D-MAN Posted February 6, 2006 Author Share Posted February 6, 2006 Armando, totally cool. Thanks for the info! As an aside, I've always liked looking at other speakers, for insight into what to do and what not to do. Designs that went extinct always did so for a reason, and some reasons are clearly worse than others, but for the most part, it's pretty clear as to why they each eventually took a dirt nap. Only one is still standing and there's a few reasons behind that, too. In the case of the L.E.E Catenary, it seems that the cost/performance ratio wasn't workable compared to its competition (basically the Klipschorn, the JBL Hartsfield, the Jensen Imperial(s), the Tannoys, the EV's, just about every cornerhorn that ever was). The size is about right, though, but a single 12" woofer that doesn't go as low is the kiss-of-death compared to a Khorn's output for the (almost) same footprint. Not too hard to guess, is it?

CaptnBob Posted July 11, 2006 Share Posted July 11, 2006 I'm up to my elbows in one of these right now. It uses a 12 Jensen woofer and 5" midrange / tweeter. The super tweeter was a Jensen RP-302, which, sadly enough, was "scavenged" before I got the speaker. The cabinet is yellow formica (!) and the crossover is leaking a nasty green fluid. I'm hoping to have this thing together in time for the St. Louis "gathering" in the beginning of August. My first impression is that it must have been a bear to build - lots of odd angles. It also uses really downscale drivers. Contemporary Jensen price lists put a total price around $70, less than half of the woofer in the Shorthorn, which appears to be its most logical competition. I haven't been able to find a price list yet. I'm guessing this example dates to the early 50s, as I haven't found any ads for it after 1955, and by then it was already being sold by National.

John Warren Posted July 11, 2006 Share Posted July 11, 2006 Here's an original in Blonde. The bass driver is a stamped Jensen 12". Quote Link to comment Share on other sites More sharing options...
ZAKO Posted July 11, 2006 Share Posted July 11, 2006 I saw one down town St Louis. Van Sikel. 40 yrs ago. Up stairs display room. Thats where I saw my first Klipschorn also. EV Patrition around corner upstaires at Aeolian. OH those were the days !!!!! Quote Link to comment Share on other sites More sharing options...
WMcD Posted July 11, 2006 Share Posted July 11, 2006 I'd like to point out that it is fun to look at alternate designs. But the designers don't find any magic. That is because we have the constraints of cabinet size, mouth size, and throat size. These are the problems in transmission line theory, which includes the terminations. The catenary function is the curve of a hanging chain (some Latin here). Roughly, if you look at the Brooklyn Bridge, the arc is somewhat a catenary (loading probably distorts it a bit). And this is close to an exponential. Consider that the BB span resembles the side of a K-400. Our bass horns are very short in comparison to the optimal; mouth sizes are suboptimal. There are notions that in a short horn, with a sub optimal mouth, we can improve response by departing from the exponential. Heck, what we have is only an approximation. I believe these notions are misplaced. The bass horns do not suffer from an inch or two along their length. Rather, we are dealing with a sub optimal situation which can't be cured by any particular structure as far as bass loading. Gi Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted July 12, 2006 Share Posted July 12, 2006 Here's an original in Blonde. The bass driver is a stamped Jensen 12". Yup, that's the one I've got. The formica has held up remarkably well. Now, all I need is that RP-302, some new condensors and a Lustron home to put it in... Quote Link to comment Share on other sites More sharing options...
D-MAN Posted July 12, 2006 Author Share Posted July 12, 2006 Originally mentioned by myself awhile back, the only other catenary horn that I know of... This one is a pi (floor/wall intersection or 1/4 space) stander. DM Quote Link to comment Share on other sites More sharing options...
khorn51 Posted March 8, 2011 Share Posted March 8, 2011 I just found out the strange corner horn i found last sumer is one of theses. It does have a nice smothe sound with much lower bass than a short horn that was paired with it. cool to finnaly find out what it is.

seti Posted May 7, 2012 Share Posted May 7, 2012 I think it is a catenoid speaker but not "the catenoid"? It looks like someone monkey'd with it. Is it just me? Quote Link to comment Share on other sites More sharing options...

I don't know a thing about the Lee Catenoid, but the ones on eBay were made with parts from a Fisher console (Jensen speakers)... Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted May 30, 2012 Share Posted May 30, 2012 Both sets of speakers appear to be the same pair, same picture even - they just got moved from Chattanooga to Cincinnati. Odd choice of tweeters - the ones I've seen had a single Jensen RP-302, but these may have been built when the company was running low on funds. I've also seen a pair of LEEs on ebay that used Bozak woofers in an infinite baffle with some kind of Jensen midrange (I think.) It seems the big mistake they made was ignoring PWK's dictum "The music lives in the midrange." The Catenoids I've seen all had a real downscale Jensen cone midrange - except for that one mentioned above with a JBL in it. L. E. E. lasted a long time - most of the fifties.

Klipschfoot Posted September 24, 2012 Share Posted September 24, 2012 Well, I HAVE a LEE Catenoid! This was home made by the father of a customer of mine. This must be a museum piece. Got a museum? I must say, I was totally surprised at how good this sounds from my Marantz 2226B on MONO. I have not even put it in a corner yet. Quote Link to comment Share on other sites More sharing options...
