My thoughts on Marshall cab

[SeraphimTN]

Ok well, I've had the Marshall cab since Tuesday and played the crap outta it since then. Now, I've used a H&K cab that matches my Attax head for years and it has a very present tone, like the kind of presence Paul Gilbert talks about having. Half my tone is presence and bite. The 1960A is the complete opposite to my ears. It almost sounds a little stuffy compared. It alone I don't particularly like for a show where there isn't any mic'ing. Now when mic'ing is required, this thing would sound better and more even for sure. The real awsome thing is that now I have all the sonic spectrum covered. The H&K cab covers the midtop and top end crunch and presence while the Marshall smooths out the bottom and adds a ton of depth. Together, these cabs OWN. Such a warm chug sound. I do n't know how to explane is other than very organic and woody sounding. Talk about a full sound, reminds me of Rage or Nightwish. I'll be mic'ing both cabs at our New Years show to see what works live.

You should get six more of them, then start a conversation with Ace Frehley.

Re: My thoughts on Marshall cab

nothing like playing thru a complete 2 cab stack..... but if you use both cabs at shows i bet they will not Mic you... that is a lot of volume coming off stage... for shows i'd use only one cab and keep the volume under controll... your out front sound will be much better if they mic you every time..

But that being said... it is a hell of a lot of fun playing thru a full stack...

Is your Marshall cab equipped with the standard G12T-75 speakers?

Yessr! Since my band runs the sound and we have our own gear, running two cabs on stage is fine. I don't turn up very loud in the first place and you gotta remember, the Marshall is quieter due to the wiring issue between both cabs.

Re: My thoughts on Marshall cab

What do you mean by "wiring issue"? If it's an impedence mismatch or something else like that, get it fixed before using both cabs again. You'll risk hurting your amp.

They're both wired at 16 ohms but the speakers in the hughes are 8 and the marshall is 16.

How is the Hughs wired for 16 with 4x8 ohm speakers? It can't be done.

The Marshall is wired series/parallel with 4x16 ohm speakers making it 16 ohms. If the Hughs is wired series/parallel, then it's an 8 ohm cab.

2 and 2 wired to the output. Top wired to bottom and the two bottoms wired to the output.

Draw up a diagram.

Edit: Or better yet, which one on this page does it look like?
http://www.usspeaker.com/speaker wiring-1.htm

Got a digital multi-meter? Plug the speaker cable in and then put the probes on the tip and sleeve at the other end with the meter set to read ohms. That'll tell you exactly what the load is.

Re: My thoughts on Marshall cab

No idea what to set the meter to. There's diff settings in ohms. I put it on the one with musical notes n it told me 2 ohms. surely not right. I have on each side individually....the top wired directly to the bottom speaker then the bottom speaker wired to the output.

Re: My thoughts on Marshall cab

Set it for a setting higher than what you're looking to get, like 16 ohms. Then check it.

So is this way?

top plus to bottom plus
top negative to bottom negative

Or

top plus to bottom negative
top negative to bottom plus

A diagram would be great and answer it all.

Re: My thoughts on Marshall cab

I actually dont know. It was already wired that way when I got it, i jst moved it to one output. What's the difference in the 2? Would either give me a reading of 2 ohms?

That cab has 2 outputs?

What's the model number of it? I might be able to find the specs.

What do you mean you moved it to one output? Both sides (top and bottom) to one output?

It's an Attax cab, fuzzy version. It was wired so it could do stereo, so I got rid of the second jack and wired it just to one simple one. Both sides to one output. Sorry if I'm not much help. I was told that wiring 2 and 2 then one from each set to the output would give me 16.

Nope, not happenin'. I found some info on the later tolex versions. Looks like it had a panel with 2 jacks, one being mono or use both for stereo.

In it's stock form: In mono, it's an 8 ohm load. In stereo, it's a 4 ohm load. This means that each pair is wired in parallel (4 ohms each side). They are then run in series/parallel in mono (8 ohms).

With what you did, you essential wired both pairs in parallel so your meter read right. Two 4 ohm loads in parallel makes 2 ohms. This is not safe for your amp.

I highly suggest you get the cab rewired correctly the way it was. If you don't want to use the second jack, simply leave it alone.

However, what you *really* need to do is decide if you want all 8 ohm speakers or all 16 ohm speakers and reload one of those cabs. I recommend reloading the H&K with 16 ohm speakers so when they are both hooked up to your amp it sees 8 ohms (speaker jacks on the amp are wired parallel).

For now, use one or the other, not both. Actually, use the Marshall only until you get the H&K taken care of. The minimum load your amp can handle is 4 ohms. Consider yourself lucky that it's still working.

There's got to be a way to wire the Hughes so both cabs will work. Even if there is a volume difference.

Not with 4x 8 ohm speakers. The best you can do with what is in there now is wire 2 of them in series so the load is 16 ohms leaving 2 disconnected and not in use. Then you'd have 6 speakers at least and a safe load for the amp.
