The MA-15D digital stereo reference monitors from Edirol/Roland provide high-quality audio in a compact form factor, perfect for computer-based audio applications. Each speaker has a 4" woofer and a 2" tweeter housed in a two port wooden bass-reflex cabinet. This results in an accurate sound with a wide frequency response of 70Hz to 20kHz.
The right-channel speaker acts as the primary, and offers bass and treble control knobs, two volume control knobs, a bass enhancer switch, and a digital input selector. Inputs include stereo mini and RCA phono connectors, as well as optical and coaxial digital inputs. The speakers support 24-bit/192kHz digital audio to work with today's highest standards.
