Il y a une revue intéressante des 52SE sur le site audioholics:
http://www.audioholics.com/productreviews/loudspeakers/dynaudio52sep1.php
Pour résumer, le reviewer a apprécié l'excellente extension des basses et leur fidelité, les aigues ouverts, la belle scène sonore, la "facilité d'amplification" (voir la
courbe d'impédance; elle descend jusqu'à 5 ohms, mais globalement tourne autour de 8 ohms, à se demander pourquoi Dynaudio annonce 4 ohms).
Par contre, il a regretté les médiums dans la moyenne de ce que rendent d'autres enceintes de cette gamme, et
un woofer qui talonne lors d'écoutes à haut niveau sonore d'enregistrement comportant des basses velues.
Pour citer le passage qui concerne ce talonage:
Just when I was about to declare the Dynaudio Audience 52-SE's the definitive bass master of bookshelf speakers, I was thrown a curve ball. Fourplay's -Between the Sheets title track "Chant" is not for the wimpy speakers at heart. In fact, Fourplay should add a disclaimer to this CD - "We don't warranty against blown woofers, listen with care". I was eager to hear the bass response of this song on the Dyne's and fired it up. Instead I heard a shockingly loud popping sound predominantly out of the right speaker each time the bass drum hit at the song's intro. Thinking there must be a defect in the woofers voice coil assembly, I immediately turned the music down, disconnected the right speaker and re-listened with just the left one. The popping sound surfaced again, but I had to inch the volume up just a tad for it to be as loud as it was heard on the right speaker. What I was hearing was the woofer bottoming out. I was astonished to hear this in a modern day speaker, especially since most drivers now employee a shorting ring on the bottom of the pole piece to prevent the voice coil from going out of the gap.
My recommendation here is either to use the volume control sparingly during bass-intense music listening sessions, or cross them over between 60 - 80 Hz or so, and supplement them with a subwoofer.
[...]
I was a bit perplexed by a few inherent design anomalies such as the lack of recessing the woofer into the baffle and lack of countermeasures to ensure no woofer bottoming. Perhaps a different bass alignment would be more appropriate in this design.
Vu le message de cheam ci-dessus, est-ce que Dynaudio aurait corrigé le problème sur le woofer des 52SE ?
