The TruAudio speaker lineup grows with with additions covering both residential and commercial markets-- the OL-70v 2-way outdoor and the CL-70v in-ceiling speakers.

The OL-70v is, as the name implies, rated at 70V but is switchable to 8 ohms impedance if required. Taps are 2.5W-25W selectable, with a large ABS cabinet housing a 6.5-inch polypropylene MF/LF driver and a 1-inch silk dome tweeter.

One can mount the cabinet either horizontally or vertically. An aluminium grille attached with anti-corrosion brass fittings protects the weather resistant drivers, and should be able to stand more damp and humid environments.

NAD Electronics reveals a trio of AirPlay-enabled audio products-- the D 3020 DAC/Amplifier, D 7050 Direct Digital Network Receiver, and D 1050 USB 24/192 DAC.

The D 3020 is a DAC/amplifier modeled after the late 1970's NAD 3020 integrated amplifier. It features built-in 2x30W Class D amplifier, stereo AptX Bluetooth connectivity, asynchronous USB input, subwoofer output, separate embedded headphone amp (with volume control), x2 optical, x2 coax digital and x1 analog inputs, remote and, of course, AirPlay streaming capability.

NAD describes the D 7050 digital network receiver as the first successful closed loop digital amplifier in the world-- meaning it compares output to input before compensating for any difference to achieve "perfect" output. DAC performance is 24/196 and the 2x50W amp uses pulse width modulation (PWM) and Direct Digital technology.

Accessory Power launches the GOgroove BlueSync LX-- a 2.1-channel speaker system complete with Bluetooth connectivity, full-range satellite speakers, built-in control hub and LCD display.

The speaker configuration features x2 satellite speakers with 3-inch drivers and a 4-inch high-excursion subwoofer. It connects to mobile devices via Bluetooth, as well as wired devices and microphones via aux-in 3.5mm jack.

The subwoofer features an LCD display, while the included remote allows for equaliser, playlist, Bluetooth sync and power control.

Thiel announces an update on CS1.6 2-way floorstanding loudspeaker-- the CS1.7, leveraging on technology from the flagship CS3.7 to establish what the company claims are "new standards for resolution of detail, imaging and staging, dynamic capability and tonal purity."

It features an optimised CS1.6 tweeter, with voice coil, magnetic circuit and aluminium diaphragm reworked to increase linearity and lower distortion. The "star" diaphragm in the aluminium woofer is produced via laser measurement technology, the voice coil and magnetic structure enable the driver to operate as a piston through a greater frequency range and the crossover network maintains phase and time coherent nature.

The cabinet is 2.5cm thick and the baffle is 5cm thick, providing plenty of rigidity and inertness, and even the magnetically-adhered grille is engineered to prevent diffraction.

Measuring 24x30x92.4cm (350x380x97.7cm with outriggers), the loudspeaker ships with levelling feet, and Thiel also offers an optional brushed aluminium Outrigger base to improve stability on most surfaces.

The CS1.7 is available now.
