Thank you for your comments.
Plans for these speakers are tentative. I had not planned to act (work) on these cabinets or open the units up for examining components (ohm testing, etc) until receiving adequate information from participants in the AR Classic Speaker forum. Ultimately, I want to connect these to my audio power units (MAC 240 and McIntosh MX110) to determine if these may remain in my speaker collection.
Previous to moving to Connecticut, I had a large property in the Monterey Bay area of California. I had a collection of numerous speakers (older AR's, JBL L series, and individual JBL and Altec speakers/transducers). Anyway, the entire lot shared space in my farm shed and in the walk in attic storage room of our house. However, with so many projects on board and having my McIntosh system disconnected, i spent little to no time interacting with this collection. As we sold the property, almost all of the audio equipment was sold (AR's, JBL raw speakers, Dynoaco amps, receivers), and I brought only 2 JBL pairs (L-100 and L-166), MAC units, a vintage Pioneer receiver (SX 950), CD player (Sony CDP-707 esD), turntable/tonearm (Thorens TD 124/Shure SME 3009) out to CT. The latter have not been hooked up as work needs to be done on the tonearm wiring. So, in arriving here, I got the "LetGo" bug as we started to refurnish our home. In doing that, a number of audio units have crossed paths (once read a woman's posting of "Four older big wooden speakers from parents house for sale/AR 3a"...she wanted $50 total...but I hedged!!!), but now have a couple of JBL L series pair of speakers for rehab plus a pair of Dynaco A-25's found at Habitat for Humanity Restore for $20. Lastly, my friend (who I was with when the AR-1's were located two days ago) has given me his L-56 pair of which one is speaker-less and the other with high and low frequency units. Once those units are removed, the speaker boxes will be used for an active crossover 3-way speaker system....another "thing to do".
As you can see, a number of "projects" are back in place, thoughts of what to do with the AR-1's just has added to it all. Most likely, I will test the speakers out (hook up an play), then try to think where and who would make the pair a good home. For sure, I do not want to affect the vintage integrity of these "classics" by breaking factory seal on back or disturbing the grill cloth. Paper labels on back are in fair condition (age darkened and stained, crinkles with cracks from humidity, but entire). However, concern about the AR potentiometers may prompt servicing these on one or both AR-1's. But, since this is an exhaustive process, it may be best to defer this to a "new owner" if the AR-1's are to be sold, and simply disclose operable quality of the potentiometers (scratchy sounding, clean, or inoperable) once the AR-1's are hooked up for testing on an audio source .
I will post photos of these units with special attention to the "white" finish, particularly any white that appears on the grill cloth. My thought is that the previous owner (original owner) purchased these as the "unfinished option" and proceeded to apply a finish for completing the units. In looking at the "finish", it appears that a second coat (or other coat) of "off-white" was applied over the "Pure White finish. This "Pure White" may have been the "Birch" option...but not sure about that option. If it were an "unfinished option" , this would seem logical since so many audio items were offered to individuals during the late 50's and 60's as "kit" or DIYS options (Dynakit, Heathkit, other). Serial numbers for the units are: 15062 and 14304. Before I take photos, perhaps folks may want to provide input to that photos are taken of specific aspects of these speakers.
Looking forward to folks input!
Best,
Geoff
