The design and manufacture of audio equipment, are marked by constant and indispensable values that aqua - acoustic quality pursues with dedication. aqua - acoustic quality was founded in Italy, proudly carries on musical excellence, artistic tradition, the spirit of innovation and craftsmanship of its people.
Research and Development
aqua - acoustic quality equipment is not subject to the whims of market fashion since they are build to achieve true high fidelity sound reproduction. By combining dedicated research with creative thinking, R & D Department has brought forth a range of innovation whose aim is to recreate the experience of live music in your home. Some of these:
• proprietary DFD (Direct From Decoder) digital decoding without digital filter for purest digital signal quality. Innovative treatment of the PCM digital signal: after exhaustive listening tests, a 1x sample rate has been chosen as the best.
• Exclusive high-performance digital interface AQlink (I2S protocol), uncompromising digital connection from transport unit to DAC, employs CAT6 cable can connect both RJ45 and professional etherCON RJ45
• discrete circuit with high-speed photocouplers for Galvanic and magnetic isolation
Diesis loudspeakers exude the beauty of masterful form and function. The finest materials (Clad 58 and Corian) are used consisting of anodized aluminum, stainless steel, wood and PVC. Aluminium is used to support the driver / horn (because it combines strength with lightness and ease of processing), the steel is used in both the reinforcement of the structure (for his strength) and is in the plate of two wf ( for its spring force). The wood is used in front of the speaker (either as solid or as MDF), while the PVC is used in the base of the cross-over, the thickness of the wf is in the frame and back.
Loading for bass
The charge dipole is what in our experience gives us the highest quality sound. Its merits are many. To start, it has a total lack of coloration of sound which is caused by the traditional furniture of the main loads. It has an excellent damping system (the stereo and filter are attached to it) without altering the parameters of the speaker cabinet. Not to mention the naturalness of its sound, which is due mainly to the lack of mobility and ease of issue that translates into high quality allowing it to play well with low power and low listening levels. It has excellent detail retrieval and articulation because of its small variations of the phase noise, variations that are well audible (as opposed to what you think) and facing the vast majority of speakers on the market using traditional loads.
Reply to meet some critical issues
The characteristics (do not like the load) is essentially a dipole low level and low power handling of the bass range. Through extensive research we were able to overcome the difficulties with the use of the following techniques:
The presence and level of low frequencies are obtained by combining two wf 12-inch high-efficiency filtration to a mobile differentiated by the particular form in the back that would allow to have the least possible loss of level. Using an innovative (CLAD 58) for the mobile, a conglomerate of our formulation composed of mineral dust and special resins is used in liquid form within a ‘single mold at the time of solidification ensures excellent rigidity and damping , well above the wooden furniture or the like that with their vibrations disperse much of the sound level that a dipole can return. The light on the front horn loaded wf improves the efficiency of the noise in the media and contributes to the midbass range realistic sound.
The use of a concentric compression driver allowes to obtain a single trumpet with a consistent and coherent emission from about 600 to 25,000 Hz, a result perhaps unique in the world. The shape of the trumpet and its radii allow for a carefully designed dispersion also excellent off-axis response and a regular speaker. Impute to them the filter cross-over with the minimum number of components in series has now become possible and thus have a realistic and natural sound with minimum phase shift.
The fixing of woofer
The current trend is to increase the number of anchor points of the speakers (especially those of low frequencies) for additional strength in coupling between the vibrating element (speaker) and the material on which it is attached. In our speaker system Total Fix-wf stipulates that the two are trapped in a shoal of the structure and then are locked (with the interposition of a thick PVC) from a single steel plate from 20 / 10 through nine fixed bolts M8 screwed into the same sockets drowned in Clad 58. The plate (covered with a layer of vinyl) then pushes with its great elastic strength over the entire surface of the flange of the speaker to ensure good contact between the parties.
Crossover of the media and the quality of components
The cross-over was created from two separate bases, one for wf and one for the trumpet. The masses are completely separate in order to take advantage of the bi-wiring and bi-amping. These supports are made of PVC by a ten millimeter thick machine with numerical control to take advantage of the wires connecting wiring cables to the speakers, which nullify the contact resistance of the traditional bases in vetronite to create a better signal transfer . The components of the cross-over are of the finest German production (Intertechnik and Mundorf) and have been carefully selected with many listening tests because it will provide the shortest possible signal degradation.
In particular, have been chosen as the speakers in series, or series capacitors and resistors to coal Mundorf Silver-gold in the medium and tweeter voice coil in copper foil Mundorf OFC in series with the woofer above.
The Diesis Aura is a new speaker from Diesis that inherits all of the technological innovations from the Caput Mundi model in a cabinet whose weight and dimensions are reduced in order to make it capable in smaller spaces of holding up the standards of the flagship Diesis speakers. The exponential horn is made of ABS and fiberglass to all for excellent sound diffusion. The best components are used thorough, such as the Mundorf silver gold condenser.
