JPEG Images of the Speaker

These images were taken on 35 mm film and processed by Seattle Film Works where they were converted to lossy compressed digital images. They were subsequently converted to JPEG. The resulting images are good, but color accuracy is suspect following two levels of compression.

• Completed speaker; 28,837 bytes
• Completed speaker without grill; 33,163 bytes
• Crossover in top chamber with top removed; 29,696 bytes

Here are some higher quality images with more accurate colors. These were scanned at 75 dpi in TrueColor, cropped and gamma corrected before compressing to JPEG

• Completed speaker; 37,357 byte
• Completed speaker without grill, 47,546 bytes

LEAP Schematic and Predicted Curves

• Schematic of crossover; 13,165 bytes
• LEAP predicted individual frequency response curve; 20,822 bytes
• LEAP predicted overall frequency response curve; 19,894 bytes
• LEAP predicted phase and impedance response curves; 16,557 bytes

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 !
