As suggested, I have upgraded the HDT 1 to the alternative tunning. I am waiting for the extra surround to fit to the driver (held up in customs with the Taboo). I feel there is a significant improvement thus far with a better sound stage, less congestion, slightly extended bass and a reduction in some sharpness at higher frequency (a product of my bright listening room).
Easy to fit too.
Now onto the room treatments - will post progress on room treatment forum.
regards
