ID Rola G12 (Celestion Alnico)

That elusive piece of the overall equation, so many options and so little time to test them all — Celestion, Fane, Eminence, Jensen, JbL, Utah, Ceramic, Alnico, 1x12, 2x12, 4x12, 2x10, 4x10, 1x15, 2x15, 4x15, 1x18 and I'm sure there are even more!

The older speaker is definitely stamped B024 like the other one.
I had to glue down a short segment of lifting spider last night but it stuck down well without moving (i.e. likely to induce rub). I brushed all the way round the edge with rubber contact too as prophylaxis.
I put them in the 18w combo and they do sound very good with excellent definition and crispness that breaks up smoothly when pushed, i.e. when you dig in hard. All in all an excellent match assuming that they hold together 8)

Well so long as they sound good is what matters. Not sure about that 002 cone, its a bit of a wierd one.

8) They do sound very good in an 18w 2x12. But I may actually convert mine to use a pair of very early '66 T1220s that I am receiving today. No doping, so they are extremely early greenbacks with Jan '66 date codes. Will also be refurbishing a 1966 4x12 and may end up putting the 16 ohm alnicos in that one instead. We'll see... :jam:

I took my T1220s out and they are sitting on the side, ready for another closed back cab. I have had the alnicos for a while bu the 18w did sound great with the T1220s I was loathe to mess, but we played a festival on Friday evening (quick load in, 30min set and quick load out so I took the 18w to mic it up. It did not have enough clean headroom for the relatively high stage volumes we had (usually volume on 2.5 with trem channel - great for small intimate gigs). The alnicos are more sensitive and give a little more headroom with the sparkle I want. For venues that big I would ue 1/2 stack and probably will again in the future! 30 mins is not long enough to get rapport with sound guys to get side fills and wedge foldback sorted (it is usually the vocalists I prefer that they concentrate on).

Looks like the Rola labels were still being used until at least Sept 1959. Just spotted this one:

Something else I noticed is the very early ones (early 1950's) have "British Rola Ltd" text on the labels. The later ones (mid 50's onwards) do not.

or perhaps Im just more of a geek than most normal people. :lol:

also notice how the "reg trade mark" text is curved on the later label so that it fits nicely around the Celestion logo when its on there.

The speakers would have been made at the same factory (Thames Ditton after 1948) but they must have been pigeon holed as being either a British Rola, Celestion, or Truvox product, hence the different labels.
