4" Neodymium Tweeter for car audio

The ALPHASONIK MPRO1 is a 4-inch neodymium tweeter built for automotive sound systems. It delivers high-frequency output with a 1.5-inch voice coil and a sensitivity of 103 dB. The unit fits factory locations using a 90 mm mounting hole and 47 mm mounting depth.

4 Ohm impedance and 175 W RMS power handling

This tweeter presents a 4 Ohm load and handles 175 Watts RMS continuously with a 700 Watt peak rating. The impedance and RMS figure are the primary specifications that determine amplifier matching and safe long-term operation in a component or coaxial setup.

Frequency response from 3 kHz to 20 kHz

The driver covers the upper midrange and treble from 3 kHz to 20 kHz, handling cymbals, vocals and harmonic detail with authority. It runs out of bandwidth below 3 kHz, so a separate midrange or woofer is required for full-range reproduction.

Questions about this item

How loud will the 103 dB sensitivity make this tweeter in a typical car install?

At 103 dB sensitivity, the tweeter produces high output with modest amplifier power, so it reaches loud listening levels without demanding a large amp.

What does the 4‑ohm impedance mean for amplifier matching?

The 4‑ohm load lets you wire one tweeter per channel on most car amplifiers or pair two in parallel for a 2‑ohm load if the amp supports it.

Will the 3.54 inch mounting hole and 1.85 inch depth fit my factory dash location?

The tweeter needs a 3.54 inch (90 mm) cut‑out and 1.85 inch (47 mm) of depth behind the panel; measure your opening to confirm clearance.
