The Majestic Diamond IIô, represents the state of the art in Audio Monitors. Although many manufacturers before us have made this statement the true definition of this accomplishment requires more than a special listening panel in a special room. The Majestic Diamond IIôsolves many other problems that must be addressed before sound reproduction can benefit the consumer on such a thorough scale in todayís modern lifestyle. Audio is actually more involving than a high definition picture just ask any serious audiophile and now it is possible to have the best of both worlds. The sound stage should tell you what is going on even if a picture is not present. A musical event is wonderful when we close our eyes and imagine the performers in front of us and feel the ambiance of the hall. Some feel that this would be better than watching it because you can be there with your eyes closed.

The Majestic Diamond IIô is just such a product that rewards you with the pleasure of sound well integrated with your lifestyle. Sure you would like a dedicated sound room but it would be nice to share the experience with others or listen from a variety of positions. This is a must when you combine video with your audio source and people are everywhere standing, seated even on the floor watching the HDTV. This describes a typical family setting or social gathering with people perhaps conversing while enjoying the music or movie.

The Majestic Diamond IIô multi-way audio monitor uses the Embedded Transmission Line (ETLô) technology, which controls any internal resonance. You will know that this handsomely constructed monitor means serious business the moment that you remove it from packaging. You will notice the quality 5-way gold-plated binding posts, which allow many ways to connect the speaker to audio cables.

Low Frequency Section

The foundation of the Majestic Diamond II features a 5.25î woofer midrange with a stiff coated paper diaphragm. The vented driver is acoustically corrected by its dual portedETLô enclosure internally to provide flat response and uniform dispersion characteristics. The resulting pistonic motion of the woofer driver diaphragm extends from its lower ranges right through its 4.5kHz crossover point and beyond. Normally dispersion problems confuse any multi-way speaker regardless of design methodology resulting in restricted dynamic power response and confusion in the acoustic presentation. The ETLô prevents the disturbing axial breakup modes from occurring while maintaining constant acoustic impedance with frequency around and through the crossover region. The linear dispersion characteristics allow a simple first order electrical crossover to bring about a total 12db/oct low pass slope for the woofer. The result is a desired neutral minimum low pass phase characteristic even off axis. Low frequency roll off is gradual, not abrupt as with typical ported systems therefore allowing you to use the roomís characteristics to extend the bass to subwoofer depths in some cases.

High Frequency Section

Accomplishing stellar woofer performance demands a neutral high frequency section to extend the coherent low frequency foundation into the highest frequency ranges. The conical based 2-inch PPM tweeter incorporates an aluminum phase plug to enhance higher frequency dispersion while a 200 Hz low frequency shelf assures that the driverís main resonance does not influence its output. The relatively high 4.5kHz crossover point maintains a minimum cone travel, which is desired for this driver. This tweeter when used in the ETLô internal acoustic environment becomes neutral and matched to its companion woofer. How is it possible to accomplish such a goal when typically woofers are just plain different from tweeters in all respects? ETLô technology accomplishes this by normalizing the internal operating environment of each driver.

The industry has been searching for harder materials to minimize the breakup in tweeters even by using synthetic diamonds. The best sound comes from natural materials such as paper or a closely engineered comparables such as the PPM cone employed in theMajestic Diamond IIô. Our ETLô technology precludes the need to use rigid and artificial materials by supporting the tweeter with real time backpressure that prevents axial mode breakup from occurring. The voice coil now has help to assure that the tweeter remains a piston throughout its frequency range.

Crossover Network & Environment

The crossover point comes into question again when describing the tweeterís contribution. It is important that the woofer and tweeter maintain similar dispersion characteristics at and around the crossover frequency. It would also be good to be able to maintain the important similar characteristics right through the audible range. TheETLô maintains that similarity even though the drivers are of a different frequency range and construction. Why do we choose a 4.5 kHz crossover point? The woofer must crossover when its dispersion coverage is similar to the tweeter. This assures that there is a seamless transition at and about the crossover point with the woofer-tweeter radiating characteristic essentially identical in this range. This also allows us to use a simple 6db/oct high pass slope for the woofer, which minimizes electrical phase shift. TheMajestic Diamond IIô sounds as if it is a single driver speaker even at very close distances while improved coherency establishes a slower sound decay with distance than with existing loudspeakers. This is because the internal pressure returned to each driver maintains the consistent velocity differential with the ambient at all frequencies. The drivers have similar cone shapes affording similar dispersion characteristics in the crossover range. The elimination of breakup modes in the woofer allow for precise crossover design and operation when blending with the tweeter even when high dynamics are present.

The physical path difference between drivers normally associated with multi-way designs will not be heard since the true priorities are unmasked. The seamless acoustic presentation is neutral to responses from reflections to maintain coherence in any environment.

Superior Dynamic Range

An inherent benefit of ETLô technology is that of maintaining its corrective pressure for the cone at high sound pressure level (SPL). This correction reduces dynamic current in the coil allowing for natural peaks at high average volumes and greater dynamic power handling. Linear cone excursion is maintained out to and slightly beyond the normal excursion limit. No compression here and with the large radiating surface of the cone tweeter excursion is kept to a minimum even in these ideal conditions.

The woofer also maintains superior dynamic capabilities with its enclosure dedicated to maximizing its linear excursion capabilities. Operating as a piston over its frequency range insures that a linear velocity is present right through the crossover point with compression far from the driverís output even at high dynamic levels.


Long term listening is possible with the Majestic Diamond IIô audio monitor even at high levels without fatigue. The Majestic Diamond IIô is also the ideal closely positioned studio monitor capable of discerning even the finest detail without excessive level. This important characteristic allows use in smaller listening rooms with audiophile quality especially when positioned properly.

Off axis listening maintains the soundstage almost as if you were still centered and you can stand, sit or be at floor level and still experience precise sound quality with a good soundstage. This is not an accomplishment to be taken lightly when choosing a speaker for your lifestyle. You will even find yourself moving around without missing a single enjoyable beat of your favorites.

Today we assume that enjoyable sound is only possible with perfect analog or digital sources while many less quality sources provide us with the music we love. The Majestic Diamond IIô will have you looking for and listening to all of your favorites regardless of the recording era quality or the medium. Sources such as mp3s, FM, tape, and phono will surprise you with their musicality and audible detail.

The Majestic Diamond IIôís neutral low frequency roll-off makes it a perfect match for the Magellan subwoofer series. Other sub designs will benefit from the coherent low frequency output of the Majestic Diamond II however you will only get close withoutETLô technology in the subwoofer design. While both the Magellan VI su and theMagellan VIII su work exceptionally well with the Majestic Diamond IIô the latter is especially synergistic with this monitor. A single or pair of the Magellan VIII su mated with a pair of Majestic Diamond IIô audio monitors represents the finest audio speaker system available today regardless of price and its amazing properties can be enjoyed in almost any listening room without room treatment when using quality components. Of course if you are just upgrading your speakers from your old mid-fi system, you are in for a wonderful surprise when you hear how good your original components really sound.
