Celestion thump

Love my tones these days through my RIC creambacks but I want to run a second cab not only to give them some rest, (NOT MUCH) the one tone I need to blend in is some low end thump.

What I don't want is to have the secondary speaker to overrun the mids and highs of the creamback.

First thought is the G12H-30 55hz or maybe the original Marshall branded V30. Who wins?
 
The issue might be the sensitivity (loudness) of those old CBs. They will likely have less output than most modern Celestions. They might get buried too much.

I have yet to find a G12H-55 that I like. Recently sold some BB versions of that. G12H-75 can be decent tho.
 
Old 70's straights. I'm not mixing cabs yet so nothing is getting buried yet. FourT6and2 brought his cab that had the creamback H75 and that's when I heard the low end thump.

I like my M25 creambacks detail and only need to add that low end thump. The question is what is the smartest way to not cover up what is already there.
 
i have the G12H-55 & they can be kinda bright. i'm actually looking to eventually get rid of at least 2 of mine.
 
I'd go g12t75's cause they are scooped and have good bass response. V30's would dominate because of the upper mids they have.
 
A redback has a pwr rating of 150w. I might run one in parallel with the 412 creamback cab?
 
G12 65 like the ones Metallica used on M.O. P. maybe? Either way keep the CB's up top. I can tell you G12T75'S might be a little too loud even on the bottom and have more highs. I've never tried Redbacks but they seem to be another possible solution.

Ok, I'd try the following:
- 1st: add another (same specs/speakers) cab for a full stack effect; you'll get "more" of what you already have, might be the ticket;
- if still not quite there, then I'd look into a 2nd cab with old original early/mid 70's G12H30s. I prefer the lead cones for what I play; still get that "old classic greenback" vibe with more "thump" as you say, stay tighter but still gets amazing old school feel, not too stiff nor high end harsh (like the newer Heritage can be to my fingers & ears). Bass cones will feel & sound "cleaner".
- 3rd option if feel is still not there: look into slightly later higher power late 70's / early 80's Celestion for that 2nd cab; could be G12-65, or even G12H-100 / G12K-85 (the later being even farther from the old 70's G12M Creambacks).

I was playing my HG Jose amp through my 75Hz and 55Hz Celestion Heritage 12H-30 speakers 4x12 cabinets the other day and the 55Hz definitely cabinet had more low end response than my 75Hz and was a bit darker but not muddy by any means compared to the 75Hz 4x12 cabinet. The cabinet with the 75Hz is a JCM900 1960B straight and the 55Hz cabinet is a 1978 1982B cabinet.

I haven't played any of the newer 12H creamback line. I am considering possibly some Scumback Blackback 55Hz 30 watters for another 1960A cabinet that currently has Mesa and UK V30's in it.

The only other suggestion I have is maybe the new UK V30 or Mesa spec V30 on the bottom and the 12H30 55HZ on the bottom and whatever other speaker you like on top like Friedman does with the V30 M25 mix he uses. I am also considering this myself.

It also depends on if you are a 12H-30 watt guy or a 25 watt greenback guy.

M65 or H75 Creamback? There's a significant jump in sensitivity between the two which could make a big difference in what you should pair them with.

If it's the M65 I would think either a G12-65 Reissue or T75 would pair well, and add a little lowend thump, and air to the treble.

If it's the H75, then the 55hz Heritage G12H will add some chewy low mid thickness, and depth to the lows, as well as some sweet clear treble. They do that glassy Hendrix breakup beautifully, and make for thick chunk on heavy fuzz and high gain tones. BUT, they are only 30 watts, so remember that when it comes to what type of wattage the speaker sees. In a pair your max wattage will be 60 watts, and in a quad 120 watts.

I currently have two Heritage 55hz G12H's that are paired with two Fane AXA12 alnicos. It's an awesome, warm, and fat in a vintage way sounding cab with insanely delicious midrange grind. It has punch, but there's also a gorgeous bloom to it, the highs are sweet and clear, never harsh. To my ears the AXA12 sounds like a warmer and thicker alnico Greenback, so not far removed from the M65 in its EQ, but it's significantly louder at 101 db vs the 97 db M65.

Ahhh, just read your sig. Yeah, I think the Heritage G12-65 or regular T75 would be your best bet.

If you don't have problem buying used, and are willing to search a bit, and pay a bit more there are vintage 55hz G12-65's out there. I have a quad of them in a JCM800 Bass Cab. They sound amazing, warm, fat, punchy, and sweet. One of those would probably pair really well with your 25 watt Creambacks.

The only way to increase the thump of your current setup without another speaker fighting or altering the in room frequency response of your original cabinet is to get a second identical cabinet. Two of those running together should thump harder than a single cabinet with moderately thumpier speakers.
 
I'm thinking the same atm. Maybe run the G12H100 in parallel in it's own cab/1x12

Totally solid logic and advice there. I think it's difficult to encompass all things in just one cabinet.

I remember those sub cabinets that I think ISP sold so a while.

There was a guy that used to post on here Submancometh......????? He had some chuggy shit on his channel...I can't find his channel now.

Maybe a used ISP sub will fill the lower end while keeping your 4x12 to what you like??
 
It might be but what I don't want is to fill a whole cab full of anything that will draw away from the core tone of the creamback G12M-25. This HAS to be done in a clever way. Not with an eq, not with a whole cab.
