SC-VI / Model Information
Last post by Tranquility Bass - October 20, 2023, 09:45:50 PMDAL SC-VI
In a world where advertising hyperbole regularly makes unsubstantiated claims for loudspeaker accuracy, the SC-VI offers incontestable proof of what today’s best technology has to offer. Indeed, the SC-VI presently has no equal or peer in the marketplace regardless of price. It is a benchmark product by which all other speakers will be judged.
The SC-VI incorporates several important and meaningful advances in technology, features, and performance that cannot be found in any other loudspeaker, save the other Dunlavy Audio Labs models. For example, the impulse, step, and squarewave responses of the SC-VI (critical performance parameters that correlate with perceived musical realism) are equal to or better than those associated with the most expensive, top of the line CD players and D/A processors. It’s high efficiency, coupled with a very flat and largely resistive input impedance, means that the SC-VI can be easily driven with most high quality power amplifiers possessing a power rating of only 100 watts per channel or more.
With four 15" woofer drivers, four 8" bass drivers, four 5" mid-range drivers, and two 1" dome tweeters, the SC-VI speaker system is capable of reproducing every recorded note with stunning realism and accuracy. Bass frequencies are thunderous and fast, unmatched in visceral impact. With the SC-VI, you not only hear the bass, you feel it. The mids and highs are clean, quick, and effortless, and are perfectly integrated with the bottom end. Within a good listening environment, a pair of SC-VI’s can re-create recorded music with a level of precision that can only be described as an exceedingly close encounter with the original live performance - limited only by the accuracy of the recording, the acoustics of the listening environment, and the quality of the other components in the playback system.
Stereophile magazine awarded the Dunlavy Audio Labs SC-VI it’s "Loudspeaker of the Year" for 1996.
"One of the finest sounding loudspeakers that I have ever heard were the Dunlavy Signature Collection SC-VI’s...These are extraordinary transducers that are absolutely effortless and totally authentic in their ability to recreate the illusion of reality with distortion-free dynamic range that mimics live music and film effects. Two matched pair of SC-VI’s in a home theater entertainment system would be addictively one of the ultimate home theater experiences you could package."
- Gary Reber; Widescreen Review
"So does the SC-VI get an A-rating? Are you kidding? It gets an A+ with at least five gold stars, a bullet, and a trio of dollar signs to designate them a stone cold bargain. Anyone, no matter how tweaky, who purchases any other more expensive large loudspeaker system without at least hearing a pair of properly set-up Dunlavy Signature SC-VI’s is an utter fool. I’m no fool - I bought the review pair."

SC-V / Model Information
Last post by Tranquility Bass - October 20, 2023, 09:39:43 PM DAL SC-V
With performance exceeded only by DAL’s flagship SC-VI loudspeaker, the SC-V is truly without peer in the marketplace. Like the SC-VI, the SC-V stands alone in it’s ability to accurately reproduce even the most difficult, complex, and demanding musical passages.
The design of the SC-V was accomplished by competent engineering personnel while measuring virtually every relevant performance parameter that relates to the reproduction of sound. This results in a four way system capable of outperforming other speakers that cost five or six times the price. Starting at only $14,995.00 per pair (US suggested retail), the SC-V truly represents a price to performance ratio that is unmatched in the industry.
The unsurpassed performance of the SC-V is traceable to the meticulous attention given to the design goals such as extremely flat amplitude and phase response, incredibly low distortion, true phase coherency, simulated point source radiation, inaudible cabinet diffraction, symmetrical radiation patterns, broad vertical/horizontal dispersion, and precise pair matching. The optimally damped and sealed enclosure of the SC-V yields very natural and life-like reproduction of the full audible frequency spectrum.
If owning an SC-VI is like owning the "perfect car", owning the SC-V is like owning the same car with only five less horsepower and having to pay just half the price.
"John Dunlavy has done it again...the sound from the 300 lb. SC-V’s was, in my opinion, the overall Best at a Show that had no shortage of great sounding speakers."
- Robert Deutsch; Stereophile
"My nomination for "Best Sound at the Show" is the Dunlavy SC-V’s. The system was world-class: effortless, large, airy, focused, palpable, timbrally a pleasure, and exhibiting that certain je ne sais quoi."
- Jonathan Scull; Stereophile
"The SC-V's provided as much - and musically right - detail as I have heard from any speakers. I was so impressed that I have bought them to use as additional reference speakers."

SC-IV.A / Model Information
Last post by Tranquility Bass - October 20, 2023, 09:11:29 PMDAL SC-IV/A
As the newest addition to the Dunlavy Audio Labs collection, the SC-IV/A utilizes the most advanced technologies which results in a loudspeaker of remarkable performance and value.
Capable of full range performance in a three way design, the SC-IV/A offers extreme linearity, fabulous imaging, as well as stunning bass response (-3 dB @ 21 Hz). The impact and accuracy of the bottom end gives incredible realism to pipe organs, concert drums, and other low frequency instruments that other comparably priced speakers simply cannot re-create without a bloom or bloat. With the SC-IV/A, these bottom notes come fast and intense, and because of the extraordinary system impulse response of the SC-IV/A, they also disappear as quickly as they appeared. (An audio/video system featuring the SC-IV/A’s would offer unfathomable performance.) Incredible driver integration and total phase coherency via the intricately designed first order crossover and the time aligned, symmetrical driver array translates into an immensely deep sounstage, pinpoint placement of instruments, and rock solid vocals. The SC-IV/A offers true world class performance at a fraction of the price.
Like all Dunlavy Audio Labs Signature Collection loudspeakers, the SC-IV/A has been designed in our state of the art equipped facilities including two large anechoic chambers where each speaker is measured for frequency, impulse, step, waterfall, and impedance.
If the Dunlavy Audio Labs SC-V is the best high end loudspeaker value above $10,000.00, then the SC-IV/A is the best loudspeaker value under $10,000.00.
