Hi all,

I have a 2x12 speaker cab equipped with 1 x Celestion Greenback and 1 Celestion GH12-30.
The cab is brand new, and so are the speakers. When running the cab, especially on low volymes, the bass/low end is a bit to much, and i find my self setting my amps treb to almost max.
At rehersal there are still alot of low end from the cab, but since playing much louder it doesent bother me as much.

The back is made of 3 pieces making it fairly easy to convert it to an open back. I have not tried this yet but that is one thing I have to test. Allthough I fear that the greenback might not sound as good with the open back config.

So are there any other ways that you can reduce the low end in a cab, fill it with something maybe?

Thanks in advance!

Nope, that I have not tried. Will give that a shot.

Just looking at damping materials and will buy some of that to and see what that can do.
 
The cab is on casters atm. so not directly on the floor.
Found this thread, viewtopic.php?f=3&t=102888&start=50 allthough my CAB is not in pine (Plywood), it is basicly the same issue.
Will try the padding, and maybe switching the G12-H30 for a Vintage 30...

Any other tips?
 
I can't imagine a 2X12 with those speakers having too much low end. Sounds more like the room having more to do with that. I agree with getting the cab off of the floor. That should take care of the issue.
 
you said you raised the treble, have you tried lowering the bass on your amp? What amp is it?
 
Yep the bass is sat at 09 o clock, and its a Bogner Atma. I didnt experience this with the 212 i borrowed from a friend (old echolette). This is the Zilla Studio Pro.
 
Well, I shall almost certainly getting a greenback to replace one of the G12H30's in my EVH 2x12" after reading this, sounds neat ;)
 
Well as i suspected the Low end "problem" is basicly when I am playing on low volume (at home), just came back from rehersal and didn´t feel that the low end was to much. But then again i realized (when we were done) that I had put the vintage/modern swtich to Vintage, and that makes the amp much more open and a bit brighter, and not so tight. But that also removes som gain so will make sure I have it on modern next time. Still going to try out some damping in it, just to see if it makes any difference on low volumes :)

More to come for those who are interested...
 
As others have said. Decouple the cab from the floor by elevating it a foot or two. Get it out into the room as far as possible and stuff the cab with something like batting.

Yep, that I will do. :)
 
Quick recap...

Just did a first test with padding, i used the stuff that you have in cars (http://www.biltema.se/sv/Bil---MC/Bil-t ... lt-369222/) and followed the instructions that pickroar gave on his blog (padded the bottom, back and one side). And it worked like a charm, I even got to give a tad extra bass, but this was exactly what I wanted. Now I can let the bass player do his thing again ;)

I did som recordings with the iPhone, it sounds pretty crappy but I belive you can hear just how boomy it was before (will post later). Now it´s taco time! :D
