Spent some time browsing the different speakers over at the celestion site e.g. https://celestion.com/product/155/neo_creamback/
And I noticed that all the frequency response charts are just about the same. Coupled with if they all had the same spec being 16ohm, 75hz, 60w, I'm wondering what else in them makes the audio difference and how is it measured so punters can determine which they'd like to use?
(I'm guessing the answer is cone shape, cone material, magnet material, magnet strength but surely of the frequency response charts are the same then it will sound the same right? )
