I've just discovered that my Monitor Gold 15" drivers are fitted with a mismatched pair of HF units.
One driver sounds slightly brighter and more forward that the other and I'd like to make them as near perfectly sonically matched as a pair as possible.
The fact that they have different HF units wold seem to be the likely cause of the slight sonic mismatch. The other possibility is that the alignment of the HF diaphragm is out on one unit.
Anyway, first things first and I want to confidently identify what the HF currently fitted are. I've already spoken to our resident guru Frank (who has been hugely helpful and generous with his time as ever) and he thinks that the 'crinkle' finish unit is the correct/original 205 and that the plastic/Bakelite unit may possibly be a 105 unit from a later K series driver.
Here they are:
This is the one we believe to be an original '205' type and is the unit which sounds slightly more 'recessed'.
