Home Amplifier put somebody through the mill..?
Answers: If you know the impedance of the speakers, and also know the expertise of the amp with high regard to speaker impedances, you can use the additional speakers near the same amp. In command to do this, the following requirements need to be met:
1) The untried speakers should be nearly the same impedance as the existing ones (all 8-ohm or adjectives 16-ohm, for example). Small differences are ok (e.g. 6 and 8 ohm can be mixed, but not 4 and 8).
2) Connect the new speakers any in series or parallel beside the existing ones; which way depends on the amplifier impedance specification. Connecting the speakers surrounded by series adds the impedances: two 8-ohm speakers surrounded by series will give an impedance of 16 ohms. In parallel, the combined impedance will be partly of each if they are alike, so two 8-ohm speakers in parallel offer 4-ohms. Pick a combination that gives an impedance that the amplifier will switch (it will specify a range, resembling 4 - 16 ohms). A 6 and 8 in series give 14 ohms, but in parallel give 2.4 ohms (too low for most amps).
3) When connecting the speakers pay attention to the polarity;
Series nouns: Amp + output to speaker 1 + terminal, speaker 1 - terminal to speaker 2 + terminal, speaker 2 - terminal to amp - output.
Parallel connection Connect both speaker's + terminal together to the amp +, and both - terminals to amp -
The output volume may cash depending on the connection, but you can confidently adjust for that with the volume control.
Of course, if you are liable to add a unsullied amp, that will also work and in combination give you greater power output know-how.
you can buy a switch box, the switch box will give you further channels for you to plug more speakers into. (it connects to where on earth a set of speakers should be). However i don't recommend it as you will have smaller number power for each set of speakers you use. Buy a modern amp with more channel.
