mY subwoofer is the one beside the left tall tall JBL speaker....
i using 12" subwoofer, this one is Infinity dunno wad model from harmon kardon,
i have another one is infinity 12" oso, infinity subwoofer is good for low bass frequency respond, i tried the subwoofer test song, it responded at 20hz..veri good
If you notice, i put mine in a 'corner' wid things beside it, it is not the proper place, if u like bass like me, u shld put the woofer in a corner, so the bass will reflect, the volume of the woofer can be adjusted, as well as the crossover frequency.
Mine subwoofer onli cost aroud $400+ to $600+ the bass is still quite good, enough for me to get complain from neighbour
For my subwoofer, i cannot put it on the desk, if you see most of the subwoofers, it is placed on the floor. u shld get a high end, it onli cost above $800 or more.....
