[QUOTE="Uwe Riemer, post: 215049, member: 394"] So you basically ended with a tuning similar to the suggested B&C design, which is probably a compromise for using the 12" fullrange, where it might be better to have at least some low end. For Top only application you are still waisting potential low/mid output. So whenever you find yourself having problems with bass guitar or snare, you can remember my words, otherwise forget them :) . Of course it is easy to tune too high, which will also sound bad, thats the reason every nice curve of the simulation program needs to be evaluated by ear. Regarding the DATS drive level: Impedance is a moving target, because it changes with drive level and 10dBU are not enough to provide realistic measurement conditions for a SR speaker IMO. One last thing: You should look into that 300Hz peak in your impedance measurement_ This could be a sign of serious enclosure resonance [/QUOTE]
