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.

Click here to download SC-III brochure hfe_dunlavy_audio_labs_sc-iii_flyer_en.pdf
The Dunlavy Audio Labs SC-III has often been described as the "perfect loudspeaker." With a footprint of only 15.25" wide and 15.25" deep, an elegant enclosure, and a suggested retail price starting at only $3,995.00 per pair, this three way design is pure pleasure - aesthetically, sonically, and fiscally.
Capable of amazing dynamic performance, the SC-III also has an astonishing ability to disappear into a room, leaving only music. This is accomplished by it’s unique, time aligned symmetrical driver array and phase coherent first order crossover, which minimizes floor and ceiling reflections allowing the listener to reach a level of musical purity that is unequaled by the competition.
With it’s 1" dome tweeter, two 5" cone mid-range drivers, and two 6.5" heavy duty woofers, the SC-III is capable of recreating the most delicate musical transients with clarity and precision, while also possessing the capability of rocking out with power and speed. The SC-III is truly a "renaissance" loudspeaker that meets the needs of the budget conscious music lover who has a wide range of musical tastes.
With it’s incredible versatility, exquisite lines, and amazing value the SC-III just might be the consummate loudspeaker for "everyman."
"They (SC-III’s) are exactly that type of rare product that both confirms ones aspirations and pushes one to new levels of understanding. Emotionally, these are the most direct and natural speakers I’ve ever heard."
- Todd Warnke; Soundstage!
