Luv.Kem - a BiOdinsOrbs speaker

thingiverse

Luv.Kem's BiOdinsOrbs provide a truly exceptional listening experience. No matter where you sit, whether it's close to the speakers or far away, these speakers deliver an incredibly wide soundstage that feels eerily real. You can close your eyes and it's as if you're right in front of the artist performing live. These BiOdinsOrbs are also incredibly efficient, playing cleanly and loudly on very low power sources. In fact, on a modded Lepai 2020 with only 20 watts, they sound amazing. And when fed more power, such as from a NAD d3020 (30-65w), the volume can be turned up to un-listenable levels. One of the most impressive aspects of these speakers is their ability to prevent listening fatigue. From day one, I've been able to listen for hours without feeling tired or fatigued. This is something that many other speakers just can't match. The BiOdinsOrbs also roll off smoothly at the lowest end, making them a great option for those who don't have a subwoofer. However, most people will find that adding a subwoofer really enhances the audio experience. When it comes to balance and sound quality, these speakers are perfectly balanced between critical and relaxed listening modes. Poor recordings may be highlighted, but they remain enjoyable to listen to. For those who want to build their own BiOdinsOrbs without buying a custom-built set, there's a DIY option available. Here are the materials needed: Drivers: - Tang Band W4-1337SA midrange - Peerless/Tymphany/Vifa OT19NC00 2/3" Ring Radiator Tweeter - 4 ohm Bamboo: - Ikea Blanda Matt 11” Bowls Article # 501.111.43 Bonding: all glue surfaces have been sanded/scuffed to bare bamboo Titebond II was used on both surfaces for wood to wood Loctites PL 3X construction adhesive was used as a gap bridging reinforcement between the center spacer ring and bowls Automotive goop was used on wood to abs plastic Center Ring: I had MDF CNC rings made Via CustomMade via Mike Budd https://www.custommade.com/by/mbdesigns/ To do over, I would go with 1/8" bamboo ply laser cut by a shop such as Ponoko The Center Spacing ring is critical, and here's why: 1 – the speakers are not a true sphere. More like a sphere cut in half with the top 5mm stripped off and the bottom 10-30mm (bowl bottom) stripped off. It looks very odd without the spacer between. 2 - the grain direction of each layer of ply is different on the bowls. This allows them to rest into slightly different diameters/heights. The middle layer break helps to hide this imperfection from the eye. 3 - the bowls diameter is somewhat flexible. By using glue and tape to hold the bowl lip to the ring --- flexing the diameter to a consistent spacing on each of the 4 rings, it is really easy to get these bowls to more perfectly mate. 4 – the bowl halves are rather flexible. Adding the ring makes the bowl rock solid stable 5 - I placed 1 pound of roma plastilina #2 Clay softened with mineral oil in bottom of each enclosure. I rolled it flat and placed 1/2" pound rectangle in each bowl half to help with balance and dampening of the bamboo Misc Notes: * Tweeter Pod (ensure to chamfer inner edge by 1/64" to prevent the tweeter face from making contact *Mounting Ring with square nuts (0x10x3mm - 10-32 Menards part # 85611)
