I don't know of any monitor, but one, that doesn't need a subwoofer. As low as my M20s go, a sub is needed. I am waiting on Harmonic Precision's new monitor, the Caravelle. Subwoofer? I don't think so? Can't say this first hand; though the feedback, from reliable tympanics, is nothing less than phenominal. Forget about comparing the Caravelle to other monitors. We're talking comparable to floor standers of a very high $$/quality level. When I get these babies and listened up, I'll give you the low down. This is a very exciting, one of a kind speaker, that'll be here soon. peace, warren
