Buying a speaker kit that you have not hear is always going to be something of a, "shot in the dark", which requires faith in the company that designed/developed the speaker on offer.
The company of which you mention, I understand, was founded in the early seventies by Malcom Jones (previously of KEF and still has an association with Falcon) . This would gain my confidence.
I have built many! speaker kit's since the seventies and have never been disappointed given the input. I believe that a successful speaker build will put a big smile on your face.
