I'm new to all of this, but recently stumbled upon a Pioneer SX-790 that I intend to recap. The next phase is to build some speakers to complement this 45W receiver. I am currently considering building Statement Monitors and Troels Gravesen Classic 3-Ways. Does anyone have any ideas on proven designs that have an 8 ohm nominal impedance?
According to the owners & service manuals and the SX-790 will work with 8 ohm or 4 ohm systems. I understand Curt's comments on the Statement Monitor cross-over design that he calls it a 4 ohm design, but it is nominally a 6 ohm design. It appears that one advantage of using 8 ohm speakers is that the power meters can be used to view the power output to the speakers. I would also like to keep the nominal impedance at 8 ohms so as not to stress the amp. I would also prefer reasonably priced drivers available in the US.
This system will be used almost exclusively for music at moderate listening levels. The living room we'll put it in is approximately 12' X 25'.
Thanks in advance for any thoughts you have!

Check out the pioneer forum on audiokarma.org. I didn't know the power meters only worked with 8 ohm speakers? My sx-1280 power meters work with various loads. I personally prefer 8 ohm speakers on these old amps less stress I reckon
Hi,
Power meters typically work on output voltage only, or more rarely
they incorporate output current too. Sadly nearly all of them are
hopeless as they are faced with a near hopeless task of doing
anything accurately for the observance of a home consumer.
To make them interesting all sorts of shenanigans are employed
which render whatever reading they have to be near meaningless.
(Unless you understand exactly what the meters are reading.)
They are eye candy for the most part. Peak hold are probably
the most useful, but don't represent output power in any sense.
I'd forget about the meters in choosing your speakers.

Though in reality the Pioneer isn't exactly what you'd
call a powerhouse, and is IMO not remotely the sort
of thing you'd really need for the Statements.
Bang for buck and looking expensive when they are not
and absolutely fine for moderate levels build these IMO :

Headbanging they won't do, they will do great bass
at moderate volumes, compared to other options.
rgds, sreten.
Nice looking piece of vintage kit, sadly the internals are not as impressive.
Typically 4 ohm output was the same as 8 ohm, so go 8 ohm.

An externally hosted image should be here but it was not working when we last tested it.
