Because here many have confirmed my experience, here only as a supplement to what my opinion is worth mentioning: The parametric equalizer is disappointed engineer, since the frequencies of sound-fixes to be set and only roughly possible only in third increments. The iOS / Android app can not also. Even the figure of merit can only be set in 3 closely spaced values. For the optimization of mediocre series speakers but that would be required, and for Alpine without much additional effort possible - it would just be a change in the software. But as other manufacturers offer much less, the 178BT is currently probably the best compromise.
The front panel is easy to remove, the Restarting somewhat fiddly and actually takes both hands. The other manufacturers can better.
