Hi ,
I just traded for an older Altec 15" speaker it looks like it has the bakelite spider . Would this be a 603 or 416 ?

Would be more valuable to restore with the original spider and voice coil or as a modern speaker a GPA would say .
:thankU:
Looks much more like a 515 series. 803, & 416 and others have a rear cover held on with two small machine screws through the back, or label side. If you weigh it and its over 25 lbs, the conclusion is indicated even more.
Hollywood production which would limit it to a 515 or 515B no?
The phenolic spider is just barely visible.
I believe GPA will reuse the original spider.
pretty much in concurrence, an old 515, my guess is just 515 not B.
I think GPA can recone and either salvage the original spider or replace it. Check with them IMHO it would be worth more repaired and working.
Sorry to go a little off topic here but it reminds me of a similar question I have been wanting to ask.
My 416's read "416-8". Does this mean they are 416-8A's or what?
Sorry for getting loose here...
Send it to me, and I'll test it over the next few years, and then I'll let you know :lol:Quote:

Battradio, it looks like a circa 1945 or 1946 model 515 from one of the early Voice of the Theatre systems. It will be worth more to a collector if you can retain the phenolic spider and original style cone. These drivers are sometimes called 515A, though AFAIK Altec never gave them that designation.
Now about that 1400 series RCA woofer the 515 is sitting on... yum!
Early Hollywoood 515 RWB I think Steve hit the nail on the head on date.Try to keep all original but obviously needs to be reconed do you have a reading across the terminals.

Altec badged instead of IPC, but definitely 515's, the original paper surround.
GPA can only make 515B's out of them, but every once in awhile an original 515 recone kit will surface on E-bay for usually a pretty penny. However, there's no way to guarantee the condition or quality of the materials at this point...
BTW, you've really been bitten by the old Altec bug, huh?
Did I mention I have an extra VIT?!?!!???....:D
Its in the Mail Right now , The voice coil is good and will have it it restored with the oringinal type cone using the existing voice coil and spider .Quote:

Hi AB,
As I remember there IS a serial number on the back side of the cone. Right now they are in my Valencias (846B). I don't remember the numbers though. I was just curious because there was no letter after the 416 8 stamped in the rear of the driver. They are from 1975 so I presume they are pretty early in the 416 series. I'm kind of new at this. I'm learning every day. I love this forum. It has brought me back to a place I have missed for many years. Most of the time the discussions are WAY over my head, but as I said I'm learning.
As I said earlier, my Val's are completely original. I was thinking of upgrading the 806 drivers to 902's. Also changing the XO's. Any suggestions on the XO's?
Thanks...

Although I believe a few might have been made later but not many.
Thanks OG,
It would appear I can replace the 806's in my Vals with the 902's and keep the N800 XO's. This seem a good mod. Too bad my 416A's aren't B's. Oh well...

416-8B was available in late fall of '74. Late model 846B/U's could have left the factory with either woofer, i've seen them both ways and it's not unusual to encounter pairs with mismatched woofers from that late vintage.
Worked out a trade for the RCA speaker :2thumbsup: ,what should the field coil impeadance read in ohms ,from what i could learn it takes about 115 volts DC for the field coil .Quote:

Saved it fro being used as a guitar speaker .
Nice score on the RCA!
The RCA's voice coil DCR should measure around 16 to 18 ohms. The rated impedance is 30 ohms, though a later RCA service bulletin said that the impedance should really be considered 60 ohms when making crossover connections. In the old days RCA often ran high and low frequency lines at 250 ohms from passive crossovers in the booth and transformed the impedances at the speakers using multi-tap autoformers.
That woofer voice coil is a four layer job wound from very fine wire, and they can be a bit delicate. A friend lost a 1444 voice coil when lightning struck near his home.
RCA Maufacturing Co. boy that is an oldie especially since it was made in Camden,N.J.
