Calven
Make listening part of the room.
Calven is a single-cabinet home system with a more substantial driver arrangement than the compact models in the collection. A central woofer handles lower frequencies, while two tweeters reproduce the upper range from the left and right channels.
The cabinet combines an engineered-wood structure, a removable fabric grille and a narrow metal control strip. Three physical dials provide volume, bass and treble adjustment. With the grille fitted, the front reads as one quiet surface; removed, it reveals the driver arrangement and its geometric layout.
Bluetooth supports everyday wireless listening. Stereo RCA and 3.5 mm inputs offer connections for compatible line-level sources. Place Calven on stable furniture with space around the rear port, then adjust its tone controls to suit the room and listening distance.
