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 ?

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. 
@soix thank for your suggestions but I think I have a wonderful combo tube  preamp plus tube dac feed to my lovely Yamaha mx1 with dual transformer , the mx1 I purchased was 600 bucks compare to 2500 as new and I think I got a very nice combo already , for now I just want to try low power tube amp with high efficiency speaker for low volume listening
