Rayons Home-cinéma Caissons de grave

Si le home-cinéma est synonyme de sensations fortes, voici le complément idéal de votre système. Ce vibreur professionnel, adopté par les salles de cinéma dynamique (Imax) et les simulateurs d'avion, a été choisi pour les démonstrations à la presse du système "Home Video DVD Experience" de Warner Bros. En étendant la bande passante de votre système à 5Hz... vous entrez dans une autre dimension. Le décollage d'Apollo 13, la course de pod-racers dans StarWars Episode I, deviennent des expériences physiques extraordinaires au sens premier du terme. La révolution home-cinéma encensée par la presse internationale (cf. articles en anglais) !

Techniquement, le Buttkicker utilise un procédé de suspension magnétique breveté très différent des haut-parleurs habituels pour exciter des plateformes par inertie. Nous le proposons avec un amplificateur stéréo conçu pour alimenter 1 ou 2 Buttkicker.

Attention, l'impédance du Buttkicker (4 ohms) ne permet pas de monter l'ampli en pont pour 1 seul Buttkicker. Dans le cas d'un montage avec 2 vibreurs, il faut faire attention à la phase pour ne pas annuler les effets de l'un par l'autre.

Le système Buttkicker utilise la vibration du sol. Afin d'optimiser ses performances, il faut le monter sur une plateforme indépendante du sol de la pièce. Cette plateforme sera construite de manière très rigide pour distribuer uniformément les vibrations. Elle peut utiliser une ossature bois ou un châssis métallique avec un plancher vissé.
Il est important de monter ce plancher sur des supports amortisseurs souples (plus ils seront souples, plus l'effet sera sensible).

The World Of Tactile Sound
"In home theatre, or in real life, for that matter, there's two kinds of sounds that we experience. Audible sound is what our hearing system detects, and of course is what our speakers deliver to our ears when we experience movies or music. Tactile sound, on the other hand, is sound that we don't necessarily just pick up with our ears, but can also feel, either as air shaking and/or vibrations through the ground, the floor, the walls etc., caused by the mass movement of air. Subwoofers add immeasurably to the experience of a film, and movie soundtracks are produced with content targeted for subwoofers because of the realism and visceral effect that is possible with them."

"A tactile transducer is a device which is something like a speaker. The difference is that rather than driving a cone diaphragm to transduce input electrical signals to sound, an electromagnetic source, usually a voice coil, drives a substantial mass, which in turn imparts inertia on the outer enclosure, causing it to "shake." When this device is mounted against a fixture, such as a couch or the floor, you feel vibrations in concert with the low frequencies that have been channeled through the transducer. The result, in many cases, is a convincing feeling of realism and an emotional jolt with explosions, earthquakes, tornadoes and whatever else you can think of that can be felt."

"The ButtKicker™ shaker, from The Guitammer Company, Inc. ($699) is just one of these tactile transducers designed to rattle, shake, rock and roll you, depending on what you experience from them and what movies you're using them with. The ButtKickers have seen much action in the music world with the Backstreet Boys and Creed. Now, they're available to enhance the entertainment offered by movies in your home theatre, though the company has also recommended experimenting with them when listening to music with generous low frequency content. To put the ButtKicker to the test, several members of the Widescreen Review staff auditioned a movie excerpt with significant low-end content, and shared their impressions. They also reported their thoughts on the ButtKicker's performance as compared to the Clark Synthesis Tactile Sound Transducer™, which we reviewed previously (Issue 35 and in this edition) in a similar fashion."

"Worth noting here was how clean each response was, accentuated and in perfect synch with the onscreen action, not vague or buzzy, as was sometimes the case with an old subwoofer of mine."

"Musically, I found the ButtKicker to render very accurate percussion, particularly the jolt I felt in my chest at the thump-thump-thump of a good bass drum. This level of involvement works well with live tracks, and could also turn your best studio recordings into a private concert."

"Even as is, though, the ButtKicker is extremely spouse-friendly… You can and probably should turn down the subwoofer, to create a more balanced soundfield with no perceived loss of bass response, and cohabitants outside the room will scarcely hear a thing. For these reasons it is also a viable component for apartment dwellers (rubber isolation feet are another encouraged option)."

Highlights
"Fast, precise "shaking" action adds an entirely new dimension to movie watching at home
Extreme low end sensitivity and wide frequency response range deliver plenty of bass effects, including some you've never heard".

"The ButtKicker Rocks, Rolls And Kicks Butt!" By Perry Sun.

GIG Magazine (septembre 2002)

"Wow! I never imagined how actually feeling bass frequencies could make such a dramatic difference. Suddenly, I perceived things I'd never heard before - such as the subtle dynamic shifts in my bass player's performance. I locked in so tight with the bassist that, at times, he and I just started laughing."
