Restoring a CELESTION DITTON 66
The Celestion Ditton 66 Studio Monitor stands as a flagship of 1970s British high-fidelity engineering. Renowned for its effortless authority and warm, detailed soundstage, this iconic floorstander features a four-driver layout. High frequencies are handled by the prized HF2000 dome tweeter, paired with an MD500 dome midrange for rich vocal clarity. Its defining feature is low-end performance: a 12-inch active woofer coupled with a 12-inch Auxiliary Bass Radiator (ABR) passive cone, delivering deep, resonant bass down to 18Hz without dynamic compression. An audiophile classic built to last.
