Notes[edit]
Historical/Technical Background
The B 9251 were produced at the Funkwerk Köpenick for Stern Radio Sonneberg from 1978 on. For the first time in a compact speaker a 40 W woofer was used. The L 2921 (4 Ohm) was based on the L 2911 of the Rema Toccata boxes. However, a 12 cm magnet and a reinforced plunger coil and diaphragm were used. The somewhat undersized L 5904 tweeter (8 W / 8 Ohm) was taken over unchanged from the Toccata. Due to this configuration and the small cabinet the speakers sound very bass-heavy and are best suited for amplifiers with high output power like the Sensit control units. The B 9251 are rated at 35W and weigh 7.5kg each.
