Totem Bison Twin Tower Floorstanding Loudspeaker at Vinyl Sound Toronto Canada

The Bison Twin Tower is a 2-way ported floorstanding loudspeaker from Totem Acoustic (Montreal, Quebec, Canada), available at Vinyl Sound in Toronto, Canada. The flagship of Totem's Bison series, the Twin Tower combines dual 5.25" copper-clad voice coil woofers operating in the same frequency domain with a 1.3" laser-etched textile soft-dome tweeter, crossing over at 2.5kHz via a 2nd-order handmade crossover in a lock-mitered monocoque Variable Density Fiberboard cabinet with Borosilicate internal coating and exclusive Delrin Claw decoupling feet. With a 90dB sensitivity, a 4-ohm nominal impedance, and a frequency response from 31Hz to 29.9kHz ±3dB, the Bison Twin Tower accepts amplifier power from 30 to 200 watts and stands 38.39 inches tall on a 7.36-inch wide footprint. Sold as a pair in White Oak, Satin White, or Black Ash, it includes magnetic grilles and 4-way bi-wireable gold-plated terminals. SoundStage! Hi-Fi's Doug Schneider described it as Totem Acoustic's "best-sounding and most beautiful speaker yet."

Dual Woofer Architecture — Lush Midrange and Bass Fullness

The Bison Twin Tower's defining engineering characteristic is its use of two 5.25" woofers operating simultaneously in the same frequency domain, rather than the single woofer of the standard Bison Tower. Both drivers share the crossover's woofer signal path and cover the same frequency range simultaneously, which doubles the radiating surface area compared to the Tower while maintaining the same driver topology. The additional cone area allows the Twin Tower to develop greater bass weight, midrange fullness, and dynamic scale without requiring a larger driver diameter, and at lower distortion at equivalent output levels than a single driver working at higher excursion. Totem describes this architecture as producing a lush, thick midrange and the bass fullness unique in the floorstanding speaker category, resulting in a speaker that SoundStage! Hi-Fi found delivered bass that was "deep, heavy and full" and gave the reviewer listening experiences of levels of detail in familiar recordings never heard before. The 2nd-order crossover used in the Twin Tower contrasts with the 1st-order crossover in the standard Bison Tower — the steeper 12dB-per-octave slopes of the 2nd-order design provide better rejection of the tweeter's and woofers' out-of-band output for this higher-powered, 4-ohm design.

Lock-Miter Cabinet, Borosilicate Dampening, and Delrin Claw System

The Bison Twin Tower's cabinet is constructed from Variable Density Fiberboard with a density of approximately 90% at the exterior surfaces and 65% toward the interior, reducing resonance nodes without the coloration of uniform-density MDF. The cabinet is assembled using lock-miter joinery, physically interlocking edges to create a structure Totem states is more than five times stronger than V-groove construction, with full internal horizontal cross-bracing for additional rigidity. The inner surfaces are coated with Borosilicate, an industrial-grade glass compound that Totem uses for acoustic dampening without the energy storage and gradual deterioration associated with polyester fibre fill. The handmade crossover is assembled point-to-point on insulated polymer with WBT silver solder rather than a printed circuit board. At the base of each cabinet, three Delrin Claw feet provide floor decoupling through controlled mechanical compliance — the HiFiReport noted that the Delrin Claw feet "break up standing waves and control surface resonance, tightening bass and heightening the soundstage." Thread inserts in the Claw feet accommodate optional carpet spikes.

Frequently Asked Questions

What is the Totem Bison Twin Tower?

The Totem Bison Twin Tower is a 2-way ported floorstanding loudspeaker designed and built in Montreal, Quebec, Canada by Totem Acoustic, and the flagship model of the Bison series. It uses dual 5.25" copper-clad voice coil woofers operating in the same frequency domain, paired with a 1.3" laser-etched textile soft-dome tweeter, in a Variable Density Fiberboard lock-mitered monocoque cabinet with Borosilicate internal coating and Delrin Claw decoupling feet. Key specifications include 90dB sensitivity, 4-ohm nominal impedance, and a frequency response from 31Hz to 29.9kHz ±3dB. The Bison Twin Tower is sold as a pair, recommended with amplifiers from 30 to 200 watts, and available in White Oak, Satin White, or Black Ash. SoundStage! Hi-Fi called it Totem Acoustic's "best-sounding and most beautiful speaker yet" in 2024.

