Why does my 15 inch v2 stops working it shows flashing red and green indicating light?
A shopper
on Mar 8, 2023
BEST ANSWER: I sent mine back and they replaced it. I think it has something to do with the amp. If you unplug it for about 30 seconds and let it turn completely off then plug it back in, it should start working again. Mine would work for about 5 min then start flashing again.

Try connecting to another bass outlet on your receiver or processor, that worked for me. I have a RMC-1L Processor (with L,C and R bass outs) and I changed it from the center bass channel to the right channel and that solved the same problem! So just simply try optional bass outlets (they all get the same bass signal)

I had a similar issue and still have it sometimes. It has to do with overloading the subs above 0db. I increased the levels on the subs to 6+db, then recalibrated so that the processor would not send more than 0db to the subs. Fundamentally the issue is that the subs are kicking into safety mode.

Is Fedex Freight usually good with these large Monoprice Monolith Boxes? My subwoofers delivery date has been postponed 2 times and its now about a week late so I am very concerned. Secondly if the box is damaged enough to cause concern should I then refuse the package? Thanks

BEST ANSWER: They were fine with my delivery, the sub came on a pallet and was well packed in the box. The sub itself was covered in a fabric wrap and styrofoam all around. Make sure you have a friend and a hand truck to get it inside, it weighs just shy of 150lbs out of the box.

Although the specs say speaker weighs 133lbs, the shipping weight is 220lbs. Mine was delayed a few days also, but it finally got here. It requires a special truck for delivering boxes that are that big (over a yard high and wide and tall) and weigh that much, so scheduling is a challenge. They did keep me informed though. I needed mine in the basement where I had built a theater, but to get there they would need to cross the lawn. He said that the dolly they use would never make it. Their dolly moves on pavement only. So it went intop the garage and I had to figure out how to get it to the basement.
The box would need a very large dent in it to reach the speaker. They really protected it in there.

Other than some cosmetic differences, recessed driver and such, what are the actual differences to product #24458, the other 15" sub?....specs seem exact?.... on that note, would it be better to get two of these and space them around the theatre, or 1 - M215? the logic being that the sum power of two single 15's is about the same as one M215.... does the splitting of location to two locations with single subs, out perform the dual driver in one location?

Splitting the subs to 2 locations doesn't normally mean more output but almost always leads to more even bass throughout the room if set up correctly with time alignment and proper placement expecially with more than one seating location. I can't speak for the m215s output though. Hope this helps

What are the power requirements for a 1000 Watt RMS amplifier? Does it need a dedicated circuit?
New User U
on Oct 26, 2021
BEST ANSWER: The power supply draws only what it needs. Based on actual amperage measurement, I have not seen this draw more than 5 amps by itself while watching movies and shows. If this is being used in a very large room, such that it's far enough away that your eardrums will not shatter, then it could draw enough for one 20A breaker. Realistically, this thumps and thunders *hard* at 5A, and I would not want to be near it if it's actually at its maximum volume.

It depends on what else you have on the circuit if anything. If it maxes around 2000w its a simple math problem you divide by the Voltage. In the US 120 meaning max it should use just shy of 17 amps. You should be fine it is the only thing on a 20 amp circuit. If you have other items it may/will not be enough.

I bought this for my son, so didn't hook it up myself. However, the manual says to use a mono cable to either the LFE or line-in inputs. Go from sub 1 on your receiver. The decision to use LFE or line-in into the sub might depend on how you have your receiver set up to cross over the bass. Hope this helps.

If your receiver has 2 subwoofer outputs, it is capable of driving 2 subwoofers. If you only have one subwoofer than just use one of the subwoofer outputs.
You can use a Y connector if your subwoofer has L and R input, or you can just use the L input since the subwoofer is not stereo.

BEST ANSWER: If you like low frequency and thunderous bass, I’d go with the monolith M15 V2’s. The room I have them in is 18X23 and two M15 V2’s fills that room with so much deep bass that it’s unreal. It almost give you that movie theater feel.
I use to have dual klipsch 12” subs and it’s nothing compared to what these 15’s can do.
I’ve never had any experiences with 10” subs but I’ve always heard and read that smaller subs are tighter and puncher but if you want deep bass, definitely go with the M15 V2’s. If you can afford it, get two. Plus a lot depends on the size of your room too. If you have a small room, one will be enough.

2. 15” will hit really low, more cone area. I wanted those ultra low frequencies that 10’s can hit.
3. Both will sound like monsters and you’ll be super happy.
I chose 15” and you can always plug ports for more punch and tune for better punchiness
Hope you enjoy. .

How does this stack up against the 13 in over all performance for music?
A shopper

BEST ANSWER: Both subwoofers have more than enough low distortion output for music so there is effectively really no difference unless you want to make yourself deaf. Look at CEA-2010 comparisons for max output. 13in has more output overall but for some reason the 15in does better at 12.5hz.

The specs for the v2 state that distortion is 3% vs 1% for the v1, however the measurements are listed as identical between the v1 and v2. Additionally, frequency response is slightly different between v1 and v2 yet measurements are identical. Does the v2 actually perform worse? Also, the amp renderings look different, has the amp module reliability or performance been changed in v2?
nik g
on Jul 26, 2022
BEST ANSWER: The v2 performs slightly better than v1. The amp is exactly the same in both, albeit with the v2 having different internal DSP settings since the driver was improved for v2. The render differences are mainly from having a different graphic designer do the renders.

