Best Speaker Choice for Pass Labs X250.5,XP10?

Since you already have the amp, tell us about the room Size

You're doing it backwards. Start with speakers.

I doubt you'd ever find one the Pass didn't work with though.

Thr reason I have done it backwards was the price I paid for the pass gear was insanely cheap. Room size 17x 18 feet, carpet flooring. I know speaker choice is personal, just was hoping for a good baseline to get me started with choosing a fine pair. Tight bass, smooth detailed tweeter, soft domes work best with me, my hearing really is geared toward the midrange.

I used a massive horn speaker with my x250 wonderful.
