Seeing as how it seems Time Windows are getting harder and harder to come by and there potentially being a market for new speakers it seems that maybe this approach can also be of benefit.
I've read through about the first 320 posts of this thread and if someone has posted instructions like this I apologize for repeating what may have already happened.
I built and a set of TW7 clones (starting at post #784
), a custom center channel speaker (starting at post #213
) to match the set of TW7's that I already had, and converted two KX-Centers into SurroundScape Centers (starting at post #731
) with a TW7 tweeter, tweeter circuit and anti-diffraction lens . In the case with the TW7's, they were built as clones. They were the exact copy of the originals with the exception of the polypropylene over polyester film caps. The TW7 Center speaker was based off of the DCM CX17 but added the TW7 tweeter and accompanying tweeter circuit and anti-diffraction lens. The SurroundScape Centers conversion (starting at post 731) also added the TW7 tweeter and accompanying tweeter circuit and anti-diffraction lens. In all cases, they were DCM cabinet designs, using the correct DCM drivers with their matching crossovers. Everything was already well engineered by Steve Eberbach to work together. He did suggest (because I was building new) that I could use polypropylene over polyester with the film caps, the CX17 cabinet size can be increased by 10%, (it's original design size) and how to properly integrate the TW7 tweeter, tweeter circuit and anti-diffraction lens in the CX17 and SurroundScape Center design. Again, these are all things he designed and tested, I didn't mix and match anything.
So, to answer your question: "Has anyone tried to build a pair of speakers from scratch that sound like Time Windows?".
Yes, I have.
Now, if I understand you correctly, "Either by perhaps copying the crossover design and then selecting new drivers from Parts Express and then constructing cabinets that are like the original speakers or at similar in design?"
. No, I haven't.
Why? Because they wouldn't sound like what Steve Eberbach designed his TimeWindows or other DCM speakers to sound like. That's why I adhered so closely to what he did. I wanted to reproduce that sound. I'm also not saying that you can't do what you suggested, it just wouldn't be the same.
That's why we try to rebuild/preserve Steve's work here in this thread.
