I recall Joe mentioning an exorbitant amount of funding was spent on the complete engineering of the IBS system, maybe several mil or more? I agree that the components are cheap, but I think you will be charged a healthy premium (likely across all models, even those without IBS) for Honda to recoup those R&D costs...The upside is that very little engineering was required for the in-bed speakers - there's not much to engineer. Surface transducers ("exciters") have been around for years and are very cheap to manufacture. Consisting of only a coil, magnet, and frame, they are basically speakers without cones. It's a safe bet that the entire system consisting of 6 exciters, an amplifier, wire, and software for the infotainment system probably cost Honda less than $100. Of course, I think most of us will agree that that $100 would have been better spent elsewhere.
