A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...
The "RM" in the speaker name (e.g. RM40) stood for "Ribbon Monitor". The RM40, RM/X, 626, RM30, RM-V60, and RM-50, all used a "Neopanel" mid-range, and a modified Aurum Cantus ribbon tweeter, except for the RM50, which used a Beston ribbon tweeter. Woofers had woven carbon fiber cones and phase-plugs.
Dome tweeter with a membrane with 25 mm diameter made from titanium; from a JBL TI 5000 loudspeaker box, c. 1997. A dome tweeter is constructed by attaching a voice coil to a dome (made of woven fabric, thin metal or other suitable material), which is attached to the magnet or the top plate via a low compliance suspension.
The term loudspeaker may refer to individual transducers (also known as drivers) or to complete speaker systems consisting of an enclosure and one or more drivers.. To adequately and accurately reproduce a wide range of frequencies with even coverage, most loudspeaker systems employ more than one driver, particularly for higher sound pressure level (SPL) or maximum accuracy.
The 50 KW has 50 watts of power, a 10" woofer and a 3.75" tweeter. It has "2-channel operation", with "Channel 1 optimized for microphones with an XLR and a 1/4" input" and "Channel 2 optimized for line level and keyboard sources with 2 phone jack inputs and 2 RCA inputs" [12] The 50 KW is wedge-shaped, so it can be used as a monitor for a ...
The midwoofer-tweeter-midwoofer loudspeaker configuration (called MTM, for short) was a design arrangement from the late 1960s that suffered from serious lobing issues that prevented its popularity until it was perfected by Joseph D'Appolito as a way of correcting the inherent lobe tilting of a typical mid-tweeter (MT) configuration, at the crossover frequency, unless time-aligned.

The following table lists the following properties for piezoelectric materials The piezoelectric coefficients (d 33, d 31, d 15 etc.) measure the strain induced by an applied voltage (expressed as meters per volt).
Piezo is derived from the Greek πιέζω, which means to squeeze or press, and may refer to: PIEZO1, a mechanosensitive ion protein; Piezoelectric pickups for guitars and other musical instruments; Piezoelectric sensor, a device that converts differences in physical force to generate voltage; Piezoelectric speaker, a type of small loudspeaker
