PMC prophecy7 Floorstanding Speakers, Pair

PMC prophecy7 floorstanding Speakers Key Features:

• ATL Bass-Loading - Natural, realistic sound and deeper bass from a smaller cabinet
• Laminair Ports - Faster, cleaner bass with less air noise due to reduced turbulent airflow

Product Description: 

Integrating one of PMC’s legendary soft-dome midrange drivers with prophecy’s finely-honed treble and bass engineering, prophecy7 enhances the listening experience to unprecedented heights for both music and movie enthusiasts.

The prophecy7 sets new benchmarks in its class, challenging the notion that only larger speakers can deliver exceptional performance. Featuring a dedicated mid-range driver mounted in a unique waveguide—exclusive to the Prophecy series—this innovative three-way design ensures stunning vocal clarity and thrilling instrumental textures, all presented with remarkable transparency.

By allowing the bass unit and tweeter to focus on their respective frequency ranges, the prophecy7 optimizes sound quality, with each driver working in harmony thanks to a meticulously hand-built crossover. This precision-engineered crossover ensures perfect driver integration, elevating the overall listening experience. The custom bass driver, paired with PMC’s latest Advanced Transmission Line and enhanced by LaminairX airflow technology, delivers powerful, deep bass while maintaining exceptional refinement. Despite its compact size, the prophecy7 proves that a three-way design can be both incredibly detailed and impressively dynamic.

ATL - Advanced Transmission Line

The hallmark of PMC’s renowned, natural sound lies in its Advanced Transmission Line (ATL) bass-loading technology, a system that has been professionally tested and trusted globally. For a deeper understanding of how it works, explore more from the tech lab at PMC.

A transmission line speaker design positions the drive unit at the end of a long, highly-damped tunnel that absorbs unwanted mid and high-frequency energy emitted from the rear of the driver. Meanwhile, it allows the lowest frequencies to exit the line in perfect phase with the front-facing radiation, significantly boosting bass performance. This technology is effective across a wide bandwidth of approximately two octaves, centered around the transmission line's resonant frequency. Within this range, it tightly controls the movement of the drive unit, dramatically reducing distortion and enabling higher output levels.

The resonant frequency of a transmission line is determined by the acoustic length of the line, which corresponds to one-quarter of a wavelength. Achieving this balance requires careful consideration of numerous factors, from the driver’s parameters to the length, taper, profile, and foam placement within the line. Each of these variables affects the others in intricate ways, meaning they must all be optimized together for the best result.

The complexity and precision needed to perfect this design make it a challenge that only a few companies, like PMC, have mastered—explaining why PMC is one of the few to successfully develop and refine transmission line speakers.

Lanimair X Technology

A decade after PMC’s engineers revolutionized audio with the introduction of Laminair, the Prophecy series showcases the latest advancement: LaminairX. This new iteration works in perfect harmony with PMC's ATL technology, raising the bar for both sound quality and musical enjoyment.

LaminairX unlocks the full potential of ATL, offering improvements that are both technically groundbreaking and immediately noticeable to the listener. ATL designs rely on high-speed airflow and complex fluid dynamics, but LaminairX takes things to the next level. By introducing precise aerodynamic control, LaminairX reduces turbulence and drag, minimizing resistance and cutting harmonic distortion by up to 3dB. This results in cleaner, tighter bass with exceptional timing and a dynamic range that’s simply unmatched.

Moreover, the all-metal LaminairX device is isolated from the main speaker enclosure using a layer of sustainable, pure cork. This design feature not only stabilizes the speaker but also anchors it for superior control, enhancing overall performance.
