I picked up a pair of Mordaunt Short MS40 speakers from a charity shop today. They're the old 70's/80's brown ones!
I was hoping they would sound at least half decent so I could put them into my workshop and listen to the radio, but after hooking them up to my main system I was very unimpressed with them. Just seemed to be too much treble and no warmth coming from them. All the drivers were working, so either they're supposed to sound like that or the crossovers are a bit out of whack?
I've opened them up and taken a couple of photos and made a sketch of the crossover circuit, which has lead me on to two/three questions:
Cheers
[Oh, and any help making the images smaller until they're clicked on I appreciate as well

- I'm thinking I might just add some more resistance in series with the HF as a start to see if that helps re-balance the HF with the LF. Do you think it would be worthwhile replacing the electrolytics?
- What is the value of the second cap across the HF, one is marked 1.8k, the other 1.15j (see photos).
- Clearly MS are trying to tame this tweeter esp with the caps in parallel, but two caps??? Am I missing something here??? I triple checked it and that's definitely the layout???
