The low-to-mid frequency driver in the LSS-161 comes from the development of DD’s C Series 6.5″ woofer, which excels in both infinite baffle and bass reflex designs. Its combination of low moving mass, tight magnetic control, and linear suspension allows for accurate tracking of transient signals.

The curvilinear, shallow composite cone uses an asymmetrically woven carbon-and-glass fibre structure that provides high rigidity while maintaining natural damping to suppress upper-band ringing modes.

This ultra-light cone is paired with an NBR rubber surround that is flexible, durable, and light enough to support high sensitivity while further reducing edge resonance.

The bifilar-wound voice coil lowers moving mass and improves sensitivity and power handling, while a shorting ring in the motor system reduces inductance for low distortion performance.

The high-frequency driver in the LSS-161 is based on the C Series 20mm broadband tweeter, a true marvel of current material science and acoustic design, engineered for exceptional bandwidth and transient precision. Its magnesium-aluminum alloy diaphragm is only 0.035 mm thick, combining extreme rigidity with very low mass to extend response and speed. The diaphragm is suspended by a carefully shaped silk surround that maintains stability across a wide operating range, enabling usable bandwidth from roughly 600 Hz to over 40 kHz. A dual-magnet neodymium motor with copper shorting rings maintains a stable magnetic field, reduces inductance modulation, and lowers distortion. The rear cavity back chamber and front waveguide of this tweeter have been tuned specifically for the LSS-161 application.

Merging the soundfield into a cohesive flow is a phase stable crossover design utilizing high performance parts chosen for minimal electrical signature, terminated by gold plated, pure copper binding posts.

The state of the art C Series components and LSS-161 bass reflex cabinet were designed in tandem to ensure simpatico performance. The low velocity port design has an extremely large cross section area that reinforces the lowest bass frequencies without turbulence robbing efficiency, coupling smooth bass extension effortlessly into the room. The inner port structure is also designed to internally brace the cabinet walls into a singular stiff structure. The internal shape is designed to break up standing waves that could smear midrange frequencies.

The double baffle serves multiple functions, rigidly holding the acoustic drivers eliminating vibrational losses, merging the acoustic responses of the drivers while the double step reduces edge diffraction at the cabinet boundaries.

The furniture grade finish is a natural walnut and black lacquer combination offering a timeless design enhancing any living area, desktop or monitor console. The cabinet bottom is equipped with screw in gold plated feet complete with scratch protection discs and the cloth grill is suspended by invisible magnets.
