I bought a house from someone who had installed a 5.1 HTS. When he left, he took everything but the center channel speaker, which is buried inside some crown molding. It has an immovable grill in front. Unfortunately, I cannot tell exactly what type of speaker is in there and would need to rip apart the crown molding to tell for sure. The previous owner is lost in the mists of history. The store that did the original installation has lost all of their records on the speakers that they installed. I tracked down one former employee who did some installations around the time the HTS was installed. He thinks that the center channel is a JBL Control speaker. He recommended installing JBL Control 28 bookshelfs up front and Control 26 C/CT in-ceilings in the rear. I've looked at JBL's website and talked to a JBL representative. These speakers were not designed for HTS, and the representative did not think that they would work well at all in this setting. (Not sure why the original owner--who spent a small fortune on his HTS--used them in the first place, but that's a different story.) I'm now trying to figure out my options: 1. Tear up the crown molding to confirm what the center channel speaker actually is. If it is a JBL Control, then switch it out for a different speaker. If it is something else, then try to put it back into place and buy matching speakers. I'm not really excited about this because of the cost/delays involved. 2. Just assume that there is a JBL Control speaker in the middle, bite the bullet, and get the recommended Control speakers. I'm not excited about this for the reasons explained above. 3. Assume there is a JBL Control speaker in the middle, try to guess what it is, and then buy another brand that will hopefully be timbre-matched, etc. This seems difficult to do, though. 4. Ignore the center channel speaker altogether, get four other speakers that I like, and see if they go well with the center channel. If, as I suspect, they don't match well, then tear out the center channel unit and install one that will match what I have purchased. 5. Shoot myself in my soft, gently-rounded belly out of frustration. (I've been trying to get to the bottom of the speaker issue for three months now, and have made zero progress.) What do people think? If there is a vast, teeming universe of JBL Control fans who have discovered that these make terrific HTS, I'd love to hear that too.
