Speaker Choice
Nothing to do with cars
I have been given a surround sound amp, but with no speakers
It is rated at 15W each for 5 speakers and 50W for a sub woofer, impedance is 4-16 ohms
What would be the best choice of speaker rating for this system?
Should I go for speakers rated higher than the amp can supply or stick to 15W? or any other things I should take into account?
Thanks

15W rating implies a low end unit??
Anyway, any speakers rated at 15w or more will be fine. Me, we use JBL control 1's all round, small, capable and not a fortune. Pretty
indestructible too (as in had a pair smoking, literally, at a pub gig many years ago, they survived intact)
Try richer sounds, always something of a bargain to be had there. Speaker packages a good way to go, and if funds tight skimp on the rear speakers,
they are effect only. Centre speaker very important.

Peak or RMS power?
It's the square waving of an overloaded amp that kills speakers, so don't get too hung up about the numbers matching, the speakers can be
less power than the amp and still be more than loud enough for the room.
DO NOT PUT ON KNOB OR BOLLOCKS!

Thanks, I know you can't just go by the watts as being an indication of potential volume as I have had 5W speakers in cars in the past that were
very loud
Not sure if it's peak power or just what they recommend for normal use
I was thinking that getting some speakers rated at 20 watts would mean they should happily take 15 watts for hours on end? If I got 100 watt speakers
then they would be hardly moving at 15 watts and so would be not as loud as a 20 watt speaker, is that how it works??
It's actually quite a nice quality unit despite not being 1000 watts etc and is for a quiet room and not a outdoor event ![](/images//smilies/bigsmile.gif)

No, it's more to do with a speakers sensitivity than power handling, and generally it's the sensitivity that you pay for, peak power and
frequency responses are usually just marketing headlines.
Five channels of 15 watts of RMS power would be very loud in a normal living room.
As for which speakers? Some that the wife likes the look of...
