Thanks for all the responses to my original posting above. I've done some serious investigating on my own since the posting and found the following (from an ultra reliable source):
1. Each driver used in a Dunlavy speaker is individually tested to meet strict performance criteria. Individual drivers are matched in pairs for each speaker, and matched in fours for each speaker pair.
3. Individual crossovers are partially assembled for testing and then matched with a speaker for final testing. Crossover components are then individually adjusted (based on measurements of the speaker in an anechoic chamber) by a technician until the desired performance criteria are met.
5. Speakers are built and tested in pairs; each pair is matched within very narrow limits.
What does all this mean? It means each pair of speakers leaves Dunlavy perfect but physically and schematically different from each other. Plugging in a new driver direct from a outside supplier is going to undo everything Dunlavy worked so hard to accomplish. Is this worth 50% off to me? Can't make up my mind, but will shortly as I was about to purchase Vandersteen 2CE Sigs with VSM surrounds.
PS- I have the highest regard for Audio Video Logic. They provide us "nuts" with some very fine equipment at tremendous savings. Just think this is not one of those times. Thanks again guys!
