Frequently Asked Questions - Esotec MD 102 DYNAUDIO

How do I install the Dynaudio Esotec MD 102 tweeter?

Use the included mounting hardware. Cut a hole of 60 mm diameter with a depth of 18 mm. Secure the tweeter using the provided screws. Ensure proper crossover connection.

What crossover frequency is recommended for the MD 102?

The recommended minimum crossover frequency is 2.5 kHz with a slope of 12 dB per octave.

Can I use the MD 102 with an 8 ohm system?

The tweeter has a nominal impedance of 4 ohms. It may work with 8 ohm systems, but check overall system impedance and ensure the amplifier can handle the load.

How do I clean the MD 102 tweeter?

Gently wipe the dome and frame with a dry, soft cloth. Do not use any liquids or solvents. For the grille, use a soft brush.

Is the MD 102 compatible with other Dynaudio woofers?

Yes, the MD 102 is designed for the Dynaudio Esotec series and works optimally with Esotec woofers like the MW 162 or MW 182.

What is the power handling of the MD 102?

The tweeter handles 80 W RMS and 100 W peak. Exceeding these limits may cause damage.

Does the MD 102 come with a protective grille?

Yes, it includes a protective mesh grille to shield the dome from physical damage.

Can I use the MD 102 without a crossover?

No, operating the tweeter without a high-pass crossover will allow low frequencies that can damage the dome. Always use a crossover with a minimum cutoff of 2.5 kHz.

Where can I find spare parts for the MD 102?

Spare parts such as replacement diaphragms are available through Dynaudio authorized dealers or service centers.

What is the warranty for the Esotec MD 102?

However, the components can be damaged beyond repair unless a few ground rules are observed:

▶ Insure all components are properly installed and wired correctly.
▶ Observe the technical specifications.
▶ Always use high-quality cabling and amplification.

CAUTION

HIGH SOUND PRESSURE LEVELS

Listening to high sound pressure levels over a prolonged period of time may harm your hearing.

▶ To avoid auditory effects do not listen to high sound levels over a long period of time.
