Latest Bag End Speaker Powers Up
Apr 21, 2005 5:56 PM
Part of Bag End's Gem Collection of high-performance speaker systems, the P-Crystal is the latest speaker in the Barrington, Ill., manufacturer's inventory now available with an optional built-in 1,000W modular amplifier, the Minima One.
The Minima One is a high-fidelity, high-efficiency, 1,000W internal modular amplifier that weighs just 5lbs. More than 80 percent efficient, it provides more power to the loudspeaker and creates less heat in the amplifier than conventional designs. Incorporating patented technology, the comparison circuit of the module corrects each individual cycle. On average, every four microseconds, the one-cycle modulator transforms and amplifies the input signal into the ideal, natural pulse width modulation. Switching at 250kHz with the single cycle error correction ensures low distortion and high reliability.
In addition, the power-factor-corrected AC power input automatically, and continually, adapts to any voltage between 88V and 275V, thus making it convenient to power, and stable to use, on any power grid anywhere in the world.
The P-Crystal is loaded with a pair of 12in., high-efficiency, low-frequency cone drivers and a high-compression driver, with a 3in. copper voice coil driving a custom-designed oval, high-frequency wave guide. It provides high output and fidelity in a unique, wedge-shaped enclosure. System coverage angle of a single unit is 40 degrees vertical by 55 degrees horizontal at the -6dB points.
"Proving to be extremely versatile, the passive version of the Crystal has been employed in stadium systems, auditorium, church, corporate nightclub, and portable PA applications since its introduction just over 10 years ago, "says Bag End Sales Manager John Marcopulos. "Now, with the addition of the self-power option, it is even more versatile than ever."
