[QUOTE="Ivan Beaver, post: 89501, member: 30"] Re: Maximum analog snake length And once again-what the "theory" says 9or what people "think" it means) and what reality is are often VERY different things. Yes you will get HF rolloff-so many people just "assume" that it is a bad thing-and they never look a little bit further to see if it even matters! If you can hear 3dB rolloff at 22K through any normal PA speaker (or any speaker for that matter) you have MUCH better hearing than me. Yes it is happening-but I DON'T care. Just like in speakers-A product may claim a 40° pattern, but the horn opening is only 8". So that means that the "40°" pattern can only be down to 3KHz or so. Below that is wider. So do they REALLY think that having a rotatable horn is REALLY going to make that much of a difference? Only in the upper octaves-but down in the "meat" of the sound-NOTHING is going to change-yet people will talk about it all the time-"OH just rotate the horn so the cabinets will couple better" YEAH RIGHT! Have they EVER ACTUALLY LISTENED to it? or do they just "get part of it" and "think" that it carries all the way through------------------------ Sounds like a "good idea" except it DOESN'T work! Or it only works jsut a little bit-but then if you consider how far apart the drivers are-and all the combfiltering that is going on-how much of a difference did it REALLY make? What about the coverage of THE REST of the speaker system? It doesn't change when you "rotate the horn". Just like skin effect on cables-SURE it has a VERY REAL effect and is easily measured BUT NOT AT AUDIO FREQ!!!!!!!!!!!!!!!!!!!!!!!!!!! So why bother if it does not make a difference in what you hear? Or Damping factor- How any people (not you JR :) ) have ACTUALLY done the MATH on their SYSTEM in regards to damping factor? If they would, they should quickly realize that the damping factor of the amp is completely washed out by that of the rest of the system-cable-connectors etc. So yes damping factor matters-but NOT in the amp!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! At least for most cases in "normal" system. Sorry to rant-but there needs to be a lot more "Audio 101" being taught and NOT about "the cool plugins" on a console. We are missing THE BASICS so much these days. The FUNDAMENTALS are VERY important-if you want to have a REAL understanding on what is going on. [/QUOTE]
