Dynaudio C1 II owners - how loud can you go?


Hi All,

I just had a question regarding the review of the Dynaudio C1 II's here: http://www.tonepublications.com/review/dynaudio-confidence-c1-ii/

Jeff mentioned that with the right amount of power, the speakers never run out of headroom. I bought a pair last year and connected them them to a Peachtree Nova220SE (class D - yes, but it's rated 350w at 4ohms). I download and stream a lot of digital music off my mac with itunes+amarra or via tidal, and this amp made sense - I listen to this setup in my bedroom and don't have a lot of room for separates.

My question for the forum is, do these have a problem when playing loud? I can't seem to get more than 10-11 o'clock on the volume control on the peachtree with bass heavy tracks before I hear a high pitched "pop" (almost a bird like "tweet") and have to lower the volume. Does anyone else have this problem? If so, were you able to correct the problem by swapping amps, cables, etc? Am I just expecting too much from these speakers?

Thanks,
Derek

Considering the scenario of heavy bass, loud volume, and a "pop", I'm thinking "bottoming out" of a woofer in one of the speakers. This occurs when there is extreme excursion of the woofer cone, and the voice coil hits the back of the pole structure. If this is the problem, you have reached the limit of the speaker's performance for bass reproduction, and a different amp will not solve the problem. The solution would be to add a subwoofer with high pass to the main speaker, or use a different speaker.
