Wadia Inuition (Class D amp) connect with subwoofer

Hello Tim,

thanks for your answer, I understand the way it connects. It is not a problem in the load, the problem can arise if the minus of the speaker socket on the Wadija if is not a real minus but an active inverted output that D clas can have. Subs on loudspeaker level inputs generally have a minus of that input tied to ground. This can lead to malfunction. For that reason I am not sure.

Hello Spacelab,

     An active inverted output that class D can have? Where did you read, or who told you, about this complete falsehood and load of crap?  There's a lot of disinformation that's been spread on audio forums over the years about class D, but this one just may take the prize for one of the most illogical, unbelievable and completely false.  This is the 1st time I heard about this lie.
     Over the past 2 decades, I've used 1-2 self amplified subs in my various systems with class D amps with no issues at all.  Class D amps are just a different type of solid state amplifier and there is no such thing as an active inverted output, and it's safe to use 1-4 self amplified subs, with any ss amp whether it's class type A, AB, D or H. 
     In fact, class D is probably the safest type of ss amp to use subs with due to their self monitoring circuitry that quickly shuts itself down when any serious condition is detected.  I suggest you reread your Wadia amp's manual and learn more about them.

Best wishes,

Hello Tim,

thanks for your answer. I got that information from an electronics engineer, but I also see that it is written about on the Internet. The Wadia amp's manual do not say anything about that. I sent an inquiry in Wadia but did not receive a response. I sent an inquiry in SVS, they say there should be no problems. I hope you're right.

I am not an expert. I think the issue you are concerned about is if your have a true differential (complementary) circuit. If so the negative speaker levels are not a true ground and can short your amp if touched together. Many balanced circuits are not complementary so maybe you know that yours is? I believe this is the same as supporting the AES 48 standard but again I am no pro but know enough to be dangerous.  

Hello Spacelab,

     SVS is correct and I'm certain that I'm correct.  You won't have any issues.
     BTW, I like your Wadia integrated and read a few very good reviews on its performance.  Most of them mention that performance is improved significantly by using a good quality aftermarket power cord.  It doesn't have to be an expensive one, you may want to read a few reviews on the Intuition and aftermarket power cords in general.

  Best wishes,
