1) High Resolution HR4
The Ocean WayAudio HR4/HR4S Reference Monitor is an accurate, wide-dynamic-range, sound-delivery system for the
professional listening environment. It is 25.5” wide and features an integrated 2-way dual-horn, directivity-control loudspeaker
that can be placed as a pair in any environment to provide an exceptionally-accurate and revealing stereo monitoring
experience.
At the heart of the acoustic design is HR4’s dual/hybrid waveguide system. Its unique design was engineered utilizing 3D
modeling and then CNC machined from composite materials. This accurate process allows for the creation of geometrically-
complex surfaces that are accurately-matched for delivering detailed imaging.As a result, the HR4 delivers a stunning 100 x
40 degree dispersion pattern over a very wide audio range. An exceptionally wide “sweet-spot” is revealed with rich detail
across a broad area of the listening spectrum. The consistency of its stereo image, even at the far corners of the room, is
achieved due to the highly consistent directivity response of the speaker system. This is often a delightful surprise to the
listener in light of what is available today.
The HF driver is a high-definition silk fabric dome design with excellent mechanical linearity. The LF driver is a geometrically
reinforced aluminum cone with a vented cast-aluminum chassis yielding optimum strength and high-power linearity. Combined
with a rock-solid wood/composite cabinet, the system is voiced to provide an undetectable crossover 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.
For those who wish to achieve even greater SPL, we offer a 3-Way version with dual 12” sub-bass cabinets –entitled HR4S.
HR4S delivers 25 Hz to 25kHz @ 118 db.
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.
