No, I didn't mean the Jbl' should win on sound quality, but that the electronics are likely to be superior; which reflects on the price point. I'm not accusing you of anything. LOL.

I said go with the speakers you prefer sound wise. The emphasis appears to be entertainment, and the 305' may be too neutral and dull for that purpose. They're intended for near field listening.

The other listed speakers are likely to be superior to the Jbl' in overall sound quality and construction. Does that mean you'll like them? Can't say. And yes, larger woofers will usually do better at dispersing sound. This can be both a gift and curse depending on the environment/placement.

It's shame that you can't really audition the speakers.
