To protect the driver from debris, to tame the mid highs and higs (mostly to be able to listen also to not so good masterings without shooting mids and shrill highs) and to be more deep because I could manage to touch the driver grille with my ears.

The Dekoni pads arrived. They will fit but not perfectly since they are round...top bottom ok fit ...sides a little to big. They are deeper than original but your ear will touch top part a little. They have integrated cloth covering speaker. The sound in clear modified. All highs are damped. The...

Yes, I see that Focal put an minimal unobtrusive light and I think hard mesh right under metal grille to protect the driver. A hair that manage to go and sit over driver will cause distort this is clear. I purchased the dekoni suede pads I wait for them but only after impulse purchasing I see...

Like could we see the 109 are not completely open ...they had all the back space padded with some thin hard felt like material. They had a lot of holes covered with that very permeable membrane, starting from the membrane aluminium enclosure that had a row of perforated holes to the rim and one...

Some experimenting :) This work well...increased bass and tamed highs, but they still have all sound and clarity, they are more forgiving to ears now. The material it is a hard felt similar to the filters that marshal provide with some of their headphones, they affect just the end of high...

Take out the 2 sets of pieces and paint them black :) will loose only the white logo...or could let just that single small part goldish

Yep the pads are very fragile and hard to put on.

Nothing complicated...the mechanism consist of 2 plastic ends and between them a piece of elastic, remove 2 screws from one side of the metal piece that fix the headband, slide out the elastic part with their plastic parts out of headband, unravel the sewing of the elastic short it and sew...
