Sweet Room

[ThomasD]

I have tried SAM but did not like the result. Impressive first but not in the long run.

Hi, that is rather strange. I know many say they do not like SAM very much, but with Sweet Room SAM could really do wonders. This would be very similar to what I did: SAM on at 92%  - measurement with AudiolenseXO (not 100% SAM as this would trigger excursion limitation on the sweep). Audiolense would fix the ugly peaks in the bass region and it would all sound fabulous.
My theory is that SAM would make any resonances/standing waves in the room even worse. When corrected with Audiolense I really got to hear what SAM could do. I'm not saying your Dynaudios will benefit in the same way, but it might be worth a new try now that Sweet Room is here.

EDIT: I don't see the C1 ll in the list, only C1 and C1 Signature. Are you sure you are using the correct SAM profile?

Thanks for interesting comment. I use C1 signature which should be same as C1/II but maybe Signature profile is not optimal? I assume Dynaudio knew what they did when designing the C1. The profile tries to extend frequency range in the bass but my feeling is this has a negative impact on overall sound. The frequency range without SAM is within +-2.5% down to 30 -20000Hz.  This is enough for me and believe you can not ask for more from such a small speaker, or?
