2 pairs of speakers are 8ohms ? and 1 pair is 6 ohms. One of the pair are
Wharfdale diamond III 100 Watts, maybe a little too powerful.

Many thanks...Nigel

Hi
I have just bought a new mini Hi-Fi, nothing special just a Sony
MHC-RG220(£130). I have the speakers supplied with the new unit(120w I
think) the cable for these is too short, do I just extend it? I have 2
other
pairs of speakers, can I use these instead? if they sound better. Does
the
resistance need to match the Hi-Fi, or something?
Any tips on learning more about Hi-Fi and televisions, as I have just
started working for a repair company.
Many thanks...Nigel



Nigel, forget all this 'Watts' rubbish with speakers - it's just a supposed
'maximum power handling' rating and totally misleading anyway. The
difference between 6 and 8 ohm impedance is not significant (in 90% of
applications in any case) and will only affect the maximum loudness to a
small, insignificant, degree. Just try all your different speakers and use
the ones that sound best. I would take the claimed 2 x 80W RMS (??) power
figures with a (big) pinch of salt but just use your loaf - don't run them
into distortion (amplifier clipping) and all should be fine.

Agreed. My Denon UDM-30 is 'only' rated at 20w, and rarely goes above 1/2
volume. It's much louder than some '200w' systems I've heard.

For the wire, just buy a few meters of 79 stand wire and ignore the brands.
It should cost no more than 80p/meter. If the wires are moulded to the
speakers you can get resonable results from just twisting the old wires
around some extra stuff and wraping it in duct tape. But if you want a
strong joint that won't degrade with time you'll have to solder them
together.

You can use a little plastic signal block. Ask at maplins and they'll
point you in the right direction. Different resistance speakers won't
damage the amp or speakers, it just might not sound as loud as it could.
