2:51 I know it wasn't intended, but the speaker should be tapped at 16 watts not 103 watts, he means that @16 wattage input the SPL at the desired location will be 103 dB.
I’ve got taps that say “8 ohms”, ‘N/C”, 40w, 20w, 10w and 5w. These are for 100V scale the values are halved for the 70V scale. What is the impact of moving the dial from the “8 ohms” position to one of the other spots? Will the speaker get louder? My Amp is 4 ohms 100W. Will it over-tax the Amp? I’d like the speaker to be a bit louder.
Low impedance and 100v line systems are not compatible with one another. You must leave your dial set out at 8ohms for the amplifier and the loudspeakers to perform correctly.
My local made pa amplifier output volts are 95v @ 8ohms. (450 watt @ 8 ohms) it has no output transformer. The dc supply rail is 95+95. Can i drive 100v line speakers on it? how many speakers i can drive on it?
Hi Gary - thank for the comment - understand what you're saying. For general users, we'll be producing an additional Blog on 70 / 100v tappings shortly which will give a simple how to guide; will send through the link when it's live. Keep up the great work!
he is just running around the bush...it is a tap i.e. a connection to get different wats from the same power line...helps you to fine-tune the volume of the end speakers...that's all...
The value of the calculations is knowing how to design a system and where to tap a loudspeaker to meet an accepted standard or specification. Tapping a loudspeaker is something that should be done once at installation and done correctly. If you are designing a system, calculations allow you to know what you need to purchase to make the system function. You cannot arbitrarily tap an arbitrarily large number of speakers and expect any amplifier to power them adequately. You may easily trial-and-error a few speakers, but if you are setting up a large system there is a need to involve some engineering.
I just want to tie the speaker cable to the speakers, plug the amp in and away you go. These guys are speaking a foreign language. I am in awe, but ignorant.

Great video, very well explained.
Bruh, can you just explain which direction to change the tap to make a speaker louder or quieter? That’s what i came to learn.
well done, thanks for this.
does the 70 voltline tapping divides the total wattage output of a speaker?

No you cannot drive 100v speakers from an 8 ohm output.
It can be very difficult to get a true understanding of what these tappings mean. So confusing for general viewers.
