In the Otica design, the servo 8" drivers are part of the speaker cabinet and function more like mid/upper bass drivers than a traditional subwoofer. With the Wedgies (Neo3 tweeter & LGK midrange drivers), they crossed at 200Hz and blended perfectly when properly dialed in. The same will be true when paired with the Neo3 tweeter and M-165NQ midrange drivers. The Otica with servo triple 8s will be a speaker with rock solid output flat to at least 30Hz. The triple 8s will produce a much higher performing speaker compared to 4 M-165s. However, this improvement will come at a cost as six 8" servo drivers and two servo amps will cost a lot more than eight M-165s.
Open baffle subwoofers, especially with Rythmik's direct feedback servo control, behave differently than traditional box subwoofers. Cone material and proximity to the drivers the subs are being crossed to also comes into play. Paper cone drivers can be crossed higher and the higher the crossover point, the closer the sub drivers need to be to prevent the isolation effect. Taking everything together, servo controlled, paper cone drivers, in the same cabinet right next to the midrange drivers they are crossing to will not have any localization effect.
