Characteristics

Remarkably powerful engine with low distortion

• To ensure the RSS265HE-22 maintains precise control over the diaphragm at high excursions, it requires an incredibly powerful motor. A stack of three high-energy Y-35 ferrite magnets provides the necessary power while allowing enough clearance for the voice coil to move without touching the back plate.A copper ring and thick aluminum sleeve help minimize stored energy and reduce inductance as the coil passes through the motor. Thanks to this massive motor assembly, the RSS265HE-22 is able to produce extremely low distortion and precise response, even when driven to the limits of its 50mm peak level.

Amazing resilience with low power compression

• The diaphragm is driven by a large 3" diameter voice coil wound on a thick aluminum backing that can dissipate enough heat to handle up to 800 watts RMS. A spiral gap in the bobbin minimizes the eddy currents induced in each conductive bobbin to further reduce inductance and distortion. Ventilation through the voice coil backing and pole piece provides adequate airflow over the coil while minimizing turbulence to allow for quiet operation at high excursion. Additionally, the copper ring and aluminum sleeve improve heat transfer to the pole piece and magnet assembly, dissipating heat from the coil more efficiently. All of this gives the RSS265HE-22 the ability to reliably handle tons of power without experiencing significant power compression, even when pushed hard for extended periods of time.

Optimized suspension for maximum linear stroke

• To accommodate the 25mm Xmax, the RSS265HE-22 required a flexible suspension that would allow linear movement to keep the voice coil centered even when driven beyond the limits of excursion. A custom-machined high-roll surround provides a consistent surface and allows incredible excursion without cramping or deforming. Two progressive spiders with integrated flitter cable support the diaphragm and voice coil. The spiders are optimized to limit movement once the driver reaches Xmax to avoid catastrophic damage during excessive dynamic peaks. Additionally, the spiders have plenty of space between them to center the coil in the tight magnet gap. Every aspect of the RSS265HE-22's suspension has been designed to reliably accommodate extreme excursions without significant distortion.

Aluminum membrane and dust cap... a tradition of the Reference series

• To visually match the other subwoofers in the popular Reference series, the RSS265HE-22 uses a rigid, anodized aluminum cone and dust cap. The cone is significantly thicker to withstand the force exerted by such a powerful motor and to increase mass for low Fs. Thanks to the rigidity and natural damping properties of aluminum, any cone breakup is pushed well out of the passband, giving the RSS265HE-22 an exceptionally flat frequency response, even in the mid-bass and lower midrange. In addition, aluminum is an excellent heat conductor, turning the entire cone and dust cap into a large heat sink, effectively dissipating heat away from the voice coil, further controlling power compression.

Incredible flexibility for powerful bass in any system

• The specifications of the RSS265HE-22 have been tuned to ensure that it can be used in a wide range of situations.The enhanced bass extension makes it ideal for use as a subwoofer in home audio and theater systems. Because the RSS265HE-22 requires only an extremely small enclosure, it is also an excellent choice for use in high-output car audio systems. In addition, the two 2-ohm voice coils allow stereo 2-ohm or mono 1-ohm wiring configurations when connecting to high-current amplifiers in car audio and professional audio for maximum power. For home audio applications, the voice coils can easily be connected in series to achieve a common 4-ohm load and increase compatibility with amplifiers. All Reference Series HE drivers are designed to provide amazing bass reproduction with incredible power, impact and detail.
