No les puedo negar que de aspecto me gustan bastante, siendo a mi gusto la rti10 la que más me gusta (esto por supuesto sin haberla escuchado).

No puedo dejar de mensionar que las viejas monitores rti fueron premiadas por stereophile comparándolas con las studio 20 y otras cajas más caras.

Creo que esta nueva serie es una buena alternativa para los que buscan buen sonido a precios correctos. Entiendo que en México esta marca está a precios muy competitivos, ojalá sea una buena opción.
