I have two attached to my couch but I only use them late at night so I do not have to run my sub too loud and I think is pretty cool.
But can adjust the vibrations, right?
No problem on mine; sure it works the same on all of them since they all seem to require an amp in betwwen the pre/pro and tactile transducer. You go into the trims for the sub channel you have it attached to and can increase that channel to get the desired effect. The one I got is probably one of the more expensive on the market. I did see one non-commercial unit [Earthquake] that was more expensive. The Sonic Immersion VT200 IBEAM Transducer is roughly 7" x 3" and perhaps 2" high; attachs w/10 wood screws into a plank crossing a couple of wooden supports in my 3 piece theater recliner. My chair gets great feedback, wife's chair ~15" away separated by the arm rest portion is mostly acoustically isolated because it's somewhat of a sectional on common metal frame. Really like it. Would have liked it better if I'd been able to snag a PA1 at $299 or better still at BF price of $199, but to no avail. Ordered 200 watt ice amp board and PSU online [backordered], plus case in route from China. Meanwhile, it's hooked up to my Carver M1.0T right channel. I'm considering buying a second Sonic Immersion VT200 IBEAM Transducer to hook up to the left chair and using the Carver left channel. The Carver will need to get connected to a wifi switch since it predates amp triggers and wake from sleep like subs have.
