OPTIONAL ACCESSORIES

FlexBracket - part number 91922

Designed to be used with the Flexbar mounting system.

Plastic template to reserve a hole in new construction.

RECOMMENDED PLACEMENT CONTINUED

Proper placement of the Ellipse LCR is critical for maximum performance. Try to apply as many of the following recommendations in your installation.

The speakers should be located from eight to eighteen feet from the listener. The minimum recommended spacing from speaker to listening position would be approximately 6 feet in a room with eight foot ceilings. The height and size of the television will largely determine this distance. Keep in mind that if the television is placed at eye level and the speakers are installed less than six feet in front of the listening position the picture and sound could seem very disconnected.

If possible the speakers should be located a minimum of three to four feet from the front wall this is the wall the television is on.

The left and right speakers should be separated approximately eight to twelve feet apart with the center speaker placed as close to the middle as possible. The Sonic Eye on all three speakers should be pivoted toward the listening position.

8 to 18 feet

dramatically improves mid-bass sound quality

RECOMMENDED PLACEMENT

The design of many homes today leaves little space for box or in-wall LCR speakers. The use of in-ceiling LCR speakers has become quite common in the last few years. Most of these installations have used speakers not well suited for this purpose. The Ellipse LCR was specifically designed to solve this problem.

The most important c onsideration when using in-ceiling LCR speakers is maintaining good cohesion between picture and sound. As a general rule you should try to install the speakers no more than 4 to 6 feet away from the top of the television. In a room with 8 foot ceilings and using a rear projection or large tube television this should be very easy.

Using the following recommendations will insure your installation achieves maximum performance from the speakers.

3 to 4 feet

8 to 18 feet

8 to 12 feet

WIRE GAUGE AND QUALITY

The total wire resistance should be less than 10% of the speaker impedance. If using an 8 ohm speaker, your total wire resistance should be no more than 0.8 ohms.

In simple terms, the extra resistance from the wire will have a very negative affect on the sound quality of the speaker. The sound can be less dynamic, definition of bass frequencies can be reduced, and in extreme cases, the high frequencies can be attenuated. Amplifier power is also wasted in the wire, reducing the maximum output level of the system.

Please refer to the following chart when deciding on the appropriate wire gauge for your installation.

The Sonafill System

PREPARING THE INSTALLATION LOCATION

All Sonance speakers are designed to be relatively insensitive to changes in enclosure volume. To achieve the ultimate performance from the Ellipse LCR speaker, a section of the ceiling bay can be sectioned off to form a back box. Building this enclosure will create a dramatic improvement in the quality of bass response and power handling.

Ideal Back box volume:

Insulating the ceiling cavity

Speaker performance can be enhanced by insulating the cavity with fiberglass insulation.

When installing speakers in a ceiling, it is best to lay a sheet of unfaced fiberglass insulation over the back of the speaker.

To further improve the sound quality, install insulation in the bays adjacent to the speaker location. This will reduce noise produced by the unsupported drywall.

Sonafill

Sonafill is a retrofitable acoustical treatment for loudspeakers that virtually eliminates the noise produced by resonating drywall and dramatically improves mid-bass sound quality. Sonafill also reduces room-to-room noise especially in multi-channel installations where many speakers are installed.

The Sonafill system consists of two pillows and four tiles. Installation is accomplished by first adhering the tiles to the inside of the cavity, then stuffing the two pillows in place behind the tiles.

New Construction

The Ellipse LCR speaker features an integral FlexBar mounting system for quick mounting into ceilings. The Ellipse FlexBracket is only necessary in new construction installations when reserving a location for the speaker is desired.

The FlexBracket will serve as a guide for the drywall installer when cutting holes for in-ceiling speakers. The FlexBracket can be nailed, screwed or stapled to the joists so that the hole is in the desired location once the drywall is installed.

Retrofit

With the FlexBar system, the speaker can be installed directly into existing ceilings. Once the hole is cut and the cable is run, the speakers can be installed in a matter of seconds.

Once you have determined the area you would like to locate your speakers, you will need to do an obstruction survey. Before you cut the hole for the speaker, be certain no joist, conduit, pipe, heating duct or air return will interfere with the speaker.

A cut out template is provided in the packaging of the speaker. Position the template where the speaker is to be located and pencil an outline on the ceiling. If you are unsure about obstructions drill a small hole in the center of the circle and insert a coat hanger into the hole to feel for possible obstructions. If no obstructions are found, proceed with cutting the hole using a drywall saw and run the speaker wires.
