Thanks for the reply guys, yeap, I actually took the AVR set, the
vsx-519v-k , full set 5 speaker s-ms800 and the srs3sw.

I've tried tuning everything, and for me, the sound is good enough. Except for the SW. I can't seem to generate a great deal of bass. even If i've tuned up the volumn on the SW, its still too low.

Even my previous hitb packs a bigger punch on bass. Is there any settings I missed? The manual really sucks big time. All I can tune is the db of speaker, distance and the size of the speaker. Are there any hidden configs that will make the bass better?
