Diezel 2x12 cabinet watt questions (newbie)

[soonforgot]

Hi, brand new here and very new to understanding amplifiers and the way they work.
All i know is that my Hiwatt that i had was not good for me anymore and the VH4 i tried out was amazing and a lot more fun to play. I have a few questions for the experts here.

I am in the market for a VH4 and I recently got a Diezel 2x12 cabinet with 1-Vintage 30 8 ohm 60 watt speaker and 1-Tophat G12C 30 - 8 ohm speaker 30 watt. This of course was someones creation. I'm thinking this will not be able to handle the VH4 because of the wattage. Am i right?

I read that the VH4 is a 100 watt amp but then on the some specs says it ranges between 90-160 watts. Is that fluctuation in the wattage because of the different tubes that could be used in the amp? If i trade out that Tophat for a new vintage 30, will i be able to run the VH4 on that cabinet ok?

Sorry for my kindergarten questions. I will really appreciate anyones knowledge on this situation.

Thank you!

your cab that you have shouldn't be able with a VH4
just don't crank the hell out of it. you are also correct
the wattage can change with different tubes.

number of speakers multiplied with the weakest of them.

In your case 2x30 = 60 Watt.

You will be able to use that cab as long as you don't crank up the volume too high. Assuming you only use it at home then you won't have a problem because if you get the cab outputting 60watts your ears will bleed and the neighbours will kill you.

As you raise the volume you'll hear the sound of the speakers change as they start to move, speakers really come into their own when they start 'pushing air' ie you see the speaker cones moving and not just vibrating a bit. They also start adding their own distortion to the sound.

If you start to overload the speaker it will start to 'clip' the sound, and you know you need to back down.

If you want to play the amp full bore then ideally you'd have a cab rated 150% to 200% of the amp output. This isn't a rule, just a guide, there are too many variables to be exact.

Just a quick point to mention, the amps output is not linear with the volume control, each amp is differnt, but you may well be putting out 80% of the amps power when the volume is only at 60%, so don't use that as a guide.

Oh, and I'm no expert, so if I'm talking crap I hope someone will put me right.

where to read the power of each speaker?
I'm having troubles finding the specs of my 2 speakers inside my Marshall tlsc212 cab.
How many v30 there are? I read some are 30w, mine maybe 80 or 100w
Mine has a total power of 140w.
Speakers inside are a marshall-celestion v30 and a Marshall-celestion heritage, not specified model and single output power, though....
I guess the heritage is 70w and the v30 80 or 100w.
On the celestion page specs are confusing....

Thank you for all your advice

I will be only using it at home and maybe take it around if i get off my ass to actually take my music out of the home.

Basically, i dont need to replace that speaker as long as i keep the volume low? Say if i crank the gain on channel 4 and kept the master volume low my cabinet should work ok?

Thank you!

Yeah you should be fine.

If in doubt, build your sound slowly, when the speakers start sounding bad, back the volume off.

You could also look at getting an attenuator, not required, but just an idea.

V30's rated at 70w IIRC, as v30 loaded 4x12s have a 280w rating. Heritage must be the same then.
