Will 2 watts monoblock 45 tube amp work for 90db speakers ?


Hi my fellow audio friends ! I got a question about low power tube amp , I recently interested in a pairs of 45 tubes low power amp , they are around 2 watts and I know they work best on higher efficiency speakers like horn , I currently have a primaluna preamp feed s ss amp to my Nola boxer s2 90 dB at 8 ohm and a pairs of sub , I wonder at normal listening level will a pairs of 45 tube amp will have enough juices to drives them ? My listening room is around 15 x 17 , any input ?

It won’t satisfy you for long.  Not only will a 2w amp not have enough power for loud levels with a 90db speaker, it also won’t have enough control at low volumes.
Will 93 dB satisfy you? Because that is what you will get at 2 watts.
Not enough power amps will clip and give you NO bass or dynamics.If you want to use amps of this wattage you need 98db efficient speakers or you will be in clip city.Enjoy!!
Thank guys ! I may have to go for another pairs with higher watts than 2watts , maybe 10 watts class a will enough for my listening level , normal I don’t listen more than 9 o’clock on my 100 watts ss power amp.
