My celestion v30s suck, and I don't know why.

My used marshall cab that I bought that came with celestion v30s in replacement of stock speakers don't sound good, I can't even get them to feedback nearly at all, and I've got another (pair) of possibly marshall voiced v30s, 8 ohms (these are 16), that kick the living shit out of them, at least they did the last time I listened to them compared to these, no idea why, any thoughts, ideas or suggestions?

Can't get feedback where you did previously...
check your resistance / you might have a pair of 16's wired to be 32 ohms

Did you check the wiring? You got a meter? Check each individual speaker and total cab impedance. Something is wrong...

Well I never got it specifically well previously, the speakers where wired to the cab when I bought it, used, ordered in from a store, all I know is, my other vintage 30's rock life. can't get these to sound better than muffled bullshit, no offense celestion..

If there's something seriously wrong and I can prove it, I have it under progear warranty for over a year, I could prolly get them replaced

Re: My celestion v30s suck, and I don't know why.

If it sounds like sh*t, take it back.

I have had numerous vintage 30's over the years...and mixed them with G12H's, etc...and when doing so, I would notice one cab sounding nice and fat, and the other sounding thin and irritating in the mids.

I played the individual speakers with wire clips, and they sounded different, even though they had no voice coil rub, or other issues.
...same with the G12H anniversaries.

Some just sounded like crap, so those went on Ebay....
Perhaps you have one or two in the cab that don't sound right, and that's enough
to make the cabinet suck.

My two cents...

Oh sorry, I was actually recommending Mesa V30s. I reread your post and confused myself the first time.

Put your other V30's in and see how they sound. If the same problem it could be the wiring.

Thanks. Their all pretty much identical, maybe not 100% sound wise, what about wire clips?

Re: My celestion v30s suck, and I don't know why.

Try electronics contact cleaner on the plugs and jacks.
Check total resistance with meter if possible, like mentioned.
Make sure all speakers are in phase. Put a battery, 1.5V or 9V, pos and neg to the cabinet speaker cable's pos and neg on the plug. All four speakers should move forward or upward in unison.

Re: My celestion v30s suck, and I don't know why.

Every amp & speaker combination I play thru sucked.

Then I realized it wasn't the amp or speaker...

New cab probably needs to be broken in...crank that effer for a week or two and see if they smooth out...otherwise take it back before warranty period is over.

Your speakers are out of phase. Check the wiring.

Re: My celestion v30s suck, and I don't know why.

Really easy to tell if they are out of phase...

Generally will sound thin and tinny with no bass.

Use a 9V battery and see if they are all moving in the same direction when touching the terminals to the battery...

So you like lower quality speaker cabinets?

Hmmm let's see...
Quality always means tone right? I mean clearly building thicker cabs or different materials sounds the same as other materials right?... Oh yea, that's tone theory 101...

*Facepalm*


Obviously, Marshall's cab quality is junk considering how many old cabs are still kicking ass.. I really wish I could grab one of those 1968 Mesa Rectifier 4x12 cabs... their quality is second to none.

It has bass, just not "Real" bass.. if ya know what I mean..


Maybe I should try wiring it up (on the plate) reverse the way it is, see if anything changes.. What could go wrong?

Yes, they might have the ground as the hot lead; try it. It won't hurt anything. As long as you're sure they're in phase (which surprises me) just reverse the two wires at the jack.

You might also try playing through them one at a time; leads with alligator clips will make this fast and easy. You might find one that sounds weird compared to the other 3.

Yes, I was. I explained it in the auction, how they all sound different, etc.
And, my feedback in 13 years is still 100%, if you need to check.

But thanks for making sure to get a dig in...I am about outta here, too.
I thought after 35 years of playing with this stuff, I could help others out
with my experience...like the OP.
Shit like this gets old...it's supposed to be fun.

Re: My celestion v30s suck, and I don't know why.

It's more than just two wires though, it's four that connects up to the backplate. I reversed them, and got a "different", yet "better" sound, oddly.. but I'm not sure it's the correct way it's supposed to go, maybe it just wore through a previously unworn part of the speaker and added a few extra harmonics, not sure, think im gonna let it rest for a little while though until I can figure out what's best for it.

There are 3 different version of the V30 and are voiced differently. There is a version sold to Mesa for their gear. A version for Marshall and a version for aftermarket / everyone else. Its entirely possible you are just hearing the difference between different versions of the speaker

Re: My celestion v30s suck, and I don't know why.

That's what I had originally thought, although, after reversing the wires and playing for a little while, returning it back to original set wiring has given it a slightly more defined sound, it sounds like it's resonating more, and I can hear the reverb better and some extra harmonics it seems; that might be that it's loosening up the voice coil some more by using it in a way it's not normally used in, and adding dimensions in. Think I might redo that wire switch for a while and crank it a bit, then switch it back; see if that opens up the speakers some more.

..That's strange, I just noticed that the v30's that I cherish, has the serial number of a Mesa speaker...01FB(or8)T4335/1(8)

Maybe it's truly that im just enjoying the sound of a very well broken in speaker, and I liked the mesa versions afterall...
The guy who I bought them from, was buying some "warehouse guitar speaker" replacements to combine with his two other v30s, and sold me the pair he was getting rid of, ironically his amplifier that he was using was also a jcm2000 so it could be the shoe just fit perfectly.. Wish I coulda bought the other two off of him.

But if that's the case, and the speakers just need to be worn in a lot more, all I'd have to do is wear these in better, and I could get a similarly better sound.
