                1. Draw the primitive divided circle
                2. Scale from centre along an axis
                3. Select the boundary edges and active Smoove. Set a value for your falloff
                4. Position geometry and shade smooth

                I can't give you precise values as I didn't do it to any particular size. So you may have experiment with your falloff values using Smoove.

                        it's a profile using an elliptical shape with follow me. all native tools.

                        if you're trying to duplicate the HF drive on the speaker in your first post - Genelec uses a mathematical model to generate it, not drawing tools. when i model their speakers for recording studio designs, i use the profile and elliptical curve or the scaling method - which ever one looks "close enough" since i'm not actually making the speaker, just need it for size and rendering purposes.

                            Follow me on an ellipse will not produce the shape you want.

                                But I thought I'd try an elliptical horn rather than round. I had no idea I was opening a new can of worms

                                The worm is the native only approach. Since SU is primarily a conceptual design tool and you require some level of accuracy its supported via extensibility.

                                The core can't do it but it can be done.

                                  "Rich showed you a native way to do it."

                                  "Smoove has a falloff...."

                                  I need to go back and change my "intermediate" level of understanding to "beginner"

                                  "Smoove" is a member here? And a "falloff" is a what? Do the four images he posted suffice as a "tutorial"?

                                  Not sure why you are so rude, nobody is in owe of doing turorials for you.
                                  By the way what Rich said is more than enough, those are the only (pretty self explainatory) tools to attempt a similar shape in vanilla Sketchup.
                                  As already said, is pointless to try to model this kind of shapes using only native tools.
                                  Here's my 15 minutes draft using QFT/VT2/SubD.

                                    It was actually a very mild RE-action to being confidently assured that I'd been "shown" the way to do it already.

                                    You considered my response rude? Really? You need to get out of the house more. I absolutely take offense to being called rude when my conduct does not merit it.

                                    You have offered the initial rudeness here. Please refrain from comment in any further topics I submit.

                                        Besides all the other good solutions above, here is another very quick one:
                                        Not native but with the plugin Cruviloft you can also achieve this desired geometry with ease.
                                        With the same tool and with the same simple principle you can get even further than just to the speakers.
                                        In the middle is the circle - around it is a small number of elypses which you move (up) to your desired positions. Then you let the plugin work which generates the desired shape with the preferred segmentations and smoothing by clicking on the circle and elypses plygons in the correct order - Done!
                                        (Above a certain level of complexity it is advisable to consider plugins rather than torturing yourself with the native options - especially if you are dealing with organic shapes)

                                          Thank you HornOxx. That looks promising. I'll give it a go.
