How many speakers can you connect to a tannoy s10
The question doesn't really make sense because a Tannoy S10 is a speaker. You can daisy chain as many speakers as you want. That's not the issue though. It's what load the amp sees that's the problem.
Most Hi-Fi speakers are a nominal (that means average) 6~8 Ohm load. However, the Impedance varies with frequency and phase. So at certain frequencies the amp will see a much higher load; maybe as much as 30 Ohms. At other points the load will drop to 3 or 4 ohms. The reason why your amp doesn't fry itself is that music contains a wide range of frequencies, so the load is made up of lots of different slices of impedance all summed together.
If you start to add extra speakers on to an amp then one of two things will happen. Either they'll be wired in series; in which case the Ohms load will increase by the addition of the speaker impedances e.g. 8 Ohm + 8 Ohm = 16 Ohms pre channel. Or the impedance will be reduced because the speakers are wired in parallel (1/8 + 1/8)inverse = 4 Ohms.
16 Ohms is about on the limit of what a very good Hi-Fi amp could drive. But the volume will be reduced and the amp will go into distortion much earlier.
4 Ohms is a much bigger problem. The impedance swings will dip dangerously low to the point where the amp sees the speaker load as a short across the terminals. At that point the amp will dump a whole load of current into the speakers, thus frying the voice coils and burning itself out. That ends with a small puff of smoke and a very large repair bill.
If you want a system louder then you have to add more amps and more speakers. Simply piling speakers on to an existing amp won't do it. You're spreading the amplifier power more thinly because of the extra load, so each speaker ends up being quieter.
