OK CD2, it's time to weigh in on your own thread. We have a growing thread of tail-chasing but we don't even know the size and dimensions of the listening space where you want to install a pair of omnis.
If you have a large space get a pair of Mirage OMD-28s from Vanns.com. This is a $7500 pair of speakers available for $2800, has state-of-the-art woven fiber drivers, is linear down to the mid-20's, and the
Absolute Sound review says in part:
Many speakers claim to offer disappearing act imaging, but I think the OMD- 28s take this to a much higher level one bettered, in my experience, only by speakers such as the reference-class MBL 101 E (an omnidirectional speaker against which all others can be judged).
So even at its original price of $7500 it was considered a remarkable overachiever--compared to the multi-thousand-dollar MBLs. The reviewer bought a pair of the OMDs.
If that's too much speaker for your space, get the OMD-28's little brother, the
OMD-15, a $2500 speaker pair available new with warranty and return privileges for a mere $800. You can then get a pair of these
SVS compact powered subs in matching piano black, giving you bass extension into the 20's and coming right in at your $2K budget. These subs are small and easy to blend both sonically and visually.
Any omni needs to be out from the back wall, but I found that my OMD-15's can function quite well about 24" out from the wall. They also fill a large open-architecture living space with vaulted ceiling. The entire area is a timbre-correct sweet spot with a stable, centered soundstage.
