How many times have I written lately that the only good thing about the Q100 is the 5.25" coaxial Uni-Q driver?
Everything else needs to be improved, starting with adding mass + damping.
Listening must be done at 40º-50º, that is, off the axis.
The bass-reflex can also be retouched, as I did for quite some time (now it is as before, with the same diameter).
The ideal is to have the rear bass-reflex like the R100 or the Q150 but then they need more distance to the wall, one of my limitations.
And with that spinorama, the logical thing is to retouch the frequency response smoothly, thinking about how it will be heard / measured at the listening point and not on the axis, which is why I have not yet modified the crossover, adopting the one designed by Zvu, preferring first to experiment with the improvement of its components. For now, minimum phase PEQ + rePhase -> convolution filter.
Also, that new sounds fatal, without bass, which is why I was about to return them.
