Polk Audio - Signature S30 - Centre Speaker Walnut
Built to bring the big surround sound theatre and music experience into the comfort of your living room, the Polk Audio S30 Signature Series Center Brown continues in the Polk tradition of American HiFi. Whether upgrading your home theatre setup with an advanced Atmos configuration or enjoying music, Dynamic Balance ensures a rich, clean, full-range sound no matter what you’re listening to. This patented technology analyzes the speaker’s entire electro-acoustic and mechanical system for improved material selection and more efficient geometry. Our newly designed Terylene dome tweeter features curvilinear formers that extend response and lower resonance. Its powerful ceramic motor structure also lowers system resonance and extend low-frequency response for better dispersion in the critical midrange, delivering clear and detailed high-frequency response for realistic reproduction of vocals and instruments. Certified and capable of delivering 40kHz to support the latest high-resolution audio files so it feels like you’re right there in the studio or concert hall. Power Port® is our patented design that smoothly transitions the airflow from the speaker’s port into your listening area. It also extends the overall bass port, providing a greater surface area to eliminate turbulence and distortion, for bigger, more musical, deep bass impact. Plus, it offers 3dB more bass response output than a traditional port. Featuring Hi-Res certification, a new Dynamic Balance designed acoustic array, precision cross-overs, an anti-diffraction grille, modern cabinet styling and exclusive Power Port bass enhancing technology, you get elevated sound for movies, TV and music in a totally re-imagined design. Crafted to suit all your audio needs, the Signature Series will fit into your home and deliver great sound for years to come.
