Compact passive car subwoofer with 30 cm (12") woofer with 300 W RMS or 600 W maximum power for rich sound.

Feel the beat! The auna CB300-4BX subwoofer in an extra flat construction with light effect, powerful sound characteristics and practically oriented design makes music sound rich.

In the low-resonance bass reflex case, a 30 cm (12") low-frequency subwoofer tirelessly pushes down to the lowest frequencies. The passive subwoofer delivers 300 W maximum or 600 W RMS power for low-pressure bass at the start and works completely in service with connected amplifiers. Next to its sound properties, the auna CB300-4BX substructure subwoofer scores with extra-flat overall dimensions and rugged housing with a durable felt coating. The small size allows for a flexible positioning under the driver's or the passenger's seat or the boot of the car. The cone made of polypropylene (PP) with rubber bead provides for particularly resonance-free vibration without transmission to the frame. Whether horizontal or vertical, the auna CB300-4BX can be installed quickly, unobtrusively and securely in the vehicle interior. It makes a special impression with its blue LED light effect, which provides the right atmosphere in the interior of the car. A 12V cable set for voltage supply is also included in the scope of delivery.

Bass pressure of the finest quality: with the auna CB300-4BX passive subwoofer.

What first struck me about the Auna CD300-4BX subwoofer is its compact size. I have a standard car sound system but wanted a little extra to boost the bass. That’s why I ordered this sub, which has definitely improved the sound (although it’s not powerful enough to blow out the windows, if that’s what you’re after!). For me the sub is loud enough and suits the size of my car just fine.

I purchased this subwoofer to use in a home 5.1 surround system. Sound is simply fantastic, when used with suitable power amp (recommend 2x200w at 8 ohms, but speakers are 4 ohms)and filter.Save a lot of money and buy a pair or even a quartet of subs and connect for a simply fantastic smooth sound.
