Where is a good place to get specs or other info. on older speaker models? I've tried eCoustics, audioreview, and a general yahoo search with no luck. Are there other sites to look at? I'm looking for info on 12 year old speakers for example. Also, what do people think about older speakers versus newer speakers. Has the technology really made a great difference? I've heard some people say that the older speakers were better or at least better constucted. Any thoughts?
