Looking for some input here from someone that is "in the know" with JL products or have used these two series. I'm currently running 2 pairs of JL MX 770 and in my opinion they sound really good. Now I'm looking to add 2 JL subs into the system but I'm torn between the M and the MX. I'm not looking to win any contests or ripple the water. Just looking to add some more oomph to it. Anyone have some experience with the MX series that they can weigh in on? One more thing, they will be infinite baffle subs. I have no room for boxes and can't afford to lose any space.

I have the MX 10 in an IB configuration and I am happy with it. I also have it paired with 2 pairs of MX770 and adding a 3rd pair. I don't know how the M series would sound.

I don't have any MX experience but all my boats have JL M series love them. Installing a M700/5 amp and a single M10IB5 sub classic in the Talon today.

Is there any specific reason to use the M700/5 amp vs. M600/6 amp bridged with a 4-speaker 1-sub system?
