The all-new TREO ENGINEERING RSX Component speakers incorporate all the custom design features and ear-pleasing sound quality of the TREO RSX Integrated speakers and add the flexibility of separate tweeter mounting and even better sound quality from an outboard 12 dB/octave Butterworth crossover network. TREO RSX component speakers were painstakingly designed and rigorously tested in our labs in the United States to deliver uncompromising audio fidelity in three different sizes to offer easy fitment into most modern vehicles. The efficient design of the TREO RSX component speakers means they run well when powered by a high power head unit or power amplifier.

TREO RSX component speakers feature lightweight and durable injection-molded polypropylene cones laser-etched with the TREO ENGINEERING logo. These poly cones deliver smooth midbass response while separate 20mm polyetherimide (PEI) tweeters provide crisp high notes and frequency response up to a stratospheric 22 KHz. The tweeters are protected by a custom-molded tweeter grill embossed with the TREO ENGINEERING triangle logo. The tweeters are supplied with cups that provide for angle, flush, or surface mounting. TREO RSX component speakers also feature an outboard 12 dB/octave passive crossover network for upgraded sound quality. The cooling vents integrated into the speaker frames mean these speakers are perfect for extended high volume enjoyment during those long drives when the music is your only company.

The proprietary TREO speaker frames and depth-minimizing motor structures of the TREO RSX component speakers were custom designed to fit into the unforgiving tolerances of the door panels of today's vehicles. TREO RSX Integrated speakers are available in 5", 5x7, ane 6" sizes to fit the factory speaker openings in most vehicles from brand-new imports to domestic classics. The outboard crossovers feature a compact, terminal-less design to facilitate hassle-free mounting and superior weather resistance inside door panels. TREO RSX component speakers also feature low-profile multi-angle spade terminals for maximum installation flexibility.

TREO RSX tweeters are also available in the RSX20t kit with 12 dB/octave outboard crossovers and mounting hardware.
