Need Recommendations for a pair of Speakers around $1,000

Oversized bolt-on outriggers can make any speaker very stable.

I have an inexpensive pair of speakers in the BR that have AMT tweeters. The speakers aren't great but the top end is smooth so.....

Any opinions on the Elac Carina BS243.4 which also have AMT tweeters and, on paper, a pretty good frequency range? Not sure I can listen to a pair locally but I did find a dealer who sells the Goldenear AON 2, and AON 3 speakers also with an AMT tweeter.

I appreciate the suggestions here even more because no one has anything to gain by offering an opinion.

most people recommend what they own, so there are all sorts of psychological influences that may not be as nefarious as a saleman looking for a commission… but it does not make the suggestions here automatically better.

OK, you have a fairly large room. But the main part of that equation is where will you be sitting when you are doing your listening? How far away will you be from the speakers?

Small bookshelf speakers can play loud but they’ll never sound "large" or "scale" (in general - I know there are some exceptions). But if you want scale, you should probably go with floorstanders, and even then, at $1000 for two speakers your choices will be limited.

Even in a large room if you are sitting no more than 10 feet or so away, you might get by with bookshelf speakers, and later add a subwoofer.

I note that the Polk R700 are on "sale" now as of 5-16-2022 for $899 each. Yeah, that is nearly double your budget, but in the long run you might be happier with larger speakers in that room if you can stretch your budget, plus you might not need a sub (at an extra expense) down the road.

Good luck. Oh, I looked up the Adcom GFA-545 at hifiengine. I could only find it specified to output 100W/channel at 8Ω.  Make sure it will be happy driving lower impedance speakers.  6Ω might be OK, but 4Ω (unless it is OK with that) might be harder, and many 4Ω can dip even lower at certain frequencies.

I have a few options with distance.

We have hardwood floors and our furniture sits on small pads so they can be easily moved to vacuum. I can slide the small recliner to the center of the LR anywhere from 5' - 15' from the speakers.

Otherwise the recliner built into the sectional couch is about 19' from the speakers.

The manual on the 545 states that it has the "ability to drive very low impedance loads" which isn't very specific but I don't see 4 ohms as an issue and I don't listen to music at ear bleeding levels.
