31 band graphic to fix unbalanced cab?

That's probably much of the problem. Too large internal dimensions can lead to problems. EQ might help, but you might be trying to polish a turd with this one.

 

Borrow an EQ, try it.

 

sounds possible ...

 

You can always take advantage of a 30 day return policy on an EQ. Honestly though, I would get something better rather deal with more gear at shows.

 

How much is turd polish these days? Does it come in odor blocker gold?

 

Out of phase with your regular cab?

 

Forget the cab, and run through the floor monitors?

 

Fixed NO, made almost tolerable yes. Finding out what is fixable with the cab would be better time spent. Air leaks, drivers out of phase, adding at least a center divider. I know its not your cab..........you may find yourself spending more time with the EQ than your bass unless you have a white noise generator, reference mike and spectrum analyzer.

 

Hi.

I have used a 31 band EQ to even out cabs, but most often it's a pair of ancient Russian 15"+12"+2*1" PA-cabs with pretty complicated cross-overs. The result is "better", but then again it's not that bad to begin with, I have no problems running 'em without an EQ.

Just as BFM said, try before You buy, I for one wouldn't get my hopes up.

You may spend a lot of time without getting satisfied. Get Yourselfe some good, stable, average used cabs (like the Peavey TVX 410). Two of them will do the job for a reasonable price.

This will make more sense than getting an EQ and spend a lot of time.

I once made this mistake, but this is 30 years ago. The cabs affordable to me showed up seldom, and so I changed a DIY- 215 to a Marshall 118. Such a big cab! But it soundet awfull with my setup. So I tried it witha active, graphic EQ, I think at least 22-band. The effect: I spent my time on the floor, playing some tones, twiddeling around with the EQ, playing, twiddeling.... I lost valuable time by trying to get some tone.

So I collected money from my apprenticeship wage and bought me a reasonable cabs and an amp. Wow, this was it! First time I had a real good sound!

Play Bass!

 

A multiband parametric EQ might work better. Seriously though, it sounds like you need a different cab. EQ is great for removing problem frequencies, and for a little boosting. But if you need a lot of EQ, especially if you need a lot of boost, then it can start sounding artificial.

 

In 30 or so years of gigging my track record of success for fixing an issue by beating it to death with EQ is exactly zero.

 

Word. A little EQ is very cool, sometimes even a lot of it, but if something is so far off that it requires a 31 band to fix it to my liking, I'll pass. Having said that, a decent parametric or even a smaller graphic wouldn't be totally out of the question for me. But definitely try before you buy.

 

A small 3 band line-level PEQ may help tame things down. I hate to see you spend $$ to "fix" something that isn't even your's and used only occasionally.

Panel distances far enough apart to get peaks and nulls in the "meat" frequencies?

 

Yes.
