Cinergy Sub15

The exceptional Cinergy Sub15 can be installed in the wall, stacked or used as a floorstanding unit.

Better yet, you can combine it with other Cinergy Sub15 and Cinergy 300 units to create a hidden ‘sound wall’, delivering the kind of audio rarely experienced in the home. In order to achieve the full THX-certified experience, Cinergy Sub15 needs be to paired with Monitor Audio’s IA750-2 / IA750-4 installation amplifier. As such, the Cinergy Sub15 is only sold along with the IA750-2 / IA750-4, ensuring you enjoy great sound without compromise.

True cinema sound at home

The dream of experiencing true cinema sound in your own home is now a reality thanks to Monitor Audio’s incredible Cinergy system. Cinergy offers all the thrills of the very best cinema, but focuses the experience around you and those closest to you. With Cinergy you create a completely bespoke cinematic experience; immersive, precise, natural, and private.

Transparent Design Philosophy

Monitor Audio believe the ultimate loudspeaker is one capable of producing sound as laid down by the artist so accurately that it becomes transparent. The physical design should be sympathetic to any environment and work in harmony with the desire for transparency. Cinergy was created as a result of this Transparent Design Philosophy, and is engineered to ‘disappear’ into your home cinema, allowing you to experience the visceral thrill of the very pinnacle of movie sound, without distraction.

THX® Certified Ultra

THX is the gold standard for audio and visual fidelity: a globally recognised mark assuring Cinergy delivers the ultimate home cinema experience. It’s not simply a set of measurements done on a computer or in a lab; THX certification is only achieved using the dynamics of real-world listening, so you can have the utmost confidence that Cinergy will deliver a breathtakingly realistic home cinema experience.

Your cinema, your way

The best home cinemas are purpose-built from the ground up, enabling you to create a completely bespoke experience all of your own. Cinergy gives your installer the creative flexibility to design and build a cinema that exactly meets your requirements. Modular designs, bespoke isolation options, clever fixing methods and a range of versatile, high-performance loudspeakers combine to provide an experience that’s perfectly attuned to your chosen space.


For the most discreet high-performance system imaginable you can locate Cinergy completely within the walls of your home cinema installation. It’s even possible to crate a ‘sound wall’ behind your screen for the last-word in concentrated power.


If a completely installed cinema isn’t an option, you’ll be pleased to hear Cinergy performs equally as well positioned on-wall. That’s why they have made sure the Cinergy speakers look as good as they sound, and offer grilles if required.


The Cinergy 300 is not only the largest speaker in the range, it’s also the most versatile in that it can be used as a freestanding model. This enhances system building flexibility, allowing you to partner it with other models in the range used on-wall or in-wall.


Your home is like no one else’s. Fortunately, Cinergy is designed to adapt to every possible scenario. For example, the mid-tweeter array on the Cinergy 100, 200 and 300 easily rotate, depending on whether you’d prefer it to be a vertical or horizontal install. So there’s no need to compromise on your design vision when you’re searching for the perfect sound.

Small details

Because small details make a big difference, Monitor Audio engineers have developed a range of practical isolation accessories for Cinergy. L-shaped bracket isolators and 3-layer silicone feet isolators reduce vibrations by up to 18dB, and ensure optimal performance. These small differences, have a big impact on your enjoyment.
