Massive upvote to @danager - The Lii Audio F15 is worthy of in-depth consideration. I ordered an F15 pair directly from the manufacturer. Got em on sale for $399...that is still the price on the site. This gives you plenty of leftover money to build your own baffles or have a woodworker crank some out.
My living room is 14x16 and these drivers fill the space with the most detailed and airy soundstage. When I listen to An American Place, performed by the London Symphony Orchestra, I can hear every instrument in its own space. Runs by the flute section move left to right and back across the right half the room. Timpani and gong hits come from a place deep in the concert hall....it’s almost like a massive worm hole opens up behind these drivers and the sound is transported directly from the Barbican Centre in London. Vocals, guitars, drums, modern, old, etc....everything I put through these gems transports me to the time and place of the recording.
Lii Audio sent me a complementary F6 pair as a gift for dealing with supply chain delays. For kicks, I set them up as a center channel...I might be onto something.
You can order the drivers directly from Lii Audio and baffles from Caintuck. Decware sells finished versions of this speaker starting at $3,400...the diy route will allow you to have a 3k+ speaker for close to your 1k budget.
Also, you can do what I did...just order the drivers to start. Rig them up to listening height and just see what happens. I put mine on a couple dining room chairs and propped them up with some books. Took a little tweaking, but the sweet spot wasn't hard to find. If you like them, move forward with the diy. If you are instantly captivated, sell them. Hell, I’d probably buy them from you for the right price ;)
Good luck
PS don’t listen to the full range driver haters. Most of em can’t even hear the hertz that are missing. I’ll gladly sacrifice all my dog whistle recordings to have highs and lows emanate from the same place.
