Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

In the application notes on calculating the performance of an amplifer/speaker combination under,  ' AHB2 THD+N and Power into 4 OHM BRIDGED MONO' it shows THD+N is .00083% at 518 W. It reaches 1% at about 590 W. 

@georgehifi This article https://benchmarkmedia.com/blogs/application_notes/ahb2-driving-pmc-mb2s-studio-monitors also talks about second iteration of using ABH2 as mono blocks. 

Seems like outstanding question is just the damping factor everything else looks excellent to me. I will ask this question to Benchmark and see what they say.

Benchmark does seem to perform quite well in bridged mode, in-fact lot of thought went into making it work in that mode. That is why they never made it put out a lot of watts in stereo mode. Even at $6k and putting out 500w per channel at non existent distortion and quite good voltage peak 64.4(beats the requirement I have which is 54) is a deal compared to what is in the market today. Please feel to correct me if I am wrong.

Only Bryston 4B3 comes close at this price range and it suffers from cross over distortion that benchmark does not, if I understand it right.

I’ve tried geek101 with links to pro and cons and every which way, the site and manual, and post you’ve presented are just too ambiguous.

Purchase another one I hope for your sake two bridged amps can do it as good as just one  bigger non bridged amp can, I seriously doubt it.

Cheers George

Are you speculating, or do you have actual experience with the amp in different configurations?

didnt thx design the amplification and power stage of this amp
