hello to all,
Some time ago i became curious about earthing the loudspeakers units, as Tannoy do. Then recently i stumbled on this site:
http://pageperso.aol.fr/petoindominique/doc_htm/detail.htm
( in french) and i decided to give it a try.
After all it's cheap, and fitting it on my active Genelecs 1031 would be straightforward as there is an earthing connection in the amp at the back of the speakers. I wanted the whole thing to be retrofittable in case i didn't like it so i connected the pole pieces of both tweeter and bass/mid to a copper solid core wire coming out through one of the vents openings in the front and connected it to the earth tag of the amp at the back.
The author of the above mentioned article on the net warned that this would bring subtle changes that need some time to win you over.( he mentions 24 hrs)
Well as soon as my first speaker was done i could' nt resist palying it for a bit before tweking the second one. i could immediately tell something different was going on on the left side ( tweaked speaker) so i hurried to do the second one.
The result is my system is amazing and was immediately felt and heard.To make a visual analogy, the sound seems to come from a much darker background. It is quite a bit cleaner too. Speech and lyrics are now much more understandable. For example, i have some takes of Burhan Ocal, a turkish percussionist/singer that were made at a concert we organised 2 years ago. i surprised myself singing along with him on this intoxicating feed only that this time i was able to repeat clearly all the words- even if I don't speak turkish at all. He is accompanied at the double bass by Volker Biesenbender and it really finally blossomed.
So i started playing with records which i thought agressive or poorely mastered - and the shock went on... Sybilants under control by now, soundstage more focused, less distorsions..., Any drawbacks? Well, on some recordings the pace and rythm of the music seems a tad slower- but this could be due to the fact there is more defined bass (?)
I can only urge you to try it by yourselves, the cost could be zero if you have some solid core copperwire hanging around and if you have ported loudspeakers you could try it without having to drill anything. Just be extremely careful not to mess with the tiny leadouts wires on the tweeters.
Finally a question that puzzles me since: could it be that the copper wires i added around the speaker's front and rear magnet poles could mess with the magnetic field presented to the voice coil somewhat?
Success!
all the best
