Two pairs of black 6.5 inch car coaxial speakers with integrated tweeters

Alpine

Alpine R2-S65 6.5" Coaxial Speakers (Two Pairs)

SKU CH-KS9Z-ES9RS

Two pairs of 6.5-inch coaxial speakers with glass-fibre cones and integrated tweeters reaching 40 kHz frequency response

  • TypeSpeaker
  • Hi-Res Audio certified with 40 kHz frequency response
  • Glass-fibre reinforced cone for fast, accurate music reproduction
  • Two pairs of 6.5″ coaxial speakers included
  • 2022 R-Series 2-way coaxial design with integrated tweeter
  • 5 cm door woofer delivers powerful low-end performance

Two Pairs for Full Vehicle Coverage

This set supplies two pairs of Alpine R2-S65 6.5-inch coaxial speakers, enough for front and rear door locations. They suit drivers who want a single-component upgrade that handles both midrange and high frequencies. Buyers needing a separate component system with external crossovers will not be served by this design.

Hi-Res Audio Certified Frequency Response

The 2022 R-Series line carries Hi-Res Audio certification and reaches a 40kHz upper frequency limit. Glass-fiber reinforced cones keep the 16.5cm woofers stiff and light for fast transient response during extended play. The integrated hard-dome tweeters maintain clarity at high output without the distortion that softer domes can introduce.

Direct-Fit Coaxial Installation

Each speaker combines woofer and tweeter in one basket, so installation follows a standard 6.5-inch door opening without extra mounting hardware. The coaxial layout removes the need to run separate tweeter wires or find dash mounting spots. Vehicles with non-standard depths or factory amplifier impedance mismatches may require additional adapters not included here.

Questions about this item

How much heat or power draw should I expect from the Alpine R2-S65 coaxial speakers during all-day use?

Passive speakers draw no power themselves; heat and electrical load come from the amplifier driving them, so match the amp RMS rating to the speaker power handling.

What amplifier or head-unit outputs are required to run the Alpine R2-S65 speakers?

You need a stereo amplifier or head unit with front and rear speaker-level outputs capable of delivering clean power within the speakers' RMS range.

Will the 6.5-inch Alpine R2-S65 fit the factory speaker openings in my older vehicle?

The 16.5 cm (6.5 in) frame matches many standard door cut-outs, but verify your vehicle's mounting depth and bolt pattern before installing.
