I am looking to upgrade my HT system; currently have the yamaha 6090 http://www.jr.com/JRProductPage.process?Product_Id=4139490&JRSource=googlebase.datafeed.YAM+HTR6090BL
Want to go with the RTi10s for the main and the Fxi3's for rear. Looking for suggestions on a sub and center speaker (center has to be 5 inches high max to fit in cabinet). Also, will my receiver be strong enough to drive these Polk's?? Thanks for all suggestions.!
