I agree with all this.A scoop style basshorn will have this 2nd harmonics then.I knew they were nonlinear-but didnt see how it affected the output.
So many say they like the sound of B*ssmaxx scoops,but I cant see how.
The only PRO basshorn ive heard is the martin WSX,which i thoroughly enjoy pants flapping SPLS everyweek almost -down at the closest club with 2 of them!-too bad the muddled midrange ruins the sound!
Have you seen TCsounds '46mm Xmax' driver?it has ultimately flat BL curve!
The BL curve looks like some one has clicked 'linearise' on computer and theyve managed to produce a reality of this!!!
