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 ?

If you have a multi meter, you can use the test tone & technique provided here to calculate how many watts your speakers actually use: https://www.diyaudio.com/forums/multi-way/204857-test-voltage-power-speakers.html It’s super informative & useful: all you do is set your volume at the max listening level you use, then play the -12db 120hz test tone while measuring voltage at the speaker terminals. Square that value and you’ve got the maximum watts needed. Plenty to read at the link... |
And if you don't have a DMM, they're worth having around... I bought this one for $25 and it does just fine. https://www.amazon.com/Alloet-True-RMS-Digital-Multimeter-Voltage/dp/B072JMBLJS/ref=asc_df_B072JMBLJ... |
