Welcome

Regular floorstanding speakers cover most frequencies, but subwoofers specialize in reproducing the lowest bass notes between 20 and 60 Hz. These ultra-low frequencies create physical sensations that extend beyond just audible sound.

Advanced subwoofers use digital signal processing (DSP) to control resonance and prevent standing waves. This precise control ensures tight, accurate bass reproduction instead of the bloated, muddy sound that plagues lesser subwoofers.

Room placement is critical for subwoofer performance due to the unique behavior of low frequencies. Bass waves can either constructively or destructively interfere based on room geometry and listening position. Many rooms benefit from the combined sound smoothing behavior of two amplifiers instead of one.

Hifi-focused subwoofers—as opposed purely home theater-focused—have the same intricacy as high-end speakers: they can punch with the speed and accuracy to match with your music perfectly—and not just be loud and gut-punching.

Wilson Audio
Subsonic

Reviews
The Wilson Audio Subsonic is the fraternal twin of the WAMM Master Subsonic. It features the same subwoofer drivers and the same internal volume. The differences lie in the finish details. The metal work in the WAMM Master Subsonic features the prismatic finish that mirrors (no pun intended) the WAMM's main array gantry. On the Wilson Audio Subsonic, the metal work is from Wilson's main line finish process—the same level of metal finish that has adorned Wilson products throughout the line.
Wilson Audio is often considered the quintessential American high-end hi-fi brand, a staple in premium audio dealerships across the country. Many reviewers use Wilson speakers in their own home systems, reflecting their reputation for outstanding dynamics, bass depth, and the ability to reproduce classical music with remarkable realism. Wilson focuses on creating an uncolored sound, aiming to replicate the experience of live, unamplified performances.
Expand Details

What reviewers think

Product Strengths

  • Subsonics allow the listener to not only hear the bass, but also to feel it, making the experience more immersive and powerful
  • Measurements showed very flat, very smooth response, plus or minus maybe 1 dB using pink noise
  • The blend is beautiful

Product Considerations

  • Each subwoofer is $41,000 US, the crossover is another $5,500, and an amplifier is also needed

Takeaway: The subsonics offer a unique and immersive listening experience, allowing one to not only hear, but also feel the music, making it more powerful and realistic. If one wants the best sound and has the budget, the subsonics could be a great choice.

REL
No.32

Reviews
No.32 enjoys the rarefied position of elevating our Reference range to an even higher orbit. No.32 retains the exquisite beauty of our curvilinear reference cabinets, an updated 15" (380mm) true carbon fibre driver and our ultra-reliable NextGen 7 Class D 1,000 watt amp outfitted with thin film capacitors, higher gain and superior limiting. The net result is a flagship model that stretched the edge of the art further with superior dynamics, richer tonal color, and a freer, more expressive character that opens up the midranges and highs in an unprecedented manner.
REL is widely recognized as the premier audiophile-grade subwoofer manufacturer, focusing exclusively on designing subwoofers that match the speed and clarity of high-end loudspeakers. Their higher-end models are specifically designed to integrate seamlessly with audiophile speakers, enhancing the soundstage and instrument separation rather than simply adding bass impact.

  • Deep bass output and really good bass extension, with REL claiming -6dB at 15Hz
  • Exquisite paint finish with 12 coats of final lacquer applied, with each subwoofer taking 5 weeks in total to build
  • The remote control and digital display make it a very nice way of setting things up, and then after dialing in, the remote is probably not needed again

Product Considerations

  • It is a huge and very heavy subwoofer, weighing 85 kilograms
  • The handles on the side are useful for lifting such a heavy unit, but they are not very nice to look at

Takeaway: The No.32 is a top-of-the-line subwoofer that offers exceptional bass performance and exquisite build quality. It's perfect for audiophiles who want the very best and have the space to accommodate it.

Reviews
Timpani, Kick drums, kettle drums, these are all great examples of instruments that inspired the innovation of Wilson Benesch infrasonic technologies. Each musical instrument creates low frequency sound with attack and dynamics that hit you in the chest. The IGx seeks to recreate this experience of live music using innovative technologies including the push-pull motor design, a rounded geometric enclosure that mimics these instruments and a super lightweight Carbon Fibre – Polyethylene Terephthalate diaphragm.
Wilson Benesch pioneered the use of carbon fiber in audio products, starting with their 1991 turntable, and continues to use this material extensively in their loudspeakers for its unique structural advantages. Their speakers feature an isobaric driver configuration that enables deeper bass from smaller cabinets, and they manufacture almost all components in-house, including their distinctive curved monocoque enclosures that reduce resonance.
Expand Details

What reviewers think

Product Strengths

  • Extends the spectrum of even large floorstanding loudspeakers down to the abyssal low end of 12 Hertz, while achieving this homogeneously, discreetly, and naturally
  • Superb filter network works smoothly from 30 to 90 Hertz
  • Can be tuned to the speaker in just a few simple steps, making adjustments easy
  • The level control is tuned from -30 to +60 dB so that the woofer can disappear acoustically or come to the fore without ever becoming too present or annoying
  • The effect on the homogeneity and plasticity of voices, instruments or imaging is impressive

Product Considerations

  • The phase control only serves to compensate for placement errors, ideally the subwoofer should be positioned exactly in line between the speakers

Comparisons (according to reviewers)

  • Vs Wilson Audio Sasha V: Resulted in a subtle gain in liveliness, stage size and plasticity, which was clearly felt after just a few words of Suzanne Vega's "Tom's Diner"
  • Vs PS Audio FR10: A crossover frequency of 58 Hertz at a slightly raised +10 dB proved to be optimal—which only added an imperceptible amount of low bass to the speaker

Takeaway: The IGx is a high-end subwoofer that enhances the overall sound experience by adding subtle gains in liveliness, stage size, and plasticity to the music, making it more palpable and vivid It integrates seamlessly with existing speakers, improving the homogeneity and dimension of the sound reproduction
