@pauly,
"It’s not simply a case of choosing a speaker with a high efficiency rating. You need to choose a speaker with a very benign impedance curve. IOW, don’t buy anything with multiple drivers. The more drivers, the less appropriate the speaker is for tube amplification."
In general that advice has some merit but not as a blanket statement.
I was able to drive a friend’s Tekton Double Impact quite effortlessly with my 8 watt SET amplifier. The speakers are a nominal 4 ohm load and I suspect that the impedance curve is pretty flat and avoids steep and challenging phase angles.
I agree with @searchingforthesound, Tekton is a solid value/sounding speaker. It is not junk nor in my opinion is it a world beater. At their cost point they are very competent and competitive. My friend subsequently replaced his Double Impacts with Omega Audio speakers (Ironically a single driver speaker) which he feels sound better. But my point is the multi-driver Tekton was not a hindrance for low power tube amplifiers. Horses for courses.
