"I think I have narrowed down my choices to the ELAC Debut B6 and Wharfedale Diamond 10.1. Both are roughly $259 shipped and can be returned easily. Sensitivity is 86/87db for both."
Keep in mind that because both are 6 ohm speakers, that sensitivity rating is for 1.5 watts. Correcting to a 1 watt rating will be 84.5/85.5.
