Recommendations for replacement for G12T-75 speaker

Re: Recommendations for replacement for G12T-75 speaker

The Wizard is my favorite Eminence speaker, likely because it is the Emi with the most Celestion-like characteristics lol!

Although the general voicing is "based" off tne Celestion G12H30, it is 75w and has a tighter, stiffer lowend as a result. The speaker flat out screams...super loud...super crunchy. Lots of clarity and punch.

Mine too. They're shockingly close to the blackback G12H30s in my late 70s Marshall box. I'm also a fan of the Private Jack for cleaner and edge of breakup tones.

Re: Recommendations for replacement for G12T-75 speaker

I wanted to provide an update about my experience and impressions so far in sampling speaker candidates to replace some or all of the G12T-75s in my Marshall 4x12. I really appreciate the great insights and recommendations that members have provided in their replies to this thread.

Before I get to the speakers themselves, I want to mention a change in speaker configuration that I have made that I think I will keep as I move forward. Prior to this experiment, I had been running all 4 speakers in the cab. At this point, I prefer running just 2 at a time - either the 2 on the left side or 2 on the right side of the cab, with each side being a different set of speakers than the other. That gives me two voicing options to switch between, depending on what is appropriate for the genre I am playing at that moment and/or the characteristics of the guitar that i have plugged in that moment. Also, the tonal differences that occur just from running at 4 ohms load vs 8 ohms load probably has some impact too but it's hard (for me) to say how much.

So, speaker-wise, I tend to most often prefer the side that has the Celestion V-type mixed in, vs the side that has the 2 G12-65s. That is probably more due to me playing metal genre material more of the time than rock. That V-Type has more mids than either the T75 or the 12-65, but without the V30s nasty mid spike. The overall sound improved when i replaced the T75 that I was combining the V-Type with, with a Eminence "custom-design" that came out of a Jet City 1x12 can that I had sitting around in a box. This combo really resolved the loose low end issue i had with the T75. So much so that a Dean Icon guitar that I planned to sell off because it seems inherently boomy in its low end, now does not suffer that problem.

While i do think the G12-65s are an improvement over the T75s, it is the G12-65 side that i would like to explore further options , like swapping one of them with one of the recommended speakers that some of you have recommended, like the Classic Lead 80 or the Eminence Wizard. The G12-65s seem a little too "warm" and/ or "soft" for my tastes - not sure exactly how to describe it. I have been keeping an eye out for a used Classic Lead 80 on Fee-Bay, Reverb and other sites but most are priced so that they are not much savings over just buying new. I will keep looking though, as well as used Eminence Wizards.

Thanks again everyone.
 
Re: Recommendations for replacement for G12T-75 speaker

I run a Marshall 1960A 4x12 cabinet, currently loaded with 4 Celestion G12T-75s.

The problem I have with the G12T-75s is that the low end can get too boomy. [EDIT: boomy not just on the distortion channel of the amp, but even on the clean channel]. So I'd like something that is tighter in the lows. I play metal, so the replacement speaker also has to respond well to me scooping the mids via the amp's EQ controls.

I had previously A/Bed at the same time, one 4x12 with G12T-75s against another 4x12 with Vintage 30s, and i did not like the Vintage 30's famous mid spike, so the Vintage 30 is not a candidate in my mind.

Thanks

If no one has mentioned it yet, how is your 412 wired? Series/ Parallel or Parallel? Big different in feel between the 2. Speakers wired in Parallel, for a tube amp, will increase the Damping factor in the head. This will allow more accurate control of the low end. I suggest, if you have 16 ohm G12-75T's that you rewire the cab to a 4 ohm load. My 412 of G12-75T's are wired that way and I have no issue with tight low-end.

If that is not tight enough, then step up to a 50oz Celestion speaker. the G12H Creamback or Greenback, maybe the ticket for you. Even the Classic Lead, should be less harsh than the V30.

Hi, thanks for the input

I run a solid state head, not tube.

My Marshall 4x12 is a 1960A model that has the ohm choice options switch on the back. I had originally been running my 4 T75 16 ohm speakers at 4 ohms, as you suggested. The cab also gives the option to run the left side pair at 8 ohms and/or the right side pair at 8 ohms.

See my latest post from earlier this morning. I have gotten a lot of improvement already by trying a couple different speakers.

okay cool. I'm glad you are on your way. Solid State will probably benefit from Parallel wiring as well, but you already had that so I'll be quiet.
 
Re: Recommendations for replacement for G12T-75 speaker

I'm a big fan of the gt12-75 but admittedly it has a TON of bass(love it for cleans and bluesy... but sux for metul!) but for me the part I'm not a big fan of is the increased high range response (again great for cleans).

I have a full stack with mixed gt12-75t, v30, and greenbacks. I've spent a lot of time standing in front of my stack and positioning my head in front of each speaker and comparing. now I am deaf... so my opinion probably is wrong.

I also have two 2x12s loaded with one gt1275 and a greenback each. After setting up those two cabs I noticed a huge difference in the (less)bass response between the 4x12 vs the two 2x12s. At first I assumed it was the dif between a solid wood 2x12 cab and a marshal 4x12. Then one day I was playing around with the 2x12s and their placement... and all of the sudden the bass was back and overpowering. Those two cabs are normally on cab stands sitting a hair off the floor. When I put them back on the floor the difference was so obvious it was hard to believe. I subsequently put my wheels back on my marshal 4x12 and sure enough... bass was much more tame.

long story long... it's not going to change a gt12 into something else... but it might be an aspect you can consider with those or any other speaker(s) you go with.

ps, I really like the mixed 4x12 cabs. standing 5' back it sounds great and with a close mic I can get all sorts of variation by moving in front of dif speakers.

hope some part of my thoughts was helpful!

Thanks, the idea to check the difference in bass response btw on floor or off floor is a good one. In my case, my cab is already off floor: its on wheels.

I too see value in having different models of speaker available to choose from for mic'ing purposes.

Your view of the G12T-75 is so different from mine. I hear that speaker as a dated 80's Metal sound. I don't really love it clean. It's cool for some scooped high gain stuff. The cleanest and most balanced Celestion I have is the dreaded G12m-70. I've been toying with mixing that with something else, but not with a G12T. I tried that and it was NG. So what does the Greenback bring to the table mixed with the G12T? Does it fill in the mid? Add extra grind? Is it a M or H greenback you are using?
 
Re: Recommendations for replacement for G12T-75 speaker

Just wanted to provide another update, and hopefully it is of use to anyone else going down the same " what replacement speaker" path.

I already mentioned that i have been liking the tones i am getting from running a Celestion V Type paired with a Eminence budget version of their Legend speaker (i.e. the JCA-12-1716 speaker that comes as the stock speaker in a Jet City JSA 12S 1x12 cab). That combo is good for the Les Paul types of guitars i predominantly play. But it was a little shrill when i plugged in my Strat for occasional usage. I also found the sound to be too shrill when alternately running the Strat into a pair of Celestion G12-65s. Well, last night, i had the idea to see if a combo of one G12-65 and one Eminence JCA-12-1716 might resolve the shrillness issue when using the strat. My ears told me, yes. This evening when i came home from work i tried it again just to be sure. Yep, that pair is a winner. So while it may be unglamourous, that Eminence budget speaker is doing a great job in now 2 applications as a flat/neutral speaker to mix with another "color" speaker. My .02.
 
Re: Recommendations for replacement for G12T-75 speaker

I’m very much a fan of running complimentary speakers together too.
Sometimes each speaker contributes what the other can’t and vise versa.
