- CONCENTRIC COAXIAL TWEETER: built in the woofer voice coil, achieving one single point of emission, to re-create the virtual sound-stage like in live music performances.
- TWEETER SUPPORT WORKING AS A REAR CHAMBER: sized for low Fs, to ensure a well damped high pass frequency roll-off, allowing low cut-off frequency crossover point.
- 36 MM PURE COPPER WOOFER VOICE COIL: wound on a Polyamide former, for outstanding power handling and dynamic compression-free reproduction.
- PRESSED-PULP CONE WITH COTTON FIBERS: combining stiffness and lightweight for a wide frequency response. Cone profile geometrically refined to perfectly match with the tweeter emission ensuring phase consistency in the crossover area.

Review highlights
Based on customer reviewsHertz MPX 165.3 PRO — clear, loud 6.5" coaxials with strong bass
These Hertz MPX 165.3 PRO coaxial speakers deliver crystal‑clear, full‑range sound and impressive loudness for 6.5" speakers; they reveal their best dynamics when paired with a dedicated amp or upgraded head unit.
What buyers praise
- Crystal‑clear, detailed mids and highs
- Punchy, well‑defined bass for a 6.5" speaker
What to watch for
- Perform best with a dedicated amplifier and/or better head unit to fully unlock dynamics
Overview
The coax tweeter concentric to the woofer of the MPX 165.3 car audio coaxial speakers allows for one single linear-phase emission point, for a natural timbre providing a detailed sound stage. Thanks to the “Center Tuning Duct” geometry, the tweeter resonance frequency is especially low and the employment of damping materials for the inside provides for a linear acoustic emission. The acoustic lens optimizes its off-axis response, which is typical with door installation of coax speakers; besides, the 36 mm diameter woofer generates deep and controlled bass frequencies.
