The SC-II is a two-way loudspeaker aficionado’s dream come true. While most two-way loudspeakers either sit, precariously mounted, on required stands, or are housed in a diminutive floor standing cabinets, the Dunlavy Audio Labs SC-II’s enclosure stands a full 65" high. This allows for proper positioning of the 1" composite textile tweeter and the two 6.5" woofers so that the listener is immersed in music that is time and phase coherent.

The cabinet size of the SC-II (65" high x 8" wide x 10" deep, with an incredibly small floor space requirement of only one square foot) allows for substantial dynamic range without the use of ports or vents, which while allowing a cabinet of lesser size to achieve greater bass response, can also color the signal with the port or vents tuned frequency. The use of such devices can give the perception of "one note bass" and a high degree of repetitiveness with regards to the listeners perception of the music. Not so with the SC-II. Bass guitars, cellos, and drums are re-created with stunning realism, as well as truly amazing reproduction of vocals.

With it’s high efficiency, coupled with a very flat impedance curve, the SC-II is capable of being driven effectively with just about any type of high quality power amplifier currently available. In fact, with the SC-II’s amazing accuracy and even more remarkable price (starting at a suggested US retail of $2,495.00 per pair), a smart, value minded audiophile is capable of putting together a system capable of true world class performance at a very reasonable price.

Sure, there are two-way speaker systems costing many thousands of dollars more, but none are capable of reaching the level of objective performance achieved with the SC-II.

"I can state right here and now that the SC-IIs are outstanding performers, not only for two-way models, but also compared to just about anything else, including many top-grade three and four-way designs. In terms of full-range performance, the Dunlavy Audio Labs SC-IIs are among the finest speakers I have had a chance to audition in my own listening room. Indeed, the SC-II may be the best two-way speaker system available today, and if it is not, it certainly can give whatever is in first place a serious run for the money."
