Tube amps and speaker ohms

In your opinion , do push pull amps work better with 8 ohms or 4 ohms. .I am under the impression the lower the ohms, the more power is demanded from the amp....Another question, are there low powered SET amps ,and high power SET amps?
I'm looking at a 40 watt 845 tube amp for my 8 ohm, 89 db speaker.. just cked the Thor has a 86 db W18 midwoofers(2 per cabinet) and a 88 db tweeter. Will an 845 amp rated 40 watts be able to drive the 86/88 db speaker? With authority, bass, mids, highs, in dynamic sound stage? Synergy? Or poor match?

Thought id throw this in there. Schweikert vr-8. 4 ohm with a dip at 3ohm lowend. 96 db W 1 watt. 300B X4 mono blocks 50 watts each. Clipped the dooit out of them on medium levels.
Rogue 120 monos drove the heck out of them 120 watts.

No 40 watts will not drive a 89 db speaker. Push pull or single ended. I have a speaker at 96 db and 200 watts push pull is just enough. Anything less its clippsville.

Instead of playing games why not spend 2K and pick up a pair of excellent hurricane amplifiers and put power worries to rest.
