The Avalanche by Unity Audio follows the same sealed cabinet approach in order to preserve fast transients details and accurate bass reproduction. The 12” woofer fires the sound downward uses its low centre of gravity to reduce vibration and movement for a more detailed and clearer reproduction. A unique Aperiodic Vent allows for extended low frequencies all the way down to 22 Hz.
The same Low Frequency amplifiers as the Rocks and boulders are running in parallel for a total power of 150 RWNBSW*. Their output transformers are then mounted onto a heat sink with anti-vibration rubber mounts. In addition the Avalanche uses Burr Brown ICs throughout the custom input crossover, with a Burr Brown OPA627 Op Amp used to preserve the integrity of the signal and the best audio quality in the audio path.
The Crossover offers a choice of low-pass and high pass filters the former using a 4th order filter and the latter a 2nd order filter. In addition, the Avalanche features two preset selection to pair with Unity’s Rocks and Boulders. The R60 is meant to be used with the Rocks and has a crossover point at 60Hz while the B50 sets the crossover at 50 Hz to work with the Boulders. Further customisation is possible with both Low and high pass filters by setting the Avalanche to Vari Mode. Both Low and Hi Pass filters range from 40Hz to 120Hz allowing the perfection cross over with most systems.
Other appointments include a 180degree reversal switch, input gain, balanced XLR I/O and a foot switch bypass pedal. This allows for the bypassing of the Avalanche and the transmission of the full frequencies to the satellites monitors.
The Avalanche uses an extremely robust split chamber cabinet with dividing bracing partition and restrictive membrane feeding the second chamber. It also uses 24mm plywood with a laminated baffle. Dense rubber lead substitute is attached to the walls to reduce cabinet resonance and providing efficient internal damping.
