Regardless of what is producing the bass be it sub or TL speaker, the output below the Schraeder frequency is at the mercy of room dimensions. Denying this is fool's folly and no pair of speaker can overcome the nodes and peaks of a room's dimensions unless their placement was designed into the room's dimensions.\n\nAccuDefTechGuy, I suggest reading Dr Toole's book on acoustics. Consider yourself lucky my friend for not having bass problems with your towers. You got lucky with your speaker placement with respect to your listening area and room dimensions.\n\nI could place your speakers in my travel trailer where I have my sub located and if I walked to the TV screen, the bass would vanish just as it does for my sub.. Luckly for me, I dont sit inches from my screen but about 8 ft back and at that location, I get plenty of bass. Placement of subs in a room given room geometry\/dimensions matters. Its got everything to do with physics and nothing to do with jealousy.
