LAS VEGAS - French company Devialet was showing off its Phantom Implosive Sound Center Tuesday night at Pepcom. This powered speaker system looks amazing and sounds even better. There's a caveat, though: listening to any speakers or headphones on a convention show floor is a terrible idea. It's just too noisy, but I was impressed with this device. The company designed them so that you can use from 1 to 24 of them together. They sync using Wi-Fi, and they're priced at $1,999 [price corrected] per unit. I have a lot of questions about the Phantom Implosive Sound Center, and I can't wait to test them out. In the video I posted to Instagram, the iPhone did a remarkable job of capturing the sound. Plus, you can see the subwoofers moving. Check it out.
