RE: 32 Ohm Drivers // 32 Ohm OPTs

Well, first off, I made a mistake, it is actually going to reduce power to 50%, not 25%. (I was for some reason thinking we were halving the voltage rAnd it may be a little more than 50% since the higher impedance load may allow the amplifier to put out a slightly higher voltage, but it won't be significantly more than 50%, and you are certainly better off with a matched load. After all, if the amplifier would benefit from, say, a 5000 ohm output transformer instead of a 2500 ohm one (the consequence of using double rated load), then it surely would have been designed that way.

Second, series parallel is better than just series, but not as good as just in parallel. Why?

Let's take four speakers, say the resonant frequencies are

1. 100 hz,
2. 105hz,
3. 101hz,
4. 103Hz.

If you put them all in series, speaker 2 will see more voltage than the other three at 105Hz, because it has its impedance peak at 105 Hz. In series parallel, this peak would be in parallel with another speaker, damping this peak, but not eliminating it, meaning that the other three would see more voltage than in a pure series connection, but still not the same as speaker 2.

If you put them all in parallel (ideal), then all speakers will see the same voltage at all frequencies.

If all four speakers are really identical, of course this will be less of an issue, but putting speakers in series is definitely not an ideal practice.

I don't think I have written this in a very easy to follow way, but hopefully I have got my point across.
