    Hi all,

    I am needing to replace the speakers in my Twin Reverb SF. I am looking at the Celestion G12V70 (which I believe are in the current reissues). Despite all the comments and videos i've watched I still can't get my head around the Wattage and Ohm information.
    My TR has 100w output and 4ohms wired in Parallel & the 2x Celestions are 70w 8ohms each.

    Will these work fine with the TR?

    The Celestions should work fine. If you come across a pair of JBL E120-8 speakers, give them a serious consideration as well. There are some that disliked those speakers so they might be available fairly cheap, but they happen to be a favorite of mine in a '79 Twin Reverb that I have modded to Blackface specs.

    Yes. If you wire two 8ohm speakers in parallel (as per the standard wiring connector) you have 4 ohms. Do not buy 4 ohm or 16 ohm speakers.

    A pair of 70 watt speakers will handle 140 watts - in series, parallel the power is split between them. Fenders will handle (mostly) a 100% mismatch but best is to match the spec.

    I recently put a pair of vintage Altec 417-8H speakers in my '71 Fender Twin. I've never heard a Twin sound so good. For me, this is the perfect Twin/speaker match. I highly recommend these if you can get your hands on some.

    The Celestions will certainly work for your TR. In general, any two 8ohm speakers wired in parallel with sufficient power handling should work for a twin reverb. I would generally want speakers rated for at least 50 watts for a blackface Twin and 60-80 watts for a silverface. "Correct" is largely a matter of taste and is quite subjective. Personally, I prefer alnico speakers like the JBL 120s or the Altec 417s which is what I have in mine. I've seen a lot of positive comments for the Weber 150s as well.

    Yeah 150 watts total on the speakers should be good. All else is your choice really. I'm not familiar with those particular Celestions.
    Emi Legend or R, W & B's, or Weber Silver Bell 75 watt, or maybe 12F150's 75 watt would be on my list to consider for a Twin or Pro for that matter.

    I think there are a lot of great speakers for a Twin, including the ones named so far. I've liked what I've heard from some Celestions in Twins of all stripes, from tweed to BF/SF. Most recently, I played through a pair of G12-65's in a BF Twin Reverb, and I also really like what I've heard of the sound of the JB-85's that come in the Joe Bonamassa HPTT.

    The Weber California model is a pretty good replacement for the JBL sound. But compared to actual JBLs they’re a little thinner.

    I just sent a pair of 1963 Oxford 12M6 to Weber for reconing, can’t wait to hear them!

    I run a pair of JBL K-120's with my '69 Dual Showman Reverb. I love that sound. If only I could still lift them!

    I like your style...I have a pair of 417-8C speakers in my 2x12 cab. Wonderful tone....but very heavy

    What speakers are in there now? Eminence? And what year TR? I think a lot of folks mistakenly replace the blue labels, and impair their Twin, rather than improving it.

    Those are lightweight speakers for a TR, ime. The TR would have used 12T6’s.

    Ah well, they supposedly came from a Twin but I believe you. I expect them to be much quieter than the D120fs, but I don’t want to blow em!

    12M6 would be a lower capability speaker.....30 watts is my WAG. fender was having problems keeping even the 12T6’s in TR amps. In 1966, the 12” speakers got wider voice coil gaps which reduced their efficiency while reducing heat build up...and thereby reduced speaker failures. Those low efficiency 12T6’s are good speaker in a TR IF a person wants to be able to push the amp a bit.....they will reduce volume by half at least, ime, compared to say a 100db speaker.
    If those 12M6’s are date code matched to that amp, that would be interesting, though.

    I myself would load er up with 2 x 90w Celestion Creams/Alnico. Killer speakers for a TRVB. I use 2 of them with a Blackfaced/ODS 69 Dual Showman Rvb.

    I also have 2 Hemp coned JBL E120s, 2 Altec 418H, Altec 421A and 2 150w Celestion G12H Redbacks. ALL of them sound great. The Redacks also are great, and can take 300w.
    100w Scumback H55 are also killer.
    For my preference 140w worth of speakers for a 100w RMS is not enough, and im compromising using 180w worth of speakers suggesting the 90w Alnico Celestions, but Ive had them 3 years, and have cranked them many many times, for hours on end.

    I also use them with a Metropoulos JTM45 clone.

    The a correct speaker for a Twin Reverb is the one that sounds good to you.
    One of mine has Radio Shack Utahs and the other some Celestions I had laying around when I got sick of the JBL D131s.
    I like the Radio Shack ones better. :)
