Finally finally, I got both speakers hooked up, I didn't bother to put 'spikes' on the speakers because I was just going to listen briefly to make sure that everything sound 'alright' before I ship it home.
As it turned out, not only did everything sounded 'alright', the damned thing sounded "BRILLIANT"!!!!!

The open-baffle sounded very very similar to the HT3, granted, the bass doesn't go as low as the 10" TC Sound woofer of the HT3, but I'm not a bass-guy, when I play my favourite Jazz/Vocal/classical, the open-baffle sounded every bit just as good as the HT3. There's a little bit more 'ambience' due to the reflection off the front wall from the midrange driver, the image is more 'diffused' and 3D, as a result the location of each instrument is not as precise as the HT3 - this is a trade-off that potential buyers have to consider before making the final decision.
All in all, I really like the open baffle, I thank Jim for creating such a wonder speakers. Fsimms is coming right now to take a listen, he is a better writer than me, so I'll get him to share his opinion too.
