We could then form a precise model of the vintage speaker’s characteristics and apply it to a speaker design using new materials for greater power handling.\u003c\/p\u003e\n\u003cp\u003eIt was found that Celestion’s ‘H’ magnet came closest in performance to Alnico. This was partnered with a new cone and new coil assembly employing modern materials with similar mass and physical properties to the originals, but better able to handle the extra heat generated through operating with higher power equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMagnet type Ceramic\u003c\/li\u003e\n\u003cli\u003ePower rating 60Wrms\u003c\/li\u003e\n\u003cli\u003eResonance frequency, Fs 75Hz\u003c\/li\u003e\n\u003cli\u003eSensitivity 100dB\u003c\/li\u003e\n\u003cli\u003eVoice coil diameter 1.75\", 44.5mm\u003c\/li\u003e\n\u003cli\u003eVoice coil material Round copper\u003c\/li\u003e\n\u003cli\u003eMounting Information\u003c\/li\u003e\n\u003cli\u003eCut-out diameter 11.1\", 283mm\u003c\/li\u003e\n\u003cli\u003eDiameter 12.2\", 309mm\u003c\/li\u003e\n\u003cli\u003eMagnet structure diameter 6.1\", 156mm\u003c\/li\u003e\n\u003cli\u003eMounting slot dimensions 0.31\", 7.9mm Ø\u003c\/li\u003e\n\u003cli\u003eMounting slot PCD 11.7\", 297mm\u003c\/li\u003e\n\u003cli\u003eNumber of mounting slots 4\u003c\/li\u003e\n\u003cli\u003eOverall depth 5.3\", 135mm\u003c\/li\u003e\n\u003cli\u003eUnit weight 10.4lb, 4.7kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's in the box:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Celestion Classic Series 12\" 60W Speaker 8OHM\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CELESTION","offers":[{"title":"KG Super Store","offer_id":40425167847625,"sku":"10012764","price":236.76,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0024\/9803\/5810\/files\/328eb17ac0074461a34d6243fba0ffa0.jpg?v=1744258022","url":"https:\/\/www.jbhifi.com.au\/products\/celestion-t3903-classic-series-12-60w-speaker-8ohm","provider":"JB Hi-Fi","version":"1.0","type":"link"}
