I recently moved into a new house and in one of the rooms there was a radio shack in wall speaker. So I popped it out and there was a little woofer. I think it was a 6" or something. But the tweeter was different looking. After doing some research I found it was a lineaum tweeter. It pretty neat and I read some mixed reviews on it. It's model is et-5a. I was thinking of making it the tweeter for a center channel. What do you guys think? I haven't gave it a listen yet because I have nothing to put it in.
