OPTIONAL ACCESSORIES

FlexBracket - part number 91922

Acoustical Enclosure - part number 91921

Plastic template to reserve a hole in new construction. Designed to be used with the Flexbar mounting system.

A 1/2" medium density fiberboard enclosure designed specifically for the Ellipse speakers.

7 - CHANNEL HOME THEATER PLACEMENT

Try to apply as many of the following suggestions when using four Ellipse SUR speakers as your surround speakers.

Front surround speakers can be located directly to the sides of the seating or approximately two to three feet in front of the seating for better integration with the left, center and right speakers. The speakers should be oriented so the coaxial drivers face the front and rear walls of the room.

Rear surround speakers should be located approximately four to eight feet behind the seating and the speakers should be separated six to ten feet apart. The speakers should be oriented so the coaxial drivers face the left and right side walls of the room.

4 to 8 feet

8 to 12 feet

6 to 10 feet

Sonafill in-ceiling - part number 91928

Sonafill is a retrofitable acoustical treatment for that virtually eliminates the noise produced by resonating drywall and dramatically improves mid-bass sound quality

5 - CHANNEL HOME THEATER PLACEMENT

The ideal location for the Ellipse SUR is two to four feet behind the listening position with the speakers separated approximately eight to twelve feet.

The speakers should be oriented so the coaxial drivers face the front and rear walls of the room.

8 to 12 feet

Placement with four surround speakers

ALTERNATIVE PLACEMENT OPTIONS

In many installations the main seating will be against the rear wall of the room. In this type of room we suggest locating the speakers approximately two feet from the rear wall and spaced from ten to fifteen feet apart.

Locating the speakers in this way will provide a more diffuse surround presentation.

10 to 15 feet

Placement with two surround speakers

Alternative placement with two surround speakers

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 SUR 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.

Ellipse FlexBracket

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.
