None of the speakers Axiom makes will do thudrous bass without the aid of a subwoofer. While they provide good bass, even the m80ti's roll off at around 50 Hz, which in and of itself is extraordinary for 6.5" woofers. Sounds to me that something along the lines of an SVS sub (they are typically very violently powerful, even scary at times - lol) and a M22ti or M2i setup would be good for you .
