In this design, the powerful magnetic poles are positioned on both sides of the sound membrane, resulting in a centripetal convergence that directly drives the sound unit. As a result, the radial magnetic field becomes more uniform and stronger, leading to improved sound density and off-axis response. Additionally, this technology eliminates any magnetic loss, resulting in higher magnet efficiency and increased sensitivity with minimal distortion.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003eAfter years of development, we are pleased to introduce the High Sensitivity Dual Air Motion Super Tweeter-HST. The AMT driver measures 5 x 1 inches (128mm x 25mm) in size. The Kapton has a thickness of 12.5 μm, while the Aluminum is 20 μm, resulting in a total thickness of 45 μm. Sensitivity testing was conducted using 2.83v @ 1 meter. The crossover utilized is Butterworth. The components include FR4 pcb board and Aperion custom capacitors. High purity copper internal cables are used to minimize resistance. The transducer features a single ribbon design with dual firing open baffle, ensuring even distribution of the driving force across the vibrating element.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003ch2\u003e\u003cspan style=\"color: #990000;\"\u003eSpecification\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable style=\"height: 358px;
