INTRODUCTION

The StageFront Home Theater Solutions Loudspeakers are expressly designed for superior sonic quality in home theater applications. Each model employs advanced technology components that extract the subtle nuances in recorded music or the thunderous action sound in a movie. Models ending in “LCR” are intended primarily for front channel left/center/right placement or wherever a monopole design is required. Models that end in “FX” are designed for special effect placement. StageFront models are the perfect choice wherever quality of sound is the most important consideration.

INSTALLATION CONSIDERATIONS

RECOMMENDED AMPLIFIER POWER

For satisfactory performance, we recommend using a surround ampliﬁ er with a power rating of 20-150 watts for the Pro1770LCR and Pro2770LCR. We recommend an ampliﬁ er power rating of 20-200 watts for the Pro1870LCR and Pro2870LCR. Most loudspeakers are not damaged by large ampliﬁ ers, but rather by small ampliﬁ ers. If your system is playing at high levels, a small ampliﬁ er will run out of power very quickly and can create damaging “clipping” distortions. A more powerful ampliﬁ er will play at the same volume without distorting. See OPERATION on page 9 for more information about ampliﬁ er clipping distortion.

LOUDSPEAKER WIRE

Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or ampliﬁ er. For most applications, we recommend using 16-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. Every StageFront Pro loudspeaker features gold-plated, ﬁ ve-way binding posts that will accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors.

NOTE: THESE FIVE-WAY BINDING POSTS CAN BE CONNECTED IN SEVERAL DIFFERENT WAYS (E.G., BANANA PLUGS, SPADE TERMINALS, AND DIRECT WIRING).

When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect the wire and to meet local electrical and ﬁ re codes. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as loudspeaker wire must be run in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional audio/video installer, building contractor, or the local building and inspection department.

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number – the lower the number, the larger the wire. For example, 12 AWG is physically larger than 14 AWG.
