LEAP Schematic and Predicted Curves

VRML 3D Model of the Speaker

Here is a VRML model of this speaker. This model is intended to provide a 3D view of the speaker in fairly correct proportions, including some internal details. It does not contain textures for realistic rendering; see jpegs images for actual looks. To see the internal components and chambers, view this model in wireframe mode (if your viewer lets you). The model will give you an idea of the various pieces involved and their relative placement but is in no way complete. For instance, the woofer and midrange are modeled as simple cones, and the tweeter is a flat circle. No braces are shown, and many MDF seams are abscent. The crossover is not modeled.

Note : some VRML browsers do not seem to correctly render this model !
