50-75W greenback-like speaker ?

[CB Amp]

Hello,

I'm looking for a single speaker for a 50W Marshall clone (an open back combo based on a 1987 head model). I woud need a single 12 inches.
I've tried some speakers and the one I prefer is a G12H-30W from 1970 (it's not a surprise of course). But I don't think it can handle all the power.

I would prefer to mount a stronger one. I have a Celestion Gold which is a good speaker, but after a year of playing, it's still a bit trebly for me (and I think I become tired of alnico speakers).
So I'm looking for a classic british tone. I never tried the Eminence, Tone Tubby, Scumback or Weber lines. There are so many models, what would be your favorites ?

Thanks for your advice !
Cyril.

Before commiting yourself to a particular speaker you need to ask yourself two questions.

Why are Marshall 50 watt valve heads usually sold with a quad box and 100 watt ones with two quad boxes.

What sort of speakers do Marshall put in those quad boxes.

If you are playing a relatively clean amp eg Fender then to ensure longevity of speakers those speakers should have a cobined power capability of twice the power output of the amp.

If however you a playing a high gain amp like a Marshall then they are generally played at relatively high distortion levels. They signal at the speakers is approaching a square wave shape. This wave shape is extreamly hard on speakers. Therefore to ensure long life for the speakers they need a combined power capability of five to six times the amp output power. So Marshall stick 75 - 80 watt speakers in their quad boxes for 300 watt capability.

So if you must have a single speaker then you need to be considering high power units. Look at Eminence Delta Pro 12A :- 400 watts rms or perhaps one of the Fane speakers. You may have to seach around for Fane. The Delta Pro is available from www.usspeaker.com

a 100w is more than sufficient. a 65w is risky. the scumback have that classical celestion sound more than the eminence stuff IMO

There is a bar in town here that I used to play the jam at every Sunday. Was fun for a while and I even found out that one of the house amps I was playing on was a homebrew Metro kit. Sounded pretty darn good through the guys 2x12 setup too. But it gets old when the amp owner lectures you every time because he's pushing a 100W amp into two 35W greenbacks and he's afraid to turn the amp up. He even told me that I couldn't use the neck pickup on my 52 Tele RI because it was "too loud" and would blow his speakers. Ain't that some dumb shit?

haha, 100w into two 25w greenbacks

From a technical point of view, I would have been very tempted to conduct an experiment to find out at what point on the volume knob the speakers would have blown.
