This bundle includes a Hertz Mille Pro Series MPX-1653 6.5" Pro Audio Two-Way Coaxial Speakers (Pair), a Hertz Mille Pro Series MPX-6903 6x9" Pro Audio Three-Way Coaxial Speakers (Pair) with Grilles, and 2x Metra 72-4572 Speaker Harness — Buick | Chevy | GMC 1986-2026.

1x Hertz Mille Pro Series MPX-1653 6.5" Pro Audio Two-Way Coaxial Speakers (Pair) (MPX-1653)

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.

Features -
• 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.
• 20 mm voice coil Tetolon fiber soft dome tweeter, featuring “Center Tuning Duct” geometry, for lower resonance frequency and reduced harmonic distortion.
• 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.

1x Hertz Mille Pro Series MPX-6903 6x9" Pro Audio Three-Way Coaxial Speakers (Pair) with Grilles (MPX-6903)

The three-way MPX 690.3 car audio coaxial, optimized for rear deck mount, features a 28 mm Tetolon tweeter with Neodymium magnet and faceplate profile maximizing the off-axis dispersion. A supertweeter strengthens the emission of very high frequencies and the basket radial venting system ensures low operating temperatures. The sound has an impressive impact and ensures perfect control, also with extensive high dynamic listening.

Features -
• 38 mm pure copper woofer voice coil wound on a Polyamide former for exceptional power handling and dynamic compression-free reproduction.
• Pressed-pulp cone with cotton fibers material, combining stiffness and lightweight for a wide frequency response.
• Large rubber surround designed for long throw and optimal sound damping.
• Over-sized ferrite magnet combined with very low carbon content iron plates, for low distortion at high power levels.
• Aerodynamic thus acoustically transparent aluminium alloy basket, eliminates rear wave reflections.
• Anti-vibration rubber magnet cover, damps spurious vibrations.
• 28mm voice coil Neodymium Tetolon fiber dome tweeter, for undistorted mid-frequency reproduction.
