I personally haven't heard of Andrian Audio before, but the A100.neo looks interesting as does the A130. Although the AVI puts the frequency response at a 100Hz and up, I think you'd have a difficult time reproducing such low frequencies smoothly. Personally, I'd say you're better off with a larger driver. Don't get me wrong, they go low... but they have their limits. Even my dome midrange is bigger that the FRM's.
My FRM's are actually 8ohm drivers as I was going to pair them up - two on each side in parallel.
I'm willing to take offers on them. PM to discuss price.
