Yes. Our Vienna Series satellite speaker systems are designed to deliver exceptional full-range sound when paired with 1 or 2 subwoofers or low-woofers, providing a deep and immersive audio experience in a 2.1, 2.2 or 5.1, 5.2 channel sound system.

Yes. All Neiss Loudspeaker systems come with a limited lifetime warranty to the original purchaser against material defects, reflecting our commitment to quality and craftsmanship. This warranty ensures your investment is protected for the lifetime of the product. We also provide a service guarantee to the original purchaser for all non-warranty repairs that may be needed (e.g. from user damage) for a reasonable bench fee, ensuring that your Vienna Series can be enjoyed for a lifetime. (Note – As each speaker system is hand made in limited quantities, the manufacturer reserves the right to substitute materials of comparable, or superior, quality on any warranty repairs.)

Inspired by the minimalist design school, Neiss Loudspeakers are designed to achieve maximum coherence in the spatial, frequency and time domains, resulting in more natural sound. To start, Neiss Loudspeakers are imagined as sonic-pistons, efficiently and directly translating an audio signal into sound with the fewest, high-quality materials and as little interference (or audible distortion) as possible.

A guiding design principle at Neiss Loudspeakers is that the most reliable way to reproduce an engaging stereo image is through a single point source per channel, within a speaker system mechanically engineered to mitigate diffraction losses, preserve signal-coherence in space, as well as to preserve time-coherence and tonal quality and timbre with musical drivers, low distortion motor and magnet designs, and a minimally complex internal crossover circuitry (made with the finest components available), or even no internal crossover circuitry where appropriate.

Finally, Neiss Loudspeakers are engineered with wide radiation patterns for more consistent off-axis response (as listeners move around the listening space) and the strongest solid-wood cabinets to better protect against a lifetime of foreseeable incidents (being dropped or knocked over). Embracing simplicity and a cost-no-object build philosophy allows Neiss Loudspeaker systems to be the ultimate lifestyle speakers: Delivering full range audio with rich, natural timbre that is detailed, but never fatiguing, and to guarantee a lifetime of performance to the original owner.

To achieve coherence in both the signal and time domains, Neiss Loudspeakers begin with a single point-source per channel, providing a more coherent audio signal than conventional multi-way speaker designs. In conventional designs, low and high frequencies are reproduced from separate sources located at different heights / locations, creating different phases for the low and high frequencies. Removing this limitation, the intention is for the point source design to deliver frequencies at the same time and in the same place, subjectively creating a fuller, deeper and more natural soundstage for listeners, when projected over stereo, satellite channels.

Specifically, this effect is achieved because in reproducing a musical scale, fundamental notes are derived from low frequencies and harmonic notes are derived from high frequencies. Where fundamentals and harmonics in a recording originate from a single voice or instrument – but are reproduced from separate source locations on a speaker – there can be discernible spatial incoherence (from differing image heights / sound-source elevations), creating opportunities for time-delays as well as a diminished soundstage and stereo image. Further, because sound sources are directional at high-frequencies (narrowing as frequencies get higher), multi-way speaker designs can exacerbate phase-shifts (that present as audible peaks and dips in frequency response), increased room interference, and imaging problems as listeners move around the space. Matching the directivity and phase of the low and high frequencies with Neiss Loudspeaker’s single point-source design eliminates these problems inherent in conventional multi-way speaker designs, resulting with a stereo image that presents with uncommon depth and coherence.

Yes. Historically, solid wood in a curved shape is favored for acoustic musical instruments (consider a violin or a piano), but not for loudspeakers due to the higher cost and the resonant characteristics of solid wood, which can diminish the imaging and reduce the quality of the soundstage with excessive resonant delays.

However, using conventional box designs for loudspeaker cabinets also creates a host of additional problems including increased diffraction losses, internal standing waves from parallel lines inside the cabinet (creating problems with box re-radiation and uneven power delivery at the driver) and decreased cabinet strength (exacerbated by the conventional use of fiberboard / particleboard in the cabinets). These compromises require the adoption of more complicated crossover circuitry (which can discolor the sound and create delays) as well as requiring increased internal bracing and damping in an attempt to become more inert and compensate for the inferior cabinet shape and strength.

Rather than building speakers that use particle-board and more complex circuitry, as conventional loudspeaker design dictates, the Vienna Series embraces a historical approach to sound propagation whereby loudspeakers avoid diffraction losses and standing waves by design and resonate slightly to enhance the natural tones within the frequency response of the system, just as an acoustic instrument does. Unlike conventional loudspeaker designs that pursue theoretical inertness (which is ultimately impossible to achieve), the Vienna Series are designed to reproduce sound with the most natural tone and timbre and without avoidable losses from diffraction or standing waves within the box.

As a further benefit, the slight resonant delays from the spherical and conical cabinets (when occurring equally at 360 degrees propagated at variable speeds along the natural grains of the wood) constructively shapes the phase of the signal and expands the perceived soundstage slightly (a process we call “analogue phase shaping through constructive resonant distortion”*), creating a slightly broader and more immersive soundstage that is individually voiced and damped to avoid unduly blurring the resolution of the audio image with excessive delays (beyond 1ms). (*- Patent Pending)

Another benefit of the conical or spherical design of solid wood cabinets (beyond resonant phase shaping, reduced diffraction loss and the elimination of standing waves) is the superior strength of the loudspeakers compared to conventional box designs, making the Vienna Series both superior sounding and significantly stronger and more durable over a lifetime of enjoyment. Rather than relying on the engineers or influencers to tell us if something is good, we are a company of musical creatives who take our guidance from the jazz legend Duke Ellington who famously recognized: “If it sounds good, it is good”.

Yes. Historically, wood is favored as a material for musical instruments because of its superior acoustic characteristics, including faster – yet variable – sound propagation speeds along the grains of the wood (and slower propagation speeds across the grains of wood) resulting with more stable internal vibrations (less internal loss), reduced standing waves, reduced resonant points, and a more equalized overall sound pressure response. Importantly, these principles are applicable to loudspeaker drivers and can result in a uniquely natural sound when thoughtfully implemented.
