This is turning into a really interesting brain-storming idea thread.
What led me down this path was that I made an impulse buy of a brand new pair of CSS-Audio LD25X tweeters. The first 40 pairs were available at a nice discount to get, so I jumped on a pair without much thought on what I wanted in a pair of speakers. Once they were in my hot little hands, I began thinking about what kind of speakers I wanted. I quickly decided that I wanted a nice midrange driver and an 8" to 10" woofer. For cabinets, I'm pretty certain I want stand-mounted speakers - perhaps 24 to 26" tall by 9" to 12" wide. Depth - thanks to my TV cabinet's depth - could be as much as 22".
Before Nick began this thread about Carreras, I had already tentatively tightened my midrange driver choices to a Satori mid, a Revelator mid, and an AT mid. I'm still fishing for a woofer.
Now, I've never heard the LD25X tweeter. I've heard its little brother - the 22mm driver, but I haven't compared its sound to other tweeters. I don't know how committed I am to using the LD25X for this idea. I know for a fact that I like the tweeter in the Fritz LS/5-R speakers. It's the same one that Fritz uses in his Rev 7 SE speakers. This led me to wonder if I could get Fritz (or another speaker designer) to modify a pair of Carreras or Rev 7 SEs by adding a big woofer to make a three-way. [I know. Call Fritz to chat with him. I eventually will, but not from 5000 miles away.]
That's all for the moment. My wife and I are departing ATL for Taiwan in a few hours (with a 6-hour wait in SeaTac) for our connecting flight to Taiwan. I don't have adequate time to fully explain my thinking right now, so I'll try to follow up later - perhaps while we're languishing at SeaTac.
