OK I'll start by saying this is my first post. I am trying to purchase the best home theater for my money. So far I have bought a Samsung UN55B8000 55-Inch LED TV. I have old components hooked up to it now(Polk surround bar and Onkyo TX-SR604 receiver), but am looking to upgrade. I'm considering the Pioneer VSX-1020-K receiver and the JBL L880's as left and rights and Prepac Ferentino 60" Flat Panel TV Stand in Black - BFG-5924 for my TV stand. Because I want this TV stand my center speaker needs to be 18.75" or smaller to fit in the stand. So what I'm really asking is what speakers would be recommended to compete my 7.1 system? Any suggestions or replacements would be much appreciated! Thanks.
