What Class D amps will drive a 2 ohm load

Holy moly, 3000w for $299?
That amp blows away the puny watts in my stable.
What was I thinking!

Wait a second.................

That’s right, it doesn’t matter how many watts you have, if you don’t have the current to back it up all the way down into 2ohms and less, with speakers like the OP has in the bass, you got s**t.
Like I said the "puny" 25w Mark Levinson ML2 monoblocks will slay them "to a given volume level"

Cheers George

According to George’s standards, the Behringer is a great amp:

440 w/ch into 8 ohms
900 w/ch into 4 ohms
1500 w/ch into 2 ohms.

That is 27 amps of current per channel at 2 ohms, far more than the 7 of the ML2.   

Are you serious! You buy it and drive the Op’s speakers then


You are really in a world of denial. if you think this Class-D can out drive the 25w ML2’s "to a given level into these OP’s speakers."
I’ll lay money on it also that those watts are not real or RMS, would be nice to see some independent test, at 8,4,and 2ohms

You buy it and live with it, because you obviously think 3000w can sound better than 25w into the OP’s extremely hard to drive speakers.

It’s like saying a 1/4mile dragster with 8000hp can get to the top of Pikes Peak hill climb faster than a 100hp rally car, delusional is the only word, even the most technically inept on these forums would think so.

This is so weird.  We have a guy here who thinks that one thing he makes up means something.  No one else would make up such a story.  You don't need double the wattage into 2 ohms to drive a 2 ohm load.  All you need is an amp that is stable into 2 ohms and has enough power to drive the speakers.  If your speakers are 87db at one meter....then lets say it is 83 db at your listening chair.  That means 93 db will be reached with 10 watts and 103db with 100 watts.  If that is as loud as you listen...I rarely listen this loud.... then a 1000 watt at 2 ohms amp will give you plenty of headroom.  This is simple science. 

If an amp can double its power from 4 to 2 ohms that means it has a very stiff power supply.  However, it does not insure that it sounds good with any load.  This is just a static test.  It means very, very little by itself. 

If you get 20 different amps that do 1000 watts into 2 ohms (with stability) then you will get 20 different sounds.  Some will sound bad, some good and some great.  The sound of an amp is dependent on hundreds of different things.  One factor (a made up factor) does not make a good sounding amp.  I made my amp sound way more dynamic and alive by doing various mods to it.  The power did not increase, the amps it can draw did not increase......but the powerfulness and transparency of the sound increased.  

Why oh why would anyone make a speaker with a 2 ohm load?  It makes no sense.  It is not more linear and/or lower distortion to have lower impedances.  If you have a speaker with a 2 ohm load that means you cannot use moderately powerful amps (that may sound better and be cheaper), you have lower damping factor and it is known by almost everyone that the lower impedance an amp has to drive the more distortion the amp produces.  Only those designers stuck in a paradigm from the past will make speakers that way today (Wilson, etc?.).  Even Magico has raised the impedance of their latest and best MKII speakers so they do not dip below 3 ohms.  These guys are smart.

The trend is for more sensitive speakers and/or powered woofers.  This is a good idea.  Look at the latest Spatial and GR Research open baffle speakers.  In some models you only drive the mids and highs (92-96 db sensitivity at 8 ohms) and you have either servo woofs or powered woofs on the bottom.
