SPL with pf50 + Barefaced 410 -> 118 dB
SPL with V4B + Barefaced 410 -> 121 dB
For comparison, you would get 119 dB with a pf-350 head and a Ampeg 1x12 cab (PF-112HLF)

The V4B would be twice as loud through that cabinet and the pf50 would be not quite as loud with that cabinet as a pf350 through a 1x12 (8 ohm, I guess?) for reference.
No, twice as loud would be + 10 db.
+ 3 db is only slightly louder
+ 1 db is a barely audible difference, so PF-50 + BF410 is pratically identically loud as a PF350 + PF-112HLF
It's hard to answer your question because we don't know what is a "medium loud rock band". It could work if you on the lower side of medium loud, and it would be slightly better with a VB4.
It also depend on your EQ, it could be OK if you play with a lot of mids, but you would struggle if you want a very bassy tone.
Ok, yes. Twice as powerful, a little less than 25% louder. Thanks for correcting me.
I would be more concerned about rehearsal than gigs, it should be fine with the help of a PA
50 watts is great in the studio but won't get you far on most stages no matter what cab you put them on. It is possible to get enough stage volume but not likely.
It's a tight fit. Could be just enough or it could fall just short of the line.
Depending on your tonal goals. If you want deep lows and a clean sound, forget it.
When you go for more of a mid heavy sound, have no low B string to cater for, and don't mind a little distortion from an amp that's pushed hard, you could be golden.

in theory yes
if the modest speaker (200W RMS thermal) in the good sounding PF-112HLF would survive the PF350's 250W @ 8Ohms (also not accounting for power compression)
Both PF-50 + BF410 and PF350 + PF-112HLF would require serious constraint from fellow band members
@Bertone - for a reasonable degree of comfort, no the PF-50 won't do it. Either V4B or PF350 (or bigger) plus a good 212 or 410....
Some 4x10 speakers are more efficient than others. Barefaced tend to be more efficient than most but I don't know if they're the most efficient. Using a high pass filter can help improve efficiency of the overall system by filtering out low frequencies that wouldn't reach the audience anyway.
The SPL (Sound Pressure Limit) is not measured, it is calculated from metrics provided by manufacturers.
SPL = (cab sensitivity) + ( LOG ( power ) X 10 )
With :
cab sensitivity = measured from the cab @ 1 W from 1 meter
power = minimum between amp power and cab power handling
amp power = for the cab's impedence, expressed in W RMS
cab power handling = in W RMS
I'm not sure about measurements at 1 KHz. I suppose you're speaking of the cab's sensitivity?
Ampeg just say for the 410 (no info about frequency range)
Sensitivity PF-410HLF: 101.0 dB SPL 1W/1m
Mesa is the only manufacturer who gives very detail specs: example for the Subway 4x10 :
Average Sensitivity (RMS) 50hz-1000hz
100.4dB/1W/1M
Barefaced says for their 4x10:
Broadband sensitivity 101dB
So maybe the word "Broadband" for Barefaced sensitivity refers to something like Mesa's 50hz-1000hz, but who knows?
Normally, a Barefaced 4x10 should be much louder than and Ampeg 4x10, so maybe BF's "Broadband sensitivity" is not equivalent and should not be compared with Ampeg's simple "Sensitivity"
If think all manufacturers should be obliged follow offical standard to publish the specs of their gear
@Wasnex can you help?
Maybe a dumb remark, but the frequency range is listed on the Barefaced website at 30 Hz - 6 kHz, so is that the numbers you were looking for?
See: Four 10 – Barefaced Audio
Maybe @alexclaber can help shed a light?
I use an Ampeg PF50T with an Ampeg PF115he as my main gigging amp. Have played some good sized bars with it. I put an Electro Voice RE20 mic on it so it only has to be loud enough for me and the band to hear. Also, I use it at rehearsal with a pretty loud 90's - current hard rock band. They are so loud that the drummer complains about it, if that tells you something. It keeps up just barely. So, with a 410 cab you could get by just fine as long as you let the PA do most of the hard work. That being said. There are a lot of light powerful solid state heads that, although they may sound different, sound just as good. I posted in another thread that gigging with a low powered tube amp is more of a lifestyle choice than an audio one. If you want to do it, you can make it work. After all, people play completely ampless and use only a modeler into the PA. That seems acceptable. A low powered tube amp isn't a lot different.
