NY Audio Show 2013

I was intrigued by the new MartinLogan Dynamo 1500X subwoofer ($1595), but even more so in a relatively humble accessory that M-L offers to buyers of their current subwoofers: the Perfect Bass Kit or PBK ($100), comprising a stand plus a USB microphone, the latter to connect between your woofer and your PC in order to optimize positioning and setup.
