I have spica angelus speakers, how do I know when the cross over needs rebuilding?

My spicas sound a little dull. I was wondering if the cross over is the cause. How do I check? They are large and it's cumbersome to take to a repair shop. I,m not sure if it's the speaker, my hearing or the fact I have single driver speakers in my other system. Thanks for your thoughts.

John used an Audax  HD12.9D25HR on that speaker.   I don't recall this tweeter using Ferro fluid. Audax still stocks the replacement coils. You can try Madisound,  they don't list it, but they may have it,  Falcon Acoustics in the UK list that they stock it... Then last resort is Audax.com 
As far as the crossover,  Johns parts were average to good for the day,  He used decent coils,  nice resistors for the time.  This crossover used 1 electrolytic and several mylars... A cap replacement isn't too tough and you'd hear it.
