I'm not an audiophile so I need some help deciding between Klipsch Reference RB-51 and Infinity Beta 10. Both are bookshelf speakers about the same dimension. The RB-51 has 5.25 woofer and a 1inch titanium tweeter. The Beta 10 has 1 5 inch woofer and a 1 inch CMMD weeter. Sensitivity for the Beta 10 is 88db and the crossover 3,400Hz. The RB-51 sensitivity is 92db and the crossover is 2000Hz. This is all greek to me. I watch mostly movies and I have a 12inch JBL sub. These speakers will be fronts. I currently have Athena AS B1.2 for fronts. I have an Onkyo 705. Which speaker will sound best with the 705 and movies?
