Hello jw if box rise is influenced whatsoever by the number of amplifiers used in a system set up or if it is essentially the same regardless of how many amplifiers are used to power a set of drivers

no difference.

Also, if you add more power without adding more batteries, your rise will go up.

current and voltage in influences voltage\current out.

There is no such thing as box rise. However there is an impedance CURVE, so depending on the box and frequency being played it is possible for your impedance to drop or ride.

Terminology doesn't make it non existent.

Most people know it as box rise for those not being technical.

And electrical system plays a LARGE role in it's effects to.  

For those who compete, it's easily measurable.

That's why in some classes in competition, it's better to remove some batteries in the install to prevent the amplifiers from running at such a low impedance.

Your impedance "curve" alters what each frequency in the playable spectrum will be but if a user measures that, that information can greatly be changed\altered by upgrading\downgrading your electrical system... Whatever the purpose is.

And most of those most use it as a reason to think they can put more load on their amplifier and not burn it up. Education is amazingly helpful in life.

This is why i am trying to get people to stop running below 1 ohm impedance on 1 ohm stable amplifiers.  

That's a whole other topic though but i do not disregard education.  I actually have charts of other amplifiers characteristics on how they should perform based on impedance during play.

But the main thing is i believe 99% that people will not stop playing below 1ohm for the simple fact the korean\chinese buildhouses keep tailoring their designs to the brand owners request which basically is-  Make it .5 or .25ohm stable where the base model is only 1ohm stable.

We know of one company who tried that and failed bad- CT Sounds.

Other companies pay out even more money to keep them stable below 1ohm but instead of these companies playing hide and seek with their Abusive Specifications, there should be a standard..  
1ohm stable means 1ohm stable, nothing less but i doubt that will ever come.

Care to post the charts up?  I would definitely appreciate a view! 

It wasn't a reference that actually pertained to this topic, just rambling about something going off topic.  The chart is for a very specific line of amplifiers that has no relevance in this topic.

.17 ftw!
