Hi,

does anyone have the correct Thiele and Small parameters for the JBL E145? There seem to be different figures supplied by JBL in their charts and the ones given in WinISD for example. Are there more differences than the VAS?

Regards

Peter

There are 2 versions of E145 and I do not believe the TSP are the same for both

early version

late version

Hi Jürgen,

thank you for your info! Is the only difference 8 and 16 Ohms?

Do you know The Thiele-Small Loudspeaker Database (http://www.thielesmall.com/database.asp)
with two versions of E145 or
Theile Parameters.PDF von JBL (http://www.jblproservice.com/pdf/Thiele%20Small%20Parameters/Theile%20Parameters.pdf) (July 31, 2007).

VAS = 275 l always.

This has come up a couple of times


So that means the Vas of the E145 is 427.7 liters instead of the published 274.7 liters. It makes sense since JBL likes to put this driver in a 4.0 cubic foot volume tuned to 40 Hz.
