Recommendations for best most efficient speakers


Perhaps it is a misnomer, but tubes require very efficient speakers. Since I love tube integrateds, I am looking for recommendations on the best, most efficient hi-fi speakers available for someone on a mid-fi budget. I am looking for sensitivity ratings >= 94DB. I have found a few, but they are cost prohibitive.

Thanks in advance for you help..

Thank you Audiokinesis for the clarification. It seems logical and I am really tempted to test the waters a bit more before diving into loudspeakers.
never use 'efficiency' as the most important determining factor selecting loudspeakers, unless things like 'sound' are indeed less important. klipsch heritige and coincident are great, and happen to be efficient. that said, many (as in hundreds of designs)can function with modest push/pull power and sound great as well. many designs which cater exclusively to the flea watt crowd are not good all-rounders, and in many cases, even the mega expensive horn designs come off sounding like a PA system....with no bass as well.

You jest sir?
'in many cases'......i;ve heard some great ones too....klipschorn, impulse, altec
