SB34 Subwoofer Kit 
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.

Why use SpeakerPower?

There are many unique benefits to working with SpeakerPower:
  • Designed, assembled and tested in Santa Ana California. The 2400W-6000W amplifiers are made entirely with local vendors and qualify for MADE IN USA.
  • Lead times are short. Amplifiers are built to order as you need them. Quantity commitments are small.
  • Custom faceplates, silkscreens and other features are easily accommodated.
  • Some models have UL/CSA approval as a standalone product. This means you don't have to pay for an expensive UL investigation, quarterly inspections of your manufacturing, calibration of test equipment etc etc. The combination cUL mark is already screened on the faceplate.
  • SpeakerPower has over 30 years experience designing and manufacturing loudspeakers and amplifiers for some of the biggest names in the business.
So while piecing together your own amp may appear to be less expensive, when you consider the total cost of time to market, UL/CSA, inventory, engineering etc you will find the SpeakerPower turnkey solution to be very competitive.

SB Acoustics SB34NRX-00 12" Coated Paper Cone Passive Radiator

This passive radiator is a good match to the SB Acoustics woofer SB34SWNRX-S75.  In 2.0 to 2.5 cubic foot box this combo will get down to 30Hz.  Adding the plate amplifier with a low frequency boost can push the F3 even lower.
