115 db - sorry that is going to need a horn.

Don't think you will find a single 4 or 5 inch ribbon at 2000 hz that will put out that level of output without some horn loading.

Or at least have a good number of replacement elements on hand.

Also I could recommend some reading by John Eargle that might widen your knowledge of horn, horn geometry and distortion. Like most things in audio , its not there is a superior topology , but superior implementation of a topology.
