Soundbar Subwoofer

[CFrame]

I have a Toshiba Soundbar with powered wireless Subwoofer. I recently upgraded to add an AV Receiver. My question is if I can utilize the Wireless Subwoofer with the new Receiver. I will be taking the Soundbar out of the equation. I've located the receiving component and found L and R signal contacts along with an AGND and DGND.

Failing the above, I wonder if I could wire straight to the speaker contacts inside the Sub. Understanding that I would be bypassing the amplified section. My thinking is that the Receiver is providing an amplified signal?

No you need the amplifier from the soundbar/ sub. Chances are the amp is in the sub cabinet anyway. Does your amp have a stereo line out you can use? Just don't hook up the soundbar to the sub unit.

I have an AV Denon receiver (I'm fairly certain it has a line out). I'm just trying to set up as balanced as possible without having to purchase another of what I have already. I'm hopeful that there is some way to connect on the boards with the signal line from the sub out on the Receiver.

Just use the monitor out from your receiver and connect to input of sub. The sub has internal crossover.

This is a wireless sub, so there is no input. I'm thinking there is a way to wire to the board directly at the wireless connection.

So the input was on the soundbar?

You may get lucky and find that the input gets changed to line level from the wireless board, but chances are it's integrated.

It looks like all the connections go to the soundbar and that sends a low level signal wirelessly to the sub. While there's a few different models of these, they all seem to have just a power switch and power cord on the back of the sub. I guess you can try opening the sub and see if there are any contact points on the board for inputs but very likely not. You can wire straight to the sub and bypass the internal amp but you now need an amp between the receiver and sub. You'll need to find out the resistance of the sub and it's rated power input. A lot of work for little gain.

If you're a little strap for cash but want a sub to get by until you save up for a nice one I would try looking for a used one.

bypassing the amp is pointless
your avr will output a low level lfe signal for a sup
sub neets wattage, usually over 200, or even over 500
your avr would never feed it enough

What are you talking about? His wireless sub is self amplofied.

yes it is, look at the post above mine where they said to bypass the amp, and the original post where the op thought about it

Bypassing the wireless module.
