About the RetroSound R-57N
From our tech experts at CEN
The RetroSound R-57N is a single 5x7 inch 2-way dash speaker with dual voice coils, supplied with the RS-UB1KT Universal Speaker Bracket, wire and screws. It plays a full stereo mix from one speaker, handling 60w RMS and 100w peak at 4+4 ohm, with 87 dB sensitivity and a 65 Hz to 21 kHz range. Silk tweeters and Santoprene surrounds keep it smooth.
Who it suits
Classic car owners with a single central dash speaker location, where cutting extra holes is not an option. At just 50.5mm deep, it is the slimmest option in the range for shallow dashboards. The 6.5 inch R-65N is the alternative size in the same Premium range.
Our tech experts advise
A neodymium motor and dip-cut design keep the mounting depth to 50.5mm, but measure the space under the dash before ordering. Wire both voice coils to the left and right outputs so neither channel is lost. No grille is included. Get in touch and we will check the fit for your car.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Is the RetroSound R-57N sold as a single speaker?
A: Yes. This listing is for one 5 x 7 inch speaker with one universal speaker bracket, wire and four screws. Its dual voice coils produce a stereo mix from a single speaker location.
Q: What is the mounting depth of the R-57N?
A: 1.98 inches (50.5mm), thanks to its neodymium magnet structure.
Q: What impedance is the RetroSound R-57N?
A: It has dual voice coils rated at 4 + 4 ohm, with power handling of 60 W RMS and 100 W peak.
