personaly I wouldnt look at any thiel especially any models with the cast baffles
1: to easy to crack the baffle
2: out of business and may be difficult to repair
3, very out of date design compared to modern designs
if you are looking for a large dynamic loudspeaker look at a pair of legacy focus
and if you add a wavelet processor you will gain electronic phase and time correction along with room correction and eq.
