is a Devialet 120 sufficient fir driving Sonus Faber Cremona Auditors M speakers?

[Jwg1749]

I have just discovered that in my system Auditor M sounds much better (with SAM on) when I wind the rear cones fully down to achieve the correct tonal balance and proper weight. When I tilted them back too far, they started to harden and shout, losing their great bottom-end foundation and superb hightones.

Do you mean that you're adjusting the height of the spikes on the base? Apologies if I've misunderstood.

Hi
I wind ONLY the rear cones fully down! Only REAR. Front cones are in factory/original setting. Thanks of it speakers are nearly 100% in vertical position, not as in FACTORY/original setting when they are bended.
In my room and system when I bended them (as in factory/original setting), they started to harden and shout, losing their great bottom-end foundation and superb hightones.

Thanks, I understand now. I'll give this a try.
