LOGOS 3A

Infrasonic Subwoofer

The indispensable element to bringing physical impact to the low frequency effects of your favourite movies. You do not hear the Logos 3A, you feel it act deeply into your body.

The Logos 3 A produces frequencies below 20 Hz. The human ear cannot hear them but they are indispensable to provide the physical effect felt during events such as a plane take off, an earthquake, or an explosion for instance. These are called low frequency effects (LFE) and need a specific channel that reproduces bass-only information. The LFE cannot be properly created with traditional home theatre speaker technologies. A new type of infra subwoofer speaker has thus been developed by Goldmund to add the physical impact that makes a movie experience a fully lifelike one. With a frequency range of 10 Hz to 20 Hz (-10 dB), the Logos infra-subwoofer fulfils its task with ease, dissimulated under your home cinema stairs or behind your seats.

The Logos 3A infra-subwoofer is available in two versions:

✔ a standard enclosure version of 57 W x 154 H x 44 D (cm). This version is passive.
✔ a customisable kit that precisely adapts to the stairs structure of your home cinema. This version is active.
