    2405 - 16 Vs 8 Ohm question

    Ok, so some JBL drivers are labled 8 Ohm and others 16 Ohms but there is little or no difference between the two.

    Are the 16 Ohm and 8 Ohm versions of the 2405 slot Alnico drivers really the same too?

    My recollection on replacing some bullet nose diaphrams a few months ago was that JBL sells both an 8 Ohm and 16 Ohm versions.

    As far as the cone speakers go there are 8 and 16 ohm models, H and J. With the ring radiators I am sure they were all 8 ohm regardless of the name plate.

    If you did a search on this question you would find about 200 posts made by me alone discussing this. I've even posted plots comparing them.

    JBL does make multiple impedance versions of many drivers, however there are a number of vintage drivers such as the 2405, LE15A, and LE85 where the impedance never changed and they were sold as either 16 ohm or 8 ohm drivers depending on the year of production.
