Horn Flare / Front Firing Exhausts design & fabrication for Altar Space

System Design and Tuning - Ohmi Cabinet Technical Fabrication - d duàn 段耀钦 Utilizing the drivers from Altar Space’s decommissioned spatial sound system, [+-]bloom reconfigures an existing system into an evolving ecosystem.

Two mirrored 160L sealed enclosures form a three-way, multiple-entry horn, with dual 15” woofers and a 1.4” compression driver. The front firing exhausts, designed in reference to JMOD’s multiple-entry horn, work to sum mid and low frequency drivers creating a single-point acoustic centre without the lobing or phase issues of spaced multi-way systems. Designed primarily for front-of-house use, each enclosure can be detached and redeployed as part of a larger system, mid-bass, mid-high or kick, depending on the configuration. An adaptive system which plans for redundancy.

[+-]bloom is an ongoing exploration of where the technical ends and the organic begins.
