I have recently purchased the CM5's and CMC2 and I am struggling to get the center to have the same dynamic range as the CM5's? I am using a Yamaha RX-A 3000 to drive the CM's. In HT mode, I cannot seem to get a good sound quality. I have not tried a blue ray yet, just been testing off of cable tv. The CM5's sound great in stereo. But HT has me scratching my head.
I also have CM5 fronts and a CMC2 center. I am really happy with the combo for HT. I ran with a phantom center for a few months before adding the CMC2 and I can understand where you are coming from as it really alters things quite a bit.
The CMC2 is a big speaker relative to the CM5s. I notice it especially in the mid-bass. The CMC2 really "hits you in the chest" during action sequences in a way the CM5s just aren't capable of. Part of what you are hearing may just be the process of your ears/mind adjusting to the added dynamics and power of your overall system.
To adjust the overall balance to your liking I have a few suggestions:
1) Experiment with speaker placement if your room allows. Speaker placement - even a few inches - can really have a large effect. Try adjusting distance of the CM5s as well as toe-in to see if you can dial in the balance that sounds right to you. If you have your center in an AV cabinet it may help to put it on a stand, or angle the front up slightly.
2) Experiment with the foam port plugs in the CMC2, especially if your center is in an AV cabinet or if the rear of the speaker is less than ~2' from the wall. This will cause the bass to roll off and may sound more balanced with the CM5s for you.
3) Try adjusting the volume trim in your AVR and set the volume of the center down a couple of db.
