The S4-C80 is the larger, more powerful sibling in Dynaudio’s Custom Studio ceiling speaker lineup — designed to bring high-fidelity sound to bigger spaces without sacrificing subtlety or style. With a larger 20cm MSP mid/bass driver and the same exceptional 28mm soft-dome tweeter found in the smaller S4-C65, this speaker delivers deep, impactful bass and refined treble ideal for home theaters, multi-room audio, or high-performance listening rooms.
The 28mm tweeter is tiltable, allowing you to direct high frequencies exactly where you want them. Meanwhile, the speaker itself can rotate 360° for maximum placement flexibility during installation.
