With Tesla-level magnetic coil technology and a bilateral four-unit design, it delivers remarkable analytical precision and a wide dynamic sound field. The 6mm micro coil handles high and ultra-high frequencies, while the 10mm large dynamic coil excels in mid to low frequencies. With a combination of N50 and N50 magnets, the STA series achieves a magnetic flux of approximately 10,000GS, offering a powerful and energetic audio experience.                                                                                    Precision Engineering for Unmatched Sound Performance                        The STA Pro features a 10mm and 6mm dual polymer composite diaphragm, delivering sharp dynamics and rich detail with a smooth, balanced frequency range. It undergoes hundreds of simulation experiments for optimized acoustic performance.The STA Pro Ultra combines a 10mm nano ultra-thin graphene diaphragm and a 6mm polymer composite diaphragm, offering powerful dynamics and musical detail. The graphene diaphragm’s elastic modulus is approximately 100 GPa, ensuring ultra-fast response.The STA Pro MAX uses a 10mm liquid crystal polymer (LCP) diaphragm with a 6mm polymer composite diaphragm, delivering a durable sound with rich musical charm. The LCP diaphragm’s elastic modulus is around 100 GPa.                                                                                    High-End Audio Performance for Exceptional Listening                        The STA series boasts a high-end audio-grade target frequency response curve, delivering an ultra-wideband loud field with a range from 10Hz to 30,000Hz. This balanced frequency response enhances the music appreciation experience by revealing richer sound details, making it easy to distinguish ","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/STA-ProSKU.jpg?v=1740733809","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/STA-ProUltraSKU.jpg?v=1740733809","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/STA-ProMAXSKU.jpg?v=1740733809"],"price":49.9,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.264Z"},"share_url":"https://firestarter.network/l/lst_BS22LkY_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
