Those specs are not complete. If you have a set of specs you've measured on the Fane, I'd be interested to see them. The spec sheet I have for it has inconsistent numbers and gives only 91dB/1W/1m. However, a Qts of 0.4 is not that high... I would not be afraid of trying a horn design with it.
I could recommend suspension designs, but the problem is no one publishes information on them, either on the design or the performance, so it wouldn't help much. One way you could test suspension performance without sophisticated equipment is to see how resonances shifts with different drive levels. Ideally it would not shift, but typically it will rise as drive level increases as the suspension gets stiffer as it moves from rest. Good designs (well, good depending on your design goals) will not have a big change in resonance. However coil heating and rise in DCR will still change the Q...
The 6.5" I'm using is one I made. Neo magnet, vented spider, very light paper cone and a light coil. It runs about 95dB/1W/1m, Qts of 0.3, Fs around 95Hz.
