Crafted to rival the industry's leading offerings, the Crimson stands as a compelling product bearing the Symphonium label.

The Next Standard

The Crimson sounds bold and captivating, reminiscent of high-end speaker configurations. Endowed with a larger bass signature, it retains impeccable control and texture on the low end.
Soundstage is wide mimicking the experience of standing in front of a live stage. 
Vocals are natural and sweet, and detail retrieval is reference-level.

With the inclusion of PHAT technology, the Crimson is free from unecessary frequencey inversions or phase cancellations. The outcome is a treble that is not only smooth but also well extended. The combination of these characteristics makes the Crimson dynamically engaging and uniquely captivating to listen to.
