The all-new TREO ENGINEERING RSX Integrated speakers are designed to deliver superior sound quality and terrific installation flexibility to the budget-minded audiophile. TREO RSX Integrated speakers were painstakingly designed and rigorously tested in our labs in the United States to deliver uncompromising audio fidelity in sizes to offer OEM fit in just about any vehicle on the streets of the twenty-first century. The efficient design of the TREO RSX Integrated speakers means they run well when powered by a high power head unit or a power amplifier.

TREO RSX Integrated speakers feature lightweight and durable injection-molded polypropylene cones laser-etched with the TREO ENGINEERING logo. These poly cones deliver smooth midbass response while the 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. TREO RSX Integrated speakers also feature an integrated 12 dB/octave passive crossover network for improved sound quality. Perimeter voice coil venting 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 frames and depth-minimizing motor structures of the TREO RSX Integrated 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 3", 4", 4x6, 5", 5x7, 6", and 6x9 sizes to fit the factory speaker openings in almost any vehicle whether it is a brand-new import or a domestic classic. TREO RSX Integrated speakers also feature low-profile multi-angle spade terminals for maximum installation flexibility.
