[QUOTE="Ivan Beaver, post: 139378, member: 30"] Re: 60 Degree DIY Mid Hi Xmax is NOT the maximum travel a cone can have. It can have different meanings (derived different ways). Sometimes it is calculated-other times it is measured in the form of distortion. Basically what it means is NOT the maximum travel-but the maximum travel while staying clean and linear. OF course many PA systems are operated well beyond "linear". But in "normal usage" a cone can move quite a bit more than the rated "xmax". When the cone hits the wood-you get a real loud "crack" or snapping sound. You might want to consider clearances closer to "xdamage" to ensure good clearance. [/QUOTE]
