Speakers for a small room

I recently purchased a pair of Ascend Acoustics CBM-170 SE , and I am very happy with the sound of these speakers in my small living room. They are efficient and have great mid range and non sibilant highs.They can be purchased online for $298 a pair plus shipping and are nicely built.

No ATCs (not even the SCM7) will give their best with only 30w behind them. You'd want something closer to 90db sensitivity, I'd think. Maybe a slim floorstander would suit. I'd go to take your amp to some dealers and listen to various things with those kind of specs.

Just thought of a niche speaker that should mate excellently with your Pass amp cause they're always demo'd with low power tubes - the Living Voice Auditorium series. So musical. 94db sensitivity. Thinking like the OBX-RW and down the range. https://livingvoice.eu/en/page/products
