Hey rick ,
The more I read about diy speakers the more I find myself going in circles. I will try to describe my setup and what I am looking for. I have a 14 by 28 foot living room with 10 foot ceilings . I have hsu vtf15 sub that gives me all the low bass I need. I have a parasound amp 220 watts by 5. Emotiva umc200. Preamp and 70 inch tv. I currently have 5 speakers that are doing well but I want something with more clarity yet needs to be powerful enough to cleanly hit 105-110 db peaks for movies . I listen to music a couple times a month at 80-90db. So I am 90/10 movie to music. My favorite parts of movies is clear audible for soft speeking parts , the symphony scores in lord of the rings and action scenes like the the latest bond movie.
I have looked at statement speakers , fusion-12 tempest with wave guide , and er18. Mtm from Dennis Murphy . Your speakers seem.to match the er18 but with better seos drivers. For my setup will yours give the dynamics I crave at the listening levels I want ? I guess my only.concern with yours is will they be running near their peak levels a lot with no headroom ? I kind of think every speaker has a sweet spot . Do yours extend to 105 db's or are they in their comfort zone at 90 db. ?
