Neat, huh?
It's what I do. :yes:
[I'm still trying to figure this one out....]
KLH 17 tweeter is not on the centerline, and thus they are not mirror-imaged, and imaging suffers. It was not an issue when these were designed; max dispersion and soundstage were the priority.
Certainly not until I get a crossover working here. I do like both of these HF drivers and waveguide combinations, but if your 23s are deeper than the 17s, the 8" square EconoWave may be a better option, since it uses a PT waveguide. How deep are the 23s inside?
"Hacking?"
I have some alternative Daytons coming this week. In the meantime, I'll try to figure a way of sending 17 woofs back and forth, maybe USPS fixed rate.
The 8" square PT waveguide measures 7.875" from the rear of the flange (front of baffle) to the back of an installed Selenium D220Ti.
THAT, fellow AKer, is yet to be determined. They were headed for the landfill because they sounded like poop. They measured like poop, too. I'm giving them the benefit of the doubt in suggesting that the stock woofers that were in these are damaged or defective, and seeking means of making a more definitive determination.
It's DC250-8 I'm trying next, acquired, actually, for a different project.
I sometimes do, but haven't here. It's a crap shoot guestimating. Even when I try to measure that, I seem to get it wrong.
Seems there's good reason the early two-way AS designers struggled with getting tweeters to play low enough to match up with low Fs, high Qts woofers....

As to the Mona Lisa analogy, specifically, we've been over that in thread after thread after thread here. I don't listen to any of it with respect to describing a loudspeaker. You're talking about YOU, not the speaker, or how it might actually perform, which is another matter entirely.
I fully understand and appreciate that there are many members who like and enjoy these and similar thrift store "finds," and pursue their restoration with considerable satisfaction. That is NOT, however, the only rational course....
