Product at a Glance

The systems can be controlled using the Delta Control Software for a brief setup. The controllers offer multiple input & output EQ Filters, Routing, Peak Limiting, Compression Settings over a 96Hz sample rate


Painstakingly Perfect Production

Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
