Coaxial 2-Way Home Theater Speakers

WARNING - This is a big print! It requires a bed size of at least 20 cm x 25 cm. It prints great on a Prusa Mk3, but is too large for an Ender 3. These speakers are compact full range speakers designed for use in a small home theater. The coaxial design provides controlled off-axis dispersion to minimize sidewall reflections and maximize voice clarity. I am using them as the Left, Center, and Right channels in a Dolby Atmos 5.1.2 configuration. For surround and Atmos channels I designed a different set of speakers to match: https://www.thingiverse.com/thing:5365618 This speaker uses a Dayton Audio CX120-8 coaxial speaker driver in a small ported enclosure. The enclosure is made as small as possible such that it can be crossed over with a separate subwoofer at 100 Hz. The speaker has a low-cost first-order passive crossover network consisting of an inductor, a capacitor, and a resistor. Soldering and wiring skills are required for assembly.
