Budget American made speakers?

Check out the Ascend Acoustics Sierra 1. An actual bookshelf speaker that falls within your budget. Uses the same tweeter that Spendor has used in some $3K speakers.

If you’re willing to buy used, consider the Vandersteen VLRs. With a bit of patience, you should be able to pick up a lightly used pair for $1K. Someone here recently got a pair for less than $800.

Schiit Audio allegedly sources most of their parts in the U.S. Definitely consider them for amplification.

Omega builds s very good quality speaker high efficiency 
Starting around a grand. Parts express build your own kit.

I second the vote on Ascends . I have the Sierra 2's as my surrounds. Made in Southern California

Used Merlin TSM. Wish I would have kept mine. I had the Sphinx as well, didn’t care for it too much.
