RUBBER SURROUNDS
This material provides optimal
cone-edge suspension and absorbs
distortions that may travel up the
cone edge. The benefit is an audible
reduction in distortion.
PROGRESSIVE SPIDER
Each Reference subwoofer features
aprogressive spider, applying
progressively more force as the
cone travel approaches its limit.
The result is a subwoofer in better
control when pushed to extreme
excursions, delivering more bass,
free from distortion and breakup.
PROPRIETARY TINSEL-
LEAD SUPPORT
This prevents tinsel-lead slap
and ensures that the leads stay
attached to the cone, even at
the woofer’s excursion limits.
PROPRIETARY FRAME
The unique frame design used on
all Reference subwoofers provides
adecrease in mounting depth, while
maximizing woofer excursion. If you
want to add subwoofers in a pickup
or in a confined space, these
subs are the ideal solution.
