Aloha to all!!

I was reading the guides here on Audioholics and I read this:

Connect the "Sub Out" of your Receiver / Preamp Processor using an RCA cable into a Y-cable into the "L" and "R" inputs of your subwoofer. Note: Unless otherwise stated by the manufacturer, be sure to utilize both inputs of the sub as many subs sum the "L" + "R" inputs to yield a 6 dB gain from the input voltage of the processor.


Well I have a YAMAHA RX-V 550 with a set of Wharfedale Diamond 8 speakers. I have a Wharfedale Powercube 10A sub.

I n the VERY SHORT manual that came with the sub it says to connect the "sub out" of the reciever to the LEFT input ONLY of the subwoofer??!!!

Can this be right...and if so...what is the use of the OTHER right input on the sub???

If you were using a receiver without a "sub out", you could connect the 2 stereo front outputs to the sub and then the left and right speakers to the sub.

Since you have a dedicated "sub out", I would be inclined to follow the instructions in the manual, and connect to just the left input on the sub.

simply put, this is not good advice.

a Y-cable can sometimes, but not always, be useful if a subwoofer's auto-on function is not reacting to input properly.

otherwise, that purported 3-6dB gain can be gotten elsewhere; like at the sub's volume knob or in the receiver's settings.
