0.3% of music worths a lot
A normal listener will prefer
A good set of headunit and Speakers or Componenets
While Bass Crazy people (like me)
will spend money on that
cause that 0.3% of music also bring any one to COMPETETION levels
Bass the that sort of music`s spectrum
to feel vibration ( a mechanical force )
to feel Cut off noise from environment ( play any bass song will let you hear only bass with other some MID/Treble by speakers ) when bass line drops of , you again hear noise from outside
to rumbling the Ear ( is really a fun for me ) which tells Bass is too powerful
to Enter A Competetion LEVEL , getting high DB SPL as much they can
this is why
people uses 15" x 10 , 18" x 10
One of the GUYs (Pioneer`s World Record )
Used 115000 Wrms power in his Van to acive 180Db , thats ROCKET Lauching Sound Pressure
(some 14 tsw 5000Wspl , 24Amps etc
now you can think how much people spends for that reasons
