Speaker recommendations

Have you considered something from the Klipsch Heritage series - many options, all of them much more inexpensive used than just about all of the above suggestions. I have the Cornwall's myself, but there are smaller sizes if you prefer or need that. And you can certainly drive horns with any amp out there.

Don't know the Alons, and Vandys might not be the easiest to place to get them to do their thing and may not be as airy sounding as some others out there. Should be a great match with the McCormack though.

Given your criteria the first thing that came to mind was Totem, but I'd also look at Audio Physics, Joseph Audio, Thiel (CS1.6 rather than 2 2), and Silverline. All have very good imaging and portrayal of air and space. Best of luck.

Audio physics and Totem are great speakers, but can tiny drivers make bass?

If you're looking in the $1000 price range I think you're going to have to make a trade-off somewhere given all your criteria. All these speakers make decent bass, but whether it's enough for you in your room is impossible to say. Best would be for you to go to some dealers and give them a listen if you have some within a reasonable distance.

Of the speakers mentioned I think the Gallo Reference 3 may give you the best shot at achieving all your goals (assuming they're in your price range), but I wasn't sure if the DNA 0.5 would be up to powering them so I didn't mention them in my post (I would think they'd at least do a decent job, but that's just a guess). Of course you can always add a separate bass amp later with these speakers if necessary, so this could be very attractive overall option (if you like the sound of course).

Of course if you really want deep bass you could consider adding a sub or two down the road to any of the above speakers. This could give you truly full range performance and has the added possiblity of customizing bass for your room with some bass management and subwoofer placement, and it opens up a lot more options for main speakers (even including monitors that can image like demons). This is actually what I'm planning to do because I've found that the foundation provided by high-quality deep bass can make everything significantly better and more enjoyable, and I don't have the dough or the space to make good full-range speakers work in my room.

Anyway, best of luck I'd be interested to know what you eventually choose.

If you have room for them, how about a pair of Cerwin-Vega CLS-215s? Check around and read the reviews, which include favorable write-ups from Absolute Sound and Soundstage.com. Designers were formerly of NHT and another audiophile spkr company. Mid and tweeter, although horn-loaded, are sourced from Scandinavian speaker companies.

About $1K/pair, measured sensitivity around 92dB, bass down to the mid-20s or lower in-room, dynamic range to (literally) beat the band, and yet the reviews indicated that they excel in microdynamics and low level detail, especially at the price and factoring in the frequency and dynamic ranges.

You want bass? Twin 15-inchers should do it. Fortunately, they cross over to the 6-1/2" midrange at a fairly low 250 Hz. That would function similarly to a minimonitor mated to a 2x15 sub, but with better integration.
