G-PALâ„¢ Gold-Anodized Pure-Aluminum Domes.
Exceptionally rigid low-mass domes with treated textile suspensions
ensure remarkably uniform and instantaneous power response. The elevated
position of the dome provides better ‘air’ and frequency response that
is smooth, pure and clear.
S-PAL Satin-Anodized Pure-Aluminum Midrange and Bass / Midrange Cones.
Very high stiffness-to-mass ratio and outstanding internal damping. The
result? Remarkable midrange clarity, superb extended bass response and
freedom from unwanted resonances and distortions.
IMS/SHOCK-MOUNT Isolation Mounting System. This
unique butyl-rubber driver fastening system found on all Studio Series
drivers is a progressive system of critically placed isolation inserts
and gaskets that decouple drivers from the speaker enclosure itself.
This leading-edge ‘baffle-less’ technology reduces driver / enclosure
interactions to inaudible levels.
High-Velocity Low-Noise Aluminum Ports. Bass efficiency and minimum turbulence distortion for cleaner and more articulate bass response.
