Esosub B9S Shallow-Mount Pre-loaded Enclosure Subwoofer

Esosub B9S is a closed-box subwoofer model with a floor-facing speaker, square shape and quite compact size so users can place it behind the last bench. This is the ideal choice for those who need to upgrade the bass range but do not have the conditions or intention to affect the floor surface.

According to Dynaudio, the Esosub B9S speaker cabinet is made from MDF wood with a smooth, rough surface, similar to the Core Series speaker cabinets for professional audio equipment. Users can also fix the Esosub B9S speaker to the floor with hook-loop fasteners to limit the speaker from slipping while the vehicle moves through many different terrains. 

Through a large diameter woofer and a speaker cabinet with a volume of up to 14L, the Esosub B9S can reproduce powerful, energetic and accurate bass as intended by the music composer. The speaker has an impedance of 4 Ohm and sensitivity up to 83.3dB, which means it is compatible with many amplifier systems available in cars and helps users save a significant amount of money.
