Hi Mike
This little chart I whipped up should help get a grip on the tuning (18 combinations is a lot, trust me it made my head spin too!)
Just to break it down, the back filter essentially modifies the bass and the nozzle affects the treble.
[size=inherit]Back filter in order of DECREASING Bass extension and amount [/size]
| Front nozzles in order of DECREASING Treble extension and amount
|
Red > Black > Blue
| Blue > Black > Green > Gray > Red > Pink |
So
Red Back + Black nozzle will give you the most sub bass with full treble extension (not as full as blue nozzle theoretically). After trying the combo with the song Fall of an Empire by Celldweller, I can confirm that is the case.
For future reference, say you are in the mood for less treble just go down the nozzle filter sequence till you are happy with the amount of treble (
Blue > Black >
Green >
Gray >
Red >
Pink) and vice versa. The same goes for bass, if you want less bass (
Red > Black >
Blue) go down the list of filters till you are happy, and go backwards to increase the amount of bass extension.
Looks tough at first but once you try all the combinations you will find a couple that you love and mostly stick with that haha. That was the case for me anyway
I have owned a few so called TOTL iems in his hobby and I am not one prone to hyperbole but the LZ A4 is performing at such a high level it is about as
end game as it gets. Just makes me laugh that we are getting all this at 200 USD (which is peanuts compared to what the big boys are charging.)
