You kind of answer your own question. If money were no object, you need bass traps and an EQ. Make sure you are cutting off your main speakers above 80 Hz.
Good free software is Room EQ Wizard (Google it), but there is also Audio Tools for android + a $27 imm6 microphone from Dayton:

You'll probably also need mini to RCA cables for the test signal.
