Seriesing speakers?

If I were to replace one 8 ohm speaker 500 watt with two 4 ohm
speakers 300 watts each in series, how would this affect the quality
of the sound?

Thanks,
Dan

The reason I want this is on camping trips, my family and I
often enjoy playing music together. One brother is a loud
banjo player, another mandolin, a sister plays battery operated
keyboard. So my acoustic guitar doesn't have a chance
against these loud instruments. There is no 115 VAC available.

Speaker impedance isn't constant -- it varies widely with the
frequency and is dependant on the enclosure too. For two
identical speakers in identical enclosures, it should be OK.
For two different speakers with different impedance/frequency
graphs, they would each sound like they were being driven
through different graphics equalizers with the sliders set to
random positions.

You would get more predictable results with two 16 ohm speakers
in parallel. Then they wouldn't need to be identically matched.

In either case, the total sound output might be higher or lower.
That would depend on the efficiency of the two speakers verses
the original speaker. The output can become much more directional
though (Youngs Slits effect*) giving loud and quiet areas, which
in some cases (off-centre) will vary by frequency.

It would still be too damn loud.

Being in series, the electrical damping as seen by the LS
back into the amplifier would be very different, hence
the bass response would vary. Putting LS in series
is generally not a good idea. Glenn.

From an electrical standpoint there should be no trouble in doing what you
want. wire the + or red terminal of one speaker to the - or black on the
other. How it will sound depends on too many variables, many of them very
subjective, to discuss

FWIW the de-facto standard in guitar amplification is a series / parallel
combo of 4 16 ohm 12" speakers.

Yeah, but its designed to work like that in the given cabinet.

The LF damping on each speaker would be different if they
were all connected in parallel, or all in series, and then the LF
response would vary.

better qualified as "without considering the effect on damping".
