This pair of PM641 3-Way Studio Monitors from Fostex are designed for playing back audio in studio applications. They feature a 6.5" Kevlar woofer, a 4" Kevlar midrange driver, and a 0.75" urethane film laminated cloth tweeter, capable of producing 86 watts of combined output. A +/- 1dB adjustment at approximately 10 kHz and a +/- 3 dB adjustment at about 60 Hz helps you tune the PM641s to your workspace. Each speaker has both a 1/4" TRS input and XLR input allowing for multiple connectivity options.
6.5" woofer, 4" midrange and 3/4" tweeter driven by 50W, 18W and 18W independent power amplifiers respectively
The built-in channel divider provides ideally overlapped frequency crossovers for smoothest connections between the drivers
The midrange and tweeter are positioned symmetrically on the Left and Right to minimize the physical height of the enclosure boxes as well as to minimize the effect of diffraction
The woofer and the midrange are housed in a chamber inside the enclosure box to have little interference between the drivers
3-step level adjustments are provided for High at +1/0/-1 dB and Low at +3/0/-3 dB
The diaphragm for the woofer and the midrange is rigid with moderate internal loss, being made of highly elastic Kevlar
The tweeter diaphragm is UFLC (Urethane Film Laminated Cloth) soft dome type to reproduce any types of high frequencies while keeping its own transparency
