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,

'Stability' is that which prevents the amp from oscillating. Just so you know. So in the phrase:
As I said above, so is an 80’s NAD3020, stability is needed,
- the term is being misused. In fact its unclear what is meant here. Are you saying that the NAD goes into oscillation when presented with a 1 or 2 ohm load??
You are applying criteria that could be used as a measure of a Linear amplifier to a Class-D amplifier which can current limit cycle by cycle, hence the current limit and power limit of a Class-D amplifier can be decoupled rendering your statement irrelevant depending on the Class-D implementation.


It needs to be able to almost double it’s "full" rms wattage for each halving of impedance, from 8 to 4 and from 4 to 2ohms, and I asked Merrill twice, to supply that, and twice the question wasn’t answered.

OK, so what is the definition of instability for these Class-D amplifiers? Since they have over current protection mode, and soft clipping capabilities the amp continues to operate, but not optimally. Without the use of an LED display to the circuit board (1200AS2 has this option), how would you even know it’s happening - is bad sound is the only way? Again, since the amp is running and making music, would this indicate it’s stable?
Many class-D amplifiers have feedback so could have similar instability as a typical linear amplifier.

Back to the OP’s question
What Class D amps will drive a 2 ohm load into his Thiel CS5’s

The proof is in the two posts done here, about Class-D and it’s ability to perform/drive "optimally" into hard loads full range, (not just to be stable!!) even with one of those speakers being very efficient at over 90db!!!

When are the Class-D spruikers going to stop trying to push them like they’re the total answer to amplification, and sell them for what they are, good for easy/medium loads and not hi-end "yet", like Agostino, Gryphon, Solution, Boulder ect ect for driving the types of speaker discussed here, and the topic of this thread!!!!!!!
