Balanced Isolator Circuit
Prevents ground voltage flows from interfering with the signal. Pioneer
improved existing designs by separating the left and right channel
grounds. This puts each channel’s signal wave in phase, which helps
cancel noise components within the grounds. The output is cleaner, with
less interference.
Class-D Amplifiers
Class-D amplifiers require less electrical current and produce less
distorting heat, while 67 % of the power supply is transferred into the load.
A digital signal is generated and filtered through the Low Pass Filter. The
power output FETs ensure more efficient operation, and the design is more
compact thanks to a smaller heat sink. The final result is undistorted and
clear sound.
DMOSFETOutput Section
A DMOSFET output section utilises a high-density circuit layout to reduce
line impedance and maintain stability. Switching noise is eliminated,
resulting in enhanced high-frequency range performance and improved
linear response.
Input Level Control
Level Control adjustment is provided to match the amplifier’s input with the
source unit’s output. Proper adjustment ensures less noise and distortion.
Link Top
Amplifiers with “Link Top” are equipped with output terminals for
convenient, efficient, low noise connection to an additional amplifier
driving a subwoofer or to create a multi-channel speaker system.
Low Impedance Load Capability (High Current)
Refers to power amplifiers that provide 1 – 1/2 times the power output of
standard 4 Ω operation at 2 Ω. Since they have the power to drive more
speakers, these amps also increase system flexibility by enabling the
hook-up of multiple pairs of speakers.
MOSFET Output Devices
MOSFET Output devices offer significant advantages over traditional
bipolar devices. Faster switching enhances acoustic realism and keeps
sound reproduction crystal clear. And with a higher thermal stability,
performance is optimised at peak operating temperatures.
PWM Regulated MOSFET Power Supply
During the process of DC-to-DC step-up transforming, the voltage at the
secondary winding must be kept stable despite voltage fluctuations or
loads fluctuations during windings. Pioneer’s PWM (Pulse Width
Modulation) power supply design maintains stability between primary and
secondary windings, and uses a MOSFET to switch the power supply on
and off very quickly in response to input. This translates into cleaner
output with less distortion.
Screw-Type Terminals
Pioneer uses Screw-Type terminals for the speaker connections as well as
the power and ground connections. These terminals make a more reliable
connection and allow the use of larger gauge wire for improved
performance.
Speaker Level Input
This allows a Pioneer amplifier to be connected to an OEM radio without
requiring costly add-on adapters. The added flexibility allows your Pioneer
amplifier to be a part of your system as it grows and expands.
Variable Bass Emphasis
Allows bass frequencies to be boosted for each equipped amplifier. This
allows the installer/user to set the optimal bass level for the speakers
connected to that individual amplifier, allowing the user to best utilise the
headunit’s tone controls for all speakers in the system.
3-D Magnesium Hybrid Cone
The E-Motion Series 3-D Magnesium Hybrid Cones produces purest,
accurate sound with the most possible power through the use of an alloy
of Magnesium and Aluminium.
3-layer Fibre Woven Radial Surround
The innovative patent-pending 3-layer Fibre Woven Radial Surround
consists of two outer layers and one inner layer of interwoven fibre. This
results in an extremely durable and resilient surround which improves the
high power capability.
ADMG (Aero-Dynamic Magnetic Gap)
Each pole piece and top plate of the ADMG has an air channel in a narrow
magnetic gap, which effectively reduces physical resistence.

Aluminium Die-Cast Basket with Bottom Hold Structure
Pioneer’s new aluminium die-cast basket securely supports the motor,
and provides excellent damping characteristics to attenuate vibrations
quickly and prevent distortion.
Aramid Fibre Cone Woofer
The woofer of the TS-W12PRS, TS-M7PRS, TS-C1700R and TS-C1300R was
meticulously designed to reproduce real strings and vocals with less
distortion. Thanks to the Aramid Fibre Composite Cone, you can expect
accurate, smooth sound from mid-bass to upper midrange frequencies.
Bass Reflex
A loudspeaker design in which the sound waves generated by the driver’s
rear surface are allowed to pass through a port in the enclosure to
reinforce bass response. This enables smaller drivers to offer increased
bass response with less power.
Butyl Rubber Edge
The rolled edge where the speaker cone meets the frame, is made of a
specially blended, highly durable and moisture-resistant compound.
Butyl Rubber keeps the cone moving in a linear direction and stops the
cone from vibrating. This leads to less distortion and superior frequency
response.
CCAW (Copper-Clad Aluminium Wire) Voice Coil
Aluminium wire is lighter than conventional copper wire. When used as a
voice coil material, larger gauge aluminium wire can be used to increase
maximum input power and to extend bass response. A copper coating
over the aluminium enables sure soldering contact and wide frequency
response.
Conex Damper
The damper guides the speaker cone and voice coil as it moves back and
forth during use. While typical dampers are made of cloth, on many
models Pioneer uses Conex. This special material provides increased
rigidity, longer travel and improved moisture resistance.
Conical Dome Technology
The Pioneer IMPP cone woofers give smoother low to upper midrange
reproduction and high rigidity through the use of highly Crystallised
Polypropylene. The integration in the cone of conical domes (Bass Bullets)
results in lower distortion, richer bass sounds and increased cone rigidity.
