1372.0. "Celestion Speaker Info" by SQUID::GOODWIN () Tue Jul 11 1989 15:04

	I'm trying to find out which Celestions Marshall uses in its
	4x12 cabs.  As far as I know Marshall offers two 4x12 cabs,
	one rated at 280 watts and the other at 400.  In the model
	1936 2x12 cab, they use Celestion G12T75 speakers, wired in
	parallel for an 8 ohm load. I'm also curious about Celestions
	model numbering scheme. 

	In the designation G12T75, 12 is obviously the size in inches,
	I assume 75 is the power handling capability in watts.  What
	does the G stand for?  Guitar?  And I have no idea about the
	T.

	There must be some hard core Marshall/Celestion fanatics out
	there who know all this trivia?!

    Yeah, you got it...G=guitar, 12=size of spkr, 75=spkr wattage capacity.
    
    Marshall had used 25, 30, and 35WT celestions in their earlier cabs,
    which are now sought out in droves my guitarists, as they realize much
    of the marshall sound came from the voice coils of the speakers being
    driven into overdrive!  Celestion offers a "Vintage 30" speaker, but
    its no more than their normal 75WT speaker with a differnt voicing put
    on it.  Rumor has it that Celestion will be re-introducing the ORIGINAL
    30WT speaker to their line in the near future, so be on the lookout!
     
    Celestion also offers 100WT and the 150WTx sidewinder speaker.  It was
    like their answer to the JBL line.  Its ok, but really too clean for
    rock guitarists tastes!!

    The Vintage 30 speaker is a 30 watt, and the vintage 70 is 70 watt.
    They come in 8 and 16 ohm. They sound different because the high
    end frequency response is reduced. You can't get the same speakers
    in the Marshalls , they're customised for Marshall by Celestion.

    I donno...I heard differntly from a guy who works for Celestion R&D.
    He said the Vintage 30 wasn't a 30WT speaker at all!  He said they
    would be coming out with the REAL 30wt speaker soon.  Again, he
    said the V30 was a re-voiced 70watter.

    ditto.  I also know someone who works for Celestion (hey Buck, maybe
    it's the same guy).
    
    According to him, the "Vintage 30" is really rated at 70 watts; it was
    intended to provide modern players with a speaker that would
    approximate the sound of the old "greenback" 30 watt Celestions, but
    with the ability to handle larger ammounts of power without getting
    fried.  Interestingly the voice coils of the Vintage 30's are actually
    much closer in construction to the VOX Bulldog speakers that appeared
    in old AC-30s.
    
    Celestion will be doing a re-issue greenback 30 watter that is rated
    at a true 30 watts.  In fact, I've held the first prototype in my hands,
    and they've certainly done a nice job of recreating the cosmetics
    of the old speakers (haven't actually heard it yet).  But my guess
    is that these will be of interest primarily to people who want to
    restore an old cabinet and/or have one of the old heads.  For practical
    gigging or use with modern amps, the 70 watt "Vintage 30" is probably
    still the best 12" of this type on the market.

1372.5Would wurlitzer's steer u wrong?VLNVAX::ALECLAIREFri Jul 14 1989 18:565
    What I said is just what Wurlitzer's told me when I bought 2 Vintage
    30's;  I could have ordered 70 watt or 30 watt, I ordered 30 watt;
    ditto impedence. It may have been made from parts of 70's, but the
    thing says 30 watts on the back. The magnet struck me as alot smaller
    than the 100W EV's I have, but they're shielded and huge.
1372.6Bigger is better! (ar ar)CSC32::G_HOUSEBe excellent to everyone!Fri Jul 14 1989 20:346
    re: .5
    
    The magnets on about every speaker I've ever seen look smaller then
    EVs.  EV uses some monsterous frame/magnets!

    Don't know how much help I'm going to be.  According to the Marshall
    book, the G12M25 and the G12H30 accounted for 80% of Celestion's sales
    in the 60's.  There's no specific mention of the G12L25 or any clue as
    to why they would be re-issuing this speaker.
    
    The letter suffix after the "G12" refers to magnet size; L = light,
    S = small, M = medium, H = heavy, T = medium (same as M, used on modern
    speakers).  So a G12L25 has a lighter magnet than a G12M25.  Since
    I haven't heard these particualar speakers I can't comment on tone but
    you might reasonably expect a G12L25 to overdrive easier and have less
    bass response.
