About The SD4 Speaker Technology

The SD Speaker employs (4 smaller 6.5") very fast transient response aluminum-woofer drivers that are very powerful and stable. Working in unison these drivers produce a clean powerful dynamic sound. When designing the SD the goal was to have the single most import feature at the forefront, good transient response ("dynamic contrast"). A transient is a sound of short duration, and good transient response can only be achieved if the speaker can deliver its output quickly and cleanly without smearing the original sound, and be completely soundless immediately after. Transients contain the essentials of sound reproduction they provide the sharp pop from a snare drum, the cutting edge of digital sound, the dynamics of the human voice. Larger 2-way cabinet loudspeaker systems offer a relatively slow transient response, and the small high-frequency horn tends to beam a narrow, blaring sound at the listener—end result, muddy sound. By replacing larger speakers with four 6 or 8" drivers we increased the driver surface area while creating more punch and a tight, more focused low-end.
