OmnesAudio BB 4 black broadband 10 cm

The Tang Band broadband W4-1320 is one of the best known and most widely sold broadband in the 10 cm range. 
Not quite as successful as its little brother, the W4-655, it convinces with a finer resolution in the high frequency range. 
We had an OEM version built for the OmnesAudio from the W4-1320. 
The label on the product is W4-1320SMF. 
The underhang voice coil remains the same, as well as low distortion and optimal broadband frequency response.
