How would you have put it?
There are certainly things about people I don't have the ability to understand. Most can't be discussed here.

That was me. Can never have too many woofers.

So I finally had the time to go over my latest acquisition carefully. One tweeter was a Peerless copy, had the i” tweeters both sides and all wrong fuses.
I obtained correct 3/4” tweeters many years ago so sent those off to Richard. Had a spare pair of mids so sent them off as well. Obtained correct .68uf caps for the smaller tweeters and yesterday and today replaced all the drivers, the tweeter caps and the Mallory 90uf woofer caps with Mundorf 100uf caps. Sounds Damn nice. Tomorrow I set up the biamp system. I’ve decided to go with vertical bi-amping. I have three different xovers to decide which sounds better. Dbx, SAE 4000, Behringer. I’m usually disappointed by the Behringer equipment sound. It will most likely be the Dbx since it’s newer and easier to set up. If the 4000 is up to spec however......
So now I have two well working mids and one 1” well working tweeter that’s available which I thought I would give you all first grabs before putting them up on flebay.

To Allhartfidelity,
Sometime in the past someone actually replaced the board mounted socket and cable mounted plugs with your molex recommended flat blade connector. Must have been done when the board mount sockets where still available. So I now have a set of new cable mount Molex connectors male and female available.

I’ll post a couple pics soon.
I have another issue that needs the collective’s thoughts.
I very carefully wired the speakers for biamping. Correct plugin card, moved ground plate over etc etc.
What I got on power on the system was a ear splitting screech from both speakers.
wtf did I not do correctly?
Any thoughts?

Great thread here! Some local 910 with stands in excellent shape sn5885 for $1000. Seriously thinking about them. My other speakers are Spendor SP 1/2e, Altec Valencia and Bozak Symphonys. These seem like a nice add. Always lusted after them back in my 70s hifi store lurking days. What should I look out for when I check them out?
I personally look for signs of drivers having been removed. As may be evident from pry marks around the outside edges, or clearly some drivers having Philips screws toward the center (holding the plate to the magnet) and some may have hex screws. Looking for discrepencies between drivers. Some folks replace drivers with incorrect. While not a deal killler, can be an added cost to set right.
While there are other issues such as solder joints on xover to adress, this is not something not to worry about before purchase as most all need it touched up any way as matter of practice. Some folks prefer the older woofers some prefer newer (evidenced by size of the dust cap) some folks prefer the ibeam construction stands some prefer the flat, and always look for the led cards in the xovers of course.
When testing i do reach into the back hole and give the umbilical a slight wiggle while leaning down front with an ear to listen for driver dropout in the mid/tweet ect.
Ive had 10 pair or so, most all have umbilical issues due to solder, AND/or loose connector. Ive modified mine personally (and many others) to eliminate the issue resulting in better performance but i am in the minority on that mod. Having been inside as many as i have, its something i like to do for longevity and performance.
In short, cosmetics like have they been refinished (i dont like them having been done because its usually done poorly) and have the drivers been monkeyed with. Listen to each driver individually for function, and make sure you can get adequate power to them for testing at a decent volume level. (As with any speaker)
A great speaker and worthy of these efforts up front, as further reasearc after the fact may reveal some of the things mentioned thus spoiling the moment some. Good of you to ask in advance.
When buying any gear, i also look around the house of the indicidual and size them up...if they have a bunch of disorganized crap laying about AND its clear the drivers have been out, then chances are its disorganized INSIDE the speaker as well. Its hard telling whats been done to them over the years, but not impossible to surmise based on small clues.

Wow, i missed this post. Nice to see someone else does that, or mabe one of my sets made it to you? Prob too small a world for that?
My work is rather particular, having used new pigtails on the board itself. I bend the wire over and solder directly to the trace, leaving 8 or so inches off the board.
The molex ore still avail, but i have not seen any with the pigtails attached in a while. I do still have one set left, figure another pair of 910 will cross my path again one day. I also have boamp cards and led boards at the ready when (not if) they happen to come within reach.
The sae would have been my choice, as it it is recommended by ADS.
If its the set where the guy ends his add by saying "Don't settle for the smaller ADS" You'd not have even had the chance to post in here if I lived closer to that guy. They look really nice in the pics. Drivers look original and clear/clean.

A pair is out there, destined to be in your house! Keep searching!
I picked up the set of 910s yesterday and they are in great unmolested condition. Going to hit the cabinets with some Howard’s and get them back on the stands and in place later this week. $800 including stands and covers was a very fair price considering the condition. Unfortunately, a little blanket fuzz got on one of the mid ranges in transport, so I’m going to get a pair of plastic tweezers later and pick it off....very carefully!
Shoot some Pics maatchka we'll ALL appreciate them. Good on you finding them!!

You're going to love them! Feed them lots of power, and your neighbors will be rewarded!
May I suggest before applying the Howard's, you give them a good wipe down with some diluted Simple Green or similar.
Bummer about the fuzz, and yeah be careful removing it.
Do yours have veneer, or painted black on the backs of the cabs?
And yeah, post pics!
Cheers, Glenn
