No brainer. The 3.7i handily presents a more detailed and realistic sound stage. It generates much less room interaction but t is not going to do 110dB. So, if you are a head banger it is not the speaker for you. The Maggies are also more demanding of a good amp. Forget about any class D amp. Pass amps and the JC 1's sound glorious. Think class A.
Adding subs will give you low bass and clean up the Maggies a little but it will not get you more headroom. You should be able to do an effortless 95 dB which is as loud as I usually listen. The Maggies are line sources. You will need 4 subwoofer to match up right.
The Tektons are IMHO some of the worst loudspeakers ever made. They are made as cheaply as possible but they will go loud for a while anyway.
