Which speakers are higher efficiency?

Hi, I am in the market to buy a high efficiency speakers to match my 300B with given 15W output. When I do some search online, I have 2 speakers in my mind:

Reference 3a Grand Veena Loudspeakers
Efficiency: 90 dB. 1Watt/meter.
Frequency response: 36Hz - 20 kHz (+/-) 3dB.
Up to 100 kHz high frequency extension.
Bass loading: F3@ 36Hz., tuned port,
quasi-second order, -15dB at 20Hz.
Impedance: 5 Ohm (+/-0.5 Ohm).
Power handling: 200 Watts RMS.
Phase: Almost constant at 10 degrees @94dB, wide band.

Focal 1037be
Type: 3-way bass-reflex floor standing speaker
Frequency response (+ or-3dB) 38hz-40hz
Sensitivity (2,83 V/1m) 91dB
Nominal impedance 8 Ohms
Minimum impedance 3,5Ohms
Crossover frequency 350Hz/2000Hz

Just look at the number, Focal 1037be is more efficiency, b/c it gives 91dB v.s. Reference 3a Grand Veena only give 90dB. Is that right? or am I missing something here?
Or can you guys suggest a 4~6k high efficiency speakers for me?
Thanks,

Agreed with JohnK, neither two speakers you are a good match for a SE tube amp. Sensitivity is only one factor you must look at; more importantly is a benign impedance curve.

You should consider one of Johns speakers (KCS), Cain and Cain or Carder sound (and many others)

Agree with the posters saying you need 98dB efficiency at a minimum for that type of amp, especially if it is single-ended, in which case you will want even more efficiency if you are in a large room. Horns match very well, as others have said. You certainly don't need to spend 4-6K, either, if you don't want to - I got a very nice pair of Klipsch Cornwalls on this site for only $600. You may need to spend a little more than that, but certainly not 4-6K. Anything in the Klipsch Heritage series would be good, or something similar.

I run a pair of 300b 8 watts SET with Coincident Triumphs Extremes and two passive subs with wonderful results filling a room 20x23x9
94db@1meter but most important a flat impedance curve of 8ohms

Actually, my power amp have two 300B tubes in each channel.

Rated Power Output: 24 Watts RMS
Input Sensitivity: 0.33 Volts for full output
Input Impedance: 100,000 Ohms

Since I don't listen music very loud, do you guys think 24W is good enough for Grand Veena? I love female vocal and Jazz music.
I was consider Avantgarde speaker, however, my place is little bit too small Avantgarde speaker even the smallest model.

Actually, no. About 100W is more like it. Regards
