Introduction
The SR-1290 is a high-power, compact cinema surround loudspeaker that addresses the requirements of the new immersive sound formats. It features
a high-power, long-throw 12” (305 mm) low-frequency transducer with a coaxially-mounted 1.75” (44 mm) titanium diaphragm compression driver.
The coaxial alignment of the drivers occupies less baffle area compared to traditional over-under driver designs, reducing the size of the cabinet while
maximizing output capability. Coaxial alignment also creates a “point source” radiation characteristic, so all frequencies are perfectly aligned through
the crossover region, resulting in better sound quality. Since the coaxial driver inherently produces a conical dispersion pattern, the enclosure can be
rotated without any effect on the coverage pattern.
The loudspeaker’s 4 ohm impedance rating allows it to draw more power from the amplifier compared to an 8 ohm loudspeaker. For object-based
audio formats where each surround loudspeaker requires its own separate channel, this means more power will be delivered to each loudspeaker,
allowing them to produce maximum output from lower-powered, less expensive multi-channel amplifiers.
The SR-1290 is designed for safe and secure overhead mounting. The cabinet is constructed of 15-mm Baltic birch plywood with internal bracing for
superior structural integrity. The rear panel of the cabinet is fitted with six threaded insert mounting points that accommodate the standard bolt pattern
for most third-party bracket manufacturers. A set of four mounting points centered on the cabinet’s rear panel allows the use of a multiple angle
aiming bracket for ceiling mount applications where the loudspeaker needs to be aimed directly downward. Pre-installed speaker-side hardware allows
fast single-installer wall mounting, and brackets support down-angles of either 15° (standard) or 23° (optional). A traditional U-bracket (YM-400)
is also available. The compact black enclosure features the same styling as our other SR family surround loudspeakers, so you can easily combine
different models (for example, SR-1290 in front-screen locations and SR-1030 on side and rear walls) and maintain a consistent aesthetic appearance.

Installing the SR-1290
WARNING!:
Read and follow these instructions carefully. If the loudspeakers are not suspended properly, they could fall,
causing personal injury and damage to the equipment.
Rules for Suspension
• Consult a Professional Mechanical or Structural Engineer, licensed in the jurisdiction of the sound system installation, to review, verify, and approve
all attachments to the building or structure.
• Employ the services of a Professional Rigger for hoisting, positioning, and attaching the equipment to the supporting structure.
• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.
• Always calculate suspended loads before lifting to make sure suspension components and hardware are used within their respective load limits.
• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which you will suspend the
equipment.
• Use only the recommended brackets with the M8 and M6 installation points.
• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can have hidden
structural weakness.
• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the loads.
Safety Cable
WARNING!:
For any overhead installation, you must use safety cables (not included) attached to the structure and the
loudspeaker enclosure.
1. Install an M6 threaded closed eyebolt (included) into one of the unused M6 threaded inserts on the back of the enclosure.
2. Attach one end of the safety cable to the support structure, and the other end to the eyebolt on the loudspeaker enclosure.
IMPORTANT:
All eight threaded inserts must have fastening hardware (screws or eyebolt) securely installed. The insert holes are open
into the enclosure. If a hole is left open it creates an air leak and the performance of the loudspeaker will be compromised. If the
hardware is not securely installed it may rattle and/or fall out.
