The speakers I designed and built myself. They are made out of MDF 4’x8’ 3/4” thick sheets. The cabs are made in two sections (bottom: woofer cab, top: mid and treble cab), so they’d be easier to move. And I veneered them with walnut hardwood veneer. The crossovers I designed for them are 2nd order Linkwitz–Riley circuits crossed over at 250Hz, 1.8kHz, and 5.6kHz. The drivers took a lot of research to find/choose. I chose them on brand and paired them in accordance with their frequency charts. The upper dome drivers are silk domes with neodymium magnet drivers, along with a special faceplate design to maximise their dispersion. The lower cone drivers are layered carbon fiber sandwich cones with massive ferrite drivers. Their frequency response is 17Hz to 22kHz and SPL is about 90dB at 1 watt 1 meter. I intend on installing fuses and PTC self resetting fuses, one set per section for protection. They each have a max output of about 4,000 watts, although I haven’t had a powerful enough amp to test that. I also added double binding posts. But their best quality is their soundscape, depth, center imaging, and throw. And they’re not quite finished yet either. There’s a few cosmetic things and some minor crossover adjustments to be made once I have a more suitable space for them. I’ve also built a few preceding pairs if you’d like to see. If you have any questions I would be happy to answer.
