About-us

The Diasound brand was created in 1998, comprising a partnership established between Diatone, a Japanese division of Japan’s Mitsubishi Electric Group, and Tectronic Equipment do Brasil, founded in 1990, today established as Weltmarken Elektronik.Diatone agreed to supply ultra-high fidelity loudspeaker drivers aimed at the production of high-end loudspeakers under the Diasound brand.

As an outcome of the restructuring which took place in the Mitsubishi group in 1999, Diatone’s activities were suspended in Japan and new partnerships were then negotiated with other manufacturers – especially European ones – for the development and supply of components dedicated to the production of high-end loudspeakers in Brazil, intended for export purposes mainly.

Through solid partnerships, significant financial investments and the work of highly qualified designers endowed with exceptional hearing skills, who also possessed respectable expertise in the field of electronics and electroacoustics, our loudspeakers were developed, having been  capable of pleasing the most demanding perfectionists! By honoring quality criteria in the tiniest details and refining these until exhausting all limits, Diasound equipment have attained an unimaginable level in audio fidelity!

Since it belongs to Weltmarken Elektronik, a company which has been active since 1990, and possessing lots of experience in several fields of electronics as well as considerable international business expertise, Diasound came to receive long-term financial investments, and all of its projects rely on solid partnerships established with reliable foreign suppliers. Regarding after-sales, Diasound has gathered all of the resources and technical requirements needed to offer the best possible services (i.e., a large inventory of replacement parts enables providing permanent technical assistance) while sharing Weltmarken Elektronik’s expertise in the most intricately demanding supply and maintenance agreements in other fields of electronics, especially for clients such as large banks, private and state-owned companies.

Moving beyond electronics and electroacoustics, investment was also made in R&D (research and development), for the production of loudspeaker enclosures. Unprecedented techniques have been developed in order to provide the highest quality standards for acoustic applications, finishing and durability, and these stand out among the highest ones in the world market! The development and handcrafted production of state-of-the-art loudspeaker enclosures on a commercial scale constitutes one of the toughest challenges, since it requires expertise, materials and human resources that few manufacturers in the world possess.

By honoring unprecedentedly high criteria as practiced in the high-end audio industry, the Anna System was developed, an exclusive system employing state-of-the-art active loudspeakers which competes in performance with the most renowned and sophisticated systems in the global high-end market, even in price ranges above US$ 200,000.00! The Anna System project was essential for mastering the entire technique, which also involves the other components and accessories which make up a system, such as digital and analog electronics, amplifiers and special cables. Performing as an exclusive laboratory, it came to be an indispensable tool and reference for the development of both the Summa and Simoneta loudspeakers, as well as other ongoing projects.

In addition to having become a reference, and especially an auditory one, the main legacy stemming from the Anna System was the ability to develop and refine concepts to exhaustion by consolidating all limits to absolute perfection, therefore eliminating the need for revisions and future upgrades. This is the main reason for so many years of refinement before the commercial introduction of the first Diasound loudspeaker. These criteria, besides providing exceptional fidelity, and aided by the classical design and unique finish, also give customers the needed certainty when making their purchases, at the best cost-effectiveness ratio.

Ultimately, and from its long history, unprecedented techniques and concepts, Diasound stands out as an exceptional brand, respected by the most experienced and demanding audiophiles, who are generally familiar with live music as performed in theaters and presentations!

In comparative evaluations, it is very easy to conclude that Diasound is a brand whose equipment stand among the most respected and refined within the global high-end market! These loudspeakers draw attention to themselves, and all of the attributes mentioned can be perceived very easily, especially in an audition!
