I have a pair of 18 inch TC Sounds LMS Ultra 5400. Who has designs for them? Push-pull, bandpass etc.

The TH 112 has been around for awhile. It goes a little lower in frequency response than the TH 115 but not as much output. It has never been too popular an item in the Danley line, but I guess there's an app for everything.

Looks like the TH-112 goes back to 2005

shello79, I think there is some hesitation to start diagramming and modeling a horn that is too close to the "real" Danley TH118. xoc1's current design is a good performer and he has all the plans and cut sheets need to build one if you are so inclined. And there's enough anecdotal information on this thread to take the design in the direction of making a *ahem* copy if you are so inclined to do so on your own.

I wonder, how close are the designs? I see the outside size is the same, and I've seen how close the wireframe models are, and I recall reading somewhere in this thread that Danley uses B&C. But even so... I've looked at the sensitivity ratings, and the TH 118 has 108dB @ 2W with -3dB at 40Hz.

I've run most the designs in here through hornresp as best I could, along with a few of my own attempts at a design, and the best I could do was 105dB.

(for example: B&C 18SW115 in a 330l horn - 4.0Volts in 8Ohm nominal, 105dB)

Where does Danley manage to double the efficiency? Or is HR somehow not accounting for something? Because 3dB is a lot of gain.
