Pioneer Debuts Digital Bass Control Technology to Improve Bass Quality and Performance in the Car

Active Add-on Subwoofer First to Integrate Proprietary Technology

LAS VEGAS–(BUSINESS WIRE)–#CES2017CES BOOTH #3902 – Pioneer Electronics (USA) Inc. today introduced
the TS-WX70DA active add-on subwoofer, designed to improve the audio of
virtually any vehicle’s sound system. The model features Digital Bass
Control, a new proprietary technology developed by Pioneer to control
frequency response and increase the performance of the subwoofer system
in the car. Users have a choice between two selectable bass modes, Deep
and Dynamic, created to match and enhance their listening preferences.
Despite its shallow 3-3/4” height, the TS-WX70DA
produces impressive and heavy bass thanks to the system’s combination of
Pioneer’s Digital Bass Control, efficient 200 watt class D amplifier,
two 6-1/2 inch dual voice coil (DVC) subwoofer drivers, and a remarkable
back-loaded horn enclosure design.

“For most consumers, the most significant car audio upgrade starts with
more bass because environmental interference such as wind and tire
noises mask low frequencies. Adding a subwoofer to an existing system
can instantly improve the in-car listening experience,” said Ted
Cardenas, vice president of Pioneer Electronics (USA) Inc. “The
TS-WX70DA is a great option because it incorporates unique engineering
solutions to generate the same powerful bass and impressive sound as a
traditional active subwoofer, while minimizing its physical size and
therefore maximizing the vehicle’s storage space.”

Vehicle interiors are complicated physical spaces with a number of
variables that can affect the frequency response of a car audio speaker
or subwoofer. Soft materials such as carpet and cloth absorb sound
waves, while hard materials like glass, plastic and leather reflect
them. The proprietary Digital Bass Control technology allows Pioneer’s
engineers to optimize each component of the TS-WX70DA as a system in
order to achieve maximum performance for the automotive environment. Two
selectable listening modes, Deep and Dynamic, provide further system
optimization, specially tuning the output to complement various musical
styles. Deep bass mode is tuned for jazz and classical genres,
emphasizing the deep frequencies of the lowest octaves and providing a
more responsive and impactful sound. Dynamic mode reinforces the upper
sub bass frequencies to produce an immersive and powerful sound
characteristic, perfect for modern popular music such as EDM and hip-hop.

The TS-WX70DA’s back-loaded horn enclosure produces a more uniform and
higher SPL output when compared to traditional acoustic suspension
(sealed) and/or bass reflex (ported) designs. A back-loaded horn is a
dimensionally increasing acoustic wave guide designed to reduce physical
air resistance and decrease the potential for peaky acoustic output
caused by unwanted standing wave resonances. Although complicated to
engineer and construct, a properly designed back-loaded horn enclosure
results in maximized acoustic efficiency and wide frequency response.

The thin and flat enclosure offers installation flexibility; designed to
easily drop into the hatch or trunk area of most popular vehicles, the
TS-WX70DA measures 33-1/2 inches wide x 12-3/4 inches deep x 3-3/4
inches high. The rugged construction and durable vinyl covering protects
the unit from damage and allows even heavy items such as luggage to be
placed directly on the unit. The TS-WX70DA also includes a wired remote
for direct control of audio adjustments and settings for the powered
subwoofer. Volume, bass mode, gain control, frequency response, and
phase can easily be adjusted with just the press of a finger.
