This is a very high output precision loudspeaker that utilizes an 8” woofer and a 1” compression horn driver. Very high sensitivity is one of the hallmarks of this speaker. Numerous prototypes and designs were evaluated to insure that this speaker would not only be loud, but exceedingly musical! You can listen to these loudspeakers for hours at very high levels with no fatigue. An audiophile grade crossover is used in the design of this speaker.
