Good morning friends.
I've got this wonderful amp recently and I really love it.
It is capable of delivering 500 watts into 4 ohmns, and 350 watts into 8 .......
Here the question (have read a lot about this) my cabins have the following impedance:

4 × 10: [/ U] [/ CENTER]
● SPEAKER: EMINENCE 4 x 10 "MADE IN USA (BP102 legend)..
● POWER: 800 WATT / 1600 WATT PROGRAM
● IMPEDANCE: 8 OHM
● HORN DRIVER WITH EMINENCE 1 "

2 x 10: [/ U] [/ CENTER]
● SPEAKERS: EMINENCE 2 x 10 "MADE IN USA (BP102 legend)..
● POWER: 400 WATT / 800 WATT PROGRAM
● IMPEDANCE: 8 OHM
● HORN DRIVER WITH EMINENCE 1 "

Given this information, and knowing that the car 2 x 10 will get twice the power 4 x 10, my question goes out how "hard" and as I get to push hard, without breaking the speakers 2 x 10.
Generally give concerts in bars for about 100/150 people​

+1 it makes little sense to combine these 2, as the limits will be the capabilities of the smaller cab. That leaves the larger cab under utilized. Better to use 2 of the 210's in this case. But, if you do this, pay close attention to the 210, as it can get pushed too hard, and not be noticed, with the 410 blasting away unharmed.

Thanks for your answers, I need to take my doubt ......
As to the division of power that would take each case (50% / 50%), knowing that the smallest 2 x 10 can receive a total of 400 watts, for playing with a good high volume, would be getting 250 watts by the head? If this is correct, would not have to break into problems with the speakers?
Apologize, I've never had any problem with this configuration, but to get a new head, it seems that what I had believed to be clear or is no longer so.
Again thanks for the info.

Each cab is 8 ohms giving a 4 ohm load with both. Your cabs together will easily handle the head's output. Your biggest electro/mechanical problem will be driving the amp into distortion which can cause heat buildup in the drivers. You just need to listen-most drivers begin to tell you when they've had enough.

As long as the distortion is at a level that won't blow the speakers, they will be fine.

Thank you all for your opinions and advice I was playing a lot with this configuration at high volume, and has responded very well, lots of definition and clarity; do not feel I have danger of rupture, as Jimmy said, it is best to hear what happens with speakers.
It may not be the best idea this combination of boxes, but for now, a fairly high volume and has given me good results.
I still feel like there's a bit more space to increase the volume, but I've come this far, no need to force anything to regret later.
That said, I must confess that I've fallen in love PF 500!

Just remember that if it sounds like it might explode, it will.[Invalid or Expired Link Removed][Invalid or Expired Link Removed][Invalid or Expired Link Removed]

I have a pf500 and use an Ampeg 410HEN. I was able to try an SVT 210AV with the 410 at a jam once. It did not help at all, I lost all the tone I was pushing and it really did feel completely restricted by the 210 rather than being louder or having more. I kept pushing my amp for more but it just couldn't get anything close to what I normally get from the 410. Could be just my experience, I enjoy a punch to my sound/tone and usually keep the bass backed off to 3 or 4 on most amps, adjusting mid and treble to taste, for reference on differing eq expectations if relevant.

Merry Christmas Friends.
December 30, the day in the evening I'll be playing in a concert with the band at a place for 200 people, there will be the litmus test of PF 500 / 4X10 +2 X10, considering all their advice and opinions, coupled with tests I've done during these days, I decided to go to the show with all the potential.
Surely I will be informing you of the outcome soon.
Thanks again, I'm still always learning a little bit of everything and everyone.
