Actually, John... Bridgey... whatever I should call you.
I'll shoot straight from the hip on this one. The 4.5" drivers in the QS4s are a near perfect tonal match for the 6.5"s in M3s. I can throw test levels all around the room, and not until it hits my non-Axiom centre do I really hear a difference tonally. The presentation is a lot different (ye ol' quad pole versus direct radiating) but the tonal match is better than I would have thought. That STF-2, though... I EQ the hell out of it but it never sounds like the rest... it's all low and rumbly.
