Our take on the Retrosound R-57N

by Buck Pomerantz
Retrosound

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Important Note: This is a single 5"x7" speaker, so you'll need to purchase a pair for vehicles with two 5"x7" openings.

Retrosound makes it easy to replace the factory speakers in almost any classic, vintage, or even new car. Their RetroMod Series speakers feature extremely shallow chrome 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.

The single R-57N 5"x7" 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 R-57N speaker features a powerful neodymium magnet and a low-carbon steel chrome 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 5"x7" with this updated Retrosound, and your tunes will sound new again, just like your classic ride.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

We stay on top of new products and technologies to help people make informed choices.

Features

Woofer: The speaker features a rigid pulp composite cone woofer with a Santoprene surround. The woofer uses a Neodymium magnet to achieve its shallow depth, so it fits 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).

Retrosound R-57N

Written By Anonymous, Street, Maryland on Friday, August 01, 2014
Crutchfield Customer Review (What's this?)
 
Although lacking in some bass and fulness of sound, it's a good solution to the single speaker location found in my old MG. Car noise prohibits any real sound system anyway. Serves my circumstances perfectly.

Retro Speaker in 66 Bronco

Written By Brian, West, TX on Friday, July 05, 2013
Crutchfield Customer Review (What's this?)
 
This speaker replaced a single in dash speaker in a 66 Bronco. Paired with a retro sound radio this speaker sounds pretty good. I am happy with the purchase and would recommend it for a single dash speaker replacement. The adjustable mounting bracket works great.
Pros:
Fits great in dash of 66 Bronco.

Tinny

Written By Kevin, NH on Sunday, May 26, 2013
Crutchfield Customer Review (What's this?)
 
I replaced a single center dash mono speaker so compared to that this is way better. In playing it with the Retrosound Model 2 I bought with it though it sounds pretty tinny. Maybe I just haven't found the right DSP setup on the radio yet. I wasn't expecting it to sound as good as a pair of nice speaker and I didn't have any other real choices so I gave it 3 stars.
Pros:
Easy install, with lots of options to make it fit. Dual voice voila
Cons:
Sounds tinny to me

Retrosound R-57N

Written By Jim, Orlando, FL on Wednesday, December 15, 2010
Crutchfield Customer Review (What's this?)
 
Too bad this speaker is the only available dual voice coil for older cars and trucks. It
works and is definately in better shape than the one I removed from my 1979 F-150 but it
seems to be lacking in clear highs and fullness in sound. I don't know, I'm no stereo
expert, but I have a RetroSound stereo driving this speaker in the dash and a 6 1/2"
speaker in each door and the 5x7 sounds weak...It works though.
