Welcome to AC!
We've definitely got a few DIY floor standing kits that are fantastic options, if thats what you're looking for.
If you want full range, your best bet will be the X-MTMs
If you want a more open mid-range, then I'd looks at the X-Statiks.
Want something a little more simple? Then there's the X-SLS Encore that is the floor standing version of the X-LS Encore bookshelf.
Then off the beaten path there's the X-Omni that's got a really unique sound to them, but they definitely need to be pulled away from any walls.
Then of course, there's the high end open-baffle offerings like the NX Otica. Just make sure you can get them 3+ feet into the room.
Beyond that, I'm sure there are a lot of fantastic options, but most available options will definitely be average at best, despite their pretty looks..
Just depends on what you're looking for?
