The high-end loudspeaker market has stayed quite static over the years, and boxes of all sizes and forms have become a necessary evil. Despite all the bracing, damping, internal absorption, a box behind a speaker just adds its own resonances. The dipole/open baffle loudspeaker is an improvement. With its radiation pattern in the form of 8 and the removal of the box, we greatly reduce the reflection of the sound on side walls and eliminate the enclosure resonances. Unfortunately, dipoles and open baffle speakers are often quite large and need large spaces.
At Eden Acoustics we were looking for the best of what a dipole loudspeaker can offer, but with a much more modest size and possibly improved looks. After many tests and measurements, we were happy to conclude that the best open baffle loudspeaker was one without any baffle… We used a separate bass module to downsize even more. The TÔMEI is the only open baffle loudspeaker to play full range with such a modest size. It’s equally at home in much smaller spaces. The TÔMEI is really the renaissance of the dipole!

Every TÔMEI active system comes with five channels of DSP, D/A conversion and amplification. One channel of amplification is dedicated to each driver for a total of 600 watts. The amplifiers offer load independent frequency response and nearly frequency independent distortion behaviour. An exclusive adaptive modulation servo technology corrects non linearities in parallel with the class D stage itself, reducing distortion to a very low 0.05% at rated power. These new generation Class D amplifiers can now compete with the best class A, AB or valve challengers on the market. Using only premium components, TÔMEI amplifiers provide a first class listening experience.
On the input side, a complete set of digital and analog inputs are available. These include USB, S/PDIF and balanced analog inputs. Digital signals benefit from low phase jitter clocks that drive all the data converters while minimum phase anti-imaging filters are used by the DACs to avoid pre-echo effects. The AKM AK5397 ADC incorporates very high common mode rejection / low noise balanced inputs and all signals are processed by the audio-optimized 32-bit/40-bit floating point DSP capable of up to 384 kHz performance. The USB Audio Class 2 input supports the high sample rate and full bit depth offered by the DSP.
Few active loudspeakers systems can claim such a high-end electronics package but during our three years of
development we took the time to analyse, listen to and choose only the outstanding.

STANDING IN FREE AIR
At the start, TÔMEI was an open baffle loudspeaker. The spatial projection abilities of these designs significantly exceed the spatial experience offered by traditional point loudspeakers. The OB also cancels side reflections, which further improves imaging. At Eden Acoustique, we carried on from there to finally remove everything except the drivers and so our Open Air Design was born.
If you measure such a system, you will find that from 400 to 2500 Hz, the midrange driver performs better in all aspects without a baffle with better power response, smoother frequency response and less distortion. Over 2500 Hz we are in tweeter territory and baffle or not makes no difference. Below 400 hz. this is another story and at bass levels, a baffle is beneficiary to get more efficiency and dig deeper. In the TÖMEI we solved this by using a stand-alone bass unit that sports a small baffle and sits low near the floor. To get omnidirectional bass, we use a crossover frequency below 100 Hz. Our multi-channel DSP controls the bass unit and gets articulate bass down into the 20’s from that 300 mm (12 inches) driver.

The TÔMEI Air is the perfect example of our Open Air Design architecture. They are full range loudspeakers and the perfect combination of outstanding sound quality and ground-breaking design. No more box, no more baffle… What is left is music so alive that for the first time you not only listen to a LIVE performance, you attend it!
“Those Canadian loudspeakers shine with an almost holographic playback, a 3D sound, completely detached from the speakers in the room.”
Sempre Audio – Germany
Every TÔMEI loudspeaker system is finely crafted of solid wood and acrylic parts to damp any resonance.
TOWERS: Each tower makes use of 9 acrylics diffusion ribs and comes with a solid american walnut wood support. The base is a 2-inches thick sculpted block of acrylics with specially designed, damped aluminum spikes.
BASS MODULE: The separate bass module employs a 1-inch solid wood baffle with stainless steel braces. It also stands on damped aluminum spikes.
CONTROL UNIT: Our ACU-01 unit is built of stainless steel that does not fade over time paired to solid wood and an acrylics front panel.
CABLES: The TÖMEI system uses twist’n lock speakon connectors, which improve the connection and are much easier to use. The bi-wire speaker cables are included with the system and they come from a renowned loudspeaker cable company in Scotland.
