Preface: I have an Onkyo cs-415 micro system in the bedroom which I got
for
usage as a wake-up alarm thru the use of its timers. the cs-415 system
has
a cs-315 receiver which produce 14 w @ 8 ohm & 19 w @ 4 ohm "ftc"; the
speakers are 4 ohms.

I've been using the system also to play webradio & am thinking of
replacing
the speakers with small Polk Audio speakers or something that would fit on
my bookcase headboard (max depth ~9.5 in); the speakers I seen have
impedences of 8 ohms & 20-100 watts are the recommended power to run
them. The speakers would be the Polk M10 or R150 or DCM small speakers.

Question: I remember that the Heathkit 15-20 watt amps were quite able to
power the lo-efficent Acoustic Research AR 2 to loud sounds.
Is
there any reason that the speaker mfg would recommend higher
power ratings than what was quite capable in the early days?
Are
current receivers/amps overblown in their pwr ratings? Are
they
of less quality than the old tube stuff?

I don't listen loudly as I'm in an apt the Onkyo isn't my main system
which I
have in the living room. Are speaker mfg just trying to be "safe" from
lawsuits?

Not less quality but different design objectives. Should still run your low
efficiency speakers in the bedroom scenario you describe. Continuous higher
volume would be a potential problem, mainly because the Onkyo has rather
small heat sinks.

    ... I have a 4 watt Lil Punch amp that I want to run through the cab. ... Looking at the two jacks on the back of the cab the RH one when used on its own will probably allow access to all 4 speakers at once, whereas when the LH one is used as well it will probably split the speakers into two pairs which can then be used with a stereo amp or with two leads into a single mono amp. ... If the overall impedance of the cab in 4x12 mono mode is 8 ohms, each individual speaker could be 8 ohms if each pair is wired in series to give a total of 16 ohms per pair and then the pairs being wired in parallel when in mono to arrive back at 8 ohms for all four speakers at once. ...
