typically i've found flat suits all of my music at the levels i typically listen at. around 100-110db C weighted.
What annoys me with my grandprix is, In my truck everything sounded good. in the GP i'm constantly changing EQ settings to make it tolerable on different songs with the stock system.
that and alot of techno doesnt sound right to me through passive crossovers. Maybe its just me and i'm full of crap but, I swear alot of synth sounds sound far sharper through a direct coupled amp hooked directly to the speakers "no caps"
its also what made me stop collecting\using highend tube amps.
Even tho a speaker obviously cannot reproduce a square wave or sawtooth wave properly, having inductors and caps in the circuit seem to make things a lot worse.
IMO, theres nothing like a song like DJ Tiesto Parade Of The Athletes : Euphoria. On a quality direct coupled biamped or triamped system.
Or a more common person\group , Infected Mushroom.
