lowther acousta's 
I thought they were great for the £400 you can get them from.
Curtailed frequency extremes definately a downside of the single driver designs, and a little bit of honking. Their immediacy, impact, and dynamics would be hard to beat at any budget though.
They were horn loaded too, with very little damping - hence the massive sound, but also some honk.
