ATC SCM40A speakers

I've had my ATC SCM40s(V2 Passive) for around 18 months. I first had them driven by Marantz Model 30, then by a Heaven 11 Billie Mkii. 

Recently I've added an Atoll AM200 power amp (120w) and use the Billie as pre-amp. I guess the bass produced is partly room dependent, but in a modestly sized room like mine which is partly treated, I've stopped using my sub as there's no need. Acoustic bass/double bass is wonderfully reproduced, to the point you can feel it in your gut but with no bloat.

Since I've added tubes by way of the Billie, especially now in pre-amp mode, and the gutsy Atoll power amp (dual-mono), which really takes control of the ATCs, for me this is a match made in heaven (excuse the pun 😊)

A few days ago I came to the realization the only complaint I have with my 803 D3s was a somewhat strident treble. 

So I did the stupidly simple task of reducing toe-in of about 30* to zero (speakers are aimed straight ahead).

Viola! Treble glare gone! Now sounds coherent from bottom to top.

To me, sounds wonderful. Happy camper. Think I'll keep em.

Thanks to all who have contributed to this thread.

Boom!

The post above is a reat example of how speakers (really most drivers) sound different off axis.  This is almsot a universal, but there are some drivers that are better than others.   Since this is a post about SCM40A, the mid dome driver and the new HF dome driver are specifically designed to sound nearly the same on and off axis - to a point.  Nothing is perfect. 

Some of the driver designs you think would be better are actually worse!
