Wadia Inuition (Class D amp) connect with subwoofer


Hello,

it is possible to connect subwoofer SVS SB-1000 with Wadia Inuition (Class D amp) via speaker connectors ?  Did anyone connect Wadia Inuition with subwoofer ?

Thank you!

Hello spacelab4,

     Yes, you can connect the SVS SB-1000 sub to your Wadia Intuition integrated amp via the high level speaker connectors.
      The only issue I noticed is that your Wadia uses banana plugs to connect to its speaker outputs. That is, a red pos. and black neg, banana plugs connect to the amp's speaker outputs and pos. and neg. bare wires, on the other end, connect to each of your left and right speaker inputs.
      I believe the simplest method, to hook up the SVS sub, is to use two 18 gauge or thicker speaker wires with bare + and - connections on each end. Connect one wire's + and - terminating wire to the left speaker's + and - terminal inputs and connect the opposite end of one wire's + and - terminating wires to the SVS sub's 'high level speaker input' left channel input. Connect the other wire's + and - terminating wire to the right speaker's + and - terminal inputs and connect the opposite end of other wire's + and - terminating wires to the SVS sub's 'high level speaker input' right channel input.  
      NOTE: This connection method will require you to double up the bare wire+ and - connections on the back of both your left and right speakers. Don't worry, the connections between each speaker and the SVS sub are only fractions of an ohm in impedance and will not negatively effect your speakers or Wadia integrated amp/power dac.

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,
