This manual is also suitable for

CA.10WF.2R

Terra CA.10.2S is an all-climate, weather-resistant loudspeaker suitable for both indoor and outdoor use. It features an anodized-ceramic aluminum diaphragm (ACAD) cone for greater clarity, purer sound, and better dynamics, and a magnetic fluid centering system (MFCS) for extended bass, less distortion, and better linearity. The CA.10.2S also has a cation-plated magnet for corrosion resistance, making it ideal for use in harsh marine environments like boats. With its paintable frame and grille, the CA.10.2S can be customized to match any décor.

TERRA TECHNOLOGY & DESIGN

Terra Custom Application loudspeakers use innovative technologies to combine the dynamics of

traditional box speakers with the aesthetic advantages and placement flexibility of in-wall architec-

tural speakers. Terra CA Series speakers sound refreshingly clear and open, and exhibit little sign

of strain at high output levels. You can listen to them for hours on end without the slightest bit of

fatigue. Unlike most in-wall or in-ceiling speakers, the CA Series are weather resistant, allowing for

use on boats, outdoor walls, or in wet indoor locations.

ALL CLIMATE DESIGN

ACAD driver is immune to harsh environments • MFCS eliminates spider degradation and improves

linearity • Cation-plated magnet resists corrosion • Aluminum and stainless steel hardware

• Integral mounting tabs • Paintable frame and grille

ACAD: Anodized-Ceramic Aluminum Diaphragm

One of the founding principles of Terra is that metal is the best choice for a speaker cone. Terra’s

proprietary anodizing method strengthens the aluminum cone and also damps it to minimize vibra-

tion. The result is a cone that’s as light and rigid as possible – two qualities essential for producing

great sound. And unlike ordinary cone materials, ACAD is immune to harsh outdoor environments

and won’t degrade over time.

Greater Clarity

- unmasks the details that distinguish truly musical sound

Purer Sound

- rigid, lightweight cone minimizes distortion, plays loud without harshness

Better Dynamics

- reproduces musical dynamics without strain

More Listenable

- smooth, non-strident sound eliminates listener fatigue

More Reliable

- seamless, one-piece cones will not deteriorate or change characteristics with age

MFCS: Magnetic Fluid Centering System

In a conventional loudspeaker the “spider” – typically a pleated fabric – acts like a spring to return

the voice coil (and the cone) back to its starting position, centered within the magnet’s gap. The

Terra bass driver does away with the spider entirely, instead using a special magnetic fluid in the

gap. This fluid provides the restoring force – in the form of magnetic attraction – needed to guide

the voice coil and keep it centered within the gap. Particularly at high output levels, the greater

precision of the MFCS reduces nonlinearity and also permits longer cone excursion for greater out-

put. And unlike a traditional spider – which is a mechanical device – the Terra MFCS is immune to

harsh outdoor environments and won’t degrade over time. In addition, the magnetic fluid acts as a

heat sink for the voice coil, which helps increase power handling by cooling the voice coil so it can

handle more current.

Extended Bass

- longer cone excursion maximizes bass output

Less Distortion

- voice coil is constantly centered, even at the loudest levels

Better Dynamics

- absence of mechanical resistance speeds transient response

Greater Linearity

- linear damping forces ensure consistent response

More Reliable

- no mechanical parts to deteriorate or fail with age

Cation-Plated Magnet

The magnet in the CA Series is cation-plated, an electroplating process that creates an anti-cor-

rosive protective layer at the molecular level. This allows the CA to be used outdoors, including in

tough marine environments like boats.

ADVISORY

The Terra CA Series loudspeakers are designed for installation in walls or ceilings. If

you are not

completely comfortable

with cutting holes in your walls and fishing speaker

wires through your walls, please hire a professional audio/video contractor. The follow-

ing instructions assume that you are installing into existing wallboard.

AMPLIFIER POWER

Speaker damage most commonly results from UNDERPOWERING the speaker. If you

hear distortion from the speaker, chances are that the amplifier has exceeded its output

capability and is “clipping.” If you hear distortion at loud levels, turn down your amp

immediately! Clipping WILL cause damage to a speaker, and such damage is not cov-

ered under the warranty.

THE “BREAK-IN” PERIOD

You may play your Terra speakers immediately with excellent results. However, subtle

improvement can be expected as the ACAD™ drivers break in after 50 to 100 hours

of operation.

PAINTING

The speaker frame and the grille can be painted with a thin coat of spray paint.

•

Use a thin, flat-blade screwdriver to gently pry up the grille from all sides until you

can grasp it for removal. Take care not to damage the frame as you pry.

•

Applying too much paint to the grille can plug the holes.

•

Mask the speaker assembly so only its frame gets painted.

•

Allow paint to dry thoroughly before handling the speaker.

SPEAKER LOCATION

The diagram below provides placement guidelines for installation in walls. For ceiling

installations the spacing between speakers and from corners is the same.

STEP 1: MARK SPEAKER LOCATIONS

Speakers should be placed between studs, which are typically spaced 16" apart. (If you

are not sure about the location of the studs, purchase an inexpensive “stud finder,” a

magnetic device that indicates stud position by detecting nails.) Try to locate the speak-

ers at least 18" from corners.

Be careful not to locate the speakers too close to electrical switches, outlets, phone

jacks, and ceiling fixtures so as to avoid cutting into their wiring.

Using a level, mark a straight line on the wall or ceiling to denote the bottom edge of

each speaker. Using the supplied cardboard template that is part of this package, trace

the outline of the speaker cutout using the lines you’ve drawn as a reference.

STEP 2: CUT THE HOLES

You will need a utility knife or small saw, and a drill with a 1/4- to 1/2-inch-diameter

bit. Drill holes on the inside corners of the outlines you’ve traced. These holes make it

easier to begin cutting or sawing. Then cut or saw exactly along the paths you’ve traced.

Remove the pieces you’ve cut as well as any insulation that will impede installation.

STEP 3: RUN THE SPEAKER WIRING

Use at least 16-gauge wire. For long runs (100 feet or more) we recommend thicker

14-gauge wire. Run the wiring to the connection point. Leave at least 12 inches at the

cutout for connecting each speaker.

STEP 4: CONNECT THE SPEAKER WIRES

Solder the wire leads to the positive (red) and negative terminals on the speakers. Note

that the R2, S2 and WF models also provide spring clip terminals.

STEP 5: INSTALL THE SPEAKERS (SEE DIAGRAMS BELOW)

Remove the grille to gain access to the mounting screws. Make sure the clamping tabs

on the back of the speaker are in a vertical position, then tilt the speaker assembly

slightly to work it into the hole. DO NOT TIGHTEN THE SCREWS YET.

Tighten the front-panel screws while making sure each speaker is positioned squarely.

TIGHTEN ONLY UNTIL YOU FEEL SOME RESISTANCE. The clamping tabs will rotate into

position and draw the frame in against the wallboard, securing the speaker in place. The

speaker frame is flexible, so it will conform to slight variations in the flatness of the wall.

DO NOT OVERTIGHTEN or you may damage the frame.

STEP 6: RE-ATTACH THE GRILLES

Gently press around the perimeter of the grille to work it back into the frame.
