[Duntech Marquis]

Duntech Marquis

The Marquis also has a time aligned, five driver arrangement.           The bass and mid-range drivers have diecast magnesium chassis. The bass drivers use a vented magnet system and feature a special, coated, pulp paper cone.           The mid-range drivers are double magnet design and have rubber suspension for low resonance.           The double chamber tweeter is dome type, with a fabric diaphragm and ferrofluid for efficient cooling and damping.           The cabinet is designed to provide optimum rigidity and its size has been matched to the performance requirements of the drivers. All drivers have separate sealed enclosures.           Acoustic felt is matched to the requirements of the loudspeaker and tailored to the geometry of the enclosure.           The loudspeaker grill is covered with acoustically transparent cloth and the cabinet is hand finished in high quality wood veneers.

[Duntech Ambassador XL]

Duntech Ambassador XL                                 
     

The Duntech Ambassador XL combines elegant layout with the astonishing life-like sound for which Duntech loudspeakers are world                                   renowned. Created entirely at our Australian facility, it brings to the respected Classic Series a mid-priced loudspeaker with all of the quality, precision and performance characteristics synonymous with the Duntech name. The Ambassador XL produces an extended, superbly balanced response with a bass emphasis which is suited to both Audio Visual and pure music applications. Hand crafted from the finest Australian or Imported timbers, the stylish design will complement many decors. The Ambassador XL is the Ambassador to the Classic Series and is truly deserving of the title Classic.

               
     

A three way four driver design, the Ambassador XL is a remarkable loudspeaker. The drivers are of a high quality fibre construction utilising high temperature aluminium voice coils and magnesium chassis. The tweeter is a fabric dome made from a proprietary material called Sonotex. Its voice coil is wound with pure silver wire. Treated with acoustic absorbent felt, the tweeter is time collimated.                   The Ambassador XL incorporates a proprietary 210mm (8") woofer mounted in the side of the cabinet. This driver provides the flexibility and bass performance which is often called for in A/V applications. Providing extension below 30Hz in typical rooms, the Ambassador XL is the ideal entry level loudspeaker for the more serious audio and A/V enthusiast. The crossover is a first order type which provides smooth and flat phase and amplitude response. Equipped with gold plated precision terminals and wired throughout with heavy gauge low loss silver plated cable, it is suited for bi-wiring or passive bi-amplification.

[DAL WL-1]

DAL WL-1

The WL-1 is an attractive, almost full-range "Wall-Loudspeaker" with true audiophile performance and specifications.

Its relatively small size, minimal depth, low weight and broad horizontal directivity make it a perfect choice for wall-mounting within rooms whose size and/or layout will not accomodate typical full-range audiophile loudspeakers.

Despite its size, minimal depth and appearance, the WL-1 provides almost full-range, true "audiophile-quality" reproduction of even the most complex musical sounds and transients. Suplemented with a high-quality sub-woofer, the WL-1 is capable of competing with much larger loudspeakers with respect to overall accuracy.

Indeed, the WL-1 will require many audiophiles to re-evaluate their opinions concerning the ability of wall-loudspeakers to achieve truly accurate reproduction, rivaling that of much larger and more expensive loudspeakers.

It is a loudspeaker that deserves to be seen and heard - if space within your listening room does not permit the use of conventional, physically much larger loudspeakers.

[DAL SC-VI]

DAL 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."
- Steven Stone; Stereophile

      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."
