Arylic BK501/651 bookshelf speakers integrate high-end AMT tweeters (Sponsored)

Arylic is better known for its connected audio devices such as the Arylic A50+ wireless amplifier or S50 Pro+ wireless stereo pre-amplifier, but the company has now launched its first passive speakers with the Arylic BK501 and BK651 bookshelf speakers that integrate high-end Heil AMT (Air Motion Transformer) tweeters. The BK501 is a pair of 5-inch speakers with 80W peak power, while the BK651 is a pair of 6.5-inch stereo speakers delivering up to 100W peak power. The specifications table below shows how both models compare. Both speakers support Treble up to 40kHz to feel detailed treble clarity and brightness, 180° wide soundstage, feature a fiberglass mid-woofer and received FSC Environmental Certification. Both designs include an MDF (medium-density fiberboard) cabinet with 15mm thick walls for the KB501 and 18mm thick walls for the BK651. Arylic says the Heil AMT tweeter found in its speakers uses a folded Kapton ribbon diaphragm […]

Banana BPI-P2 Pro headless SBC features RK3308 CPU, PoE Ethernet, WiFi 5, audio jack

Banana Pi BPI-P2 Pro is Rockchip RK3308 quad-core Cortex-A35 SBC for headless applications with a PoE-capable Ethernet port, WiFi 5, a USB port, an audio jack, and two GPIO headers for expansion. You may think the Banana Pi guys have gone crazy by calling such entry-level level SBC “Pro”, but that’s because the company previously released the BPI-P2 Zero and BPI-P2 Maker single board computers based on Allwinner H2+ quad-core Cortex-A7 processor, so the BPI-P2 Pro is indeed an improvement albeit with some caveats. Banana Pi BPI-P2 Pro specifications: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor @ up to 1.3 GHz with built-in VAD (Voice Activity Detector) System Memory – 2GB LPDDR2 SDRAM [Update: According to Rockchip RK3308 specifications, the maximum memory capacity is 512MB, so Banana Pi may have meant 2 Gbit instead, meaning 256MB of RAM]. Storage – 8GB eMMC flash, microSD card slot Video Output – […]
