Features
The A-605/70 is the budget-minded answer for both residential and commercial
in-ceiling speaker applications. The A-605/70 employs an 6½-inch polygraphite
woofer cone and a ¾-inch soft swivel dome tweeter for great sound on a budget.
Other amenities include a UL listed integral rear enclosure and a built-in multi-tap
transformer, enabling the A-605/70 to be used with either 8 Ohm or 70/100 Volt
audio systems. The A-605/70 provides full-range performance while exceeding
building code compliance. The metal enclosure reinforces bass frequencies allowing
a deeper and more controlled bass response. A powerful magnet, ensures accurate
dynamic reproduction.
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. Sophisticated computer modeling techniques are used extensively in
the RBH Sound speaker design process.
A switch connected to the tweeter allows you to custom tailor the sound to your
tastes. This switch is located next to the woofer on the front baffle of the speaker
and has three positions: +3dB, 0dB, -3dB. The +3dB position increases output of
the tweeter, the -3dB position decreases the output of the tweeter relative to the
woofer. The 0dB position is the factory setting and generally provides the most
natural response from the speaker.
The use of a 70/100 volt transformer allows many speakers to be used together by running
a connecting wire from one speaker to the next, without concern for the impedance seen
by the amplifier. A 70/100 volt amplifier must be used to accomplish this.
WARNING:
Refer to the installation and wiring diagrams sections to properly install
a 70 volt system.

Installation
IMPORTANT:
This product must be installed in accordance with your local area’s
building codes and regulations. This may require use of an additional support bracket,
depending on the installation. The speaker
has been encased in a back can with the
terminals on the outside of the back can
for easy installation.
1. To install the wire push the end of
the binding post in and run the wire
into the hole on top of the terminal,
then release the terminal to securely
attach wire to the speaker.
