Audiopoli R&D
Would you like to design Audiopoli's next speaker-building project? Or build an entirely new kind of audio device? Audiopoli can offer you the advice of a hobbyist community, tools to work with, and financial support for buying components. Depening on the work, the result may be used for association activities, or be purchased for personal use. Come and present your idea at the next board meeting, or send a message in the Telegram group!
R&D activities consist of the association’s own audio engineering designs and experiments. Some of these are one-time special projects, while others are prototypes for future speaker projects. Notable projects include the Kinopoli subwoofer and main speakers.
This page compiles project reports and stories.
Timeline
- Early 2000s: Kinopoli's first main speakers, the "Cows", were built.
- 2008: the TEH Subi, Kinopoli's subwoofer of over 1,500 litres, was built in April over a single weekend.
- 2009–2010: design and prototypes of the Anni bass stands. The stands were shown at the hi-fi show in 2010, but the project stopped when the driver was discontinued.
- 2011–2012: the NuCau, Kinopoli's new main speakers, was designed and built. The speakers were presented at HifiExpo in November 2012.
- 2015: a new centre speaker built on the NuCau principle was made for Kinopoli when the theatre's sound system was upgraded to Dolby Atmos.
- 2018–2019: ReFi (Refrigerated Fidelity), a demonstration speaker built out of an old refrigerator, and its upgrade.
- 2020: the Anni prototypes, experiments towards a bigger successor to the Aniversario.
- 2021–2022: PA speakers, built together with AaltoDJ: two 12-inch tops with horn tweeters and two 15-inch subwoofers, all in paraflex enclosures. The speakers are passive and run from a rack of their own, where a DSP handles the crossovers and every driver has its own amplifier channel.
- 2023: in Kinopoli's renovation the NuCau's crossover was redesigned from scratch and the bass system was replaced with Subi 4.0.
