No. Keep your electrons lubricated!
So, don't play certain notes?
Yes. The friction makes the electrons go slower. Since different frequencies have different wavelengths, some of the electrons may arrive later than others and your harmonics will be out of sync with your fundamentals.
This is a great solution if:Purely anecdotal and not related to your amp, but I ran a hartke lh500 at 2 ohms for quite a long time, and it's still kicking.
For me, I'd just run it and see what happens. if it works, then it's fine. If it goes up in a ball of fire, then it wasn't the right product for my needs, and I know not to do it again.
Z=Xc+Xl+R
For all practical purposes, R that you measured is the minimum Z.
They exist-- big but not heavy. As I stated in another post- another speaker in series would work better by producing sound instead of heat.Imagine how big and heavy a 1 Ohm 400 watt resister might be if such a thing existed.
I remember working with imaginary numbers in high school calculus, but some of that other stuff that you so kindly summarized for me would take weeks of reading and many head-scratching sessions for me to understand. I do appreciate it, though -- suddenly the electronics "lab" that my folks got me in elementary school seems full of untapped possibilities -- and will try to understand some of it, though I make no promise to grasp the whole any time soon.
Size of resistors are mostly about how much heat they can handle. I have a couple of 10,000 watt dummy loads at work. The resistors in them are 500 Ohm, 1000 watts each, and they are non-inductive, which really ramps up the price tag. Each resistor is about 18 in long and about 1-1/4 in diam. Each load has 9 resistors.They exist-- big but not heavy. As I stated in another post- another speaker in series would work better by producing sound instead of heat.
interrupting to share a couple of thoughts...
perhaps get another g-k to run as a slave amp? buy used to save a few bucks.
adding another cabinet will help you achieve more 'perceived volume' even if you run it at the higher nominal impedance. i.e. i expect 6 speakers at 12 ohms will be noticeably 'louder' than 3 speakers at 6 ohms.
I have a 6 ohm 310 and just ordered a second one (Berg HG310). I know I can run them in series for a 12 ohm load and then use them with virtually any SS amp.
The amps I have are only rated down to 4 ohms. Is this similar to the situation with watts in that you can overpower a cab so long as you use good judgement and common sense? Can I hook them up in parallel for a 3 ohm load and not worry about my amps going up in smoke if I don't push too hard?
Also, what about pairing with an 8 ohm cab (Markbass combo amp) which would result in a 3.5 ohm load?
GK tells me I should be ok with my Fusion 800, but the protection circuits may kick in if it's pushed.
I'm sure @agedhorse has some thoughts on this.
It depends. If you are using an Ohm meter you are measuring the actual resistance only.
To measure the combined Xl and Xc you need an impedance bridge.
Or the individual reactance values can be determined mathematically or with the help of a Smith chart.
The resistance does not affect the values of reactances.
And the reactances do not affect the value of the resistances.
Though the resistor can affect certain properties of the combined reactances, by damping the oscillation of the LC circuit. But all of the individual values are still there.
Here's how I like to look at it.
Think of mixing paint. If you want orange, you mix yellow and red. These are your reactances working together. How much of each will affect the hue of the orange you get. But the values of red and yellow you mixed in are still the same. Now if you add a little bit of black, (resistance) you get a darker orange but the hue is still the same, only the brightness has changed.
You can measure the combined brightness with a light meter, but you can not measure the hue or the individual color values without more specialized equipment.
