What Class D amps will drive a 2 ohm load


Just asking.

I see specs into 4 ohms but nothing into difficult speaker loads (like Thiel CS5's).

Thanks for listening,

Amazing for $599.00!!!
"says" again not by an independent tester.

  • 440 watts x 2 at 8 ohms
  • 775 watts x 2 at 4 ohms
  • 1200 watts x 2 at 2 ohms
Why get any of the others?? When you have this for $599

Cheers George
The impedance of the CS5 at 20Hz is 2 ohms and not .5 ohms as stated. At 10Hz it is approximately .6 ohms.
At 10Hz it is approximately .6 ohms.
That when the vinyl warp frequency will tax an amp, or even a bit of dc servo flutter when the mains chucks a slight wobbly.

It's been reported that Jim Thiel ended up using Krell 600 Watt'ers.
Correct type of amp, that will almost double down to 2ohms without breaking a sweat, though the 250 or even 150 watt'ers would do, they all can do the Krell doubling act.
There are many other brands that do the Krell doubling act also, all use Bi-Polar (bjt) output transistors, just like the Krells.

 And you maybe happy with that, because you don't know better.

   This is an unfortunate reality from those of us attempting to make a helpful suggestion with very little actual in home comparative experience. 

   After owning four makes and in home auditions of three other switching amplifiers I've been using a pair of Hypex nCore 400s to drive my studios monitors that dip down to 3.6 ohms, an Acoustic Image Focus 2R driving a menu of Bass cabinets, and various Velodyne subwoofers. My only suggestion is to listen for yourself.

   I'm a class D fan but I'm not fooling myself either. Their plate glass transparency along with switching amplifiers general lack of congestion make them a tool in my studio. In the living room they're simply no match for the relaxed musicality of my tube amps. All the best with that Ralph, you've got the ears for it.
