Hi all.
This is a very simple mod for your 325i.
Reversible within 1 second flat.
Total cost: about $2.
I got the idea from a mod on my turntable. It has a heavy metal platter. The mod is that you put a heavy, tight elastic band around the rim to dampen vibrations in the metal.
Well, I guess you already get a feeling where this is going.
I got myself some plumbing materials and got to work.
I think the pictures speak for them selves.
A pvc joint used to join two lengths of 50mm pvc.
Inside on both ends is a rubber ring.
I want just the ring
The ring diameter is 48 mm, inside.
Fit the ring around the driver house. It takes some doing, the ring fits very tightly.
The visual end result: you hardly notice the ring sitting on the rim of the driver house.
The effect I hear on sound: All sloppiness seems gone, especially from the bass department. The sound is slightly more punchy, detailed and dynamic in the lower regions than it already was. Deepest bass has a little more body. It is most noticable on percussion. I noticed the effect on the kick-drum in Joan Armatrading’s “Me, myself, I”. This drum can sound very sloppy and loose. It is more tight now.
Maybe there are other differences that I have missed so far. But I thought it was already enough to let you all know about it so you can try for yourself.
I also tried this with 48mm rubber o-rings. They work perfectly, the only thing being that they pop off easily.
I don’t know if this will work on other Grados too, but I think it is very well possible.
Have fun trying this, and let me know what you think of it.
Kees.
EDIT:
Added these photos later. The originals got lost in the outage in 2007. These were taken after the second mod I did with these phones (search for other thread)
