New in the shop: these awesome folded horn subwoofers.
A classic design using a motor and driveshaft to move very low frequency, delivering bass under 40Hz like no conventional voice coil/magnet transducer.
This is the original design that was copied by PK's Trinity line.
The dual 15" cones in an isobaric chamber provide an even frequency response down to 28Hz, and sound down to 14Hz, with unparalleled efficiency.
Come into the shop and check these monsters out.
