![]() ![]() Or, if all that seems like a lot of work, you could just get a D-Box SRP-230 Motion Platform to put under your existing sofa, along with a Series IV-BD Motion Controller to tell the SRP-230 what to do.ĭ-Box Technologies is a Canadian-based company that’s been working on the notion of motion for the last 12 years or so. Just as importantly, though, is that you’d have to create a “motion track” containing instructions that tell the mechanism when and how to move the furniture in conjunction with the onscreen action. First, you’d have to build a mechanism that can move your seat(s) in specific directions, such as up, down, or askew, rather than making them simply vibrate. To simulate the effect of a speed bump or a sudden stop requires something more-two things more, actually. ![]() Even the best tactile transducer will sit motionless during these scenes if there is no bass present in the audio. While watching a movie, you see all kinds of movement that has little, if any, connection to the bass in the soundtrack: planes fly through turbulence, automobiles bounce from potholes in the road, boats at sea rock back and forth, and, well…you get the picture.or the feeling. There are devices, however-often called tactile transducers or low-frequency actuators-that are designed to be attached to your couch or chair and vibrate the furniture’s frame in correlation with the amount of bass in the audio signal.Īssisted vibration of furniture can certainly add to your perception of bass response, and-done judiciously-can make whatever you’re watching or listening to more entertaining and immersive. Not everyone is fortunate enough to have a subwoofer, such as JL Audio’s monstrous, plasterblasting Fathom f212 (reviewed in Home Theater, April 2012, and at ) that can move everything in the room. These are sensations that you feel more than hear. For movies, it’s especially enjoyable when your subwoofer has enough spunk to cause the floor under your feet and the seat under your butt-and even your body’s chest cavity-to vibrate during those massive, over-the-top Hollywood explosions or through the low rumble of an earthquake. If you want loud, low bass, your woofers are going to have to compress a lot of air. When it comes to subwoofers and speakers, air movement is of particular import. There are, and have been, lots of movements in the world: political (the Tea Party and Occupy Wall Street), social (abolition, women’s suffrage, and prohibition), artistic (Impressionism, Dadaism, and WTFism), and of course, bowel (but I digest…er, digress). Can be used for simple bass enhancement of music.Price: $12,000 as reviewed At A Glance: Industrial-grade actuators
