MP 28.3:

1. Double Neodymium magnet optimized with FEA simulations, for maximum

field symmetry and exceptional transfer efficiency.

2. Tetolon Fiber dome optimized with FEA simulations, for excellent dynamics

and angle dispersion.

3. Larger rear chamber, to reduce Fs down to 90 0Hz.

4. Natural fibre non-woven sound-absorption material, for better damping and

more natural acoustic emission.

MP 165P.3:

1. 3 ohm nominal impedance to exploit all the amplifier’s power.

2. 14 mm height pure copper voice coil wound on a Polyamide former, for

exceptional power handling.

3. 95 mm diameter magnet to maximize the control over the whole excursion.

4. Exponential V-cone® prof ile pressed-pulp cone with cotton fibers,

combining stiffness and lightweight for a wide frequenc y response.
Cone prof ile geometrically optimized for utmost linearity and disper sion in
the mid frequency range.

5. “Boundary Free” rubber surround, for improved ef ficiency and wider

mid-bass frequency.

6. Low mounting depth, acoustically transparent aluminium alloy basket with

elegant diamond cutting and featuring the aluminium Hertz logo.

7. 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 165.3:

1. “Hi-Contour” two-position control, to select the tweeter hi-pass crossover

point according to the t weeter position/angle towards the listener.

2. Three terminals for tweeter level adjustment in 2 dB steps, to fine-tune the

transducer’s emission.

3. Extremely high quality bi-metallized 160V polyester film capacitors with

ultr a-low DF, for maximum soun d transparenc y and neat mid/hi-freque ncies.

4. Air wound inductors built on pure copper-wire with up to 1mm diameter,

for low losses on the woofer section where high transient currents are
demanded.

5. High power rating Wirewound resistors, to ensure performance stabilit y

even at high operating temperature. The Wirewound build construction
grants low parasitic series inductance thus reducing losses at high
frequencies, especially for resistors in series to the tweeter.
