Ok boss, here's what I have
Doesn't sound too bad
I like speakers with potentiometers
Don't know what the cross-over frequencies are
Sound pretty good, maybe I can just add a notch filter for the mid-dome?
Haven't hooked up the woofers yet

Maybe I should get XT25 and copy Falcon cross-over:
Peerless 830869 and RS52AN @ AmpsLab

Kind of a waste to get a mid-dome and not go with ribbon tweeter, but I love the XT25
You can hear so much silliness with a ribbon and a XT25 for that matter, but seemingly not as much as a ribbon

Those enclosures appear to be in gorgeous condition. Why not just tune up the original Yammy crossovers, rub in some Howard’s Orange Oil finish, and enjoy them while designing your all new 3Ways?
And don’t be surprised if the 670s are musical enough to want to keep unmodified.

Hard to find a better brand of older speakers than ADS.

I agree with you 100%. Stock is far better than any botch job he is attempting to do.

And I find it funny that throughout the entire thread, he has completely ignored every single post I've made here. Apparently, he has no valid response.

It would be like someone buying a brand new C7 Corvette ZR1, getting it home, yanking out the 755 hp supercharged 6.2L motor and throwing in the base Stingray's naturally aspirated 460 hp 6.2L motor. Why? What's the point? It's not improving anything.

Meh... Whatever.

When you argue with a fool, you become a fool

Who me?
or chops?
or both?
I tend to get cheeky too
I think it's all in good fun, well for me it is

Chops is kind of right, but I'm not into vintage drivers
A lot of things age in 40 years, even far less
Materials aging; therefore suspension compliance changing is the biggest problem
But there are many others

Very very nicely built speakers though, drivers, woodwork grills
I just want to reuse the cabinets because you can't buy wood this nice locally

But it seems to be a lot of work; well a lot of thinking, then a lot of work probably

I just want to slap something together quickly
With the ADS I could be done in a day and then take my time changing the cross-over

Jimmy - how much time have you actually spent listening to either the Yammys or the ADS in their "stock" condition?

While admittedly only passingly familiar with only some of the smaller ADS, I did own a pair of the 670s - among dozens of others "back in the day" - and quite liked their performance, and compared to many similarly priced US brands of the era, their build quality was vastly superior.

Just slapping something together, and then fudging around with the cross-over later is certainly an interesting approach.
