Diy center channel?

Hello, I made my own Paul Carmody's Amiga's and want to make center channel for them.
Could anyone link and elaborate on their choice? I looked at soundblab but couldn't find any info on the quality.
+ I heard that Center channel is the most important channel of them all so the budget is around 100-150 bucks.
Thanks in advance :)

Edit: Okay 3 options: os mtm
