PIONEER TS-B351PRO 3.5″ – 300 W Max Power Tweeter

Product Description:

The Pioneer TS-B351PRO is a 3.5-inch (87 mm), high-efficiency bullet style tweeter belonging to the Pioneer Reference for Open Show (P.R.O.) series, specifically engineered for car audio enthusiasts seeking serious sound pressure levels (SPL) and immense volume. Designed with a maximum peak power handling of 300 watts and a robust continuous output of 150 watts RMS, it effectively balances heavy power loads with extreme structural resilience. The driver incorporates a premium titanium diaphragm mounted inside a rigid aluminum die-cast chassis to keep acoustic vibration and structural distortion to an absolute minimum during intensive high-frequency reproduction. Thanks to an exceptional sensitivity rating of 100 dB, this horn-loaded bullet tweeter captures ultra-crisp, bright highs with high power efficiency, making it an excellent choice for broad, open-air or competition-style vehicle sound stages.

Product Features:

• Titanium Diaphragm & Horn Waveguide: Equipped with a lightweight, rigid titanium element coupled to an integrated horn throat to optimize directivity and maximize acoustic efficiency.
• Aluminum Die-Cast Chassis: Built inside a heavy-duty cast framework that completely dampens structural resonances and prevents unwanted sound coloration.
• High-SPL Sensitivity Rating: Features an ultra-responsive 100 dB efficiency level (1W/1m), allowing it to generate impressive, piercingly loud volumes without requiring excessive source energy.
• Field-Serviceable Construction: Engineered for heavy usage cycles, featuring a completely user-replaceable diaphragm unit for rapid maintenance or repairs.
• Focused High-Frequency Bandwidth: Tailored to safely reproduce frequencies stretching from a high 3,000 Hz up to 22 kHz.
• In-Line Crossover Support: Includes accompanying crossover protection capacitors to reliably isolate and block lower mid-bass frequencies from entering the tweeter coils.
• Compact Physical Dimensions: Formed with a standard 44 mm (1-3/4″) mounting depth and a 75 mm (3″) cutout diameter for precise baffle placement.
