Changing speakers in a cab?

[Mastering101]

I have a marshall 1922 cab that’s wired 8 ohms mono 16 ohms stereo.
I want to change the speakers to celestion vintage 30’s which are 8ohm.
And I want to run the speaker in stereo at 8 ohms per side for my mesa
2/90..what I want to know is what to do to change them?.. Is it a matter of just switching the speakers. And I will be at 4 ohms mono and 8 ohms stereo? Or will I have to wire these? Thanks for any help

Assuming the old speakers were 16 ohm, putting these in wired the same way should work just as you hope.

Make sure to keep track of which leads go to + and which to -.

Dude, don't bother modding that cab, its piece of shit!

I know, I owned one. The wood is particle board

Its not in the league with your H8000, lets put it that way.

Just sell it and get a Mesa or VHT 2x12 and wire that for stereo.

Or get the Mesa 3/4 back 4x12 - it comes wired for stereo and mono.

They all come with V30s.

And nice, real wood.

well i was just gonna stuff it in a isolation box.but i think its real wood ..im gonna open it up...

you were right...heres the wiring

That does look like particle board. But if you really wanted to upgrade, I'd consider two cabs. I don't really like the sound of a single cab wired in stereo.

Prismatic,im going to put this cab in a amplifier enclosure so i can only use one cab
and i want to run stereo... if you look at the wiring do you think i'll have any issues
switching them out.. if i put the the 8 ohm celestions in it will be at 4 ohm mono
8 ohm stereo right?

The man had a point, a stereo 2x12 is cool for your bedroom but the audience won't get much of a stereo effect onstage. Maybe go with a pair of 1x12s instead, but hey, you not listening to me anyways.

Rock on!

i read your post and hear you cdog.. i know its a piece of junk. i figure it will sound fine with the vintage 30's in an enclosure...i checked out the vht 2x12's
do you know if they are wired for stereo and at what ohm? the vht site sucks..
i was also considering a custom cab from earcandycabs.com...the mesa 2,12's are wired for mono..im still not sure what i will do

Wise words from a wise man.

Sell it and get some good wood...it does make a difference, well to me anyways

It looks like an easy swap that would give you 8 ohm stereo or 4 ohm mono. Hard to mess up: Red is +, Black is -.

If the Celestion "Vintage 30's" are 8 ohm speakers then you'll end up with 16 ohm mono and 8 ohm stereo.

Each speaker is 8 ohms. In stereo they run independently. One side of stereo being 8 ohms, the other side of stereo being 8 ohms.

In mono the speakers run in series... which will add up to 16 ohms [8ohms +8ohms= 16]. You could wire the two speakers in parallel to the mono jack [one set of leads from Tip & Sleeve to the + & - terminals of the speaker] which would bring you down to 4 ohms in mono [8 ohms/2 speakers=4ohms].

Whether the cabinet sounds like shit or not I neither know, nor care. One thing I will suggest [as I do it all of my speaker cabinets] is to remove the wire inside the cabinet and replace it with like 10 or 8 awg. wire... the speakers last longer if the full output of the amp can get to them. Why? I dunno... but you can definitely hear the difference with the larger gauge wire and my speakers have lasted longer without going soft so I figured I'd share the discovery... do what you will with the information...

Check this guy out. www.swansoncabinets.com Everything is made from Baltic Birch ply and has dovetailed joints. Indestructable. I believe he is in Ma.

thank you..im calling him today..i looked at his pic's he does great work..good price too.

well they could be made to 16 ohm mono, but if he just uses the stock wiring (uless i'm mistaken) then it should come out to 4 ohm mono. If it's currently 16 stereo and 8 mono, right? If it was wired so that the two 8 ohm speakers created a 16 ohm load, then the current 16 ohm speakers would (with all wiring the same) have to equal a 32 ohm cab... and yes, effectsnut, it would be a really simple replacement to switch out those speakers and that is the exact result you would end up with, but always smart to ask. I can say too that cheap wood is an easy way to kill the tone of the cab, you can crank your amp but it just won't have all that punch. If you like a dark, dull sound it may be just right though. Also keep in mind, just as easy as it is to replace those speakers, it would be likewise as simple to put them in another cab later if you buy a nice empty one... you've got some good feedback in this thread though, good luck.

the cab is wired 8 ohms mono 16 ohms stereo now.
I want to change the speakers to celestion vintage 30’s which are 8ohm speakers. i do not want to mess with the wire.. im hopeing after i install the
vintage 30 8 ohm speakers i will be able to run them 8 ohm stereo with the original wire...i plan to have a custom cab but it seems these shops are 6 weeks out...so for now i want to do this..thank you!!

ok then,,,i just bought a 2x12 cab " Baltic Birch wood "here http://www.swansoncabinets.com

sent a check today.so no cab problems..thanks to Colin Gaucher

[Mastering101]

ok, heres my new swanson cab thanks to Colin's post

I did this at Hit when I opened up a cab and saw the teenie wire that came stock. I put in good 10 guage and fixed the connector I originally opened it up to repair. A client came in a week later to fix some stuff gtr tracks they did before I replaced the connector and wires. They were callin all over to find out what 'mod' I did to make the rig sound so much better. I was like, I didn't do anything to it. They retracked more than they originally planned and when I spoke w/ the assistant later, he said that I told them "I wouldn't tell them the mod I did, it was a Hit Factory secret." I was like, what the hell, I told em I didn't do anything, the only thing I did was change the wires and the connector on the cab, I didn't even touch the head.
So, go crack open your cab and throw some real cables in there
