ARENDAL 1723, Handbook, Page: 20 / 57

Intelligent Powerhouse
We introduced the 550 IQ which already has set market-
leading standards. The Avalanche 800 IQ & 1200 IQ build
on the 550, but have been optimised, equipped with
additional features and highly refi ned for our hi-end 1723
subwoofers. Impeccable performance, conservatively rated
at 800/1200W, with capabilities that make the difference.
Subwoofers are not the same anymore.
Intelligent Technology
The term “intelligent” is rarely used in the audio
industry, especially for speakers and subwoofers. The
new Avalanche 800 IQ & 1200 IQ subwoofer amplifi ers
are two more exceptions from Arendal Sound, when it
comes to performance and technology. State-of-the-art
amplifi er, designed and developed from scratch to deliver
performance and features you could not get before.
The Avalanche 800 IQ & 1200 IQ boast killer performance
and offer features under their hoods that have never
been seen in the industry before. Multiple sensors in the
digital and analogue domain, from inputs to outputs,
to preserve dynamics and clean bass. It has a powerful
microcontroller (MCU) which, as the brain, controls
and reads all data passing through the signal fl ow. This
ensures that the signal is as unaffected as possible from
its original source to the subwoofer output.
Research and development over two years, fully customized
by Arendal Sound. The Avalanche 800 IQ & 1200 IQ are
smart and intelligent beasts in the world of amplifi ers.
