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.
