The Active Advantage

There are a number of advantages to using an active

speaker system over a passive loudspeaker:

• Theinternalcrossoverisactive,anditslowpower

circuitry operates on line-level signals. It does not

waste speaker-level power like a passive crossover with

large coils, caps, and resistors.

• Theinputsignalsarecrossedoverbeforetheyreachthe

ampliﬁers, so each ampliﬁer only receives the correct

frequency range for its driver.

• Theampliersaredesignedspecicallyforthese

speaker load impedances. There is no guesswork as

to what load each ampliﬁer has to drive, so they can

provide maximum acoustic output from the speakers,

yet minimize the danger of speaker damage due to

overdriving a lesser ampliﬁer.

• Theconnectingwiresbetweentheamplieroutputs

and the drivers are kept to a minimum, so the damping

factor of the ampliﬁer isn’t compromised by the

resistance of long speaker cables. In addition, all the

power from the ampliﬁer is transferred directly to the

drivers with no speaker cable losses.

• Theacousticsumoftheoutputsfromthetwodrivers

is optimized electronically, as well as physically, so the

amplituderesponseisatandthereisnolobingerror.

• Thepresenceofactivecircuitswithinthespeaker

cabinet allow the designer to add on extra details, such

as a high quality mic/line input section and optional

accessory modules.

In short, all the complex interconnected components

in the system are designed to work in harmony with each

other to produce the best possible sound.
