Can a 2466 run 2 x Greenbacks?

[slash-ed]

Yeah that's basically my question.

I know that Greenbacks are 25W, and thus 2x12" gives it a handling of 50W. Does this mean if I try and run such a cab with my 2466 I'll fry the speakers? Or because of the lower max rating for the VMs, is this a viable option?

I'm quite happy running V30s in my 2x12", but the tone with Greenbacks would also be something cool to have.

All help appreciated, thanks!

Of course not!!! You will not fry the speakers. Your amp will only do the power necessary for the demanding speakers. The opposite may damage, i.e., if you put a 1000W speaker cabinet with a 100W amp. It may be harmful for the amp; will saturate earlier, etc etc.

Respect impedances!

Well... taking into account that there is no impedance mismatch, let's talk about power handling.

Tube amps are famous for their peak transients. It is usual to have (thumbrule) cabs 2x the power of the amp.
You will be able to play with 2x12" GBs, but keep them in low volumes (1 or 2, max!). You'll most certainly blow your speakers if you go past that. And remember that with blown speakers it will be too easy to damage your amp (eg., output transformer).

This info is completely wrong! he WILL fry his speakers! The amp WILL NOT stop at 50watt!! assuming the impdences of head and cab are matched then the amp will "see" the load but will be blind to the power handling. it will put out 74-100watt and if the speakers arent rated for that they're gonna burn!!

and the part about 1000W speakers damaging a 100watt amp, also totally wrong. if impedances are matched, it would be fine! most of the modern 100watt marshall amps (TSL DSL JCM800) are all sold with 300watt 1960a cabs! that is to make sure they can handle the power from the amps! cos they usually put out more power than they are rated for!

I know right? I was like "what the hell" when I read that haha.

You guys are all right. My sentence is wrong. I apologize for that. I wasn't seeing an amp as a current source...

But you can use the 2x12 GB's cab just use low output level on the Master Volume. I think 2466 is rated max at 66W in "clean" mode...

You were serious? I thought it was joke

I measured my 2466 at around 80 watts clean into an 8 ohm dummy load. This will most likely hurt a pair of Greenbacks eventually. I once almost blew a single Vintage 30 (60W power rating) with my 2466 in a test; had the master volume turned down to a respectable level. It did sound good, but it started smelling as it heated up. Of all the unique smells in electronics, a hot speaker is one of the most unique.

You need to respect power ratings of Marshall amps; I witnessed the death of a mint EV SRO15 from a screaming early seventies 1959 100W head. It was very good and loud for about a minute or two, then it killed the speaker. IIRC the SRO15 was rated at 200W. Even running a 1959 head into a single 4X12 cab with Greenbacks would make me nervous. The hard square wave from a clipping power amp is punishing to a speaker.

The vintage moderns are better speakers if you ask me. The greens are great too, but for my they are too old school in sound.
The V's just have more presence, louder, more uppermids, cuts through the mix more, with a tad of modern voicing. I use the Mesa Rectifier cab with the V;s with my JVM410. very happy with this set up.

So basically the answer is no, damn, thought so.

GoldFacePlate - yeah totally nothing wrong with the V30s, but like you said Greenbacks do give you a more old school sound, which I really liked through the VM's matching quad. Unfortunately, I have absolutely no need for 4x12"s any more. Even when I did own them they were more for my own personal wank factor at the time than for any sonic reason!

The VM cab 425A/B contains G12C GREENBACK speakers... They G12M isn't very different at all and I believe Surf has stated that he couldn't tell much difference between the two.

This rule is correct but in the wrong sense, this is the rule for PA speakers and amps not guitar amps and expecially tube amps. Figured id make ya sound half right
