CECAA850 Posted May 21, 2014 Share Posted May 21, 2014 I wonder what the frequency range is on that? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted May 21, 2014 Share Posted May 21, 2014 Looks like 32 to 6K Hz. Not bad for a single driver horn from the 20's. http://blog.sciencemuseum.org.uk/insight/2014/04/24/in-search-of-perfect-sound-introducing-britains-largest-horn-loudspeaker/ Quote Link to comment Share on other sites More sharing options...
ChuckAb3 Posted May 21, 2014 Share Posted May 21, 2014 The young man said "we were more enveloped by the sound." Indeed!! The horn is still the best way of delivering sound and the dynamics that go with. Quote Link to comment Share on other sites More sharing options...

seti Posted May 23, 2014 Share Posted May 23, 2014 The WE555 without crossover 90hz-6khz. I recently got to hear two of these field coils on a 16A horn. It is amazing how good they sound even with limited range. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted May 23, 2014 Moderators Share Posted May 23, 2014 Huge, would be coo to hear it . Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted May 23, 2014 Share Posted May 23, 2014 (edited) A K55V driver would sound very similar in the horn since it gets down below 100 hz. to 6 Khz. It was acautally patterned after the original Western Electric 555 driver, which Jim Hunter said was amazingly good. Pretty much all the good audio stuff was done before World War II.

Daan Posted May 23, 2014 Share Posted May 23, 2014 WOW... amazing. I just send the link to some of my fellow horn-enthousiasts over here in The Netherlands. Quote Link to comment Share on other sites More sharing options...
WMcD Posted May 31, 2014 Share Posted May 31, 2014 (edited) I looked at some numbers. Fc is 29 Hz, by my calculations (which I hope are correct). So the Denman horn would work well down to 1.4 of that or 40 Hz. If the mouth were round, the circumference would be 301 inches. That wavelength equates to 44 Hz. As a rule of thumb, the mouth area is a good load for the horn when that number matches fc. But it gets a bit smaller in half space -- and arguably that is the situation in the museum building. Therefore, in my view, Mr. Denman did a very, very good job. WMcD Edited May 31, 2014 by William F. Gil McDermott Quote Link to comment Share on other sites More sharing options...

When did you build those quarter pies sorry you opened up way to wide for that one Claude LOL. The math was based on stuff that has been known since then. Even though I tried to do it differently, the Hornresp software brought me back to a slightly smaller version of the Klipsch MWMs core, by PWK and Gary Gillum. I just made the horn shorter with one less fold to fit in the corner. No big deal, just good use of spare plywood.
