RetroSound R-57UK 5" x 7" Dash Replacement Speaker for Classic Vehicles

I have killer stereo in my classic Grand Prix. I could go into detail but that would not be useful to you. I was looking to improve my front sound stage to make it sound more in front of me. I cannot mount speakers in the A-pillars, I already have speakers up high in the doors. The speakers in the sides of the console and the kick panels cause what is known as "comb filtering" (sounds horrible) I tried speakers in boxes on the floor pointing up but that did not work either. My next experiment was a small center channel speaker on the dash facing the listener. Now I was onto something. However, it is a safety hazard if there was an accident. The factory 4x10 speaker was dried up and never had high fidelity even when it was new. I shopped around for 4x10s but needed something that was dual channel to maintain the stereo effect to work with my 10 channel digital signal processor. This speaker has a dual voice coil (DVC) main driver and two identical tweeters. This permits you maintain stereo separation and not electrically combine both channels. After manipulating some time delays and equalization the front sound stage effect is amazing. If I close my eyes, I cannot point right to the speaker that is producing the sound. If I turn my head left to right and the front sound stage stays in place. This speaker is exactly what I needed. 2/4/25 Update. I am STILL loving this speaker. The enhancement to my sound system has been quite surprising. I kind of thought it was a little pricy but after fine tuning my system with it included, it was worth every penny.

I was a bit taken back by the price, but since there were few options, I decided to order this for my classic Challenger. It was hard to install, as I had to modify the frame, and add a gasket to the bottom of the speaker, as mine mounted from the top. I also added a dust cover to the entire speaker, as I noted it had an open voice coil, allowing dirt to get into it. I then had to insulate the wiring on the right side, as it butted up against the top dash frame (which was metal), which would have shorted it out. Okay. It's in. It seems to have been well constructed and designed for odd situations such as this. I was surprised by how well it handled the output of my new stereo, and it actually sounded very good! Obviously, it couldn't have the separation of separate speakers, but it did a very good job with the twin tweeters. It sounded clear and bright, even at higher volumes. Very happy with purchase but would recommend having it installed by someone who knows what they are doing!

Had to modify to install in my 1970 mustang

It’s not hi-fi but it is way better than stock. Clear and fit with minor fabrication. Used on a 67 Tempest. No other speakers are in the car.

Using this in my 68 Firebird convertible where there is not much room to mount speakers. Now I can actually hear my stereo and has very good sound quality for a single speaker.

Why did you pick this product vs others?: Great fit great sound 👍🏼

sounds great

I've restored 2 classic cars recently and both needed a more modern radio and speaker set up. My 1-car received a single under dash speaker and 2-rear speakers. The other car received a R-57UK -5x7 speaker only. Wired correctly the R-57UK sounds better than the car with 3 speakers. Completely impressed with this speaker's performance.

Super Qualität!!

Sehr schön, dass es Hersteller gibt, die für so alte Autos noch Lautsprecherchassis anbieten. Der RetroSound R-69N ist flach genug, um unter die Federstäbe bei einem 58er Cadillac im Kofferraum montiert zu werden. Lediglich die Befestigungslöcher mussten etwas angepasst werden. Durch die 2 Spulen, kann er (Mono) sowohl im 4 Ohm als auch im 8 Ohm Betrieb eingesetzt werden. Das dazu notwendige Kabel ist ebenfalls dabei. Der Klang ist an diesem offenen Einbauort eh nicht so ideal, aber dennoch ausreichend für das alte Röhren-Radio. Ich bin sehr zufrieden damit und würde den RetroSound R-69N jederzeit wieder kaufen. PS: Das Anschlusskabel auf dem letzten Bild hat natürlich noch einen ordentlichen Adapter bekommen. Das auf dem letzten Bild war nur ein provisorischer Klang-Test nach dem Einbau. Hier in der 8 Ohm Verkabelung.

Das Doppel-Spulen-System halte ich für eine geniale Konstruktion, wodurch ich in meinem 1958 Cadillac Fleetwood Sixty Special das originale Röhren-Radio und zusätzlich einen versteckten Bluetooth Verstärker über den selben Lautsprecher betreiben kann. Den Klang halte ich für den Verwendungszweck für durchaus mehr als gut. Um weder am Fahrzeug noch am Lautsprecher Veränderungen vornehmen zu müssen, habe ich mir für den Einbau einen Adapter mit 3D-Druck angefertigt.

very nice, sounds great, came with multiple cables to configure in different ways...very pleased

Ich hätte bei dem Preis mehr erwartet; vor allem mehr Klangqualität. Da der LS aufgrund der erhöhten Bauform (Sickenumrandung) nicht passte, musste ich das LS-Gehäuse bearbeiten (Sickenumrandung kürzen), um die Abdeckblende im Armaturenbrett wieder einbauen zu können und konnte ihn aufgrund der Bearbeitung nicht wieder zurücksenden, was ich sonst gemacht hätte. Service beim Hersteller/Vertrieb schleppend.
