Cabinet for EVH 5150 III Stealth 100W

[griff10672]

all the maths aside .... I always called it " Math " the manufacturer suggests you use the cab they built to go with it ... kind of a no brainer

and in case no one knows ..... a wattage rating of an amp is the rating for " CLEAN POWER " dimed

if you're running her hot ..... you can hit 150 watts of output .... ( that's dimed of course )

so what do you do there ? with your 100 watt cab ?? how the maths work there ?

So Ohms law and Joule's law is basic math?

Ohms law: V=IR. There's a single multiplication. If you flip it around to solve for I or R there's a single division.

Joule's law (resistive heating) isn't super important here - what you really want is the formula for electric power - P=IV. Again, simple multiplication and division. If you get all crazy and combine the two you can end up with a squared or square root term.

You'd also want the formulas for impedance in series and parallel. The first is just addition, the second is addition and fractions.

Basically nothing I wouldn't expect my 4th grader to get right, but she is better at math than the average 4th grader.

You're stupid

True but ain't an "expert" like you champ

The math works the speakers might blow. Which is the reality with a 100w amp into 4 greenbacks whether listed at 20W or 25W.

Google AI gave me this ........... I was close ... you can hit 200 watts of output

Solving the formulas is basic algebra, but understanding them is more than basic math. I guess on surface level plugging numbers into the formulas will get the basic info, but if you want to know what those numbers actually mean you need to go beyond math.

And you're right about the power formula which also applies. I was thinking Joules law in the terms of current going into the voice coil and thermal heating before it starts to melt.

You don't need AI to understand that 4 multiplied by 20 watts doesn't equal 100 watts. It equals 80 watts.


Maybe AI is using some Nu-maths but again as far as I know maths hasn't changed and AI doesn't change basic maths or the understanding of it

 

[The~Kid]

Also @griff10672 I'm pretty sure the 200 watts of output is in reference to the amp not the cab..... So I mean if this is supposed to be an argument it only supports my argument further and AI is right there.

So basically what everyone except Kid has been saying as far as the OP's question is concerned. The EVH 412 cab will be just fine for bedroom level playing. If OP decides to play with a full band and/or dime the MV he might want to consider higher power cab options.

No again...... Youre even more fucked as the amp can push 200 watts and again your pushing into a cab that max takes 80 watts......



It only reinforces my argument more that it's completely unsafe.

At the volume it is a problem, just use 2 or 4 of them

All the best tones are from working the speakers. All the best things in life come with risk.

If I was broke, I would be afraid to break something. Fortunately, while not a millionaire, I have enough cash to replace a speaker or cab with ease if I need to.

Nvm some blindly follow the "experts" right and dismiss and ignore basic maths and common sense....


Now we are saying thanks to the magic of AI that a cab can magically handle more than what it is rated at and for.... Defying basic maths, science and physics while you're at it and somehow rationalize it.....


But nvm what a schmuck like me has to say, nvm basic maths and common sense... Let's just throw out everything out the window including basics and fundamentals of basic physics and just say fuck it you can use a 110 cab with a 40 watt speaker and pretend it can safely power a 200 watt head.


As long as you believe it in your heart it can't be a lie and must be true *_*

 

[Mike Oxhuge]

My policy on speakers is I'd rather burn em up than have them fade away. Seriously though unless you are a touring pro getting your master volume consistently over half way every day, you probably won't blow any up, and when you do you get street cred.

Just give it up. You're out of your league.
You're the stereotypical TGP turd who parrots something he read on the internet once and has zero first hand experience. As evident with your comment about being able to gig with a Roland Cube in that other thread.

your missing the point totally ............ How many amps have you built ???

Listen man .... I know if I have 100 peanut butter sandwiches and someone takes 20 away from me .... I'll only have 80 sandwiches left ....

or if I have 20 pizzas and cut them into 4 slices each .... I will have 80 slices

etc etc ...

so I know myself personally am up to speed on how to get to 80

this will be my last say on the subject

if you are running your hi gain 100 watt head full open ..... you can hit 200 watts of output

but yet no one that I ever heard of is blowing one of these cabs up

there's some Math there ... in between the lines ......

A cab cant magically handle more power than its rated for....


It doesn't create power either it just receives it..... And yeah a 100 watt amp can push 150-200 watts and this is why it isn't advised to use a cab that is lower wattage than what the amp is rated at.


You are essentially just magically making up shit now and magic logic to explain basic science and physics now.... Nvm basic maths and common sense in favor of magical thinking

An amp at home volumes is putting out like 5W, which is far less than 80. It is only an issue if you are cranking the amp to stage volumes where you can't stand within 10 feet of it.

And your advice is like the dipshits driving alone in their car with a kungflu mask on. Maybe you should wear a condom every where you go just in case as well. Can't be too careful.

Great..... Run your 100 watt head through a 40 watt speaker..... Good luck *_*
