Hi Richard,

Never one to refuse a challenge.
The old speakers were a pair of Celestion Ditton 15XR's with 30 watt per
channel rating and a flat sound response output from around 20Hz to 20kHz,
104db at 1 yard driven with 1 watt. The XR stood for extended range
indicating that the speaker design had been modified and upgraded from the
original Ditton 15 specifications.


Hi Mike,

Pretty impressive. My own Pioneers fall 10dB below that.

The new speakers I mentioned are a pair of Creative T20's. 14 watts per
channel from a built in amp and very nice to listen to.


Good to have a recommendation there too.

They don't really
compare with the Celestions for the smooth mellow sound that only seems to
come with wooden cabinets, but for the price they are excellent. Good point
about the magnets though. The super high powered magnets, ultra rigid,
lightweight fibre glass cones and developments in ported cabinet design have
all contributed to the superb performance of the T20's.

Apparently they have been out for a while now, but it was only when I was
wandering about in a PC World store that I heard a pair up and running. I
was stopped in my tracks by the sound coming out of these tiny devices and
spent a good couple of minutes looking for the subwoofer unit that I felt
sure was hidden away somewhere. There wasn't a subwoofer and after that, I
just knew I had to buy a pair.


I would have to agree.

I have no connection with Creative and in fact I am a bit annoyed with the
company's attitude to (not) providing proper sound card drivers for Windows
Vista.


Maybe with service pack 4.

Anyway, just go and check out the web reviews.


I will.

Sorry everyone else, but this bit hasn't really got anything at all to do
with antennas.


But it does show how performance correlates to numbers to theory to
practice - something dreadfully missing in Art's contributions, if you
can call throwing claims against the wall to see what sticks as a
contribution.
