Hi,

could anyone give me some quick advice on how powerful amp I need to
buy. I am really getting confused with the whole rms/continuous two
channel thing. All these numbers are doing my swede in.

I bought two speakers from a car boot sale (swap meet) a while ago. On
the outside they say they are two horn 150 Watts.

On closer inspection they each contain two 10" speakers rated at 150W
RMS (8 Ohms) plus a couple of horny/tweeter type things with no rating
on.

But now I am confused. Is each speaker 150W RMS? or is it 2x150W=300W +
the tweeters. Or does it depend how the speakers are wired up?

The speakers only cost a tenner but I don't wanna blow them up. I have
been using them with a seventies home power amp rated at 600W but I
don't know if that is max,rms or continuous! Souned about right though
as long as I didn't turn it up full.

Can anyone give me any advice from this garbled confusion?

The calculation is actually not that hard. You take the date last Tuesday,
multiply it by your shoe size then add your age.

Unless these are branded speakers, from a manufacturer who is prepared to
stand by his claims, then that is about as useful as these numbers are.
What exactly are they?

In the meantime, don't turn them up past the point where they are still
sounding clean.

shoe size, thats a potential problem

Here's a simple answer...

In a perfect world, the speaker's power rating would be the power output of
the amplifier you could safely connect them to without much fear of damaging
the speaker.

In practice, I doubt this is the case. The speaker's power rating is
exaggerated.

So, what do you do? Simple...

You don't turn up the volume past the point where the speaker begins to
audibly distort. If that isn't loud enough for you, you need a bigger amp
(because you're clipping) or "bigger" speakers (because they can't handle
the power).

Your remark that the system "sounded about right, though, as long as I
didn't turn it up full" shows that you understand this.

Bugger! well, it works OK in England - just have to use the conversion
chart, I suppose.

From your description, I'd guess these are sound reinforcement speakers.
I'd guess that with one watt of power each, in a normal room your speakers
will sound about as loud as a symphony orchestra. With ten watts of power,
they will sound about as loud as a Deep Purple concert 40 feet from the
stage.

With one hundred watts of power, they will sound about as loud as the Deep
Purple concert ten feet from the stage, and you should be wearing earplugs
to protect your hearing..

Just how loud do you want to go?