In the Caput Mundi for the first time in the world we combined a dipole load for the low frequencies with a coaxial compression driver horn loaded for the medium and high frequencies.
The variety of finishes offer the possibility to modify it easily over time, allowing the Caput Mundi to be perfectly inserted into any environment, for the pleasure of all. The handcrafting of the construction is merged with the design, creating a sought-after object that is extremely exclusive and can be personalized with various colors and finish. The use of innovative materials (CLAD 58 and CORIAN), here used for the first time in an audio system and the optimization of the parameters of the project, exalting the advantages of the technologies used (dipolar load and coaxial transducers horn loaded), for a result that is dynamic, transparent, articulated, coherent, natural, life like and with total absence of listening fatigue that has left more than one listener stupefied.
At a time characterized by carelessness, by appearing rather than being, in which the cost of things is determined largely by added values, where advertising counts more then the quality of products, we felt the need to take a step backwards to construct something genuine, leading to the rediscovery of artisan production.

Advantages of NuPrime Amplifier Technology
1. High bandwidth. Truly faithful reproduction of music demands bandwidth, and plenty of it. Inadequate bandwidth withholds important spatial information and tonal complexities. NuPrime amps deliver high bandwidth with a ruler-flat response from 20 to 50,000Hz. Only a very few, very expensive linear amplifiers are capable of achieving that. This bandwidth allows NuPrime to amplify complex music with faithfulness far beyond the capability of conventional amps, with particular regard to a vast soundstage – accurate spatial information delivered in full.
2. An extremely high damping factor. Damping factor is simply a measure of an amplifier’s ability to drive and control a speaker. The higher the number, the better. An excellent tube amplifier might have a damping factor between 10 and 100. A high-quality Class-A amplifier might reach 200. A NuPrime amplifier has a damping factor of about 400. And unlike conventional amps, NuPrime’s damping factor is totally unaffected by changes in audio frequencies. Simply stated, NuPrime delivers lightning-fast dynamics to any speaker.
3. Ultra-low distortion and noise. In conventional amplifiers, fixed specifications for distortion and noise simply do not exist. Manufacturers invariably choose to quote the most flattering numbers, typically measured at 1 watt. In reality, when power demands increase, so does distortion and noise. NuPrime employs patent-pending technologies that cancel distortion at every cycle of operation. NuPrime amps maintain the same low distortion characteristics at every output level and audio frequency.
4. No phase shift. Many amps use output filters that create phase shift. When phase shifts, spatial information becomes inaccurate. Most amps present phase shifts of better than 45 degrees at 20 kHz, heading toward 90 degrees as frequency increases. NuPrime amps cancel these distortions owing to a unique closed-loop design producing zero phase shift across all frequencies. Repeat, zero.
NuPrime provides unequalled, fully regulated output without ripple voltage or noise. Absent this electronic smog, music emerges from a pristine background, delicate details and nuances intact. Purity has a sound, and it’s beautiful.
NuPrime’s sonic character stands well apart from – and indeed above – the soft, cushy sound we often associate with most tubed amplification or the dry, edgy sound we often associate with solid-state and switching technology. Rarely does an amp achieve an ideal balance of richly textured timbres and harmonics, bottom-end authority, startling dynamics, exquisite low-level detail, and a fully revealed, fully dimensional soundstage against a backdrop of mile-deep silence.
Alta Audio’s loudspeakers are the culmination of over 30 years of experience designing, building, and audiophile-class listening in the high end loudspeaker industry. Our designer has one goal in mind throughout the design process: getting the best and clearest sound reproduction of live music. Holding to this standard, we have developed new technologies allowing us to create a truly superior modern loudspeaker.
As a designer, you try to design a cabinet that doesn’t resonate. Resonances locate your speaker in space, causing you to hear the speaker and its location in the room rather than the music itself. Standard design strategies involve putting heavy padding material inside the cabinet to dampen unwanted resonances. Excessive internal dampening causes the lower frequencies to become muddy and distorted, giving a booming, humming quality to the sound that removes the clarity of the bass. When you have excessive dampening material, you’re hearing the padding instead of the music.
Alta’s solution to this is our proprietary material DampHard: a multi-layered, multi-density material that makes up the walls of all our high-end speaker cabinets. Where standard MDF or other materials would allow certain frequencies to resonate the cabinet, DampHard remains dead to virtually all vibration. This allows us to heavily cut down on a cabinet’s internal padding, maintaining the clarity of the bass.
Coupled with our Alta XTL technology, DampHard allows us to create a truly superior cabinet that acts like a musical instrument, extending the range and clarity of the bass, while keeping the cabinet resonance-free. This combination in all our high-end speaker models creates an unparalleled bass response complete with all the clarity and dimensionality of the music.
With more than 4 decades of experience listening to and comparing high-end audio components, Jeff Wells learned that he has a special talent for evaluating and identifying those characteristics that make equipment special.
