welcome shin
you remind me of shin from dbz ! lol
take the farfield files of xaero ma loud and rest of the files from w880 acoustics
then the backspeaker volume will increase ! and the player volume will remain same
if u wanted more bass then xaero ma loud and check out pedro ps acoustics
i think bass is really enough .. we lack treble !
Sokre i will upload S_E_EUROPE FS for K550i on Dec 1st !!
i guess you have S_E EUROPE FS for W610i !
see this for acoustics
thanks to kelvin he gave me the links
