The big speaker you always wanted is now affordable.

The Ocean Way Audio HR3.5 is based on the highly acclaimed HR4S studio monitor. This stand-alone or soffit-mounted monitor speaker delivers a frequency response of 20 Hz to 22 kHz with a solid SPL of 120db. The HR3.5 Reference Monitor incorporates an integrated 2-way dual-horn system with a l” HF and 8″ MF drivers, mechanically time-aligned with twin 12″ sub-bass drivers per channel. State-of-the-art A-4100 amplifiers provided by OWA power this speaker with both analog and digital inputs, 96 kHz and 24 bit sampling, tri-amped delivering 3,400 watts per channel of pure power. At the heart of the acoustic design is OWA’s geometrically-complex, stone-casted dual/hybrid waveguide system.

The system delivers accurately-matched and detailed imaging with our signature unusually wide 100×40 degree horizontal and vertical dispersion, yielding a massive sweet-spot across a broad area of the listening environment. The consistency of its stereo image, even at the far corners of the room, is due to the highly-consistent directivity response of this unique speaker system.

Dimensions are 43″H x 17.5 W x 25.5″ D. Amplification is conveniently rack-mounted, allowing either soffit or free-standing installations. 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.
