【Diamond 165-3 ACTIVE｜16.5cm 3-way speakers for straightforward enjoyment of music itself】

The Diamond 165-3 ACTIVE is for those who want to enjoy their music a bit more carefully—replacing the factory speakers to bring out vocal expressions and the finer sounds of instruments. Built as a 16.5cm 3-way configuration, this speaker system aims for a natural reproduction that’s easy to listen to even over long periods, while extracting the information content of music thoroughly.

Developed as a new series and the successor to the RS Revelation 165-3 released in 2016, it is designed to reproduce music itself without adding unnecessary tonal coloring. It’s the type of speaker where even familiar tracks yield new discoveries—your usual vocals may feel closer, and the positioning of instruments and the decay/reverberation of sounds become easier to understand.

The tweeter uses a silk dome with a coating treatment. The midrange employs a magnetic circuit combining a 26mm-diameter voice coil with a small neodymium magnet. Designed with an emphasis on high rigidity, resolution, and reproducing ability, it reproduces even the subtle nuances of vocals and the mid-to-high frequencies with care.

Because this model is a passive-less (passiveless) specification, it is not intended for setups that use a typical passive network. Instead, it’s suited to systems that individually drive and adjust each speaker. When combined with a DSP and/or a multi-channel amplifier, it’s a speaker whose final sound quality is heavily influenced by how you choose to tune and play it inside the vehicle.

Speakers don’t produce the same sound just by installing them. You need to consider everything—from door treatment and installation method, the placement of each unit, the overall system combination, and even the final adjustments. If you’re considering the Diamond 165-3 ACTIVE, it’s recommended that you sort out the system together in a practical, no-stress way, while confirming your vehicle model, your current audio setup, the music you typically listen to, and the sound direction you want.
