The Bowers & Wilkins\u00a0Panorama soundbar has been around for nigh-on three years now, so it's just about time for a refresh, don't you think? And, low and behold - that's exactly what the speaker company has gone and done.The Bowers & Wilkins Panorama 2 is claimed to offer a "dramatically improved" acoustic performance over its forebear. It has all-new proprietary drive units, with low frequency drivers featuring\u00a0improved linearity to the benefit of dynamism and lower resonance. While the mid-range drive units offer wider dispersion characteristics, expanding the virtual surround sound.The tweeter has been improved to, in order to suit the new mid-range drive units.Inside the bar, there are nine drive units in total, five used for the centre speaker; two subwoofers, two mid-range drivers, and an\u00a0aluminium dome tweeter which features the firm's\u00a0Nautilus tube-loaded technology.The other four provide the stereo\/virtual surround scape. They're each located in their own enclosures and\u00a0powered by six class-D amplifiers. Total\u00a0power output is 175-Watts.There are three HDMI inputs on the Panorama 2 and one output, so it can serve as an entertainment hub\/switcher. You can also add a separate subwoofer to really broaden the soundfield.Bowers & Wilkins has also improved the on-screen display for the unit, and there's now a proximity sensor on the front which illuminates a control panel when you reach for it.The soundbar will be available this month for \u00a31,650.
