The BTL Series does what others cant. It allows you to tailor your subwoofer for your exact extreme SPL needs. Starting with our standard double stacked motor and 8 layer flat wind voice coil, you can tweak things with a variety of options. Need more power handling? Add a chamfered pole or axial cooling channels. Need incredible Xmax to feed your 160dB at 20Hz obsession? Add a third magnet and our extended length coils (26mm of Xmax). With over 20 different options to choose from, we can build the exact sub you need to fuel your SPL fire.
