I picked this up on a fleemarket a few weeks ago: a set of Wharfedale headphones with a two way speaker system.
Never seen it before
Still in the box...
even the label is still with it.
Curious how it sounds, plugged it in the amplifier when I got back home. Mmmm
Loads of bass, highs are ok...
but vocals and instruments sounded thin, very thin.
If it sounded the same 40 years ago, I now can understand why it has been boxed for almost 40 years.
Opened it up and found a simple cross-over filter:
an inductor of 3mH in series with the 'woofer' (8 ohms)
a capacitor of 47uF in series with the 'tweeter' (8 ohms)
So the cross over frequency is around 400 Hz: the region that seems to be missing.
After some tinkering around with the filter I finally completely bypassed (removed) the inductor: This improved a lot.
There is still a load of bass, but vocals and instuments sound a lot better now.
Anyone else having similar experiences?
The outer shells (the white plastic) is thin and very delicate.
Both sides cracked during operations.
