    Looking for the closest sounding current Celestion to a 70s Celestion G12H Blackback 55 hz but in 100 db sensitivity instead of 96 db. But I think I want to try a 75hz this time around. Going to pair it with a pair of Cream Alnicos in a 412, close back of course. I guess that would be a G12H-30 Anniversary but not sure . Thanks in advance.

    I had a 77 slant with 55hz 30 watt Blackbacks the same time I had a 2061cx with Anniversary H30's and they were NOTHING alike. Now obviously the cab differences play a part and the Blackbacks are 40 year old speakers while I only put about 20 hours on the Anniversaries, but the difference was drastic.

    The Anniversaries sounded like crap BTW.

    I have no idea what the 70s G12H Blackback sounds like. Pretty niche speaker you are after by the sounds of it.

    Current production Celestions, 55Hz, 100 dB (and you can get all this from their website):

    Heritage Series G12H(55)
    Neo 250 Copperback

    That is it!

    I have recreated the 70's BlackBack tones with the BH55 (55hz G12H30), the BH75 (75hz) and the BM 55/75 for the G12M models.

    A pair of Classic Leads might work for you.

    CL80's are a large dust cap speaker while the BlackBacks used small dust caps. But they may work fine for the OP.

    since 75 Hz will guarantee it WONT sound anything like a 70s G12h-55 blackback, just get whatever speaker you want and buy a black magnet cover on eBay to put over it.

    Are 70's Blackbacks really 96db ?? My 77 Blackback 55hz H30's are noticably louder than my 68 Greenbacks. I thought H30's were 100db, or is that just modern ones ??

    good to know. I had a '78 straight cab with blackbacks and I loved that cabinet. I want to get a vertical 2x12 like the SV212 but jeez, 800 bucks and I'd still want to have black back sounding speakers in it.

    Not in my experience. The BB with Mueller cones were usually a hair louder than the Pulsonic cones from the 60's. M's were 97db, H's were 100db. But the rating is conservative on the BB's. I've compared my BB's to the Pulsonics and they seem to be a good 5% louder with the same amp settings. I've got a 4 way cab switcher so it was easy to click over instantly and compare them side by side.

    ok i'm still a beginner ,but when i played guitar as a kid in the 80's i had a marshall 4x12 1960 cab ,it was probably a 1976 and it probably had black backs in it , i recently paired 2 greenbacks (a reissue and a evh ,)with 2 jbl d120f's and the greenbacks sound pretty close to what i remember .
