Pi–BASS
reviews
Manufacturer details
- Frequency Response: 20 - 200 Hz
- Efficiency: max. 99 dB / 1W / 1m
- Capacity: 200 W sinus
- Dimensions (W x H x D): 15 x 18 x 12" (38x46x30cm)
- Color: Piano Finish, white or black
- Weight: 85 lbs (38kg)
By developing the PI-Bass system, we have combined the Ripol® idea with our Acoustic Stealth Technology® - AST®. The result is a completely open system that has to move nearly zero air volume.
Voxativ PI-Bass is equipped with 2 x 96dB drivers = 99dB. This woofers do have a very low moving mass, a strong Neodymium motor and are extremely fast – as fast as Voxativ widebanders. The result is a powerful bass down to 20 Hz.
The PI-Bass woofer system is active and driven by a 250W class A/B plate amp. It has it's own adjustable crossover. We recommend a line connection to this system. High level entry is also possible. So the only thing you need to drive the woofer system is a speaker connector or preamp out or alternatively high level connection.
All features like: Level, crossover frequency and phase adjustments are implemented for the perfect adaption to every existing stereo system. We recommend a pair of these if used as bass extension. Of course this woofer system fits all the smaller Voxativ loudspeaker systems.

Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
At Voxativ, we follow the philosophy of absolute signal purity – this is why we design and build our own wideband drivers entirely in Berlin, without any crossover components in the signal path. One key innovation is our patented Acoustic Stealth Technology, which allows the drivers to produce full-range sound with stunning resolution and dynamics, all from a single voice coil.
Secondly, we believe in the synergy of engineering and craftsmanship: all our cabinets are handmade with precision joinery and fine veneers, acting as musical instruments rather than mere housings. This holistic approach results in a level of emotional engagement that we believe is quite rare in high-end audio.
What's your approach to customer support?
We always encourage customers to contact their local dealer or distributor first – they are part of the Voxativ family and trained to assist with all typical needs. However, if a customer prefers, or if the issue is more specialized, they are always welcome to contact us directly.
We pride ourselves on building long-lasting relationships with our clients, and that includes aftercare. Whether it's helping a customer reconfigure their system, adjust positioning, or even upgrade older components, we're always just a phone call or email away. We've even flown across the globe to personally install or fine-tune systems – because music, like friendship, deserves personal attention.
What are your favorite tracks for showcasing the strength of your products?
Keith Jarrett – Köln Concert (Part I): This piece shows how naturally and intimately our systems reproduce piano timbre and room acoustics.
Youn Sun Nah – My Favorite Things: Her voice, full of subtlety and nuance, is a great test of transparency and realism.
Yello – The Race: Dynamic, detailed, and rhythmically complex – a thrilling way to show off bass precision and soundstage layering.

Our take on the brand
SubmergeFound deep in the groves of your favorite LPs, and concealed in the soundtrack of the movies you can't wait to watch, is the critical low-frequency information that provides the the sense of space of the recorded music hall and the impact of the explosions the movie hero narrowly escapes. Submerge reveals the tension and sonic foundation below the surface of your audio experience.
Advanced Enclosure TechnologyOur precision-engineered and handcrafted X-Material enclosures, paired with an S-Material front baffle, bring you a level of vibration control that's simply without equal in the center channel market. Every note, every whisper, every thunderous explosion is delivered with unparalleled clarity and authority.
Cutting-Edge HardwareThe 1,600 watt amplifier is uniquely mounted to the massive heatsink plate found on the rear of the enclosure. Coupling the amplifier to the T6061 Aluminum back plate efficiently transfers heat from the internal components of the amplifier to the decorative heatsink fins, the design of which is inspired by the mountain ranges surrounding Wilson Audio.
Remove the handcrafted front grille to expose the sleek aluminum baffle design. The attachment hardware for this mass of metal is strategically placed underneath grille post catchers, ensuring a clean and visually pleasing appearance without compromising functionality.
Taking a page from the Master Subsonic's playbook, the combination of thick X-Material as a substrate coalesced with the bulk of the aluminum baffle create a truly solid and extremely damped surface for the Submerge driver to be secured to.

Our take on the brand
Basis shatters the notion that soundstage-enriching, deep and authoritative sub-bass must come from a large cabinet. Basis performs with the precision of a scalpel and the power of a sledgehammer. As a true ultra-fidelity subwoofer, Basis has huge bandwidth. It combines an entirely new, innovative driver, extreme cabinet engineering and an exceptional, wideband amplifier: Basis is capable of performing as nearly a full range speaker by itself.
When all of this capability is focused on the challenging and all-important sub bass region, the Basis proves its place well beyond the competition. Where other high-end subwoofers still struggle to avoid harmonic distortion, Basis delivers industry-leading behavior at the very lowest frequencies, with true fundamental bass for the discerning audiophile. It does this powerful work seamlessly, weaving bass energy into the expanded soundstage as if the Basis is an elemental part of the foundation.
Graceful curves and diminutive size belie an authority and strength we have only found to be bettered by our legendary Invincible subwoofer. For Basis, we incorporated a holistic design approach aimed at achieving the ultimate in high-end subwoofer performance. That we also achieved this in a compact package, one which can disappear sonically and visually in any listening environment, was a satisfying by-product of our process.
Listeners can enjoy a single unit, or stack multiple units in Duo or Trio configurations. This does much more than simply adding greater power: stacking loads rooms more evenly with bass energy, flattening modes more effectively than any other strategy. Basis lends beauty and soul to a reference-level system, delivering a meaningful improvement without adding any character of its own. Its quiet strength comes from thousands of hours of development focused on every single aspect of the design.
