HI ,

I need the Thiele-Small Parameters (TSP) for DROK 4.5 Inches 4 Ohm HiFi Subwoofer Speakers so I can design a speaker box for these drivers. Can you please share these so I can input the parameters into my model ?
( amazon link for the speaker : https://www.amazon.com/gp/product/B01IH80ZN8/ref=ox_sc_act_title_5?smid=AFHAE9RJVUMB&psc=1  )
I need the following:
