Speakers for leading edge, transients, speed and big sound

Hello- I am looking to spend about 20-30k on used speakers ( guessing they would have been -40K new a few years back). Any suggestions welcome. I have a 14*20 room and I am looking for dynamics, potentially a great sounding horn or equivalent. Excited by Tektons but since I have the budget wondering if there's anything better. I did have the JBL M2s that I really enjoyed and Revel Salon 2s that I didn't so much

Thank you!
