Default Xmax Question

When speakers list there xmax as say for example 6mm, does this mean its excursion is 6mm either way from center.

i.e. its excursion is 12mm from both extremes.

It depends whether they are lying or not, should be one way, often bothway.

Yes - I don't think manufacturers are consistent about this - you should try to contact the manufacturer to specify halfway from center or total cone travel - hopefully they will tell you.

manufacturers see this ...

If its peak to peak you often see the addition (p-p), and even (+/-) if its one way...but not always I think like linearray that Xmax without further specs is one way, or should be
sometimes we know very little, and sometimes we know too much

... if you are eager to learn something about linear excursion contact W. Klippels homepage. There is a lot of stuff about it


After reading you can decide if manufacturers are lying or not


PS: Next version of STEPS from ARTA-family will content a Klippel module for measuring Xlin. Have a look on the ARTA Homepage at the end of the week:
