Best JBL driver for a HiFi 80 Hz horn

A few thoughts:
- 5:1 compression (2227) ratio can be too much (giving much stress to the cone).
- Vrc and Lrc is very small (might actually be hard to build, and higher Vrc will give better/more LF).
- Have a look at the group delay too (there's normally lots of group delay close to fc)

Another thought:
When the horn is free standing (in other words: not within a large baffle)
shouldn't be taken a room angle of 4*PI ?

The cone used in the 2227H is reinforced with fiberglass for added strength.

Most probably the reinforced cone is intended for higher compression.

The 2227H is a bit too extreme for my taste :-).

Yesterday I bought two 2202H. I am going to use these for my project. Maybe I can get another 2, using two drivers in one horn will shorten it by 35 cm.

These simulations are for a horn placed on the floor, half space (2pi). When the horns are up in the air 4pi is used.
