PRS Series PRS Speaker Cut View — Tweeter Smooth Off-Axis Response Soft-Dome Diaphragm The FEM (Finite Element Method) designed dome allows wide sound dispersion with flat & even response. SPEAKERS Sound Absorbing Material 25 cm (10") Component PRS Subwoofer Low Distortion Canceling Magnet ø255 178 Absorbs the back wave reflection from the moving tweeter diaphragm, preventing phase shifts or frequency cancellation-producing a smoother, more linear sound. Reinforces the magnetic flux density to provide greater control and precisely linear performance. Lower Crossover Frequency 28 mm Large Sized Diaphragm Main Magnet PCOCC®* Voice Coil Wire The purity of the copper in voice coil wire plays a significant role in sound quality, which is why the use of OFC (Oxygen-Free Copper) is a common practice. But for a Pioneer PRS speaker that isn't good enough. Pioneer features the world's-first use of the pure crystal casting process (PCOCC) in a voice coil wire. This "five nines" purity (99.9997%, compared to OFC's 99.99%) results in wires with superior conductivity, lower electrical resistance and reduced skin effect. * PCOCC is registered trademark of Furukawa Electric Co., Ltd. Back Chamber By utilizing a sealed rear cavity, low-end response of the tweeter is extended - allowing for a smoother transition infrequencies between tweeter and midrange. OFC Short Ring Focuses the magnetic field where it needs to be, increasing efficiency, lowering distortion and providing for more linear voice coil movement. rity 99.99% Pu Purity 99.9997% OFC PCOCC® • High sensitivity, unmatched linearity and superior speed designed to create the epitome of detailed, accurate and impactful bass reproduction. Key Selling Point PRS Speaker Cut View — Woofer High Linearity Sound Linear Moving Force System for ultra low distortion and high definition in bass sound. The high-density micro fiber material surrounding the woofer of a PRS speaker is very light and low internal loss characteristics. The Micro Fiber Surround realizes faster response and more accurate bass reproduction that allows all music to be heard to greatest advantage. TS-W252PRS Cut View Corrugated Surround Two different metals combine to reduce resonance. Micro Fiber Surround: Maximum Musical Response AL/Brass Dual Metal Center Plug Aramid Fiber (Conex) with Rubber Coating Sound Quality and Reliability Rigid and Light weight Cone and Cap structure realizes both reliability and high speed sound. OFC Short Ring Voice Coil with Short-Winding Length Short voice coil (underhung design) provides maximum control with very light weight, providing high sensitivity and superior musical detail. Progressive Flex Suspension System (PFSS) Focuses the magnetic field where it needs to be, increasing efficiency, lowering distortion and providing for more linear voice coil movement. Three layer design creates feather-weight cone with exceptional strength Aramid Fiber surface layer Foamed PP core Glass Fiber reinforcement layer 2nd Generation Multi-Layer IMX (Injection Molded Matrix) Cone 100 80 Most spiders are all brawn and no brains, but Pioneer's PFSS is a "smart spider" that adapts to your music dynamically. When listening to soft music, it delivers the detail and fast response required, but when the big crescendo hits, it provides the precise control as well as the long excursion required for exceptional sound quality.
