More watts and less omhs

[Downunderwonder]

The PA assisted aspect is important. Also the fact you might miss out on PA support on the odd occasion.

100W tube guitars is often a problem indoors. For you to hear yourself AND get PA support is requiring strategic cab placement unless they aren't using a quarter of the capacity of their 100w to tear heads off.

In any case you don't want to be louder than the drums on stage.

I am a 210 vertical stack believer!!

Although 112 and 212 cabs have blown up less in more recent times I would still be leery of 500w unleashed on 2x12 @ 4 ohms.

Does all of this advice apply to tube amps as well? Seems it would make no difference for the pupose of whether you'd buy a 4 or 8 ohm cabinet.

it would depend on your intentions and the available taps on the tube amp. Some are native 2/4, some are 4/8. Yes you get the same power out of the amp, but you still get +3dB if two cabs instead of one cab, and height advantage to stack.

Being a Grumpy Old Fart i’m allowed to nit-pick. The word is Ohm.

 

[vvvmmm]

The word is Ohm.

Ohm is the word.

Ooooooooooooooooooooooooooooooohm.

OK, I feel better.

(I didn't even notice the mispell!)

Enough of your Transcendental mumbo jumbo!!

Keep in mind that the 4 and 8 ohm versions of the same cab likely don’t have the same sensitivity. For example look at the the Eminence 3012LF driver, a very capable and powerful 12” woofer used in the greenboy cabinets as well as other high end models. The 4 ohm version has a 92.9db sensitivity rating, while the 8 ohm version has a 95.7db rating. What this means is that the increase in available power from your amp is needed to achieve the same volume.

True. This difference can be as little as 1 dB SPL in drivers where low end extension is optimized. It depends what factors the driver design is optimized for. Then you have to factor in 16 and 32 ohm drivers for some multiple driver cabs. Warwick 2x10s, for example, use two 16 ohm drivers.

Many of modern crop of 212s from GK, Bergantino, EBS, are rated to 600-700W @4 ohms. That having been said, it's probably worth mentioning that one *can* damage a 700W-rated cab with a 500W amp if the signal is nasty enough, and that there's nothing wrong with using a head that's more powerful than your speaker's power rating, so long as you're paying attention and backing off when it starts to fart out.

Perchance you don't understand ''leery'' and ''unleash''?

Where I come from, "leery" means something between nervousness and fear, while "unleash" means to use with serious intent. I could imagine there to be a nuance in New Zealand English where "unleash" takes on a sense of losing control and going over the top.

Buy 8 ohm cabs. If you only buy one now, later on the second 8 ohm cab lines it up.

800rb and a pair of 8ohm 15"

Indeed, as in unleash a dog. ( A lot of dogs take that as their cue to ''go for it'' even if there is nothing in particular to go for )
