Does subwoofer's plug have a ground prong (may prevent any hum sound coming from speaker)?

BEST ANSWER: To Inquiring shopper: the Monoprice 12" subwoofer does not use a 3 terminal 120 vac power-cord- -it has no
earth-ground prong. Its medium-size extruded-aluminum heat sink is used as an audio "ground-plain", with all
RCA audio sockets electrically connected to it. The heat-sink is mounted with wood-screws, which could
provide a convient way for you to connect an earth-ground. My speaker had no "hum" problems. Be advised
that this product is heavily built and a bit of an audio "brute".

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.

Can anyone compare this to the sub that comes with the Premium 5.1 system (10565)? I have the latter and looking to add some deeper extension and more bass coverage. I'm curious how this compares, and possibly if anyone has used both together. Thanks!

Monoprice 12in 150-Watt Powered Subwoofer, Black
Monoprice Premium 5.1-Channel Home Theater System with Subwoofer
BEST ANSWER: The included sub with the 5.1 system is 8" with 60W amp. the 150W 12" will give you much bigger and deeper sound. We created a new SKU that includes the 12" instead of the 8".

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.

The single sub itself sounds good. I have two subs on both side of tv with in ceiling speakers. 2 subs sound better than 1 if your receiver can handle 2.

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.
Abdul D

BEST ANSWER: You will only need to use one input, the red or white, no difference. Do not use the y-cable adapter because it will put your sub out of phase and not sound properly.

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."
You will need an RCA (subwoofer) cable and a "Y" splitter to connect it. Monoprice sells both.

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.

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.

Adds some low end, tends to be boomy
Larger and heavier than I expected, this sub adds punch to music, and especially movies. In sweeps, there appears to be nothing of substance below 40 Hz or so, certainly nothing below 35 Hz, and it gets muddy down that low. I got it for just over $100, so I have no room to complain, but I did expect further extension, at least down to 25 Hz. I've heard tight, deep bass from other subwoofers, but this ain't one of them. If your speakers are bookshelf speakers with, say, 6" or 8" woofers, this will add extension and punch. I have Klipsch Forte speakers, and at best, this adds some punch to bass drums in music, and explosions in movies. However, it doesn't add any frequencies below which my Fortes already reproduce. Don't expect $1000 performance from a $100 sub and you won't be disappointed. I'm not.

The 12in Sub ????
I am quite happy. It seems to be the perfect complement to my entry level Onkyo AV receiver. What audio Mfrs. do not state is that bass reproduction as well as mid n highs do not sound accurate at all UNTIL you add a Sub. Perhaps this is common knowledge among the Audio-Annointed, but I had to figure it out. With the crossovers at 125hz things sound really good. ~TEU

Bought for a gift
Bought to see the quality for a budget system (2-channel) Hoked it up to 2 sources to compare quality and sound/Feel. Seemed a little weak but I'm used to more powerful subs. Did a break in period of about 5-6 hours with Classic rock. Driver seemed to break-in in that short amount of time. re-boxed it and gave it to a person that was wanting to add a Subwoofer to their system. Was over the top on the performance of this Subwoofer. I added that I only did the initial break-in and using it more could increase the performance.
