Porsche Exhaust Soundbar Specifications
From 0 to goosebumps – in a single sound curve. The strictly limited-edition (500 pieces) 911 Soundbar 2.0 Pro, made from the Original Porsche 992 GT3 (992) exhaust system. The 2.1.2 Virtual Surround Sound System features 300 watts of system power, 4K compatible HDMI ports, Bluetooth 5.0, Dolby Atmos DTS-HD, streaming with Apple AirPlay 2 and Google® Chromecast built-in for multiroom. The Soundbar is equipped with in-room multi-channel streaming technology that connects with the 911 Soundbar Special Edition, the 911 Soundbar Final Edition as well as future new Porsche Originals sound products. It can be hung on the wall or placed on the base provided. Made in Germany.
It’s hardly a secret that Porsche 911s sound good. It’s a hefty part of the not-so-secret sauce, after all: the fact that at a certain part in the rev range – near the top, naturally – the flat-six engine in the back actually starts to sound musical. And the most talented aural performer is, coincidentally enough, generally the most talented… well, performer: the GT3.
So you can rather see the A to B of building a TV room soundbar using the actual exhaust from a 992 GT3. It’s certainly not the lines we’d think along – or even attempt to sell as a good idea to a spouse – but you could definitely accuse it of having logic in there somewhere.
And of course, being a modern audio device, it has all the necessary neologisms, initialisms and decimal-pointed numbers to work as more than an automotive art installation: 2.1.2 virtual surround sound, Atmos DTS-HD, Bluetooth 5.0, AirPlay 2 and 4K compatibility. And if all this made as much sense to you as ‘Y2K compatible’, then a) hello, fellow old person – hope your knees are in better shape than ours, and b) you’ll be able to plug this into your new fancy TV and get 300 watts of Michael Bay booms and Hans Zimmer bwaaaaahs. You’ll also be able to play music from pretty much any music-playing device you have around the house, either over Wi-Fi or Bluetooth.
