Looking at a pair of these to use with 35 wpc Cambridge Audio amp-- Evidently sensitivity is 98 db. Anyone have experience with similar floor standers that will be happy with that low wattage? Any guidelines for what db level we should be looking for with yhat kind of powee? Yet another realm of mystery for those of us without EE education!

Klipsch uses 1/4th space sensitivity measurements, these will actually be around 92dB sensitive (still well above average).

Listening distance is a dominating factor. As an example:

Base sensitivity of RP-6000F: ~92dB
Room gain: ~+3dB
13ft listening distance: ~-8dB
20W (8ohm): +13dB
Result: 100dB

Thanks for the response! Does my original question even mean anything? Can you tell by looking at db ratings whether an amp can adequately drive a pair of speakers?

As I pointed out, how far away you will be sitting is a huge factor, a desk setup needs a hell of a lot less wattage than a 25ft long living room.

92+3=95-8=87+13=100db

Thanks-- I would be >6 ft away in a 10x12 room.

To a desired volume, yes, more or less, if you can believe manufacturer ratings.
3 db = power x2. Or 1 watt + 3db is 2 watts, 2 watts + 3 db is 4 watts. etc.
10 db = power x 10. Or 1 watt + 10db is 10 watts, 10 watts +10 db is 100 watts.

So if a speaker is rated at 92 db at 1 meter with 1 watt of power
A 100 watt amp will drive it to 112 db at 1 meter.
Follow the math?
