Yea, if you have no sub, then feel free to leave them as large and see how they do. I remember hearing Randy's (SirQuack's) M80s a few years back with no subs turned on (he had like 3 in the room) and I couldn't believe how well they did as "large" speakers. I swore that at least one sub was turned on.
