[QUOTE="Hennie, post: 33773, member: 20"] He uses whatever overlap is available from the design - and does not try to extend it to the lowest frequencies. The idea is to cover as much as possible of the modal region, and thereby to have as many LF sources as possible in that region. In big rooms his mains won't reach the primary mode though, as their low extension is limited. Hell no. There are enough measurements to prove that his method works. There's no argument about that. There are other methods with different trade-offs though. Mains overlap will probably not be helpful w.r.t. Harman's .25 / .75 plane wave emulation method, or the DBA, or Kreskovsky's method. Or Welti's latest thinking. But mains overlap is helpful w.r.t. Geddes' distributed LF source approach. So nobody is right or wrong. The approaches and their trade-offs differ. Yes, most likely, as said, there are trade-offs with all these methods. And this is one of them. Geddes' method can only be used with mains that are robust against overload. Vaughn, let's just accept that there are various methods each with unique trade-offs and conclude these arguments. Other people might be interested in discussing the other aspects of bass management, and you seem to be clued up on that. [/QUOTE]
