Selling a rare pair of Celestion 100 bookshelf speakers in very good condition. These are part of Celestion’s legendary SL6 lineage — including the SL6, SL600, SL6S, SL6si, SL700, SL700SE, and SL600si — and were the final model in that series. Introduced in the early 1990s at a retail price of USD $1199 per pair, these are not to be confused with the lower-tier Ditton 100.
The Celestion 100 was reviewed in the June 1992 issue of Stereophile by longtime editor John Atkinson. There’s also a Wikipedia page detailing the SL series’ history. Due to eBay policy, direct links can’t be included here, but both are easily found with a quick search.

Shipping:
Securely packed and shipped via Australia Post or tracked courier
Important: Each speaker must be packed and shipped in a separate box to ensure safe transit and stay within shipping weight limits. As a result, actual postage will be approximately twice the amount shown by the eBay postage calculator, which only accounts for a single parcel (cannot be configured otherwise). An additional invoice will be sent for this.
International shipping available — item is sold AS IS for buyers outside Australia due to transit risks and return costs. A live demo (via Zoom or Microsoft Teams) can be arranged prior to shipping. No returns or refunds will be issued if the item arrives damaged or non-functional.
