Hi,

Could somebody help understand /explain if the difference in the magnet structure provides better bass output as stated in the 515-8G literature (by ALTEC). It is also mentioned there, the coil is 'underhung'.

Does that mean the 515b is 'overhung' and the reason, it does mid bass well.

If there's an existing thread, a pointer would be fine. I found this article with input from GM but not specifically on being hung-up....

416's vs. 515's

Regards.
