I have a Klipsch SC.5 center speaker. I also recently upgraded my towers to the Klipsch RF-5. Now my center speaker sounds drowned out by the sound from the towers. A salesman told me I'd need to get a more powerful center. I've been looking at the Klipsch RC-3II. Should that fix my problem, or do I need to make an adjustment on my receiver? (I do have the volume for the center turned all the way up on my receiver). Any help is appreciated.
