Sony plans to introduce a lineup of high-resolution car audio products in December — just in time for the holiday season. The three items are: the RSX-GS9 digital media player ($1,499), the XM-GS4 four-channel amplifier ($299), and the XS-GS1 supertweeter ($199). These new products will join an already available line of front and rear speakers, two subwoofers, and a mono amplifier.
In addition to playing DSD files, the RSX-GS9 head unit upscales standard music files by using Sony’s Digital Sound Enhancement Engine (DSEE HX) and employs LDAC audio coding technology to facilitate hi-res streaming over Bluetooth when used with Sony’s SongPal App. The RSX-GS9 incorporates the ES9018S 32-bit audio D/A converter from ESS Technology and has three USB ports (one micro-B). The head unit has an aluminum faceplate with an OLED display, and all internal components are enclosed in a rigid dual-layer chassis, said to minimize resonance and interference.
The XM-GS4 four-channel amplifier has a rated bandwidth of 10 Hz to 100 kHz and variable low-pass/high-pass filters.
The XS-GS1 supertweeter — intended as an add-on for the XS-GS6921 rear speakers and XS-GS1621 and XS-GS1621C front speakers — has a 1-inch soft dome and can be installed facing the windshield to increase high-frequency dispersion.
