SB34 Subwoofer Kit with Passive Radiator

SB Acoustics SB34SWNRX-S75-6 Subwoofer + SB34NRX-00 Passive Radiator + SpeakerPower plate amplifier, with a 10% discount

Audiophile performance at an affordable price

The SB Acoustics woofers are known for exceptional performance and value. SB Acoustics drivers are designed in Denmark by engineers with many years of experience working for major Danish loudspeaker companies.  The engineering capabilities, coupled with the state of the art manufacturing facility in Indonesia, provide you with a product unmatched by other companies. 

This system uses the long stroke 12" subwoofer SB34SWNRX-S75-6 woofer.  This woofer features a stiff composite paper cone with rubber surround.  The 11mm linear excursion assures good control at very low frequencies.  A 3" diameter voice coil provides good power handling and fast response.  It is important to use a large magnet system to power a 12" speaker.   

Instead of a port, a passive radiator is used to tune the enclosure. The passive adds output and eliminates noises associated with using a port.  For low frequencies in smaller boxes, a proper sized port would be too long to fit in the enclosure. The passive radiator eliminates many undesirable effects of a port.

Blending the SB34 Kit into your stereo system is a breeze thanks to the Speaker Power line of subwoofer plate amplifiers.
