Maggies and subwoofer integration

Thanks for your replies, but I'm still curious about the benefit of adding a sub if it's just augmenting the full range, and not taking over bass duties entirely off the maggies. 

My Velodyne is the VLF-810.

I don't have the option to set slopes with my system. No external crossover or DSP. I'll be just adding the subwoofer via the Schiit Saga+ extra output, and try to integrate as best as possible with the maggies. Possibly bass traps if needed or sound dampening in the future. . 

Thanks guys. Definitely a subwoofer adds and enhances the soundstsge. I'll probably set it to 50-60HZ and low gain as possible. Don't want it bloated and boomy. Plus 11x13 room in an apartment. 

Sounds good Johnto. Kind of similar to my approach and the experiment I'll be undertaking. 50-60HZ and low volume to begin with. Take it from there. I'm definitely not a bass-head and want this room to be the classic, acoustic, Jazz room vs my other room with  harder music. But came upon a great deal for this Subwoofer, and said to myself that it can't hurt to try it with speakers like maggies. 

That's the route I'll be taking anyway if at all after experiments. No crossovers or added/replaced components at the moment. To begin with, these maggies might be gone soon as the right one is not great,and refurbishment is as expensive as new ones, and I most definitely don't have the patience and time to perform it myself.
