It is built for listeners assembling high-sensitivity systems where clear upper-frequency reproduction is needed alongside mid-bass drivers and subwoofers. With a 3,000 Hz to 22,000 Hz frequency response, it is intended to handle the upper range rather than full-range or bass duties.\u003c\/p\u003e\u003cp\u003ePart of Pioneer’s P.R.O. Series, the TS-B351PRO is suited to open-show and high-SPL-oriented installations. Its 100 dB sensitivity rating helps it produce substantial output from available amplifier power. The 4-ohm nominal impedance makes it suitable for use with compatible car-audio amplification and crossover arrangements.\u003c\/p\u003e\u003cp\u003eThe tweeter uses a titanium diaphragm in a horn-style bullet design. This combination is designed for direct, efficient high-frequency projection in systems that need to remain audible at elevated listening levels. Pioneer rates the pair at 150 watts nominal power handling and 300 watts maximum power handling.\u003c\/p\u003e\u003cp\u003eAn aluminum die-cast chassis supports the tweeter assembly, while a ferrite magnet provides the motor structure. The field-serviceable tweeter unit can be repaired using Pioneer’s compatible replacement diaphragm repair kit. This makes the TS-B351PRO a practical choice for systems where serviceability is important.\u003c\/p\u003e\u003cp\u003eThese tweeters work best as part of a properly filtered multi-speaker setup, not as standalone speakers. Pioneer specifies a 3,000 Hz crossover frequency and instructs installers to use the specified network. Pair them with appropriately crossed-over mid-bass speakers, a compatible amplifier, and secure mounting hardware for a balanced system upgrade.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.5-Inch Bullet Tweeters:\u003c\/strong\u003e Focused high-frequency drivers for multi-speaker car-audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTitanium Diaphragms:\u003c\/strong\u003e Provide a durable diaphragm material for upper-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150W Nominal Handling:\u003c\/strong\u003e Supports amplified systems with appropriate crossover protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100 dB Sensitivity:\u003c\/strong\u003e Helps deliver strong output with available amplifier power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Matches many compatible car-audio amplifier channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField-Serviceable Design:\u003c\/strong\u003e Allows replacement of the tweeter diaphragm assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe TS-B351PRO combines a titanium tweeter diaphragm with an aluminum die-cast chassis and ferrite magnet. Its bullet-style, horn-oriented layout is made for efficient high-frequency output, and the chassis is designed to provide a rigid mounting structure. No speaker grilles are included.\u003c\/p\u003e\u003cp\u003eConfirm fitment before installation: each tweeter requires a 3-inch cutout and 1-3\/4-inch mounting depth, with a 4-inch outer diameter. Mounting screws are included, but the system must use the specified crossover network; Pioneer cautions against operating the speaker independently. Secure the capacitor body and lead wire after wiring, and keep capacitor leads away from metal parts.\u003c\/p\u003e","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":45633235320902,"sku":"TS-B351PRO","price":91.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71YaxsnbEYL.jpg?v=1784419757","url":"https:\/\/audiowatt.store\/products\/pioneer-ts-b351pro-3-5-bullet-tweeters","provider":"Audio Watt Store","version":"1.0","type":"link"}
