crossover frequency is measured at 3500Hz, 300Hz and the SPL output level is rated at 88.3 db while the nominal impedance of these speakers clocked in at 4-8 ohms.

The see-through black metal mesh grille covering each speaker barely hides the speaker’s two 8-inch woofers with the 1-inch tweeter and 7-inch midrange cone contained inside the wood cabinets. The tweeter’s cone material consists of an aluminum-magnesium hybrid that contains a silk surrounding.  This allows the tweeter to absorb sound distortion emanating out of the cone before it escapes the speaker’s cabinet. This tweeter is outfitted with a connected piece that contains the cone and the voice coil, thus eliminating high heat dissipation, which of course results in much better handling of the sound flowing through the Ergo speakers.

Upon closer examination of the 609’s, the mid-bass and main woofers used in the speakers contain dark anodized aluminum cones that have concave dust caps made out of the same material. All four drivers that are a part of this speaker series are magnetically shielded, so the consumer won’t have to worry about causing damage to their old CRT TV set if they have not yet upgraded to a LCD or plasma HDTV.

The Ergo product line contains wave-geometry woofer surrounds that increase the speaker’s ability to reproduce low-end bass elements to the overall audio soundstage.  The shape of the speaker baffles design were helped along with their layout by incorporating sophisticated computer processes which prevent acoustic rebound reflections coming from the edge of the speaker’s cabinets.
