Marantz Studio Scope 4 monitors
Overview
The two-way Studio Scope 4 is a high quality bi-amplified loudspeaker, delivering impressive wide-range, high-output sound from a trim, space-saving design. It provides a level of acoustic performance that convincingly exceeds what you get from similar-looking consumer models, making it ideal for use in business, education and media production space-constrained settings.
High Quality Components
The Studio Scope 4 system is comprised of two matched cabinets. Each cabinet contains a long-excursion 4-inch polypropylene-coated woofer and a 1-inch ferrofluid-cooled tweeter. The tweeter is mounted in a proprietary waveguide that controls its dispersion, ensuring optimum listening-area sound coverage, free from the random splatter of too-wide dispersion designs or the restricted “flashlight beaming coverage of too-narrow dispersion designs.
The Left speaker contains the system’s stereo amplifier, rated at 20 dynamic watts per channel. The amplifier utilizes class A/B architecture. Class A/B amplifiers have superior clipping headroom and overload characteristics compared to the Class D amplifiers that are commonly used in conventional powered speakers, and this is a major contributing factor to the smooth sound quality of the Studio Scope 4.
In addition, the cabinets are made of Medium Density Fiberboard (MDF), a dense, acoustically-inert material that prevents the cabinet vibrations that would otherwise diminish the system’s clarity. This is a huge advantage over similar-looking consumer speakers, most of which use thin, vibration-prone molded plastic housings.
Easy to Use
Ease of use and flexible connectivity were also major considerations in the Studio Scope 4's design. Conveniently located on the Left speaker’s front panel is the system’s volume control, an Auxiliary input jack for connecting other devices and a Headphone output for private listening.
With its top-grade driver elements, Class A/B amplification, and resonant-free MDF cabinets, the Studio Scope 4 delivers a level of acoustic performance that is perfect for business conferences, educational settings, retail kiosk presentations/demonstrations and media production monitoring. If you require superior performance compared to conventional compact consumer powered speakers—even when space is at a premium—the Studio Scope 4 was made for you.
