DS18

DS18 MP4TPBK HYDRO 4 inch Marine Tower Speakers 300W Black Pair

SKU CH-JT9Z-SWE72

Four-inch marine tower speakers handle 50 W RMS each and mount securely on smaller vehicles subject to vibration

  • 4 inch diameter fits tight tower mounts
  • 50 watts RMS delivers clear mid-range output
  • 150 watts peak handles dynamic transients
  • 89 dB sensitivity produces loud sound with less power
  • 115 Hz to 20 kHz range covers vocals and highs

Compact Tower Pods

DS18 MP4TPBK HYDRO 4 inch Marine Tower Speakers deliver 50 watts RMS per unit with a maximum of 150 watts. The black pair suits smaller vehicles that experience heavy vibration. A redesigned clamping system keeps each lightweight pod secure during rough use. Sensitivity reaches 89 dB for clear output.

Build Integration

Each pod presents a 4 ohm nominal impedance for standard amplifier matching. A 120 Hz high-pass crossover is recommended to protect the drivers. The compact diameter allows installation where larger towers cannot fit. No additional mounting hardware is described in the specifications.

Thermals and Power

RMS power handling is 50 watts with peaks up to 150 watts per speaker. Frequency response spans 115 Hz to 20 kHz for full-range reproduction. The marine-grade construction resists moisture and UV exposure during normal operation. Efficiency remains steady at the rated sensitivity level.

Questions about this item

How much continuous power can each 4-inch tower speaker handle before thermal limits?

Each speaker is rated for 50 watts RMS continuous power handling, which is the thermal limit under sustained use.

What is the sensitivity and impedance, and how do they affect heat and amplifier demand during all-day playback?

At 89 dB sensitivity and 4-ohm impedance, the speakers draw moderate current; an amplifier delivering clean 50 W RMS per channel will run warm but not excessively hot during extended sessions.

What amplifier crossover setting and mounting hardware are required for these marine tower pods to function correctly?

A high-pass crossover set at 120 Hz is recommended, and the redesigned clamping system mounts directly to standard tower tubing without extra brackets.
