Remarkably powerful low distortion motor

 

 

In order to keep precise control of the cone when driven to high excursion, the RSS265HE-22 requires an incredibly powerful motor. A stack of 3 high energy Y-35 ferrite magnets is used to provide the force needed while allowing ample clearance for the voice coil to travel without impacting the back plate. A copper ring and thick aluminum sleeve helps minimize stored energy and lower inductance as the coil travels through the motor. This massive motor assembly gives the RSS265HE-22 the ability to produce extremely low distortion and accurate response even when driven to the limits of its 50 mm peak-to-peak excursion.

 

Amazing power handling with low power compression

 

Driving the cone is a large 3” diameter voice coil wound on a thick aluminum former that is capable of dissipating enough heat to handle up to 800 watts RMS. A spiral spit in the former minimizes the eddy currents that are induced into any conductive former, to further lower inductance and distortion. The venting through the voice coil former and pole piece delivers ample airflow across the coil while minimizing turbulence to allow quiet operation when pushed to high displacement. In addition, the copper ring and aluminum sleeve improve heat transfer to the pole piece and magnet assembly, more efficiently absorbing heat away from the coil. All of this gives the RSS265HE-22 the ability to reliably handle tons of power without suffering from significant power compression, even when pushed hard for extended periods.

 

Optimized suspension for maximum linear stroke

 

In order to accommodate the 25 mm Xmax, the RSS265HE-22 required flexible suspension that permits linear movement to keep the voice coil centered even when driven beyond the limits of excursion. A custom tooled high roll surround maintains surface area and allows an incredible amount of travel without tightening up or distorting. Dual progressive spiders with integrated tinsel leads support the cone and voice coil. The spiders are optimized to begin restricting movement just as the driver reaches Xmax to protect from catastrophic damage in the event of excessive dynamic peaks. In addition, the spiders have significant space between them to keep the coil centered in the tight magnetic gap. Every aspect of the suspension on the RSS265HE-22 has been designed to reliably deliver extreme excursion capability without adding significant distortion.

 

Aluminum cone and dustcap... a Reference series tradition

 

 

To visually fit in with the rest of the popular Reference Series Subwoofers, the RSS265HE-22 uses a rigid anodized aluminum cone and dustcap. The cone is significantly thicker to withstand the force that will be applied with such a powerful motor and to increase mass for a low Fs. Thanks to the rigidity and natural damping properties of aluminum, any cone breakup is pushed well outside of the pass band giving the RSS265HE-22 exceptionally flat response, even throughout the mid-bass and lower midrange frequencies. In addition, aluminum is an excellent conductor of heat, turning the entire cone and dustcap assembly into a large heatsink that effectively wicks heat away from the voice coil to further control power compression.

Incredible flexibility to add powerful bass to any system

 

The specs of the RSS265HE-22 have been balanced to operate in a variety of situations. Extended low frequency extension makes it ideal for subwoofer use in home audio and theater systems. With extremely small enclosure requirements, the RSS265HE-22 is also an excellent choice for use in high output car audio designs. Also, dual 2-ohm voice coils allow for stereo 2-ohm or mono 1-ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a more common 4-ohm load for greater amplifier compatibility. All of the Reference Series HE drivers are built to provide amazing low frequency response with unbelievable power, impact, and detail.
