The tweeter's „swivel" technology allows it to be pivoted by up to 35 degrees, thereby enabling ideal sound
dispersion and perfect alignment to the listening area:

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls
in the central position – i.e. with "linear" amplifier output. Turning up the bass and treble controls too far
delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the
speaker units!
If the output of your amplifier is significantly higher than the rated power handling capacity of your
speakers extremely high volumes can physically destroy your speakers. This doesn't actually happen
often but you should be aware that it is possible.
Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium
volumes because weak amplifiers may overload much faster than powerful ones and this causes
measurable and audible distortion, which is extremely dangerous to your loudspeakers.
Always turn the volume down immediately as soon as you hear distortion! If you like listening to loud music
make sure that your amplifier can deliver at least as much power as the speakers' power-handling rating.
THE SOUND YOU CAN'T HEAR...
Amplifiers, tuners and CD/DVD players can all produce inaudible high-frequency signals – and this
doesn't only apply to cheap products. If your tweeters fail at low or medium volumes you should have a
qualified technician check your system components for dangerous inaudible signals.
