The beginning of the Quadre Escènic as a stable group cannot be considered, however, until after the period of the Civil War and the Second World War had passed. Theatrical culture once again made its place on the airwaves, and it was in 1947, when Joan Llenas i Bartoló, then a broadcaster for Ràdio Terrassa and a great theater fan, gathered a group of voices to form the station's first stable Quadre Escènic. This allowed for radio theater performances on par with those being performed on all the stations at that time. This first stable Quadre Escènic was named the Compañia de Comedias de Radio Tarrassa and debuted on July 15 of that same year with the play "El ladrón".

Among the members of this period were names such as Rosa Maria Martinez, Teresa Figueras, Elsa Campoy, Maria Teresa Padrós, Concepció Casanovas, Maria Teresa Vázquez, Paquita Rovira, Amparo Martí, Lidia Segués, Julia Morales, Micaela Pedrola, Maria Glòria Farrés, Juanita Palau, Odette Pinto, Josep Alemany, Josep Burgués, Ventura Riera, Jesús Colomer, Jordi Massaguer, Ramon Bravo, Joan Garrigó, Lluís Jordà, David Mir, Josep Armengol, Jordi Campà, Anselm Marcet, Gabriel Alonso, Guillermo Salceda, Rafael Peris, Salvador Llach, Albert Puig, and Llenas himself, among others who were incorporated and formed a group not only with a high artistic level, but also united by a firm friendship that was enriched day by day.

A historical event occurs that is still remembered today. It was customary, in those years, to represent, around All Saints' Day, the drama of "Don Juan Tenorio" by Zorrilla, and the Quadre Escènic wanted to carry out this representation facing the public and as if it were conventional theater. Thus, on October 30, 1951, and in front of a devoted audience, among whom were the actors Conrado Sanmartin and Paco Rabal as guests of honor and the actor of the Quadre de Veus of Radio Barcelona Isidro Sola, the Quadre Escènic of Radio Terrassa achieved great success, and consolidated itself as one of the most active radio theater groups of the time. Two days later, the same work was represented again, in this case, however, at the Teatre Cinema Domènech of Rubí. Later, they also frequently performed and performed different works in different halls in towns throughout the province and also performed on other stations such as Radio Sabadell and Radio Manresa. In these performances outside the radio studios, the director Joan Llenas had the help of Francesc Izquierdo as artistic director, and between the two they directed the voices of the Stage Picture.

But the disappearance of the Quadre Escènic was only a temporary event. The recovery of radio theatre had its starting point in the wake of a key event. In 1983, Lidia Segués, the station's announcer and radio theatre actress of the 1950s, who had started at the Quadre Escènic in 1951 but did not become part of the announcers' staff until 1957, celebrated her 25 years of radio work. For this occasion, a group of former colleagues from the Quadre Escènic from the previous stage paid tribute to her with the performance of "Les vinyes del Priorat" by Josep Maria de Sagarra, a work that she herself had already performed in the previous stage and in which she is participating again. Maria Glòria Farrés, Juanita Palau, Albert Puig, Anselm Marcet, Manuel Arisó, Rosa Torrens, Ramon Bravo, Lluís Montull and Joan Garrigó participated alongside her. Aquesta celebració torna a despertar la inquietud del teatre radiofònic a tots ells, de manera que, d'acord amb la direcció de l'emissora, es tira endavant un nou projecte per reactivar el Quadre Escènic. Les noves sessions de radioteatre, que al principi s'ofereixen amb caràcter bimensual, compten amb les veus encara actives de l'etapa anterior, però també s'hi afegeixen noves veus més joves. La direcció d'aquest Quadre de Veus s'encomana a Joan Garrigó, i Rafael Peris assumeix la tasca d'adaptador i guionista de les obres que es posen en antena. D'aquesta manera es forma un grup estable i totalment amateur que segueix una disciplina i serietat que permet complir els objectius establerts i oferir un producte de qualitat a l'audiència. Així, amb la col·laboració desinteressada de tots els seus components, aquest Quadre de Veus és converteix en una oferta única dins el panorama radiofònic del moment, ja que les iniciatives d'altres emissores per reviure el Els components del Quadre de Veus de Radioteatre, el 1.986teatre radiofònic, han topat amb la dependència professional dels seus actors i ho han estat capaces de continuar endavant.

In the midst of the artistic stage of the Radio Theatre Voices Group, on February 21, 1989, Rafael Peris, the group's scriptwriter and adapter, died suddenly. A year later, on February 17, 1990 and at the Catholic Social Center, Rafael Peris received an emotional posthumous tribute from his colleagues with the interpretation of "Yerma" by Federico Garcia Lorca in front of a packed amphitheater. This moment also represents the resumption of the radio theatre sessions with an audience that had already been held in the previous stage.

The good reception of the tribute session to Rafael Peris moved a new representation of "Yerma" to a larger stage, that of the Caixa Terrassa Cultural Center, on November 10, 1990. Aquesta representació marca l'inicia d'un període de posada en escena de diferents obres i de col·laboració amb diferents entitats per fer lectures dramatitzades.

On January 28, 1995, the Quadre de Veus performed again on the stage of the Cultural Center, in this case, with the interpretation of "Agnès de Déu" by John Pielmeier, achieving a success at the same level as that of the previous performance.

During these first years of the 21st century, the Quadre de Veus continues to incorporate new actors and actresses into its cast, and works such as "Bajarse al moro" by José Luis Alonso de Santos, "El banyut imaginari" by Molière, "El proceso de Oscar Wilde" by Maurice Ronstad, "El zoológico de cristal" by Tennessee Williams, "Escuadra hacia la muerte" by Alfonso Sastre, "Fulgor y muerte de Joaquín Murieta" by Pablo Neruda, "L'assassinada de la senyora Abril" by Josep Maria de Sagarra, "L'habitación" by Harold Pinter, "La casa de Bernarda Alba" by Federico García Lorca, among others, are performed.

On January 28, 2010, the imminent closure of Ràdio Terrassa's broadcasts was announced. Two days later, on January 30, the last play on this station was broadcast, "Cándida" by Bernard Shaw, which also became the last local production space to be broadcast on Ràdio Terrassa. This marked the beginning of a brief period of absence of radio theatre on the airwaves, but not of the activity of the Quadre de Veus, which continued to maintain the commitments acquired with the different organizing entities of the events that were already scheduled.

The first five seasons on 95.2 Ràdio, the Radiofònic Theatre was broadcast monthly. From the 2015-2016 season until 2022 - 2023, the Radiofònic Theatre is broadcast weekly, combining new recordings with the broadcast of old works that are preserved from the years of the second stage of Ràdio Terrassa, reaching a total of more than two hundred broadcasts. From the 2023-2024 season, e4s returns to monthly frequency and is committed to intensifying production and new recordings.
