Certainly you've heard of the bass shaker concept
by now, right? If not, here's an alternative from Crowson that should make things crystal clear. The firm's new Shadow, which is obviously targeting the custom install market, gets bolted beneath any theater seat in which more bass is desired. When hooked up, the "Tactile Motion" feedback provides the wondrous feeling of bass without the hearing loss associated with cranking things to 11. Additionally, each chair can be controlled independently, meaning that some viewers could experience more rumble than others. Sadly, there's no mention of a price, but we're sure you can find an inflated one by phoning up your nearest HT dealer.
