2. speakers
  3. 1300455217

Are these speakers fully compatible?

I have a 10 watt 300B tube SET amp with these specs:

Power output: <= 10W x 2, THD <= 3%, 1Khz
Frequency response: 16—38 Khz, -2dB
Output impedance: 8 ohms
Signal/Noise: >= 90 dB

I was thinking about getting a pair of John Blue bookshelf speakers for my small room and the speakers have these specs:
Efficiency : 87 dB / W / mImpedance : 6 OhmMax power : 30 W

Would I be better off getting a pair of speakers with a 90dB effiency or higher?

So, you have apprx. 3 wpc of clean power.Alas apprx. 4 db = 91db (87+4db's) of clean output from the driver/s. Can you get by on peaks of 92=92.5db of peak output.
Personally I can almost get by with that but, I have found
that most, NOT all, audiophiles ears are no longer sensitive enough for this to be adequate. As always YMMV.

Drew and anyone that wants to read. 18.4db of sound will take 85-95 watts of power,all things being equal.

One hundred watts equals a 20db gain.You can't rewrite the elect. laws at your leisure.
