ATC SCM 40 vs. ATC SCM 50

Has anyone compared these two models?
I've heard SCM40 and I've been imporessed! So I'm interested in the bigger ones because they are in my budget for spekers. They cost much more and they are from the Tower series which is the highest line of ATC spekers so they must be even better than the wonderful SCM40.
Any opinions? :)

Anyone compared the current spec. ATC SCM40A vs the ATC SCM50ASL Classic ? On paper pretty similar, not sure that is the case on a side by side comparison.

Cost no object, ATC SCM 50 is the choice. This is because SCM 50 uses the audio grade dome midrange (part number SM75-150s) while SCM 40 uses the public address grade dome midrange (part number SM75-150). That's explained the difference in price and sound quality.

The SM75-150 used in the SCM40 has a less powerful magnet system than the 'S' version used in the bigger classic/tower and pro series monitors. This would mean less efficiency and output capability, but I doubt SQ has been seriously compromised since that isn't the ATC way. More likely the lower efficiency mid dome was appropriate for the lower efficiency sealed '40.

I think the fact that SQ is pretty consistent across models is evidence of this lack of compromise.

The Wilmslow kits were really not the  same as SCM 50 or 100 ,I understand the midrange crossover was quite different and not very well done.Regardless of that  ATC no longer sell the sell the drivers to anyone.Wilmslow now use Volt drivers.
