Hello

I would need the specs of the Celestion Ditton 15, like the nominal power
and the efficiency, etc...

Anybody have them ?

Thank

Gaetan

I replied with the power handling to your AA post.

Hello

Yes I did ask it in few places since there is quite nothing about Ditton 15
specs in all my Google seach.

Nominal handling capacity was 15 w, impedance 4-8 ohms. Sadly my references
don't give any figures for efficiency, but I recall it was low, at a guess,
80-83dB ref 2.83 volts.

From http://www.audiokarma.org/forums/arc...p/t-8894.html:

"The Ditton 15 was very popular in the mid70's in the UK, Oz and not
sure where else. Specs are :

Suggested amp rating 10-30 watts
Freq response 30 hz to 15 KHz.
Sensitivity 4.2 Pink noise W at 1M 90Db - whatever that means "

If this is reliable [1] the sensitivity was about 84 dB SPL at 1 metre
for 1 W (actual/nominal?).

[1] There's no real evidence but the 15 kHz is about right for a speaker
using a HF1300 and no super tweeter as they did in the Ditton 15s
(but not the 15XRs IIRC).

** Bad maths.

4.2 volts is 3.4 dB more than a nominal 8 ohm watt ( ie 2.83 volts)

So, the maker's rated 1 watt sensitivity is 86.6 dB SPL.
