Celestion T530

The Celestion T530 is a floor-standing, 2-way loudspeaker from the Ipswich-based manufacturer, described in period literature as a "compound loaded 2-way system." Beyond that designation and a solid set of published specifications, documentation on this particular model is thin — it doesn't appear to have generated the kind of lengthy press coverage that some of Celestion's more famous Ditton and SL series models attracted.

What the spec sheet tells us is that the T530 was a reasonably sensitive design, rated at 89 dB for 1 watt at 1 meter, with a nominal impedance of 8 ohms. It was designed to work with amplifiers delivering between 15 and 150 watts per channel. The frequency response is quoted at 55 Hz to 22 kHz (±3 dB), with the crossover set at 3.2 kHz. Physically, it stood 890mm tall, 260mm wide, and 293mm deep — a slim tower format for its era. A period brochure spec lists sensitivity measured at 1 meter with 2.83 V input, which is consistent with the 89 dB figure.

Production years and original pricing are not documented in the materials available to the Archive. If you have a pair, or a brochure that fills in those gaps, the record would benefit from hearing from you.
