Care and Cleaning

To maintain speaker appearance, we recommend an occasional application

of furniture grade polish to the wood surface of the cabinet. To clean dust from

the grille cloth, use a vacuum with a brush attachment.

Features

At the heart of the MC Series loudspeakers is a proprietary aluminum cone

bass/midrange driver (speaker). The unique aluminum cone material combines

stiffness, low mass and self damping properties in a manner which allows

virtually uncolored presentation of program material. A powerful magnet,

extended voice coil and bumped back plate give the bass/midrange driver

high excursion capability, which ensures accurate dynamic reproduction. The

drivers are shielded by using a steel cup and an additional magnet to cancel

any stray magnetic eld which may cause interference with video equipment

such as tube televisions.

For high frequencies, a proprietary aluminum dome tweeter was developed.

This tweeter uses Ferro Fluid

liquid cooling, allowing the tweeter to handle

greater power while retaining detail and accuracy.

Steep acoustic slope crossovers are used to integrate drivers. The use of steep

crossover slopes allows high power handling, minimizes driver interaction

anomalies, and maximizes the clarity with which each driver is able to produce

its respective frequency band. A polyswitch, or current limiting device, is used

in the crossover to prevent damage to the tweeter if overdriven.

Cabinets are constructed of ¾-inch medium density berboard due to its inert

properties, thereby preventing sound coloration due to cabinet diffraction. The

thickness of the front bafes also prevents excess acoustic radiation. Large

oversized gold binding posts ensure a good electrical contact. Sophisticated

computer modeling and measurement techniques are used extensively in the

RBH loudspeaker design process.

Attaching Speaker Wires

When attaching speaker wire to the terminals, it may become necessary to

remove the black and red plastic protective inserts. To do this, loosen the

binder nut from the post by twisting counter-clockwise until the nut is removed

completely from the post. Remove the plastic inserts by pulling straight out.

Replace the nut on the post by twisting clockwise. A hole is then provided

in the top of the post to allow for banana type jacks to slide into. The nut is

tightened until the wire is secure. Remember to strip the insulation from the

wire prior to inserting the wire into the post. Repeat for the other speaker

wire(s) as necessary. (See illustration on following page).
