knck, knock.
New on this forum and already a (simple) question. I have owned a pair of Yamaha FX-1 speakers (bought new) for thirty-eight years. In my opinion (and hearing) they sound quite nice. But yes, as an audiophile you are always working on perfecting your sound in such a way that you want the "net curtain" between reality and the installation as thin as possible. And so I had them upgraded in 2018 by a friendly relationship at Yamaha in Japan (as far as possible) by, among other things, (better) filter parts, internal cabling, etc. Everything was done neatly (the bill too!). But now it comes, when I tap the dust cover of the woofer of one of the speakers with my finger, I hear a kind of reverberation in the box very softly. The other box does not suffer from this. Swap woofers, same result. So it is not the woofers. Ask that friend that he doesn't have this when testing. Yes, of course you are listening to music and not tapping on a dust cover all the time (doesn't seem to me either). I should never have performed that action, but yes, it annoys me, and it is not immediately apparent, it gives me the idea that this reverberation influences the music scene. Of course it doesn't have to be that way, but still. Maybe one of you has an idea ....
Of course I am not working on it all the time, but the fact that various professionals have looked at it in recent times and had no idea how things could occur, well ... possibly looking at other speakers. Although I do like the directness and "live" beliefs of these "old boys" but of course there are always better ones.
I am also quite satisfied with the sound I have now, because I do go to fairs (high-end Munich and Las Vegas) and there you can of course hear and see the so-called Top of the bill, of course with a ditto price tag and I have not yet run into the tree at a garden center that has other "leaves". Because if I ever visit other audiophile friends, for a listening session and who do not have a nauseous installation (B&W 800D3, Wilson Audio, Magico M2), I still go home with a feeling of yes, I can also come along.
And to think that I started my audiophile "career" with a Philips pick-up with built-in speakers, God, I was so happy, stereo still, but as more money was saved, the pick-up was exchanged for a B&O tape recorder with built-in mixer and amplifier of about 10 watts and separate speakers of course also from B&O. Boy, another audio world just opened up for me. Then it went a little faster. From various Sony's front-end amplifiers, to Yamaha also front end, McIntosh, ML, Audio Research to the current Accuphase. The speakers have also changed over the years. from the B&O to Engasound 3KF, B&W P2 (both with plasma high from Fane) AR 10 pi, LST (both Aucoustic Research) Yamaha NS 1000, FX-3 (both I still have, also modified) to the current FX- 1. The two with plasma high were (and are) unbeatable due to the absence of mass. (whatever is said about diamonds today). Only they cannot (yet) produce that much sound pressure. And then the necessary cable work of various kinds. (Kimber, Audioquest) To give you an impression of my audio pastWim.
