Celestion Celeste Satellit Floorstanding speakers in Hobby Hifi 6/2013

Kit without housing, price per speaker

Celeste (Italian for heavenly) was derived from the name of the chassis manufacturer "Celestion". The kit developed by Bernd Timmermanns contains a Celestion bass driver, which performed excellently in the chassis test. A Celestion CDX1-1430 tweeter with Monacor horn is used as an accompaniment. These loudspeaker chassis, developed for professional sound reinforcement (PA), then show a high efficiency for HiFi loudspeakers of 92 dB (2.83V, 1m) in the full-range Celeste. The Celeste satellite described here has 95 dB efficiency. However, its frequency response is limited: It transmits in a smaller housing from 110 Hz in the same housing as the full-range loudspeaker from 80 Hz. To achieve 95 dB (2.83V, 1m) efficiency, Bernd Timmermanns uses a 2nd order crossover (12 dB/octave slope). Parallel to the tweeter driver, a suction circuit suppresses unwanted exaggerations. The loudspeaker box can be set up as a 90-liter bass reflex box, with the two bass reflex openings at the bottom radiating diagonally towards the floor, or as a much smaller closed box, which then only transmits from 110 Hz.
