Of all the loudspeakers comprising the Klipsch THX Ultra2 system, the subs were the biggest surprise of all. They look so utterly civilized , yet when called to duty they can kick & roar with masterful authority. As capable as they are at dumping eye-popping amounts of acoustical energy into a listening space, they don't overwhelm or overplay as some subs tend to do. They don't butt in to audio scenes where they don't belong. They integrate seamlessly with the rest of the system and having two cabinets helps immensely when it comes to finding suitable placement when dealing with room modes.

Klipsch opted to build the power amp separate from the subwoofer cabinet; the amp is a stand alone unit that jacks into the subs via the supplied 6m (20') long, Neutrik Speakon plug tipped, cables (See Figure 5b).

Providing a separate power amp is a major convenience, and especially helpful for those who opt to build their system into the walls of their home theatre. Even if you have no plans to build your speakers into or onto the walls of your home theater, racking up the KA-1000 along your AV receiver provides other benefits: If you've spent too much time crawling around behind your sub tweaking this or that setting, perhaps by flashlight, you'll especially appreciate having the sub's power amp close at hand. No more hanging out behind your sub in that forgotten zone where dust, lost toys and the occasional house pet gather while you tweak away in search of the perfect splice.
