Absorption ,Absorption, Absorption. Bass traps in the corners of your room. If you are a Diy person buy some Johnsmaville 814 2'x4' acoustic panels and cut them into triangles and stack floor to ceiling. I did all 4 corners of my room. Also a wall of the panels behind the speakers.
The bass probably quadrupeled. And the added bass makes the mids and highs better too.The highs are less forward.It just adds weight to all aspects including sounstage depth and width . My system does not even sound close to what it did without the room treatments.The best $700 ever spent .Like night and day difference. You have no idea what you are missing. I read people saying to use houshold items for absorption and diffusion and it is not even close to the real thing.I could go buy a bigger better amp/preamp and not get the same results as what the treatments did. also made some knockoff stand out of 2x4 's for $20.00.You will notice better bass with them.
