Mini Bass Shaker Dayton Audio TT25-16 PUCK Tactile Transducer Mini Bass Shaker 16 Ohm The PUCK by Dayton Audio is an inexpensive, small tactile transducer otherwise known as a mini bass shaker that is intended to be used in Home Theater, Gaming, and Auto Sound applications. This mini bass shaker has the unique ability to transfer low frequency sound waves directly to the listener by mounting the PUCK¿ to surface areas that a listener's body will come into contact with. Because the listener "feels" the low frequency, the volume of the overall sound can be kept to a minimum without sacrificing the audio quality. The PUCK measures a mere 3-1/2" diameter and 1" depth, nearly identical in size to an ice hockey puck. The small depth and diameter of the PUCK mini bass shaker make it uniquely suited for tight spaces and unobtrusive applications. 4 layer Voice Coil with 1" aluminum former. Four PUCK transducers can be wired for Stereo 8 Ohm Right/Left 2 channel wiring or as a 4 Ohm 1 channel system.
