MPK 165.3
TWO WAY SYSTEM
220 W
MP 25.3:
1. Tetolon fiber soft dome, for a natural yet detailed reproduction of musical
nuances.
2. “Center Tuning Duct” geometry, for lower resonance frequency and reduced
harmonic distortion.
3. High density flux Neodymium magnet, optimized for utmost control during
high energy dynamic transients in the mid-high frequency range.
4. 25mm ferrofluid-cooled mobile voice coil.
5. Rear chamber filled with selected damping material and sized for lower Fs,
to ensure a well damped high pass frequency roll-off, allowing low cut-off
frequency crossover point.
6. Faceplate featuring FEM (Finite Element Modeling) optimized geometry, for
high linearity in off-axis installations.
7. Wide array of installation accessories, for an easy OEM integration.
MP 165.3:
1. Pure copper voice coil wound on a Polyamide former for high power handling
combined with very low intermodulation distortion of vocals.
2. Exponential V-cone® profile pressed-pulp cone with cotton fibers, combining
stiffness and lightweight for a wide frequency response. Cone profile
geometrically optimized for utmost linearity and dispersion in the mid
frequency range.
3. “Boundary Free” rubber surround, for improved efficiency and wider
mid-bass frequency.
4. High density flux ferrite magnet combined with very low carbon content iron
plates, for low distortion at high power levels.
5. Low mounting depth, acoustically transparent aluminium alloy basket with
elegant diamond cutting and featuring the aluminium Hertz logo.
6. Full protection metal mesh grill featuring the aluminium Hertz logo and
attractive look mineral powder coated inner grill are included for several
install combinations.
MPCX 2.3:
1. Two-position (0 / +2 dB) switch for tweeter level adjustments, to fine-tune
the transducers emission.
2. 160V extremely high quality bi-metallized polyester film capacitors with
ultra-low DF, for maximum sound transparency and neat mid/hi-frequencies.
3. 1mm pure copper wire low series resistance inductors, for low dissipation
losses on the woofer section where high transient currents are demanded.
4. Small footprint design for easy installation, with top vent grille for efficient
heat dissipation.
