Surround Speaker System

INTRODUCTION

We designed the SR.5 for maximum placement flexibility.

You can mount the SR.5’s virtually anywhere around your

listening room and still achieve strong envelopment. The

SR.5’s use a unique bipolar radiating pattern for dozens

of unique placement options.

ﬁOn side walls

ﬁOn back walls

ﬁOn the ceiling

Most importantly, the SR.5’s do not require symmetrical

placement. You can place one unit on a side wall, and the

other on the ceiling or back wall.

For Use With All Home Theater Formats

The SR.5’s meet the demanding sonic requirements of

digital 5.1 formats.

ﬁTheir dispersion pattern combines an

optimal blend of diffuse sound, with just

enough directivity for precise off-screen pans.

ﬁThey extend from 70 to 20,000Hz, capturing all

surround information in this range.

ﬁThey play loud enough to fill a typical

listening room at theater volume.

ﬁTheir power response matches the Snell K.5

Monitors and E.5 Towers for seamless front-to-

back pans.

FEATURES OF THE SNELL SR.5 SURROUND

Mounts to Walls or Ceilings

Our unique locking bracket keeps the SR.5 securely

mounted to walls or ceilings. One person can install

the SR.5 simply and securely.

Connectors

Five-way gold-plated binding posts allow quick con-

nection to speaker cables and connectors. The

recessed area on the back of the cabinet accommo-

dates wire slack for neat installation.

Hand-Tuned Crossover

The bipolar network is optimized to provide a smooth

and flat power response. Each crossover is tuned by

our technicians to ±0.5dB of the Master Reference,

assuring predictable performance in your home.

Angled Cabinet Design

The angled cabinet of the SR.5 projects sound for-

ward and backward in a “dog-bone” pattern. This wide

sound field gives you dozens of placement options.

Speaker Elements

Two 3 1¼2" (89mm) extended-range drivers are

responsible for frequencies between 400Hz and

20kHz. One omnidirectional 5 1¼4" (135mm) bass

unit handles all frequencies from 70Hz to 400Hz.

Family Sound

The SR.5’s are tuned with a flat, optimized power

response, to match the spectral balance of Snell front

speakers.

Place the SR.5 to the side of the listening area. If the listening area

is against a wall (for example, if your couch is placed against a back

wall), place the SR.5 to the side of the couch, leaving at least a 12"

clearance between the SR.5 and the back wall.

When placing the surround behind your listening area, keep it as

close to the side wall as possible—but no closer than 12" (30cm).

HOW TO PLACE YOUR SR.5 SURROUNDS

Side Wall Placement Back Wall Placement

Determine Room Placement

Proper room placement is perhaps the most important factor contributing to home the-

ater sound quality. Take a few minutes to place your speaker systems correctly to ensure

they sound their best.

Home Listening Room Placement

Follow these guidelines for proper placement:

Height: Place the surrounds at least 5' (2.4m) from the floor, yet 12" (30cm) from the

ceiling. Higher is better.

Boundaries: Keep the surrounds at least 12” (30cm) away from an adjacent wall or

large obstacle.

Placement Options: Each surround can be placed independently to accommodate your

room. The following diagrams illustrate these placement options:

ﬁOn side walls ﬁOn back walls ﬁOn the ceiling

Screening Room Placement

Snell speaker systems are often used in professional dubbing studios. Follow these

recommendations for critical screening room applications:

Height: At least 8' (2.4m) from the floor, or 18" (46cm) down from the ceiling.

Placement: On the side walls, centered to the listening area.

Boundaries: At least 3' (1m) from back walls.

Coverage Area: Use one surround speaker system for every 3 rows of seats

(approximately 10' between surround speakers).

One or both surrounds may be placed on the ceiling. If the viewing area is in or near a corner, the SR.5’s may be placed

to either side on the adjacent wall or ceiling.

Connecting with Bare Wire:

Insert bare wire into holes and tighten.

Connecting with Banana Plugs, Spade Lugs, or Pins:

The binding posts accept standard banana plugs and pins,

and can accommodate spade lugs up to 5¼16".

Connecting to a Surround Processor

Select the SMALL or NORMAL surround setting on your receiver or processor. This routes

all bass information (typically below 120Hz) from the surrounds to your subwoofer.

Match the Sound Levels of Each Speaker

Your home theater system most likely includes a test signal that simplifies level match-

ing. Refer to the instructions provided with your surround sound electronics.

Receiver or Amplifier

Warning! To prevent

electrical shock, always

switch off the amplifier

or receiver when making

connections to the

speaker system.

WALL OR CEILING MOUNTING YOUR SR.5 SURROUNDS

Please Note:

Installation of surround speakers requires a thorough understanding of construction tools and procedures. We recom-

mend you consult a knowledgeable installer if you are unsure of the physical properties behind your wall or ceiling.

Mounting the Bracket When Using the Machine

Screws and Toggle Wings

1. Drill two 9¼16" (13mm) holes using the bracket as a

template. If running wires behind the wall, make a hole

for them as well.

2. Insert the machine screws through the bracket and

thread onto the toggle wings before penetrating the wall.

3. Level the bracket and tighten the screws.

4. Connect the wires.

5. Place the SR.5 on the bracket and slide down until you

hear a locking “click.”

3" #10 machine bolts

toggle wings

Drill two 9¼16" (13mm)

holes for the toggle wings.

Wires connect to terminals on

back of SR.5. Tuck excess

wire into the recess on back

of the speaker.

Level the bracket before

hanging the speaker.

Place the SR.5 on the

bracket and slide down until

you hear a locking “click.”

Place felt bumpers on back

of the SR.5 to protect your

wall or ceiling.

Mounting on Drywall, Paneling, or Other Hollow

Surfaces

Use the supplied 3" #10 machine screws and toggle wings.

The toggle wings require a 9¼16" (13mm) hole.

Mounting on Wood and Other Solid Surfaces

Use the supplied 2" #8 particleboard screws.

Mounting on Masonry, Adobe, and Similar Surfaces

Consult a knowledgeable installer about proper hardware.

You will obtain best results with #8 screws.

LISTENING LEVELS AND

POWER HANDLING

The power recommendation for the system assumes you

will operate the amplifier in a way that will not produce

distortion. All speakers can be damaged by a modest

amplifier if it is producing distortion. If you hear a gritty

noise or other signs of strain, turn down the volume.

Prolonged or repeated operation of your speakers with a

distorted signal can cause damage that is not covered by

the warranty.

HOW TO CARE FOR

YOUR SR.5’S

Cabinet

Your speaker system has been hand-sanded and finished

with either a black or white paint.

ﬁUse a soft terry cloth towel slightly dampened

with water or a mild detergent. The towel should

be just damp enough to wipe the surface clean

without leaving a trail of moisture.

ﬁDo not use abrasive cleaners or any cleaner con-

taining chemicals harsher than those found in

glass cleaner.

Grille Cloth

ﬁYou can remove the grilles from the speaker sys-

tem and gently vacuum to remove dust.

When ceiling mounting, follow the same installation

procedures as previously outlined.

Place felt bumpers on

back of the SR.5 to

protect your ceiling.
