Has anyone designed subwoofers using either the GR or Rythmik versions of the 12" drivers in a transmission line enclosure?
Why?
A transmission line (properly implemented) can increase a woofers output in a lower region where it is typical down in output. But the down side is large un-braced panel areas that resonant and color the music, a non-linear response curve, a boomy peak at the tuning frequency, and some group delay.
The servo subs play flat to 20Hz and -3db down in the teens in a sealed box and without any of those ill effects.
