An exclusive and unique feature of the M3 integrated systems is the option to use
separate amplifier channels to power the tweeter and mid-bass driver individually (bi-
amping). This configuration allows an external active crossover to be used, enabling
electronic crossover filter customizations, level matching and phase adjustments.
BI-AMPING
The M3 integrated systems are shipped configured for a single channel per speaker. To
connect a standard single channel input simply connect the + and - wires to the two
exposed terminals.

FEATURES
- TEXTURED, CO-POLYMER CONES - micro texture improves high frequency response.
- PROPRIETARY FRAMES - heavy gauge steel for increased stiffness, low resonance.
- BUTYL RUBBER SURROUNDS - impervious to environmental degradation.
- ALUMINUM DOME TWEETERS - smooth audiophile response.
- DIAMOND AUDIO QUALITY - 3 year warranty with authorized dealer installation.
- BI-AMP CAPABLE CROSSOVERS - individually voiced, model specific crossover
topology - configurable for active crossovers.
M3 INTEGRATED SYSTEMS
To power the tweeter
separately from the mid-bass
driver, remove the two leads from the
tweeter terminals and connect the
tweeter amp channel + and - wires
directly to these terminals. To protect the
tweeter in all cases, a passive filter network
consisting of a PTC and a 12dB/oct filter is
always in-line with the tweeter. Bypassing
this filter for special installations is possible,
however it is not recommended and will void
warranty. Please consult your dealer before
attempting this.
To Bi-amp, simply remove these two
connectors and connect tweeter amplifier.
