Question about Audio & Video Receivers
Yes! The speaker outputs will have an impedance rating from 4Ʊ to 16Ʊ. If you have two speakers that are rated at 8Ʊ they can be wired in parallel for 4Ʊ total or in series for 16Ʊ total. You can even connect more speakers in a series-parallel circuit, say four to result in a sum of 8Ʊ, 16 speakers to result in 8Ʊ and so forth! Study Ohm's Law and you will see how the circuit looks. Series connection for example will have the + lead from one speaker to the - lead of the next then the + of that speaker back to the - of the first speaker. Parallel is just that + to + and - to -. Series parallel is just a combination of the two circuits. If you have a several speakers of the same size within a single cabinet that are all in phase it is like one giant speaker as it is the air moved that makes the sound. Bose speakers phased-arrays use a sophicated application of this principal to get awesome bass with less distortion than one big woofer. Do not go under or over the impedance rating or the amp could suffer. Fusing can help.