Why does the Bison Twin Tower use two woofers in the same frequency domain?

The Bison Twin Tower's dual woofer configuration — both 5.25" drivers operating simultaneously across the same frequency range — doubles the radiating surface area relative to a single-driver design without requiring a larger driver diameter. The increased surface area produces greater bass weight, midrange fullness, and dynamic scale at lower distortion levels than a single driver working at equivalent output, because each driver moves less excursion to achieve the same acoustic output. Totem describes this as providing a lush, thick midrange and the bass fullness that is unique in the floorstanding speaker category. Both woofers share the same signal from the 2nd-order crossover network, creating what Totem calls a synergistic and remarkably musical relationship between the two drivers in the bass and midrange frequency range.

How does the Bison Twin Tower differ from the standard Bison Tower?

The Bison Twin Tower differs from the standard Bison Tower in four principal areas. It adds a second 5.25" copper-clad woofer, doubling the low- and mid-frequency radiating area for greater bass fullness, midrange lushness, and dynamic scale. The crossover is upgraded from a 1st-order to a 2nd-order design, providing steeper 12dB-per-octave slopes for better out-of-band rejection from the drivers. The nominal impedance changes from 8 ohms to 4 ohms, requiring a current-capable amplifier. The sensitivity increases from 88dB to 90dB. The cabinet is taller at 38.39 inches versus 33.47 inches, and the frequency response extends slightly deeper to 31Hz versus 30Hz. All other engineering characteristics — the lock-mitered VDF cabinet, Borosilicate internal coating, Delrin Claw feet, and handmade WBT silver-solder crossover — are shared between the two Tower models.

How does the Totem Bison Twin Tower compare to the Bowers and Wilkins 702 S3 and the Sonus Faber Lumina V?

The Totem Bison Twin Tower, the Bowers and Wilkins 702 S3, and the Sonus Faber Lumina V are all premium 2-way and 2.5-way floorstanding loudspeakers, but each reflects a distinct design philosophy. The Bison Twin Tower uses dual 5.25" copper-clad woofers in a parallel configuration with a 2nd-order handmade crossover, lock-mitered Variable Density Fiberboard cabinet, and Delrin Claw floor decoupling, built to Totem's artisanal Canadian standard. The B&W 702 S3 uses a three-and-a-half-way layout with B&W's Continuum cone midrange driver and carbon dome tweeter, with a different sonic character oriented toward high transient precision and forward detail. The Sonus Faber Lumina V is a three-driver 2.5-way design inspired by Italian instrument-making traditions, with a warmer and more romantic tonal character. Listeners who value the combination of expansive holographic soundstaging, lush midrange, and deep bass fullness from a speaker of manageable physical proportions will find the Bison Twin Tower a compelling option to audition.

What amplifier does the Totem Bison Twin Tower need?

The Bison Twin Tower has a 4-ohm nominal impedance and a recommended power range of 30 to 200 watts, requiring an amplifier stable and capable into a 4-ohm load. Despite its 4-ohm impedance, the 90dB sensitivity means the Twin Tower achieves high listening levels with modest amplifier power, making even 30-watt amplifiers usable in smaller rooms. Totem specifically notes the Twin Tower pairs well with a broad array of electronics, including integrated amplifiers, valve amplifiers, and AV receivers. SoundStage! Hi-Fi noted the speaker came alive with tube amplification in the tradition of other Totem designs, while solid-state amplifiers also perform effectively. Current-capable integrated amplifiers from Simaudio Moon, Naim, Bryston, and Hegel in the 50 to 150 watt range into 4 ohms are natural pairings.
