Left, Center & Right Channels

• Place the left, center and right speakers from 1-2 feet (3060 cm) in front of the video screen, anywhere from 6 feet to 10 feet (2–3 m) apart , with the center channel speaker as close to midway between the left and right speaker s as possible.

• Place the left & right speakers at lea st 2 to 3 feet (60–9 0 cm) away from the side w alls.

• The main listening position should be bet ween 4 and 10 fee t (1.2–3 m) away from the sp eakers.

• If necessary, pivot the tweeter and the woofe r of each spe aker towards the listening positi on to maximize the soundstage. The pivoting feature is avail able only on the Original Series Medium Round 625R, 62 4R, 623R, 622R , and 621 R speakers. The adjustable thre e-position tweeter swit ch is available on the 625R, 624R, 623R, and 623R T L.

OR IGINAL SERIES MEDIUM ROUND SPEA KERS

Left & Right Surround Speakers (5.1-Channel System)

Locate th e left and ri ght surround speakers on the ceiling between 2 and 6 feet (.6 - 2 m) beh ind the lis tenin g p ositi on. The speakers sh ould be between 6 and 10 feet (2 - 3 m) apart. Since the surround spea kers a re usually called -upon to cre ate diffuse effects like the sound of win d or rain, they can be located close to walls without adversely affecting sound quality.

Use Figure 1 as a gui de.

Left & Right Surround and Surround Back Speakers

(7.1-Channel System)

• Left & Right Surround Spe akers: Place the left and right surround speakers directly to the sides of the list ening position, betwe en 6 feet and 10 feet (2 - 3 m) apart. The speakers can be placed close to the si de wal ls.

• Surround Back Spea kers: Plac e the surround back speakers between 2 and 6 feet (.6 - 2 m) behi nd the liste ning position. The surr ound back spe akers should be closer together than the left an d right su rroun d speakers -- between 3 an d 6 feet (1 - 2 m) apart. Like the lef t and right su rround speakers, the surround ba ck speakers can be located close to walls without adversely affecting sound quality.

• You can crea te a more diffuse, spacious surroun d effect by pivoting the tweeter and the woofer towards a wall or window, away from t he listeners. This fe ature is availa ble only on the Original Series Medium Round 625R, 624R, 623R, 622R, and 621R spe akers. T he adjustabl e three- position tweeter swit ch is available on the 625R, 624R, 623R, and 62 3R TL.

Wire Gauge

Extra resistance in the spe aker wire can make speakers sound less dyn amic and redu ce definition of the bass frequencies. In extreme case s, it can even atten uate high frequenci es. Also, amplifier power is wasted in wire with extra r esist ance, reduci ng your system’s maximum output level.

To prevent degrading sound qua lity, the total wire resistance should be less t han 10% of the speaker’s imp edanc e. This means that for an 8-ohm speak er, the tota l resi stanc e of the wire should be less than 0 .8 ohm s.

Refer to the table be low to select the proper wire g auge for your system.

Preparing the Installation Location

All Sonance speak ers are designed to be rela tively insensitive to variation s in enclosure volume. To achieve the ul timate performance from y our speakers, a sectio n of the ceiling bay can be partitioned to form a back box. Bui lding such an enclosure will create a dram atic imp rovement in your speaker s’ bass performance and power handling.

Ideal internal back box volume requirements:

0.62 ft³ (.0175 m³) overall size

Insulating the Ceiling Cavity

You can reduce sound transmission to adjacent rooms and further improve speaker pe rform ance by inserting a sh eet of unfaced fiberglass insulation over the back of the speaker.

To reduce noise prod uced by un supported drywall, install fiberglass insulation in the ceiling bays adjacent to the speaker location.

OR IGINAL SERIES MEDIUM ROUND SPEA KERS

Optional Retrofit Enclosures

For insta llations wher e it isn’t possible to partition the ceiling bay to form a back box (such as when you’re retrofitting the speakers into an e xisting ceiling), you can effectively reduce sound transmission into adj acent rooms by fitting the speakers with the optional Medium Round Retrofit En closure (part# 92343) or t he Medi um Roun d 6½” Woo den Enc losure (part# 91688). These enclosures are designe d specifically to be use d wit h these spe akers , and will noticeably reduce sou nd “spillover” from the rea rs of t he speakers into adjacent rooms and spaces.

Installing the Speakers

Before Installation: New Construction

For ins talla tions in new constru ction , Sonance recommends using a Flex Bracket (part# 9233 7) to reserve a loc ation for the speaker. The Flex B racke t has perforated wings that can be positioned at any ang le around the bracket, and is nailed or screwed to the studs. This serves as a guide for the drywall er so that t he speaker ho le will be in the desired locat ion once the drywall is installed.

Before Installation: Retrofit

1. Dete rmine the locati on for the speaker (see Speaker Pla cemen t on page 1).

2. Perf orm an obstruction survey to be certain that the re are no studs, conduit, pipes, heating ducts or air returns that will interfere with the speaker.

3. Moun ting s pace r equir ements:

• Medium Round speakers: 8¼” (210mm) diameter cut-out;

4¾” (121mm) depth within the mounting cavity.

• Medium Round ThinLine

cut-out; 3

4. Posi tion the included cutout template wher e t he speaker is to be located and pencil an o utline on th e ceil ing.

• If you are u nsure about o bstructions, drill a small hole in

the center of the ou tline and insert a coat hanger wire into the hole to fe el-around for possible obstructions.

5. Cut the moun ting hole using a keyhole or drywall saw, and run the speaker wires from the moun ting hole to the ampl ifier location.

/32” (77mm) depth within the mounting cavity.

mounting

3. Stri p ¼” - ½” (6mm - 12mm) of insulation fr om e ach speaker lead. Twist the strands or tin the exposed wire with solde r to ensure that there are no stray stran ds. (Stray s trand s that touch each other can cause a short circuit that can damage the amplifier.)

4. The speaker’s connector posts are spring-loade d. Push the top of each connector p ost down to open the conne ctor and insert the exposed wires into the holes in t he pos ts.

• The spea ker’s positive post is labeled with a r ed dot; the

negative post i s lab eled with a bla ck dot. Connect the speaker wire to the termina ls on the speaker. Doublecheck that you co nnected amplifier “+” to spe aker “+ ” and amplifier “–“ to speaker “–“.

5. Make s ure all the Roto-Lock clamps are in the full clockwise position so that they are tucked within the mounting hole’s border. Insert the speaker into the hole in the ceiling. The Roto-Lock system can accomm odate a maximu m ceiling material thickness of 1¼” (32mm).

• The FastMount tabs wi ll pre vent the speaker from falling out

of the mounting hole, allow ing the installer to let go of the speaker to pick up t ools o r othe r item s (see Figure 4).
