Convert pa or hi fi speakers into studio monitors?

Hi, first poster here and this is an awesome forum. Thank you for such a nice resource! I need some new main speakers as I move into a new space. And I want to soffit mount them. The thing is that main full range speakers are WAY out of my budget.. :cry: So I am wondering if it is possible to make a good (partly)diy solution. Like transforming some cheaper hi fi or pa monitors into flat response studio monitors? What would I have to do? Or is it better to just build them from the ground if I`m going this route? I can`t find to information on this and hope someone can help me. Or have a better suggestion. Peace Johnny

I understand that these forums are not highly active(based on views). Anyway. I am new at the concept of building a speaker and understand that my question was not specific enough. Sorry for that.. More research will be done before asking more questions! -J
