The cone of the Magnum Opus is individually hand made and hand tuned. it is composed of KVG Laboratories RRCF-2 Radially-Reinforced Cellulose Fiber, carefully hand-doped to eliminate cone cry then trimmed by a surgical-quality laser for exact balance and reduced non-musical distortion. With a cone this large, any imbalance can lead to disaster, or at least to horrendous distortion. The motor features a 4-layer, 3.9" voice coil operating in a precisely-focused magnetic field. aluminum heat sink fins prevent power compression and reduce operating temperatures, giving the Magnum Opus its high quality. A "double spider" rear cone suspension assembly keeps the voice coil centered exactly in the high precision magnetic field.
The Magnum Opus cannot be equalled. It is as close to a universal music instrument speaker as can be attained: any instrument, any style of music, any type of amplifier performs at a level of tone and quality so superlative as to defy written description. All other music instrument loudspeakers are pale, mere shadows of tone, breathy whispers of sound in comparison to the Magnum Opus. This limited edition loudspeaker will take both your music instrument and your musical expression to places beyond your dreams, beyond your previous experience, into realms that you have never before ventured. The Magnum Opus, quite simply, will change your electric music instrument from caterpillar to butterfly.
We decided to make something that is the essence of '70s sound: small paper cone woofer, piezo tweeter and a classic old-school (pre-Theile/Small parameters) bass-reflex cabinet. That Seventies Speaker One brings back the sound of 1970s-vintage stereo in a new-production loudspeaker.
Like many 1970s originals, That Seventies Speaker One has the same features that were "cutting edge" for the day:
As with most 1970s speaker designs, That Seventies Speaker One sounds best when placed in the room's corners and aimed toward the center of the room. Alternatively, That Seventies Speaker One may be mounted on a wall, placed on a stand and set against a wall or placed on bookshelves. Most modern audiophile speakers are intended to be placed on stands in the middle of the room, away from the walls. Although That Seventies Speaker One can be placed the same way, the bass may be deficient because That Seventies Speaker One uses the wall as an extension of its woofer, and therefore needs the close proximity of a wall or a room corner to achieve its deepest bass.
