Sony introduced three new AV receivers. The claim to fame of both the STR-5800ES (130 Watts per channel) and STR-2800ES (100 WPC) is that they may be directly integrated with the popular Control4 home automation system. They may also be used with a variety of other automation systems. The third model, the STR-DA1800, does not have Control4 built-in. All three offer 4K upconversion, full WiFi, Bluetooth, Airplay, and Internet access features.

Though outwardly similar to last year’s VPL-HW30ES, Sony’s new VPL-HW50ES (available in October) is an updated design. It incorporates the same Reality Creation processing as the company’s flagship VPL-VW1000 4K projector, scaled down here for 2K operation. There’s a new Iris 3 algorithm for the projector’s advanced dynamic iris, for a claimed dynamic contrast ratio of 100,000:1. The light output is also said to be increased by 30% to 1700 lumens. The 3D transmitter is internal, and the 240Hz panel is claimed to reduce 3D crosstalk. There’s also a 2D-to-3D conversion mode and a 244-zone panel alignment feature to insure convergence.

While at $4000 the VPL-HW50ES is more expensive than the HW30ES (which remains available at a reduced price of $3000), the new projector’s price includes 2 pair of active 3D glasses and a spare projection lamp.

Sony’s launched its new XBR-84X900 84-inch diagonal LED edge-lit LCD set at its CEDIA EXPO 2012 press conference. With a native 4K resolution (3840 x 2160), it can display native 4K material at 24Hz or 30Hz, or upscale 2K sources to 4K. With its passive 3D glasses, it can also produce a full 2K 3D resolution to each eye (passive glasses in a 2K 3D set reduce the resolution of a 1920 x 1080 source to 1920 x 540). The set looked spectacular and will be available at selected Sony stores in November for $25,000.

Sony also announced two new flagship XBR-HX950 LCD flat panels: 55-inches ($4500) and 65-inches ($5500). The sets offer full LED backlighting with local dimming and are available now.

This is the SEAS driver referenced in the posting above.

There are specialty manufacturers that make various parts for loudspeaker drivers, and when ordering specialty drivers it is possible for a manufacturer of finished speakers to select the cone, surround, frame, voice-coil, etc. from various sources and have these parts assembled by a finished driver specialist. That's way it's possible to experiment with different configurations without the expense of fabricating the individual (very expensive) parts only to discard them if the results prove unsatisfactory.

That may or may not be how Wilson or any other specific manufacturer orders its custom drivers, only that it's possible. Note how the midrange driver used in the Sasha from Wilson Audio (and in variations in most of that company's newer speakers) at first glance resembles the driver from SEAS shown below. However, if you look closely the resemblance is mainly in the cone material, with significant differences in the dust cap, frame, surround, and presumably the internal structure as well.

GoldenEar uses these custom drivers in many of its speaker designs, including the air-motion tweeter.

Here are the beryllium cone drivers seen in the new, $50,000/pair 8T speakers from Status Acoustics and described elsewhere here.

Driver manufacturer SB Acoustics showed an array of their drivers, available both to manufacturers (either stock or custom) and DIY enthusiasts. Shown here is a new SB 8-inch woofer with an aluminum cone. It resembles (and may be) the woofer seen in some of the new Revel Performa line on display at the show and available in mid 2012.

I'm fascinated by the drive units manufacturers select or design for their speakers. Here and in the following entries I'll cover a few of them. Shown in the photo above are the midrange and tweeter in the new Aerial Acoustics 7. The midrange is made by SB Acoustics and the tweeter by Scan-speak, customized for Aerial.

Wisdom launched several new in-wall speaker systems that would be well-suited to a home theater setting, particularly one using a perforated screen. The demoed units were the P4i ($1500 each) and L8i ($5000 each). While neither could match the sheer majesty of the Wisdom LS4s, both of them (with a smaller Wisdom subwoofer) provided sound of a quality I never thought possible from small in-walls,m with none of the usual in-wall colorations. One caveat here is that the temporary walls used in the demonstration may not be typical of real walls, either in the size of their internal cavities (the Insights do not use a backbox) or in rigidity and lack of resonances (the walls here appeared to be made of MDF, not the sheetrock of most residential construction).
