Floorstanders with a large sweetspot


I'm looking for a pair of floorstanders under $2.5k new or used that (1) can be placed close to a wall and (2) have a reasonably large sweetspot. I will drive then with an integrated tube amp, TBD based on the speakers. The room they will be in is 12 x 18. Any recommendations are welcome. Thanks.

Sorry, the phase cancellation from unequal path-lengths for centrally placed images (as an example) not only sound markedly different off-axis, they MEASURE differently.

IMO, having a wide spot to sit to hear centered images with their ENTIRE FREQUeNCY ENVELOPE INTACT is not possible with stereo, unless there has been a recent break-through in the Laws of Physics.

We will buy time-and-phase-aligned speakers and then sit off axis which is most certainly NOT a phase and time aligned listening position.

Doesn't mean that we can't sit off-axis and enjoy the sound, but it is important to recognize that such sound is a distorted version of the original.

Can still be great fun to listen - I do this when my wife joins me - she gets the sweet spot :)
Hornguys: Do you think speakers vary as to whether they give a more or less satisfying listening experience off axis, or are they all they same, regards the decline in litening quality as one moves from the "sweet spot"?

Looking to place the speakers about 5-10 inches from the rear wall and 1-2 feet from the side walls. As far as the sweetspot goes, I would like something more than just a single seat on a couch.

You'll do better with speakers designed for in-wall use.

Get something which has a real speaker enclosure (flexing dry wall would be bad for the sound) and run a three-way with a small midrange driver.

Triad has some nice designs and will color match the grills to the edcor.

They vary radically based on the driver sizes, locations, and cross-over points although to get those positive differences you'll need to get away from conventional cone and dome 2-ways.
My Zu Def 4s are places within 4" of the back wall and give a wide sweet spot. While they are pricey, you might call Zu to ask whether their other speakers have a similar characteristics. I also second Audio Note.
