Hi, I tried all your guys suggestions but i am still having very little bass in the M80's.
GET AN EXTERNAL POWER AMP! I got an amp while I was still using my m22ti and it did a great difference in the sound (around 30% improvement). I was hearing base from them that I never heard before. I can't imagine running my m80s without the amp. If you want an impressive audio experience, an amp is mandatory.
Take your car and go to your nearby music shop. Rent a Behringer amp (I have an EP2500) for the w-end and see for yourself.
They have plenty of choice: QSC, Crown and more. They are not expansive to buy and well rated (my Ep2500 was 400$cdn).
Don't hesitate and rent it!! you won't regret it. You will need a pair of RCA to 1/4 cable.
