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.

Thanks everyone. I wonder how new caps on the crossover would impact the sound? The tweeters are fine so are the woofers. Just don't sound crisp if that is an audio file term.

Just did a quick search and came across this Spica enthusiast site,  it gives you all the info that you'd ever need.
