Pioneer TS-MR1640 6.5" 160W marine coaxial speakers

SKU CH-JA9Z-HQ4BD MPN TS-MR1640

Water-resistant 6.5" marine coaxial pair handles 30W RMS with 91 dB sensitivity and 160W peak power

  • Speaker unit size6.5 in (16.5 cm)
  • 30W RMS continuous power for reliable marine audio
  • 160W peak handling delivers strong output when needed
  • 91 dB sensitivity produces clear sound with less amplifier power
  • 30 Hz – 30 kHz response covers deep bass to crisp highs
  • Water-resistant IMPP cone with Nomex damper withstands wet conditions

Marine coaxial speaker pair

The Pioneer TS-MR1640 is a 6.5" coaxial 2-way speaker set built for marine and outdoor audio systems. Each unit uses a water-resistant IMPP cone with a Nomex damper and a 27mm PEI dome tweeter. Sold as a pair, they suit boat owners who need durable sound reproduction on open water.

Power handling and headroom

Continuous power handling is rated at 30W RMS with a peak limit of 160W, so the speakers handle moderate amplifier output without strain. Sensitivity of 91 dB at 1W/1m means they play loudly on modest power, but sustained high-volume passages will reach thermal limits at the RMS figure. The 30 Hz to 30 kHz range covers full-range music, though deep sub-bass requires a separate subwoofer.

Installation constraints

A 5" cut-out diameter and 2-1/4" mounting depth define the space needed behind each panel, limiting use to locations with sufficient clearance. The 4-Ohm nominal impedance matches most marine head units and amplifiers, while the classic white grille fits factory aesthetics. Buyers needing larger cut-outs, different impedance or flush-mount hardware will need another solution.

Questions about this item

Will the 4-Ohm impedance and 91 dB sensitivity match my older marine amplifier?

The speakers present a 4-Ohm load and 91 dB sensitivity, so any marine amp rated for 4 Ohms at or near 30 W RMS per channel will drive them cleanly.

How can I verify the 27 mm dome tweeter and IMPP cone are performing correctly after installation?

Play a full-range test track; you should hear clear highs up to 30 kHz from the 27 mm PEI dome and solid bass down to 30 Hz from the water-resistant IMPP cone without distortion at 30 W RMS.

The pair comes with classic white grilles — what mounting hardware or wiring must I supply?

Grilles are included; you will need to provide 5-inch cut-out holes, 2-1/4-inch mounting depth clearance, speaker wire and any connector plugs for your boat's wiring harness.
