I was thinking about using two JBL E30's wired in series for the center channel. The brand isn't important, I'm just wondering if anyone else has done this and what they thought of it. Since these speakers are 8ohms connecting them in series should give a 16ohm load, right? Will this be easier for the receiver to handle than an 8ohm load? I was considering an EC35 center but I can get a pair of E30's for cheaper. I have no experience with type of setup so I would appreciate any feedback on the pros and cons for using 2 bookshelves for a center. Thanks.
