Sound levels
Our audio solutions deliver important sound
pressure levels (SPL) that can be harmful
to human health when exposed during long
periods. Please do not stay in close proximity
of operating speakers.
Risk of electrocution
To prevent the hazard of electric shocks, do not use
extension cords, multi-socket or any other connection
system without making sure metal parts completely are
out of reach.

Thanks for choosing the AUDIOPHONY® ACUTE series.
The ACUTE series features plastic speakers producing high sound pressure levels and designed to bring the best
performances of their price range.
We kept several criterias while designing these speakers:
- High power handling and unsurpassed sound quality.
- Wide and smooth basses and trebles rendering.
- Sophisticated ergonomy for transportation and installation.
The combined effort of our engineers allowed us to meet our expectations, they created a speaker series perfect
for any situation: Home Cinema, live performances, studios, ... etc.
About the housing
The ACUTE series speakers were designed to be among the most resistant molded speakers on the market. The
materials used ensure enough rigidity to eliminate parasitic noises.
Each speaker features rigging points to stack several speakers and baseplates to use speaker stands.
Even though they are incredibly good in their default configuration, their monitor-specific angles allow them to be
used as monitoring speakers.
