Hi, I want to rewrite my column filters. These are my columns - HERE, the following are characteristics. There are two options for processing by me and I do not know which one is correct. One is as filters only parts replaced with quality ones. The second option is to make new filters, simpler and hopefully cheaper and quality, and for this purpose the first to freak speakers and to bring someone to their measured T / S parameters and whatever else you need. And here I want your opinions and suggestions which option is more appropriate?
Here are some pictures of filters and speakers:
