brutal sounds bs2.1 dyno WTF over 90% efficient???????????????

Recommended Posts

91% at 1 ohm 2300rms wtf? i never seen anything like that.. also it almost does twice rated power at 4 ohm and 50% more at 2 ohm.. these things will sell like hotdogs at a ballgame..

Brutal doesnt care much about profit margin.

 

When their 5k came out, they were selling it so cheap that Zenon emailed them that other customers of that board were complaining about Brutal undercutting their prices. (B2 and AL both have a 5k with that board)

but how they make it so efficient? every company should charge $50 more and use whatever part does that lol.. if u could run a 1500rms amp on stock electrical with no problems it'd be worth the $50.. i also don't think i've seen a amp do double rated before and diff not at 4ohm

Ratings don't mean anything. The manufacturer knows what it puts out and underrates it for a wow factor.

That's what I thought.... I retested a ton and changed the batteries, was working fine.... I may try a couple more amps and see what happens... It was accurate on the Orion test.

The buildhouse rated the amp... Joey at Brutal Sounds had no idea the amp would outperform the ratings by that much...

Send it to us, we'll test it here and get you true efficiency readings along with graphing, etc..

 

IVe never seen nor would accept an amp would increase efficiency with lower resistance.

I'd be interested in debunking the results.

Doing this test made me wish I still had my old clamp... I got the same results time after timeàm

I'd be willing to bet it has to do with the power supply caps. They should be drained by the end of one of the certified/uncertified tests but it's hard to say.

 

A real answer would be taking total power used (as in area under the curve) of the input and output and calculating based on that

 

Something was wrong with the clamp.

Clamps just fine, it's really a matter of resolution in time and the tool not being "right" for the job, although it is a great ballpark. If you had hundredth of a second resolution and data logs it would give you a much better idea of actual efficiency

This video clearly explains how you can set an amp to get those HUGE power results.

It really doesn't...... All it explains is that you want the certified number and not the uncertified number or dynamic. Adjusting the gain upwards could only change the certified number if you end with a higher voltage (quicker build is easier on the power supply / batteries), but it won't change the end result if the ending voltage is the same... Same with the uncertified number.... sometimes the uncertified test can end before the clip point... you can adjust upwards to reach the clip point faster... but when you clip.. you clip and the test stops.

I should say I think the Uncertified 1 ohm test seemed pretty right on... I see 74.57% efficiency at clipping

Any chance it has a second or third set of rails that switch on when needed, resulting in the somewhat better efficiency? I like the cap idea, too. Any of these monster amps using ultracaps inside yet? Just throwing out ideas.

Edited by ciaonzo

Saying "clipping doesn't kill speakers" is a half-truth at best. Technically no, clipping itself does not hurt the speaker. But in clipping your amp, you can easily create a situation that WILL kill the speaker. Was the squared waveform the DIRECT cause of the failure? No. In the end, the answer is, always has been, and can only be... heat kills speakers. BUT, clipping increases heat generation, sometimes by a drastic amount. So to start a thread simply to state that clipping does not hurt speakers is, again, a half-truth at best.

Brutal Sounds posted Dyno pics on their Facebook page. Their 5.1 clamped in at 4890 @ 1 ohm @ 13.89 volts. 240 amps drawn.

Doesn't seem possible but maybe these are just stupid efficient.

Thats like 150% efficiency, kinda violates the laws of physics

I am willing to be the clamp was only on one input..... real number would be double that
