PAM™ design manifests in loudspeakers as waveguides with one or more 
selective impedance discontinuities. The impedance discontinuities may be a 
consequence of changes in cross section, or a consequence of junctions in the 
waveguide. 
 
PAM™ can be used to make the response of a loudspeaker flat and at the same 
time minimise cone excursion by inserting multiple cone minima in the pass 
band.  Accordingly PAM can be used as the basis of high fidelity, low distortion 
loudspeakers and subwoofers. For the Whise 1500 HD-A

® 

subwoofer, the result 

is very loud bass with incredibly high efficiency, and an almost ideal frequency 
response over its chosen frequency range. This technique has been employed in 
all Whise high-end, professional and cinema subwoofer designs, and is praised 
globally by audio professionals, including Tomlinson Holman of Lucasfilms THX 
fame. 
 

VR/UR™ (Velocity Reflex/Ultra Reflex) 

VR/UR™ is a subwoofer technology originally developed for automotive 
applications. VR/UR™ is an acoustically filtered infinite baffle system that has the 
capability of providing quite high sound pressure levels (‘SPL’) at low frequencies 
with a small enclosure size. It also has the unique advantage of providing high 
SPL without causing exterior nuisance. The Whise 1500 HD-A

® 

subwoofer is 

evidence of the power of this technology.
