Based on the freq slopes of the drivers, I'd assume the crossover is a 2-way first order with some attenuation for the highs.

I am sure it would sound ok. My guess is eff would be 89 db for hte unit, and it should sound pretty good with a 10-20 watt tube amp.
The price including cabs is around 750 pound sterling, which is close to what, a grand here? PLus shipping?

Sounds like a good deal for someone looking for a moderately eff unit.
