Stylos User's Manual

Midrange

Midrange. The middle frequencies

where the ear is the most
sensitive.

Passive crossover

Passive crossover. Uses no active

components (transistors, IC’s,
tubes) and needs no power

supply (AC, DC, battery) to
operate. The crossover in a
typical loudspeaker is of the

passive variety. Passive cross-
overs consist of capacitors,
inductors and resistors.

Phase

Phase. The amount by which one

sine wave leads or lags a second

wave of the same frequency. The
difference is described by the
term phase angle. Sine waves in

phase reinforce each other; those
out of phase cancel.

Pink noise

Pink noise. A random noise used in

measurements, as it has the
same amount of energy in each

octave.

Polarity

Polarity. The condition of being

positive or negative with respect
to some reference point or object.

RMS

RMS. Abbreviation for root mean

square. The effective value of a
given waveform is its RMS value.

Acoustic power is proportional to
the square of the RMS sound
pressure.

Resistance

Resistance. That property of a

conductor by which it opposes the
flow of electric current, resulting in
the generation of heat in the

conducting material, usually
expressed in ohms.

Resistor

Resistor. A device used in a circuit

primarily to provide resistance.

Resonance

Resonance. The effect produced

when the natural vibration
frequency of a body is greatly

amplified by reinforcing vibrations
at the same or nearly the same
frequency from another body.

Sensitivity

Sensitivity. Volume of sound

delivered for a given electrical

input.

Stator

Stator. The fixed part forming the

reference for the moving dia-
phragm in a planar speaker.

THD

THD. Abbreviation for total harmonic

distortion. (See Distortion.)

TIM

TIM. Abbreviation for transient

intermodulation distortion. (See
Distortion.)

Transducer

Transducer. Any of various devices

that transmit energy from one

system to another, sometimes
one that converts the energy in
form. Loudspeaker transducers

convert electrical energy into
mechanical motion.

Transient

Transient. Applies to that which lasts

or stays but a short time. A
change from one steady-state
condition to another.

Tweeter

Tweeter. A small drive unit designed

to produce only high frequencies.

Wavelength

Wavelength. The distance mea-

sured in the direction of progres-

sion of a wave, from any given
point characterized by the same
phase.

White noise

White noise. A random noise used

in measurements, as it has the

same amount of energy at each
frequency.

Woofer

Woofer. A drive unit operating in the

bass frequencies only. Drive units
in two-way systems are not true

woofers but are more accurately
described as being mid/bass
drivers.
