upgrading caps -- easy to do?

I just upgraded the crossover in my Kappa 9's. I replaced the caps and resistors with better quality ones. I left the inductors alone. The result is they sound a whole lot better than they use to. Well worth the effort. My advice to you is get yourself a soldering iron, solder, flux, de-soldering wick and some old junk circuit boards and learn how to solder and de-solder first before you mess with the crossovers. If you are going to do this, you might as well know what you're doing.

After you are confident in your soldering skills, then try your hand on upgrading your crossovers. A schematic would be helpful. If you need ideas as to what caps and resistors to use, talk to Jeff at www.sonicraft.com He is a cap expert and knows what he is talking about. The results in upgrading a speaker crossover can be very positive if you do it right.

I upgraded the caps in my areius a couple of years ago. I talked to a tech at martin logan and he gave me the values of the inductors and said replacing the caps would be a great idea because they could not use premium componets at that price point. All the caps were non-polar electolytics except for a 10mfd bypass on the electrostatic element. I would start by upgrading this cap. The total capac. is in the 30-35 mfd range so it isn't cheap to replace with a premium cap but the electrostatic is where you will get the most benefit. The ones on the woofer section are very large so I used solens there for cost effectiveness. If you have any questions, e-mail me

Aerius i uses Solens caps... you guys still think this might be worth upgrading?
