Ocean Way Audio HR3.5 Reference Monitor - Single – No Longer Available

Stand-alone or soffit-mounted monitor speaker based on the highly acclaimed HR4S monitor - 20 Hz to 22 kHz frequency response with a solid SPL of 120 db
MFR# HR3.5

Product Description

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 120 db. The HR3.5 Reference Monitor incorporates an integrated 2-way dual-horn system with a 1” HF and 8″ MF driver, mechanically time-aligned with twin 12″ sub-bass drivers per channel. Three OWA-supplied state-of-the-art amplifiers per channel 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 OWNs geometrically-complex, stone-casted dual/hybrid waveguide system.

The system delivers accurately-matched and detailed imaging with Ocean Way's 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. Ocean Way carefully selects and matches each set of components, getting them as close as possible to achieve their high-performance standards.

The process could easily be compared to building a fine musical instrument.

Please note: The HR3.5 requires the Ocean Way Audio A-4100 amplifier and voicing module (sold separately) to function.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
