    Only other items in the system right now will be Crossfire BMF-MB6 6.5" midbass doing rear fill. Proper sub will eventually be added, but not soon. Regardless, I'll just buy a dedicated amp for that anyways.

    Not a fan of the Infinity's... they are lacking in the midbass area quite a bit.

    Still solid speakers... all around good products.

    The 60.7CS Infinitys seem to have the "best" frequency response range in terms of midbass when compared to other Infinity comps. Reference series go down to 53hz, while the top end Perfect 6.1's go down to 75hz.

    I can't say I have listened to all of the above, but just throwing some numbers out there. (I am also pondering the idea of picking up the 60.7CS's.)

    they must have changed drastically in the past 3 years(when we stopped selling them.), because infinity used to be very strong on the midbass side... infact we'd sell them to people that did not plan on adding subs to their car because of this fact.
