The PMC8 SUB is a true low-frequency reference monitor which extends the bass response of your speaker system, imparting more of our signature ultra-clean, ultra-fast low end to any setup.

The PMC8 SUB can be used as a compact stand-alone subwoofer within conventional multichannel systems, or as an XBD cabinet, creating a full-range PMC6 XBD midfield monitor. When used in this way, the dedicated ‘XBD’ DSP mode marries the speakers and sub unit together, creating a coherent full-range system. Our subs are also perfectly suited to use in multi-channel and immersive systems, as our ATL™ bass-loading technology provides a gentler low-order LF roll-off than conventional ported cabinets, allowing a smoother, seamless integration between the height and surround channels and the sub.

Featuring one custom eight-inch long-throw bass-driver, the PMC8 SUB is powered by a single 300W Class-D amplifier and controlled by the same powerful DSP engine as our other active models. DSP facilities include sophisticated room boundary equalisation options, parametric EQ, time delay, phase inversion, and the unique XBD mode, all configured via the loudspeaker’s rear panel or the browser-based SoundAlign™ software.

Customer Reviews

"I have only heard a few pair of speakers translate emotion the way my PMC 6s do. The imaging is impeccable. A good mix feels perfectly 3 dimensional, like it's right in front of me. With the Sub 8 integrated, my system goes in to the 20Hz range and feels perfectly balanced. I'm in love."
Mr K, Lake Oswego
"Superb products. When I first installed my PMC6 I had a religious experience. Now the PMC8 SUB has rounded off my bass response - it's phenomenal how tight and imaged it is. For all these years I didn't know what was missing - proud to be part of the elite now. Just don't tell too many people! ;) All the best"
"As usual.. After buying from a friend the TwoTwo6, I added the Sub 8 to get even a cleaner image and jesus christ.... Even watching a simple youtube video makes me feel like the video is being presented right in front of me"
Mr E, Tel Aviv
"These speakers sound insanely good. I'm feeding them with AES digital from a Motu 8D from my mac. The resolution and accuracy on the all digital-to-the-speaker pipeline is incredible. Can't really listen to any 16 bit recordings now that I've heard 24bit 96khz digital on these guys. I'm a former professional user now hobbiest and this PMC6 XBD with PMC8 SUB setup is far beyond my expectations. I'm excited to use your on-wall cinema product for the buildout of my Atmos theatre when our new space is built in 18 months."
Mr R, Vancouver


If you are a professional who needs the last word in reliable reference monitoring in a compact form, then the PMC6 active two-way is the answer.
Adding a PMC8 SUB unit to the PMC6 easily upgrades the system to a twin-cabinet XBD monitor system. Find out more!

SOUNDALIGN digital interface
soundalign devices
The SoundAlign™ web interface is a simple and intuitive means of controlling and configuring our nearfield and midfield active monitors and subwoofers. Each monitor incorporates an internal web server accessible over a standard wired Ethernet connection using a web browser on any smartphone, tablet, PC, or Mac. It makes set-up easy, whether it’s stereo or the most complex immersive system.
One of the keys to our legendary natural, uncoloured sound is our Advanced Transmission Line (ATL) bass-loading. ATL uses energy generated by the bass unit in a much more intelligent and efficient way than speaker designs based on ported or sealed boxes. Our Laminair airflow technology further enhances ATL and improves definition, timing and eradicates unwanted air noise.

Conventional monitors have narrow dispersion which restricts the width of the accurate listening area
standard dispersion
PMC monitors have wide dispersion to provide accurate sound across the widest possible listening area
PMC wide dispersion


All PMC monitors have ultra-wide dispersion and a linear off-axis response. This creates a vast sweet spot for stereo and a seamless sound field for immersive formats, allowing sounds to be placed and adjusted with complete precision.
