hey, i am considering downsizing my 412 peavey valveking to a 212 avatar cab, i was wondering what kind of speakers will be necessary so that everything is good for watts and ohms etc

here are some specs on my head:

100 watts (rms) into 16, 8, or 4 ohms (switchable)
Four 6L6GC and three 12AX7 tubes


and avatar speaker options

Custom Assembled Contemporary $379. with your choice of
Celestion: Vintage 30s, G12H30s, G12T75s, Greenbacks, Classic Lead 80s, Hellatone 30s, Hellatone 60s and G12K100 -16 ohm



Price with Alnico or Heritage would be as follows:

Any Heritage combo (G12H, G12M or G12-65)

$569. plus $34 shipping



Alnico Golds or Blues $729. plus $34 shipping



Choice of 4 ohm cab, 8 ohm cab, 16 ohm cab, stereo cab or mono cab.




i would like to stick to the first category because of price.. anybody know what will be required for my cab to match well with my head? im a technical moron so any help would be greatly appreciated


thanks

you are limited by your power. from list "a":
Vintage 30s, G12T75s, Classic Lead 80s, Hellatone 60s and G12K100 -16 ohm


the G12H30 and "greenback" would be shredded from 100 watts into two of them. plus, if you overdrive your amp much, remember that the amp can put out substantially more power than the 100 watt rating.

so any of the other speakers would work? should i get a higher wattage to be safer?
 
what kind of sound are you going for and what kind of music?

hard to quantify without a particular direction.
a
 
not really anything specific, id like to have a little bit of a deep kind of sound, but at the same time i would be playing strokes-ish type stuff through it,
 
so vintage 30's appear to be 60 watt speakers, with 8ohms or 16ohms, so i know the ohms will work cause i have a switch on the back of my head that is either 4, 8, or 16 ohms

and even though it is a 100watt head, its ok to have 60 watt speakers?

Contemporary 4x12 so the 4 60 watt speakers combined will give you 240watts
the 212 would be 120 watts so yes you are safe to drive either cab with your head.
 
sounds good

im thinkin..

212, 2 Vintage 30's, 16 ohms, stereo

then obviously colors and stuff but that doesnt really matter for sound or techinical issues obviously


thanks guys

Just a suggestion but I would go with 8 OHM and if later on you wanted tog et another avatar you could bridge another 8 OHM cab for more power you would still be safe with a 4 OHM load.
like I said its just a suggestion
 
just curious, what would i be losing by going to 8 ohms? i assume power, but i dont think i'll need more than a 212 you know, so should i just go with 16 if i know im most likely not going to get an extension cab?

using an 8 or 16 OHM cab you will not be using the head to its full potential but if you don't usually dime the volume knob anyway you probably not notice much of a power loss.
however you will have to turn up the gain more than usual for overdriven sound.

how could i get its full potential? would i need a second cab?

you get the amps full potential by using a 4 OHM cab

You know, It realy doesn't work that way with a tube amp. When you plug into the 4 ohm jack, you are plugged into a different tap on the output transformer. That negates the whole premise.

Running a solid state amp at 4 ohms will give you 3db spl more volume than running it at 8 ohms, but it doesn't work that way with tube amps as long as you are plugging the cabinet into the right jack.
 
so should i go with the 8 ohms? and just keep the impedance switch on 8 ohms instead of 16 ohms?
 
Yes. That way you can add another 8 ohm cabinet if you ever need to. If you have a 4 ohm cabinet, you can't add anything to it.

i must say that i subscribe to the idea of getting max power from the amp using a single cab. i am too much of a puss to lug multiple cabs. i have a 1x12, a 2x12, and a 4x12, all wired @ 4 ohms for use with fender amps. likewise, a 4 ohm 1x15 cabinet for use with my bassman 100. very very recordable amp, but the stock cab is huge (yet still sounds small??).

FWIW.

I thought we was talking about tube head...
I think you are misinterpriting what I posted
I am not suggesting using an 8 OHM cab and using it in a 16 OHM out
either you are misunderstanding me or I am misunderstanding you:confused:

And yes that is exactly what I said in another post however if I did not plan on getting another cabinet in the future I would go ahead and get a 4 ohm cab...
but I am with you, I like to leave the option open.
basically what I mean is if I was planing to use the Cab for strictly the purpose of a small gig or practice and do not need the extra headroom I would get a 4 OHM cab..
now if I was wanting to build a double stack rig I would get 16 OHM Cabs otherwise I would not bother with just just one 16 ohm cab.
hopefully expounding on my explination makes it a little more clear of what I am trying to say.
:D
