Comes with S12 Sub Woofer

Ocean Way Audio has released an accurate, wide dynamic range reference monitor for the recording studio environment. The HR4 Reference Monitor is a 24”, integrated 2-way dual-horn system that can be placed in any environment to provide an exceptionally accurate monitoring experience.

At the heart of the acoustic design is HR4’s dual/hybrid waveguide system delivering a 100×40 degree window. Its unique design is realized with the aid of high-grade, 3D solid modelling. This accurate process allows for creating geometrically-complex surfaces that create accurately-matched and detailed imaging within the system. As a result, the HR4 delivers a stunning 100 degree dispersion pattern over a very wide audio range. An unusually-wide horizontal sweet-spot is revealed with rich detail across a broad area of the listening environment. The consistency of its stereo image, even at the far corners of the room, is delivered due to the highly consistent directivity response of the speaker system.

The HF driver is a high definition design with excellent mechanical linearity. The LF driver is geometrically reinforced aluminum cone with a vented cast aluminum chassis yielding optimum strength and low compression. Combined with the ported cabinet, the system is tuned to perfection with a seamless transition between the drivers. Our two-way, self-powered design delivers an unprecedented level of performance allowing for flexibility of placement in the room with a matched uniform frequency response of 35 Hz to 25 kHz, and an extraordinary 116 dB maximum SPL between channels. In spite of the HR4’s minimal footprint, its exceptional low frequency response eliminates the need for a subwoofer. However… for those who wish to play their music exceptionally loud, we offer a 3-Way model comprised of two additional cabinets, each with 12″ LF drivers.

We carefully select and match each set of components getting them as close as possible to achieve our high performance standards. Our process could easily be compared to building a fine musical instrument.

Designed by five-time Grammy® award-winning engineer/producer and iconic studio owner/designer Allen Sides, the S12A MkII’s design allows it to be equally at home supplementing bass frequencies for musical applications as it is representing everything from dialog to explosions in commercial theater, small cinema, and home entertainment systems.
The S12A MkII features selectable RCA and XLR analog inputs for flexible installations, and also offers a variety of parameter adjustments including gain, LF adjust, adjustable crossover, and delay so that it can be perfectly integrated into any audio environment. It also includes a 12V trigger input/output for power conservation and other applications. The S12A MkII’s impressive 700W amplifier is more than enough to deliver a gut-shaking 114dB SPL, and multiple S12A MkII subwoofers can be combined in a larger system such as a cinema screen channel.
