The detail’s unmistakeable: Sony introduces two new High-Resolution Audio speaker systems

Press release   •   Sep 03, 2014 16:49 CEST

High-Resolution Audio brings you music as it’s meant to be heard – with all the revealing clarity and emotion of the artist’s original performance. Two new speakers from Sony let music lovers experience High-Resolution Audio at home – reproducing concert hall quality without crowding your living room. The 3-way SS-AC3 and 2-way SS-AC5 are engineered with an uncompromising focus on reproducing natural, musically-engaging sound from today’s High-Resolution sources.

Both models offer audiophile-grade listening, with several design innovations from Sony’s acclaimed AR and NA ES Series speakers.

SS-AC3 3-way 6-driver floor-standing speaker

From the most intimate jazz ensemble to the slam of a hundred-piece orchestra – you’ll treasure the details of every musical moment with the SS-AC3. This 3-way floor-standing speaker incorporates an immensely strong 30mm baffle board that’s firmly joined with the rear enclosure, reducing internal vibrations to minimise unwanted colouration.

Tightly-defined, commanding bass comes courtesy of a newly-developed 130mm woofer that features a rigid aluminum diaphragm. The mid-range unit features a pressed paper cone diaphragm with spiral grooves that suppress resonance and help reproduce extremely smooth sound, particularly in the critical mid- to high-frequency region.

Mid-range and tweeter units are housed in their own acoustically isolated enclosure, separated from the woofer’s cabinet space with their own reflex port. This two-part design reduces the effects of air pressure from the low-frequency driver that can interfere with uncoloured reproduction of crucial mids and highs.

Sony’s innovative I-ARRAY™ System supplements a 25mm soft-dome main tweeter with two 19mm soft-dome assist tweeters. This combination of three high-frequency drivers improves dispersion of expressively-detailed highs, widening the ‘sweet spot’ so listeners anywhere the room can enjoy an uncompromised musical performance.

SS-AC5 2-way 4-driver bookshelf speaker

SS-AC5 is a 2-way bookshelf speaker system whose compact size belies its formidable audio credentials. Like the larger SS-AC3, it features a specially-shaped baffle board that damps vibration and resonance for remarkably pure, uncoloured sound.

The dedicated 130mm woofer is partnered by Sony’s I-ARRAY triple high-frequency driver, for a total of four drive units in a space-efficient enclosure that won’t swallow up living room space.

Two rear-firing bass reflex ports boost low frequency power and articulation for a satisfyingly extended, accurate low-end.

The new SS-AC3 and SS-AC5 High-Resolution Audio speaker systems from Sony are available in Europe from Autumn 2014.
