The others are right. You can get lots of satisfying bass out of maggies, even the 1.6. I have to make sure the rest of the system is up to the task first. amp (most important with maggies), preamp, source, power, resonance control, and acoustics. You might need more neutral equipment (ie, firmer grip on the bass). That's going to sound more neutral than adding a sub. That's one of the reasons I plan to change my preamp soon. I won't need the sub after that point, really. I know, I've heard my system with a more neutral preamp, and I am loosing loads of bass with my current pre. It's just so darn lush.
For you, sadly, it might be the Marantz SACD. Sometime Marantz gear has a softer house sound. It's likely not known for it's prodigous bass output. I'd either consider mods for the marantz or go in a different direction if I were you. I know we hate to receive recommendations to replace equipment when we post like this. Especially if it was so lovingly selected by ourselves. That's why I hesitantly make this suggestion. but I feel it's the right one.
Also, we need to ask if you're "trying to cave in your chest with bass?" If you are, you aren't going to get it with maggies. Not unless you run a real moster sub (or lots of monster subs). But if you're looking for just tad more, I think the maggies are capable of that on their own. Try a bigger amp first.
