I'm verifying. On a receiver with a separate subwoofer port, a single RCA cord or subwoofer cord runs from the receiver's separate subwoofer port to the subwoofer's white input port. Have I got it right?

On my receiver there is a single plug/port dedicated to the subwoofer and on the subwoofer there are two plugs/ports. Amazon sells cords that have the single connection on one end and the double connection on the other end.

Assuming your receiver has a dedicated "Sub Out", It uses a basic RCA cable. I use one that is made for a subwoofer and it is shielded against interference. You can use the left or right input on the subwoofer, it's a mono signal.

Unfortunately, I can't give you a "for sure" answer. If find an adapter that can allow you to use a standard subwoofer connection/RCA plug, you can make it work. The unit is self powered so all you have to do is get the signal to the sub. I use it with a sound bar which has a dedicated subwoofer plug. It is a great sub, a good as you can get without moving up to a real big time expense.

I do not have the Premium 5.1 channel sub but i do have the 150 watt Powered sub. I really like it. It has a crossover knob that lets you adjust which frequencies are coming out of it. (effectively a High pass filter). obviously at 150 watts Its not the loudest thing in the world, but for my home system its perfect.

My audio receiver only has a single monaural audio output. This subwoofer has separate line in L and R inputs. Will this work well with my receiver? Or is an adapter of some kind needed so both L and R inputs are filled in? From what I understand, and I may be mistaken, there's no L/R difference with the audio sent to a subwoofer.

Another respondent said not to use a "Y-Cable" as it will put the subwoofer out-of-phase. Having serviced both consumer and professional recording studio electronic equipment, that is not true! These circuits are generic in design and the first amplifier stage "sums" the Left and Right channels together into a mono signal so it doesn't matter if only the Left and/or the Right RCA inputs are fed from the single subwoofer output of your surround receiver. I would also recommend that if your surround receiver has DSP processing and filtering that delivers audio to its Subwoofer output then use that higher quality design and set the Crossover control of this subwoofer to the highest frequency. This will minimize phase shift in the subwoofer band.

Can this connect to YAS 107 Soundbar?
A shopper
on Sep 22, 2018
BEST ANSWER: Yes it can.
The YAS 107 has a subwoofer outlet for just that purpose. You just need an RCA "Y" connector 1 male to 2 males. The length of the "Y" connector depends how far your place your sub from the YAS 107.
(The Monoprice instruction manual shows a diagram connection of the Monoprice, both Left and Right "in" jacks.
However I have used only a single RCA jack ,left or right, and it still works.) I've read the only reason to use a "Y" is if the sub has an Auto-off and this sub does. The stronger signal using both sub "in" jacks keeps the sub form powering down if the signal is too weak, like when playing at low volume. I've been using subs for over 25 years and never had this problem, but just adding this for your info.
Monoprice has this sub's manual link on its site. Arrow down, almost to bottom on the page where this sub is advertised. Link is on the left.
The YAS 107 reviews also show pictures if you don't already own this. One is avforums, Dec 31, 2017.

Look up the specs on your ssoundbar at Yamaha. It states there is a "sub-out" so the answer to your question is "YES".
"While the YAS-107 comes with built-in subwoofers, it also has a output that allows for the connection of an optional powered subwoofer if desired. Adding another subwoofer provides even deeper, fuller and more impactful bass to enhance your movies, music and games. Yamaha offers a line of powered subwoofers or you use one that you already own."

Adding another subwoofer provides even deeper, fuller and more impactful bass to enhance your movies, music and games. Yamaha offers a line of powered subwoofers or you use one that you already own."

Everyone? I have (2) of these units - no hum, whatsoever. I use top-quality Monoprice single RCA cables for my subwoofers. Make sure they are tight to your sub(s) and receiver/pre-amp and that the receiver has proper settings. If the hum persists, consider that 30-cycle hums are usually the fault of a defective amplifier.

Hello Monoprice Team and Customers, is it possible to use the Monoprice #9723 with 220/240V ?
A shopper
on Apr 19, 2019
This is a 120v power block and it is not wired to function at 220 or 240 v. If that is all you have for power you will need a transformer to step down the power.

It depends on the kid of output you can deliver to the input on the subs amplifier. This unit is a bit harder to connect the input signal to it. It is easy if you have a preamp with an extra output on it. Look at the owners manual that shows you how you can connect into it. Hope this helps.p

I have mine connected to an amp/receiver which has an unpowered jack, since the sub has it's own power. I think the same would be true for a sound bar, if it has an unpowered jack for a sub. Somehow, this sub seems way bigger than most soundbars--I would look for something smaller.

BEST ANSWER: Yes it has a passthrough for stereo signal using rca left and right channel. If the sub output is mono you can get a y rca splitter. You can easily daizychain them together if the second sub has an rca in, also if you are using a stereo system it has passthrough for the left and right channels out your amplifier.

What gauge wiring should be used for the Hi Level inputs?
New User U
on Sep 1, 2020
BEST ANSWER: Without sounding flippant, whatever gauge supports the speakers attached to it. Were it on its own, the impedance is so high that it draws next to no current so you could get away with something tiny but whatever gauge you planned to run your speakers should go through the subwoofer. I like 14-10 gauges depending on the amplifier used to drive them. If it’s connected to some bookshelves, 14 is plenty and probably overkill.

The thicker the cable is the better, but I would not go below 12. Actually 14 is enough in my view. 12 is an overkill.
I am using RCA connection and might not be the best judge though. But subwoofer is pretty powerful and I believe can handle quite some power.

BEST ANSWER: I would think you can if you have the space. This sub is powered by a 150 watt power amp that run on AC (110 volts) not DC power (12v power). So you have to have a power invertor that can handle this amount of current, in order to work

Hi, I just received this subwoofer. Unpacked and installed with my pioneer 5.2 receiver. However, I am noticing 2 very strange things - the moment I switch it on (switch at the back) there is a very loud pop. Second, there is considerable humming without even being connected to a receiver. After connecting and playing some music, the humming is getting louder. Even at low levels I can hear the humming. Has some else also faced this problem? And what is the solution to this?

I had the same issue as you with this Monoprice 12" sub: it would hum loudly even with no inputs connected. However, I found a fix. This reply might be a bit late for you, but in case anyone else has this issue, here's what I did. Note: this fix involves opening the subwoofer amplifier, which could void the warranty, and exposes the user to live 120V electrical circuits. Only do this if you know what you're doing in a safe way. What I did was open the amplifier and re-position some of the cables. There are 3 small cables that run between the two circuits boards in this amplifier, and their physical placement affects how much RF interference they pick up, and thus how much hum/noise can be heard from the sub when it's turned on. In particular, the cable labeled "BASS" is very susceptible to picking up noise (it is the audio signal cable). I found that if it was close to the large transformer for the amplifier's power supply, and if it were at a particular angle, it picked up a lot of noise. So, I moved it around until I found a spot with minimal noise (I had to do this with the sub powered, so I could hear the hum change), then I hot-glued the cable to keep it there. Note: the 3 cables in my sub were tied together with a ty-rap, so I had to cut this so I could move each cable independently. One of the other cables, labeled "V+ V- GND" (which supplies power to one of the circuit boards), also required re-positioning to minimize noise. Note that when I moved/re-positioned the cables, I didn't unplug them: I only had to push them around a little bit to change the level of noise/hum significantly. There is a third cable connected between the two circuit boards in this amp, but I found that its physical position did not affect noise at all. My sub used to have a hum so loud it could be clearly heard from 20'+ away. Now, it's barely audible 3' away directly in front of it. As I said before though, opening this amplifier to do the fix I did can be dangerous, so be careful!
