RANSDUCERS
: The midrange drivers seamlessly comple-
ment the titanium-dome tweeter and offer nearly perfect pistonic motion, which eliminates the uncontrollable
flexing found in conventional cones. The inverted dome is driven precisely at its center, which cancels resonances
inherent in cone materials. The result is ruler-flat frequency response beyond the crossover point.

RANSDUCERS
: The low-frequency drivers deliver
precise, undistorted bass reproduction that matches the titanium tweeter and midrange. The powerful neodymium
magnet provides its own video shielding (S4VC and S4HC), allowing for flexible placement near video monitors.
Cast-aluminum frames remain rigid even at the highest volumes, avoiding the distortion found in some other speaker
designs. The aluminum doesn’t affect the magnetic field, so driver movement is precise.

OICING
: Synthesis Four uses common voicing across the front three channels. Since identical drivers
are used, each speaker has the same tonal qualities; thus, as a sound is panned from one side to the other, there will
be no change in timbre.

HIELDING
:
All front speakers are magnetically shielded, allowing you to place them near video
monitors without generating interference or distorting the picture. (S4Ai is not magnetically shielded.)
