The Dipole15 was designed specifically for open baffle/dipole use. As open baffles typically require high excursion from the drivers, this driver features a large underhung motor with full copper sleeve on the pole. This combination means extreme linearity and extremely low distortion during high excursion use. The high Q and low Fs allows for the driver itself to be very efficient at low frequencies and have a very flat response down into the mid 20Hz range. This means no EQ is required to flatten the driver itself, only to compensate for the baffle rolloff. As with all of the TD drivers the Dipole15 has extremely low and linear inductance allowing it to play cleanly up into the midrange frequencies as high as 2KHz.

Due to the underhung motor design the power handling is lower than the other TD drivers. However, these drivers were intended to be used in multiples per channel when extreme SPLs are required meaning the power handling is right where it is needed. Due to the extremely linear underhung motor, this driver has some of the best midrange performance of any TD woofer. Available in dual 8ohm coils only, specs are with both voice coils wired in series.
