Some drivers it makes no difference.

On my Fostex FE206E's it makes an easily noticable difference on the plus lead -

Sounds much more clear - at a slight loss of (not sure how to describe) depth(?).

I understand that some manufacturers have provided ground leads to the driver basket in some of their models, and that this used to be done a good bit years ago, particularly with 6" and 8" full range drivers.

Any idea what is going on here? or other comments?

 How do you think this may work on a lesser driver? - Audiopolous 06:50:55 08/23/03 (3)
 It may work well - it may not work at all - Triodeuser 08:51:24 08/23/03 (2)
 I tried it and... - Audiopolous 16:54:09 08/23/03 (1)

 You might want to try taking that basket gound wire to the + lead ( or - ) - Triodeuser 19:10:49 08/20/03 (0)

I would assume that you would be better off to do this with an amp with an unbalanced output using the negative lead, as this is the signal ground. If you have an amp with a balanced output stage, you would probably want to run a separate ground lead to the chassis of the amp.

We had a session in Asheville sunday at Steve B's house and tried it on his TADS in his sierra brooks grand 32's.

Jim Dowdy, Phil Seig, Randy Carter and the crew preferred it without it. Initially, I preferred it with it, because it smoothed the TADS out to my ear. However, they heard some distortion on some passages that they didn't hear with the TADS in their normal config. And I was standing behind the horns most of the time and doing the AB switching so wasn't in position to judge - however, that is a sharp eared group of guys for sure.

The difference was noticeble - just not a preferential position in the case of the TADS.

Jack R. tried it on his Alnico Philcos with absolutely no change whatsoever.

Don't know if it will do anything on AER's. But of the folks who have tried it on Fostex - we're 2 for 2 - no one else has gotten back to me as to results - very slight difference on the - lead and noticeable difference on the + lead. I've tried to get several other Fostex users to give it a shot but no one has gotten back to me with a yea or nea.

if it's easy for you to get to, why don't you give it a try and tell me what you think?

According to the Madisound tech guy, it was something that used to be done a pretty good bit years ago, but seemed to have fallen out of favor in more recent decades

It may well be something that doesn't work very well except in isolated cases. It is one of those things that I came across that seemed to make a surprising difference. so I thought I would try to understand it better.

Tom said that this was frequently done by Japanese manuufacturers and others with 6 and 8" full rangers, before the widespread use of 2 and 3 way systems. He never mentioned field coils.

He said that he had been aware of this and had seen it a number of times in the past but had never seen anything technical about what was actually transpiring.

In my setup things are more clear.

I'm running FE206E's. The transient ability of the driver seems improved -

It is not subtle on my system.

Timbo

the big thing is to try grounding to either the + or the - lead.

To some extent, is probably affected also by how much basket to magnet contact there is.

If you do try it, please post your results.

Jack R initially said he had absolutely no differnce - knowing I was getting noticeable difference with the Fostex drivers, he soldered a very small silver wire in and got some improvement.

YMMV
