PMC, a renowned British loudspeaker brand, launched its highly anticipated Prophecy Series last year, which immediately attracted extensive attention upon release. At the recently concluded 2025 Guangzhou International Audio & Record Show, New Han Jianye from Hong Kong exhibited and demonstrated the PMC Prophecy Series in their demo room. During the show, Mr. Luk Hing Wai, PMC’s Business Development Manager for Asia Pacific, North and South America, visited the venue and kindly accepted our interview.

Taking this opportunity, Mr. Luk introduced the brand-new Prophecy Series speakers in detail, and also shared PMC’s technical improvements and plans for future new products. It is reported that the Prophecy Series made its domestic debut at the Beijing Show last June. Notably, the series had already been on sale in the Guangzhou market for some time before that, and this 2025 Guangzhou show marked its first public appearance in Guangzhou.

Revealing the Three Core Design Goals of the Prophecy Series
According to Mr. Luk, the Prophecy Series was led by Oliver Thomas, current CEO and son of PMC founder Peter Thomas.In December 2024, before the official launch of the Prophecy Series, PMC invited distributors from around the world to its factory for an exclusive preview and listening experience. At the event, Oliver Thomas elaborated on the three core objectives set for the Prophecy Series from the very beginning of its design:

1. Outstanding Bass Performance – PMC speakers feature the exclusive ATL (Advanced Transmission Line) technology, with an opening at the end of the transmission line known as the Laminair vent. Oliver Thomas believed there was still significant room for improvement in this design. Through computer simulation, increasing the number of Laminair vents from 6 to 9 was found to significantly enhance ATL performance and deliver more layered bass. Based on this, PMC developed the newly designed LaminairX aerodynamic transmission line outlet, which is applied to the Prophecy Series.

2. Wider Midrange and Treble Dispersion – To achieve this, PMC carefully designed waveguides at the speaker driver openings. As Mr. Luk explained, conventional waveguide designs often produce harsh, unnatural sound, especially on tweeters. PMC engineers conducted extensive simulations and finally created waveguides that enable natural soundfield dispersion. In particular, the Prophecy 7 and Prophecy 9, equipped with a midrange driver, feature a quatrefoil-shaped midrange waveguide inspired by the waveguide of PMC’s early flagship BB5 speaker. This design, called PMC’s proprietary N‑Compass Soundfield Diffuser, spreads sound evenly across the listening area, greatly expanding the sweet spot and ensuring “nearly the same soundstage no matter where you sit”.

3. Suitability for Small-Space Placement – To this end, the Prophecy Series features a narrow baffle and slim cabinet. This compact form does not compromise performance; instead, it delivers impressive low-frequency response, wide soundstage, and a broad listening sweet spot in both small and large rooms.

Feedback from Listeners
Mr. Luk shared several examples of listener feedback:

In June 2025, PMC launched the Prophecy Series simultaneously at the Florida Audio Expo in the U.S. and in the UK. Many visitors commented: “I’ve never heard bass like this!” When asked to compare it with American speakers, they noted that PMC’s bass is layered and articulate, whereas many American speakers focus on impactful, forward bass. The Prophecy Series provides ample bass while clearly distinguishing different bass instruments, without masking midrange and treble details.

Mr. Luk also shared a personal experience. His wife, not an audiophile but with sensitive ears, had listened to a well-known British speaker pair at home for nearly 10 years, often enjoying Hotel California off the sweet spot. After listening to the Prophecy Series, she said: “I’ve listened to this song for 10 years with the old speakers, but with these, I hear details I’ve never noticed before.” She also said she felt no listening fatigue even after 10 minutes, and suggested selling the old speakers and keeping the PMC Prophecy model.

At the 2025 Guangzhou show, many listeners were amazed that such a slim cabinet could produce powerful low frequencies, even suspecting an external subwoofer was used. This is a hallmark of transmission line speakers. Mr. Luk emphasized that the attractive LaminairX outlets are not just for aesthetics: they are precision-engineered aerodynamic outputs, integrated with the aluminum alloy base to further reduce harmonic distortion.

He added that the Prophecy Series is extremely easy to place. While typical speakers struggle in small, irregular rooms of 10–20 square meters, the Prophecy Series adapts very well to such spaces.

Q & A with Mr. Luk on the Prophecy Series

After Mr. Luk’s detailed introduction, he answered several key questions from our journalist:

Q: What is the market positioning of this series?

Mr. Luk: The Prophecy Series is positioned as a mid-range product line and will gradually replace the 25 Series. The 25 Series is still available, now mainly as an active version. Notably, the amplifiers for the active models are designed and built in-house by PMC, not sourced externally.

Q: PMC’s transmission line technology has evolved over generations, with the Laminair vent now in its second generation. Will further improvement hit a technical bottleneck?

Mr. Luk: I can share a little now. We have engineering drawings showing 6‑port and 9‑port Laminair designs. Going from 6 to 9 ports made a dramatic difference, speeding up airflow. However, we cannot add ports infinitely—20 ports, for example, would yield diminishing returns, increase the vent area, and drastically raise costs. For the Prophecy Series, 9 ports is the optimal solution. I can share more details next year or the year after.

Q: The Prophecy Series includes a center channel speaker. Does that mean it supports both stereo and home theater multi-channel use?

Mr. Luk: Exactly. The center channel is crucial for movies. The Prophecy center uses the N‑Compass waveguide from our CI custom install series, making it an excellent home theater solution. For a typical 5‑channel setup, we recommend Prophecy 7 or 9 as front speakers, paired with the Prophecy C center and a pair of Prophecy 1 surround speakers for the best performance.

Q: Will there be a dedicated subwoofer for the Prophecy Series in home theater systems?

Mr. Luk: There is no dedicated subwoofer in the Prophecy Series itself. However, I can reveal that we plan to launch a subwoofer in the CI Series that will pair perfectly with Prophecy. Our 25 Series also has a subwoofer, but it may be pricey and relatively small when matched with Prophecy. In our professional line, the PMC 8 active subwoofer, originally designed for recording studios, also works beautifully in home theaters.

Q: Since PMC transmission line speakers have such strong bass, can we skip a subwoofer in home theater?

Mr. Luk: It depends on your needs. We have a real-world example: a theater with a 7.0.4 configuration (no separate subwoofer), using our MB2 XBD speakers — the MB2 with an integrated XBD subwoofer designed specifically for it.

Finally, Mr. Luk revealed that sales of the Prophecy Series have been very strong since launch. It offers affordable pricing and significantly improved craftsmanship compared to previous models. The U.S. is the top market, followed by China. Since China only officially launched in June last year, sales are expected to grow further. Australia has also performed well, and surprisingly, sales in Taiwan, China have been exceptionally strong.

Regarding future new products, besides the upcoming CI Series subwoofer, Mr. Luk mentioned that PMC’s flagship Fenestria may also receive an update and upgrade.
