Ed Mullen's latest work at Secrets, they just keep getting better: http://www.hometheaterhifi.com/volum...06-part-1.html Seems ok for a 12" sealed, especially with the incuded Eq package. What intrigued me about the measurements were the group delay and rolloff/transient response results (due, apparently, to the steep filtering employed to protect the driver from overexcursion), which look far more like a vented than a sealed sub (compare, for example, the same measurements from Ed's last review, the vented SVS PB12-Plus). Since these are some areas to which the "tight" sound of a sealed sub is usually attributed, and since the UFW-12 is, by all accounts, "musical", it seemed there might be other factors to "musicality". Someone posted this review on another forum, and much of the thread was spent on trying the discredit the author before it got deleted. Seems the review is ok with AV123 themselves, they link to it, with quote, right from the UFW-12 page.
