Re: Joe's New Rig
Well, its end of day one... The rig sounds great... All vintage Marshall amps and a Freidman Dirty Shirley 100.. It is the first one made in a 100 watt format. The speakers are all 25 watt green backs... It is much simpler than my old 4 head switching rig.. All cabinets are active but only two heads are on.. Tomorrow we button up the cabling and make the final decisions..

The reasons you changed to EV's in the first place haven't got better. 50W or 100W doesn't make that much difference in destructive power or sound pressure level really. Apart from fragility from these speakers being such a low power rating , cone cry is the major bug bear if you are still pushing hard in to the power amp section. On a Les Paul B String 14th to 18th fret and G string 4th to 9th fret are the most problematic areas when detuned a semi-tone. Symptoms as I'm sure you willhave experienced at times in the past are dischordal ghost notes that many wrongly think are the amps power supply and notes that just drop out with no sustain as if you've just muted them. In the days all speakers were hand made entirely the inconsistency meant the frequencies of cone cry varied from speaker to speaker and in a 4x12 it was not ever that noticeable. Now they are all made to exacting standards by machine so the cone cry always happens at the same frequencies and in a 4x12 with new speakers it's more noticeable than an old cabinet with old speakers. There is trick to helping this out, but I'm not posting it up here and being responsible for people killing their speakers as it seems quite drastic, but it does work.
For 99% of guitar players they will rarely ever play at the volumes this is an issue, unless they are using an amp with a very stout power supply and a fast transient response. I have a 30W model that can exhibit cone cry in a 65W speaker at moderate club gigging volumes.
THe 12L is the only guitar speaker in the world that will not exhibit cone cry in these areas when pushed hard, even with a 150W amp.
I've tried over 70 different speakers. The strongest current Celestion guitar speaker is the Classic Lead 80 and that still falls a ways behind the 12L for cone cry.
Celestion made a speaker for the Ampeg VL series years ago that was similar to the EV. It sounded like an old Celestion but had the strength of a 12L. I have tried to get the Celestion rep. to dig out that design a reconsider it.
Will catch up with you in Novemeber at Springfield. Hope all is well.
Kind Regards, Alan.
