Should I recap my speakers? If so who can do it?

Recapping is very important , but to redriving   is more

@bache     why are you recommending that jamesfokes replace the drivers in his Mirage.  You know that would require an new crossover design.  Or does james have a defective driver and I missed it?  

@timlub   Yes , the replaced drivers for better quality and made new
crossover can significantly improve the sound

And just how is someone who barely knows which end of soldering iron to hold supposed to ascertain all the parameters which go into making a functional crossover?

For all but the most basic cookbook crossover, which has an extremely slim chance of being correct for the drivers, it takes sophisticated equipment, knowledge and experience to be successful.

Comments like the above are the reason there are so many egregiously awful designs extant. Designing a decent loudspeaker is many times more difficult than designing decent electronics.

I agree with you jeales.  Suggesting new drivers to a guy who wants a recap makes no sense... Also,   these speakers crossovers are more complicated than most already.  To make parts changes is really suggesting a totally new speaker.
