Well, I have had the UFW-10 for 10 days now and thought it is time I shared my experience of this GREAT sub with forum members. When Sean Parque of AV123 asked me to be patient for the 240V amps and that I will not regret the wait, I placed my trust in him. Suffice it to say I do not regret it one iota. The UFW-10 is stunning to look at in flesh than in pictures. The build quality is excellent. I have seen subs with price tags in excess of £1,000 that do not have the same build quality as the UFW-10. And that is no exaggeration. After placing it in the corner (home of my old Rel Q201e) I started to put it through its paces. First test was with music using Usher's Confessions album which has some heavy bass tunes. The first words that sprung to mind was "Wow this is what is called bass." The bass was so tight, pleasantly clean and sweet it brought a big grin to my face. I found myself changing cd after cd and not feeling fatigued with the listening experience. Gain is set at half, Phase at 12 o'clock and crossed over at 80Hz. Next day, I tried a dvd. The Lord of the Ring's Return of the King. Chapter 37 - scene of the oliphants thundering on the battlefield, was AWESOME. The slam was unbelieveable. I was truely amazed at the bass emanating from this little sub. The UFW-10 is partnered by JMlab's Cobalt 816S floorstanders driven by a David Hafler Power amp, HK's 507LE AV receiver driving the centre and rear speakers - all JMLab's Cobalt Ss. I am truly impressed and very happy with the sub . The sound is FANTASTIC both with music and movies. Steve.
