The Best Coax Speaker for Harley Applications

The MPX165.3 speaker set is very different from other coax speakers on the market. This speaker has a high output soft dome tweeter built right into the center of the woofer magnet. This accomplishes three very important things.

  • All sound originates from the same point for a much smoother transition between high and low frequencies.
  • Uses the woofer cone to complete a larger horn flare, increasing the high frequency output. The lower frequency limit of the tweeter is also extended. This allows for bolder sound in the vocal range. 
  • Locating the tweeter in the center of the woofer eliminates having to find a place to locate the tweeter on the fairing of the bike. 

 Speaker Specifications 

  • 6.5" 2-Way speaker system featuring a pressed pulp cone with cotton fibers cone
  • Power range:
    • 100 Watts RMS
    • 200 Watts Peak Power
  • Frequency response: 45-21,500 Hz
  • Sensitivity: 92 dB/SPL
  • High density flux ferrite magnet


  • Drop in fit for batwing fairing '14 & up bikes (Electra, Street, Ultra Glide) when used with a stamped replacement speaker grill. You can find those here.
  • Fits nicely under the factory grill of '14 & up Road Glides. Requires that the rubber magnet cover is pulled off of the speaker so that the magnet clears the inside of the speaker pod. The magnet cover simply pulls off of the speaker.  
  • Fits all '13 & down Road, Street, Electra, Ultra Glides when used with our Harley 5.25" to 6.5" speaker adapter. Works with the factory grill on all of these bikes. You can find the speaker adapter here. 
  • Does not fit the tour pack pod locations on Ultra models of all years. A special speaker with a low profile magnet is required for Ultra speaker pods. 
  • The speaker terminals on these speakers work directly with the factory Harley speaker connectors.
