Hi Guys, I am pretty new to speakers and design...yup it's trully a healthy addiction. I've been reading it daily for the last 10 months. I have couple of questions rergarding Css Fr125 driver and available designs for this driver. Is there a monople design for this driver, a tower, ofcours? I've seen Jim Griffin bipole, was it actually designed for a single woofer? What would be dimensions for monople tower? The same as Jim Griffin design? Should a tweeter be added or CSS is sufficient? And lastly, what is the difference between FR and WR version? Thank you guys. Love reading all of your posts, very stimulating.
