Polish company Virtual HiFi has officially entered the loudspeaker market with the launch of its first model, the Virtual HiFi Viper. The brand, founded by Grzegorz Rulka—also known for Cube Audio and Qualio—has so far focused on 3D-printed audio accessories, but the Viper marks its first full-scale speaker system.
A Fresh Take on Speaker Design
The Viper is a compact bookshelf loudspeaker that aims to deliver big sound from a relatively small footprint. Its cabinet is entirely 3D-printed from PETG, with 10 mm thick pyramid-shaped walls that reduce unwanted resonance and vibration. Unlike traditional MDF or plywood enclosures, the stiffer PETG structure improves rigidity, and each cabinet takes more than 120 hours to print. The result is finished in a smooth satin surface available in multiple colors.
Drivers and Acoustic Engineering
At the heart of the Viper is a Dayton Audio Epique mid/bass driver with a 150 mm carbon-fiber cone and long 14 mm excursion, supported by a pair of 180 mm passive radiators mounted on the cabinet’s sides to extend low-end response down to 40 Hz.
High frequencies are handled by a Mundorf AMT dipole tweeter with a large diaphragm, chosen for its wide dispersion and airy, open sound. To minimize cabinet interaction, the tweeter is mechanically decoupled via a 3D-printed TPU connector.
High-End Components Inside
The internals follow the same audiophile philosophy: Duelund tinned copper wiring, Mundorf MCap EVO capacitors, MResist Supreme resistors, and wax-impregnated litz wire coils are all part of the crossover network. Around the back, a 6 mm stainless steel panel houses premium WBT Nextgen silver binding posts.
Power Hungry but Compact
With a sensitivity of just 83 dB and a 4-ohm load, the Viper is not an easy speaker to drive. Virtual HiFi recommends using at least 200 watts of amplification for best performance. The speaker is best suited to small and medium-sized rooms or near-field setups, and even includes a built-in 80 Hz high-pass filter for seamless pairing with a subwoofer if deeper bass is needed.
Size, Finish, and Price
Despite its boutique build, the Viper remains relatively compact at 32 × 17 × 22 cm and 11 kg per speaker. Buyers can choose from black, white, grey, beige, or yellow finishes.
The Virtual HiFi Viper is available to order now in Europe at a recommended retail price of €6,900 per pair.
