BEC Posted December 7, 2008 Share Posted December 7, 2008 You can use the Selenium D250-X as long as you can get away with a crossover point to the tweeter of about 4000 hz. It's output falls off rapidly above that frequency. Bob Crites Quote Link to comment Share on other sites More sharing options...
tommyboy Posted December 7, 2008 Share Posted December 7, 2008 Absolutely stunning work! I sure wish I had some kind of wood working skills. I'm sure they sound just as good as they look! Great job man[Y] Quote Link to comment Share on other sites More sharing options...

IB Slammin Posted December 7, 2008 Share Posted December 7, 2008 Hover, I am a fan of the Klipsch Cornwall reflex bin. Crossed at 400hz with a big mid horn, and a nice network, it is my cup of tea. So much so that I run the Cornscala's with double 15" drivers. (dbb's) Your work with the Cornscala concept (those box's are so beautiful) and your trachorn (build quility) is outstanding. Great Job! But sir, with all due respect, how do you get a 104db speaker with a single 15"woofer from a (+/- ) Cornwall clone bass reflex bin? How did you measure that?

Guest David H Posted December 7, 2008 Share Posted December 7, 2008 But sir, with all due respect, how do you get a 104db speaker with a single 15"woofer from a (+/- ) Cornwall clone bass reflex bin? How did you measure that? I dont have any accurate measurements per say, but if a 96db K-33 in a cornwall bass bin measured by klipsch produces 98.5db from a Cornwall, then I have to assume the box gain below 400hz is approximately 2.5db. So I figure a 101.6db with an additional 5.6db over the K33 works out to about 104.1db, in the same bass bin. I tested this using an type AA crossover. and made measurement with a Behringer ultracurve to verify. you can view the measurements earlier in this thread. If I am incorrect, it won't be the first time. Quote Link to comment Share on other sites More sharing options...
