No one has ever stated the S40 was a perfect speaker, or couldn't be improved. Don't put words in people's mouths to promote an agenda that doesn't exist. The argument is that his specific "upgrades" would absolutely introduce other issues. Phase issues being one of them (the main one IMO). The largest change he made was the change in crossover point and slope. If you understood crossover design, you would realize that can be done extremely cheap. If Dynaudio thought a 1,400hz crossover point, and a 12db slope on the tweeter was a better option, they would have done it. The quality of the parts is a separate issue. If you don't have the knowledge to question his "upgrades", how can you make the claim we are "cultish"?I’m split on the S40, personally I love the speaker 90% of the time but it’s not great or even good off axis and there are other issues with it and I’ve lived with it for two years. Someone recently said it’s not a perfect speaker but it is a magical speaker and I’ll definitely second that. That said to think it can’t be improved upon is just silly, Otto has said many times with anniversary edition speakers they take certain liberties with the design, while they do some things great there may be some things left on the table. For instance the box does have some unwanted resonances but I with the port chuffing was also addressed, perhaps that was more than difficult based on the physical dimensions of the box. Anyway, maybe I’ll contact ASR and GR Research to see if the three of us are willing to to do some testing. Lastly I’ll say the knee jerk aversion to peer review is in my opinion unhealthy to audio hi fi and furthermore any discipline in general, some of the responses here are almost cultish.
Let's not forget that you are driving the S40's with a low level receiver. Until you upgrade the rest of your system, I highly doubt any opinion you give here will be taken seriously. Enough said.
