They can get about as loud but had just a bit less harmonic distortion, 15 mk2s or Rythmik F15HPs. However both subs are very clean and the audibility of distortion is very unlikely in either one, a LOT easier to move around and setup. Ultras are definitely going to have greater performance from 16 to 30 Hz, at 12 Hz and below I would expect the S1 to have more output. One more thing, 15s don’t really have an advantage.
