Not to argue with anyone, but as a vendor I need to design stuff to fullfill the requirements of my customers. Some of their requirements may be silly, but if it is easy to verify by means of measurements, then I'm stuck with the requirement. If I am good at it, it brings me advantages against my competiters. If my customers require sub 100 ps jitter on their AES/EBU connections, then I need to deliver. As for speaker cables, for most cases normal 2,5 mm² is more than enought. Skin-effect on speaker cables is big-time bogus. Arguing about stuff like that while having ported boxes and passive cross-overs shows that one hasn't understood basics. The HiFi-world is FULL of stupid things. We didn't do any of that when I was designing professional PA-riggs. Current-driven speakers is surely better, but does not solve all the issues about speakers. There is loads of issues to speaker element adaptation to the air, which is a non-trivial issue. Ah well... When it comes to stuff like audio, there is no objective truth. That's probably the only objective truth you'd ever get. There is however many usefull partial analyses. The air is inherently non-linear, the ear is inherently non-linear. The world of audio is inherently limited to approximations and the mind is easy to suggest things, such as something is better or worse. The 3-dimensional wave as it spreads over time, reflects and interacts with the surrounding, with the impulse-response rather than frequency response problems and potentially very high dynamic makes the field uhm... complex. The field of time and frequency feels so relaxingly simple in comparision. :) Cheers, Magnus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
