Our take on the Retrosound R-48N

by John Pollard
Retrosound

Important Note: This is a single 4"x8" speaker, so you'll need to purchase a pair for vehicles with two 4"x8" openings.

The right speakers for your vintage vehicle

Retrosound makes it easy to replace the factory speakers in almost any car — classic, vintage, or even brand new. Their RetroMod Series speakers feature extremely shallow baskets designed to fit into a wide variety of standard speaker locations. They may look old school, but Retrosound builds their speakers from the ground up, using the latest techniques and materials.

Designed for a single dash or deck location

The single R-48N 4"x8" speaker is designed for a classic car with only one speaker opening on its dash or rear deck. The woofer features dual voice coils, each one connected to its own tweeter. Your stereo receiver connects to both voice coils, so you get a stereo mix from a single speaker. In effect, you get two 2-way speakers in one frame, for modern sound in your vintage application.

The speaker fits in these vehicles:

Mercedes-Benz

  • 190C 1962-65
  • 190DC 1962-65
  • 200 1966-68
  • 200D 1966-67
  • 220B 1959-65
  • 220SB 1959-65

  • 230SL 1963-71
  • 250SE 1965-67
  • 250SL 1963-71
  • 280SE 1969-71

  • 280SL 1963-71
  • 300SE 1961-65
  • 300SEL 1962-65

BMW

  • 2800 (E3 SERIES) 1969-74

International

  • Scout 1961-65

General Motors

  • 1958 Cadillac
  • Chevrolet Chevelle 1966-67 (W/ Air)

Sturdy materials, detailed sound

The R-48N speaker features a powerful neodymium magnet and a low-carbon steel frame that form a strong foundation. The sturdy pulp composite woofer with its Santoprene surround delivers powerful performance while standing up to heat and humidity. The two Mylar dome tweeters broadcast detailed highs without sounding shrill, and their low profile helps increase installation options.

Although efficient enough to play well with any receiver alone, this RetroMod speaker can handle the high power from aftermarket amplifiers. Replace that wornout old 4"x8" with this updated Retrosound, and your tunes will sound new again, just like your classic ride.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Woofer: The speakers feature rigid pulp composite cone woofers with Santoprene surrounds. The woofers use Neodymium magnets to achieve their shallow depth, so they fit in tight factory locations.

Tweeters: Two Mylar tweeters are wired separately so this single speaker will accept a stereo input.

Dual Voice Coils: The woofer has dual voice coils, each wired with one of the tweeters. The stereo input is useful in many older cars with a single speaker location in the dash or rear deck. If used in a standard two speaker application the inputs should be wired in parallel (to present a 2Ω load) or series (to present an 8Ω load).
