Why are there 6ohm cabinets

To save searching maybe someone can remind me what a little less impedance does to the tube stage. I recall only that a little too much impedance draws extra currrent through the tubes.
A higher cab impedance will develop higher voltages with less current draw; a lower cab impedance will develop lower voltages with more current draw. Google Ohm's Law.

Maximum power transfer occurs when output and input impedances are equal. Slight mismatches always reduce transferred power, with either higher voltage (higher cab z) or higher current draw (lower cab z).

First thing I thought of when I saw this thread was this. Kustom used 16 ohm speakers almost exclusively, and the 3x15 cab was real popular among bass players. I'm sure many of them never realized that a) the head, rated at 100w into 4ohms, wasn't putting out all it was capable of and b) that cabinet didn't have enough room to do those 3 15s justice. Still, they sounded good at the time, and looked cool, so who cared?

Says the guy who links to an "ibook" in his signature. Irony much?

How much TV did you watch as a kid? Did it "rot your brain" like your parents told you it would?
Great observation and point taken.

I do see a difference between the relatively limited penetration TV had back in the day to the instantaneous/massive influence the current technology has. Whereas most logical beings would think that this technology should have made us evolve into a more unified humanity, it seems we are first taking a step into the opposite direction. Another observation is the instant short term gratification (just googling something) which is rendering our study muscles to atrophy. It is getting rare to see normal folk investigating, even reading a book.

This concerns me, as we are getting more vulnerable and easy to manipulate. The signs are everywhere, but you can just look at music in general and pretty much get to the same conclusion.

Or not, and I could be totally wrong.

Amazing what a question about 6Ohms can spark, only here in TB.

Not gonna say there aren’t very real risks and concerns associated with the “always on” culture, and certainly there are unique and interesting problems that the algorithmic news cycle has that traditional media didn’t (though the reverse is also true).

But there’s a cognitive dissonance exemplified by your post that seems endemic to the “kids these days” argument against technology - you say in the same breath (to paraphrase) “it’s too easy to google search” and “the ability to research is atrophying.” This is not indicative of the ability to research atrophying but adapting.

Think of it this way: Who cares if the kids aren’t learning the dewey decimal system if no one ever needs to use it again?

If the answer to every question you’ve ever asked is at your fingertips, and suddenly you find one that isn’t, sure, maybe you just give up and accept that the question is unanswerable. Or maybe you realize now it’s time to get to work really finding the answer since this is work that’s actually worth doing, and make sure that information gets diseminated so the next person to ask that question doesn’t have to work as hard as you did.

explain what goes on in the tubes with high impedance cab.

I am not that old, but this did make me feel this way; I want to clarify that by “generation” I truly meant “large group of people”: I was not in any way relating this to age.

What is new this time around, is that the very tool used to deliver answers has the instantaneous hability to both lead you to conclusions and has, because of this, a layer of addictive attractiveness no previously-designed media had before... i think we both recognize that. I feel the “powers” know and use this extensively.

In essence, the more kids ignore the dewey decimal system, more dependent they are to use the tool, which feeds the loop of ignorance-dependency-massification-socialization-of-the-banal. We could be in a loop of regression, adapting to take the path of least resistance, the exact thing that hinders intellectual evolution.

I am amazed at the possibilities, yet I believe we are yet to intellecually evolve to match the potential you identified. I hope we get there one day.[/QUOTE]

Totally, and I think you encapsulated it in your earlier post when you said our "first step" has been in the wrong direction. I would just contend that actually we're moving in the right direction, but we have to move through some darkness before we get to the light. It's only by burning down that we can build anew - atrophy the obsolete so that we have room to create, grow, and adapt the tools and skills that will serve us best.

We're definitely experiencing the growing pains right now, and it's very tempting to point at the pain and say "see, this is wrong," but I think that kind of shortsightedness too often holds back the march of progress.

The "path of least resistance" is what in engineering we call "good design." If that path leads to the "wrong" outcome, there are two possibilities, 1) there's actually a path of even less resistance that we need to carve out, or 2) our definitions of right and wrong are antiquated and need to be updated.
