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.It 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.Seemingly twice as loud as anything else at the same power level the Vintage 30 handles massive overdrive sounds with ease. Tight bass fat mids and a smooth harmonically rich top end have made the Vintage 30 an excellent 4 x 12 loudspeaker. Of course it’s also suitable for any other cab!Chassis type                                     Pressed steelDC resistance re                              Available 7.3? or 12.9?Frequency range                              70-5000HzMagnet type                                     CeramicMagnet weight                                 50oz 1.42kgNominal diameter                            12\" 305mmNominal impedance                         Available 8? or 16?Power rating                                    60WrmsResonance frequency Fs               75HzSensitivity                                        100dBVoice coil diameter                          1.75\" 44.5mmVoice coil material                           Round copperMounting InformationCut-out diameter                              11.1\" 283mmDiameter                                          12.2\" 309mmMagnet structure diameter               6.1\" 156mmMounting slot dimensions                0.31\" 7.9mm ØMounting slot PCD                          11.7\" 297mmNumber of mounting slots               4Overall depth                                   5.3\" 135mmUnit weight                                      10.4lb 4.7kg\u003c\/p\u003e","brand":"Celestion","offers":[{"title":"Default Title","offer_id":51881593405725,"sku":"28VINTAGE30-8EF","price":247.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/2092\/9309\/files\/28VINTAGE30-8EF.jpg?v=1781673259","url":"https:\/\/scarlettmusic.com.au\/products\/celestion-t3903-classic-series-12-60w-speaker-8ohm","provider":"Scarlett Music","version":"1.0","type":"link"}
