A duck.
I use it on all the forums now.
It harks back to a small spat I had on the Wigwam forum.
I'd just bought meself a pair of re-juved Bowers Active One speakers.
Lovely they were, and I said as much.
This old duffer then posted how he remembered them and how the bextrene mid/bass cones had a severe quacky colouration. He just wouldn't let up ... on & on.
The speakers sounded great of course - it was one of those cases that Marco knows so well where modern supporting kit really shows the best in old designs and old "flaws" just disappear.
Ducks go quack, too, so I just posted up the pic on the thread and we had a laugh about it and agreed to differ. I invited him round to listen for himself, he doesn't live too far away, but he didn't, of course, as he knew better!

And anyway, I like ducks
