A lot of speakers use a very similar response, a dip in the 2-3khz range, and a bit of boost in the 8-10 khz range.
I have read that many like that sound, it keeps vocals and similar sounds from being "Too" forward and allows clarity at the upper end for listeners that have older hearing.
Not saying it is ideal, but I have owned speakers that were flat in the mids and also this type.
The "Dip" ones sound a bit recessed, but are more listenable long term for sure.
The ones without that "Dip" came across as the singer was right "There", but got tiring at higher levels.
The highs, listener dependent.