Crystalline IMPP Cone
This material with high young modulus and high propagation rate makes
the cone more rigid and improves the transient response, resulting in
accurate sound.
Double Damper
A damper supports the speaker cone and guides the cone as it moves
back and forth during use. By using two dampers instead of one in many
of its speakers, Pioneer has greatly improved linearity over the entire
frequency range of the speaker.
Dual Ceramic-Coated Voice Coil
The ceramic coating superbly insulates the voice coil wire, preventing
short circuits due to overheating and drastically improving reliability;
meaning double power handling capacity of a conventional voice coil.
Dual Voice Coil
The flexible wiring configuration of the Dual Voice Coil subwoofers when
used in combination with a low impedence compatible amplifier, can give
an even bigger and more powerful bass reproduction capability.
Easy Connector
Most 17 cm and 13 cm custom-fit models are equipped with a
handy Easy Connector, making it easier to cable them with
the car’s speaker connectors.
Foamed IMPP
Using a unique foaming process during the injection moulding process,
Pioneer’s IMPP speaker cones feature lighter weight and increased
rigidity for improved linearity, decreased distortion, improved bass
performance and clarity.
Foamed PPC (Pearl Polycarbon) Diaphragm
The Pioneer foamed PPC diaphragm is light-weight yet rigid, resulting in
an improved low-mid transient response and smoother midranges,
opening the sound character.
Glass-Imide Voice Coil Bobbin
Many Pioneer speakers utilise a voice coil whose cylinder is made from a
woven fiberglass material bound by a polyimide resin. This Glass-Imide
material has much higher heat resistance, which translates into higher
power handling capability for the speaker and less distortion.
High-Power Motor Assembly
The huge motor structure provides more powerful force to move the cone
assembly harder and consequently overcome the tremendous air
pressure resistence.
IMPP™ (Injection-Moulded Polypropylene)
Composite Cone
Pioneer uses a special injection moulding that ensures
uniform cone thickness for superior linearity and clarity. Pioneer’s
“Composite” technology guarantees the perfect mix of polypropylene and
carbon-fiber, graphite and other materials to optimise the speaker cone
for its specific application (woofers, midranges, or tweeters, etc.).
Interlaced Fibre Reinforced IMPP Cone
Pioneer’s patent-pending IMPP cone utilises a composite blend of
interlaced long fibres (e.g. carbon fibres). This cone is extremely rigid yet
lightweight, for low distortion and powerful bass at high sound pressure
levels.
Linear Power Response
With no roll to restrict the cone’s movements, this innovative system
mimics a finely tuned precision piston, smoothly moving the speaker cone
up to a higher level than ever. And thanks to its unique edgeless
diaphragm, there is no stress or distortion around its diaphragm.
Neodymium Magnet
Neodymium has a high magnetic flux density. It is about 7.5 times
stronger than a standard magnet and allows Pioneer speaker designers to
make a tweeter that is smaller and has reduced distortion as compared to
a model using a standard magnet.
Overhung Surround
By extending the wide-roll surround over the typical gasket area, this
design provides 22 % more cone surface than traditional surround
designs. The increased surface moves more area and achieves higher
sound pressure levels.
Power Blades
The Pioneer Magnesium Hybrid cone woofers give smoother low to upper
midrange reproduction and high rigidity. The integration in the cone of
Power Blades (protrusions) results in lower distortion, richer bass sounds
and increased cone rigidity.
Pulp Drive Cone
Paper pulp is used in the E-motion Series speakers to form a drive cone
on the backside of the Magensium Hybrid Cone. Very light material that is
resistant to longitudinal strain, pulp eliminates additional vibration and
distortion. This results in a smooth, purer sound.
Separate Component Speakers
Speakers, such as woofers, midranges and tweeters, that reproduce only
certain frequencies. Component Speakers not only reproduce the audio
signal more accurately, but also increase the listener’s control over the
audio signal.
Strontium Magnet
A very powerful magnetic material which has a greater magnetic force
field than a ferrite magnet. Strontium magnets improve efficiency and
power handling capabilities. This enables engineers to build a much
smaller magnet, and consequently a thinner speaker to fit in areas with
limited mounting depth without compromising sound quality.
Swivel Mount Tweeter
The swivel mount tweeter offers the best of all installation possibilities.
Featuring a specially designed flush-mount cup, this mounting system
allows the tweeter to be angled in any direction for optimum imaging and
placement.
Titanium Dome Tweeter
The Titanium Dome driver of the E-Motion Speaker Series has a pure
titanium diaphragm. Titanium produces crystal clear high notes with
minimum distortion and ensures a smooth woofer to tweeter transfer
using the maximum power possible.
VCCS (Voice Coil Cooling System)
VCCS brings high power to the Pioneer subwoofers.
The Voice Coil Cooling system takes the heat away
from the new 4-layer voice coil using a heat resistant, highly conductive
aluminium bobbin. Plus, extra slits in the bobbin reduce eddy currents
while radiating the heat. This results in distortion-free, tonally accurate
sound.