Thank you. Can you please speak to the published spec differences where the v2 shows distortion of <3% 20~100 Hz (90dB @ 1m) while the v1 shows distortion measurements at < 1% 20-100 Hz (90db @ 1m). Has the DSP been tweak to favor some additional output at the cost of great distortion?
Great Distortion? Either 1% or 3% would be 100% inaudible, and any measurement differences like that could be attributed to different measuring days, weather conditions, wind, etc. You will find subwoofers from other companies that have distortion into the high 20s or even low 30s.

What is the preferred position in a home theater application?

It depends on the room. The best place to put a subwoofer really depends on the size of the room, room modes, and other aesthetic factors.

Are the spec on the 15in v2 correct. the old 15in model showed 19hz-200hz 2-ports thx eq and 20hz-200hz 3-ports thx eq. The new 15in v2 shows 22hz-200hz 2-ports thx eq and 20hz-200hz 3-ports thx eq. Yet their extended eq are both 14~200Hz 2 -ports and 16~200Hz 3-ports. why the loss of low hz capability on the 2-port mode on the 15 v2 in thx mode only?

I have a M-15 V2 Powered subwoofer. So far I am really enjoying it. I am not an audiophile and have a question on wiring. I wired a subwoofer rca cable from the audio cabinet through the wall to a wall plate about 15 feet away where the sub sits and plugs in via RCA jacks to the wall plate. Is there a benefit to taking it from RCA to XLR inputs at this point or should I just let it use the RCA's normally? Thanks for any advice.

BEST ANSWER: Thank you for your question. The benefit is that the audio will sound cleaner without the possibility of distortion since the XLR is a balanced connection.

Superlative subwoofers in every respect!!
Fantastic subwoofers in every respect. LFE in action movies makes you feel like you're right there participating in each scene. Very clean and clear with sound you can feel, not just hear!!

no frills good price
Write your review here. It must be at least 10 characters long. Consider whether you would recommend this product and what you like or dislike abouI was able to get one of these as an open box item for quite a deal. I think they way under state the weight on these. The shipping weight was 230 lbs+. After the pallet is removed these still weigh a ton. Also these are probably the largest 15 inch subwoofer enclosure in the market. The amp is also a basic amp with no bluetooth or other connectivity. Either way these do one thing well, bass tons of bass at a relatively flat response. I have a theater room that's around 18 x 29 feet or so. Way smaller than the recommended space and exactly as I like it. Now that it's in the theater I hope to never have to move it again. Hopefully it will last a long time.t it.

BEST BANG FOR $$$$
Tried SVS PB 1000, 2000 PROs and SB 4000 PRO and M 15 V2 sounds cleaner for less money. Not for someone that has limited amount of space. I upgraded the tiny isolation feet with a bigger one from SVS and it is awesome. Solid Thump watching movies. Watched GOT dragon scenes and wife loved it!

Now That I'm Educated, A Beast!
First of all, let me state that I was in search of the wrong thing previously. I wanted to hear that chest thumping bass all the time. What I didn't know was that a good subwoofer only reproduces the bass that is actually there. So, after sending a sub back (SVS PB4000) because of looking for that 24/7 chest thumping bass, I figured out that I should have been looking for a sub that gets low and produces bass when its there accurately, but not the boominess that I had grown accustomed to. This sub ROCKS! It provides crazy deep bass when there, but is accurate enough not to produce boominess when there is no pronounced bass line. But, when the subsonic bass is there it shakes the room and you can feel it. It can be scary! Love the sub now that I understand what to look for. Hope this helps somebody like me who needed a little help on what to look for.

Incredible sub, so happy I purchased this one!
I have a large basement rec room and didn't do a separate movie theater, so I needed a strong sub. This beast is AMAZING! Legit, I couldn't imagine ever needing more power than this or a second sub, this thing hits so hard watching a movie. Excellent value. I had originally planned to buy an SVS PB-3000 and got this sub for $400 less and I have read that this Monoprice sub is more equivalent to the SVS PB-4000 which was $1,000 more. Tremendous sub at a great value! It is large and heavy to move but if you can fit it into your space, highly recommend!

Great as always
I already had 2 of the 12s both v1/v2 but still had an older sub behind the couch. I decided to upgrade the Polk after the 15 went on sale and instead of getting another 12 I went for the 15. If space is an issue the 12 is probably still good enough for most. I would say its slightly louder than the 12s as the charts show, but since it was replacing another 12 that while not as strong it isnt super noticeable until you get to frequencies that the additional Polk could not hit and in those cases the other 2 12s where making up for it. Still a worthy upgrade since I have a large weirdly shaped room with 9 ft ceilings. Great job.

House shaking bass
Excellent sub, great for movies. I did a lot of research as I'm using this in the living room with open plan and 18ft ceiling and I wasn't sure if one will be sufficient. This size and power was exactly what I needed and this beast was able to rock the entire house single handedly. I haven't tried various placements, but seems like my first choice worked out well. It is very difficult to move it anyway, even with two people as there is nothing to hold onto. So, I had to use furniture moving straps to lug it around. I could feel the vibrations when I sit on any furniture (you don't even need bass shakers). Give it a week or so to break in and tune it. If the movie supports good audio I used THX mode, it's very clean, otherwise you can your use custom level ( I usually use this for music). I love 'clean' bass, so I'm very happy with this sub. This changed my home theater experience and made it possible to make it work in a big room! Great immersive experience and worth the price.
