RBH Sound WM-24, Owner'S Manual

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 over-driven. This device is engineered to work 900%
faster than a fuse.
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.

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.
