Once we have good stock on the tweeters again we'll work on bringing that model back, and finally offering kits and a flat pack for it.
It's designed to be a floor-standing "surround" speaker, but they still work very well as mains much like the X-SLS. The X-Omnis had a bit of a more open/expansive sound compared to the X-LS, since the woofer fires upwards, much like the older A/V-O and an N-series verizon as well, so it is similar to the Ohm Walsh speaker, but i haven't heard the Walsh model's to directly compare them.
Here's a picture of one of the older AV-123 units
