Hello,

I bought the following 4inch driver offered in Amazon US, and would like to know if you have the Thiele-Small (loudspeaker parameters) of that reference.

Description: DROK 4 Inches 4 Ohm Audio Speakers, 40W Anti-Magnetic Car Stereo Speakers, 87dB Thumping Bass Loudspeaker Woofer for 2.0 2.1 Home Stereo DIY

Here there’s a datasheet with the parameters I need from another manufacturer as an example: http://www.madisoundspeakerstore.com/pdf/TA6FD00_04.pdf

Thank you!
