The Treis Series shallow mount subwoofers are designed to deliver true subwoofer sound in a form that has a mounting depth of 3.54'. Alphasonik engineers recognized that there are scenarios where you just can't fit a full size subwoofer behind the seat in a pickup truck, in convertibles, in the trunk with golf bags, strollers, or whatever other assorted goodies we drive around with. Other shallow mount subwoofers in the market are not able to deliver true subwoofer performance, they are more like mid-bass drivers, unable to play those truly low notes that make owning a subwoofer fun.
Design
The Treis series was designed with a Spun aluminum cone fore accurate and ground breaking bass. Also, Alphasonik engineers added EPDM Surround for Enhanced control at Extreme Temperatures.
