Care and Cleaning
To maintain speaker appearance, we recommend wiping them down with a clean damp soft cloth. To clean dust from the grille cloth, use a vacuum with a brush attachment.
Features
At the heart of the M Series speakers are proprietary aluminum woofers and midrange drivers. This special aluminum cone material combines stiffness, low mass and self- damping properties to allow uncolored presentation of the program material.
A powerful magnet, extended voice coil and bumped back plate give the bass/ midrange divers high excursion capability. This ensures accurate dynamic reproduction. The drivers are shielded by a steel cup and additional magnet to cancel any stray magnetic field that my cause interference with video equipment such as tube televisions.
Steep acoustic slope crossovers are used to integrate drivers. The use of steep crossover slopes allows high power handling, minimizes driver interaction anomalies and will maximize the clarity of each driver in its respective frequency band. A polyswitch, or current limiting device, is used in the crossover to prevent damage to the tweeter if
Sophisticated computer modeling and measurement techniques are used extensively in the RBH speaker design process. Cabinets are constructed from extruded aluminum. The cabinets also have a narrow profile to minimize cabinet diffraction. The speakers virtually disappear leaving only a deep, wide sound stage and pinpoint imaging.
