I don't know if the specs are correct on the Monolith 12", but it shows the weight being 98.5 lbs. That's well over 30lbs. more than the 65.6 lbs. the PB-2000 weighs. Csbinet is also a bit larger for the Monolith over the PB-2000. It certaibly is a monster for a 12" ported sub.
I stand corrected. Dimension 22.8" x 16.7" x 23.6" , weight 98.5 lbs. That is a monster 12" sub for sure!

Wait...You have one? Care to post some impressions? Thanks in advance!

I do have one. It's my first real sub. I can only compare it to an Onkyo HTIB "sub" and the Monoprice 12 inch 250 watt 9723 sub.

Overall I think the Monolith 12 is fantastic. It plays very loud and very low. The sound at first seemed less full than the 9723 sub. I think that comes down to the very clean output of the Monolith. The 9723 seems to have much of it's output as harmonics, whereas the Monolith is just the clean fundamental. I don't have any measuring equipment to verify the specs that Monoprice lists for the Monolith subs, but to my admittedly untrained ears this sub is fantastic.

I watched Hot Fuzz with the Monolith sub recently. I was shocked by the crazy amounts of deep bass it had. I'd watched it once before with the Onkyo HTIB sub and I honestly had no idea about the crazy bass in that movie. I haven't heard the Monolith make any unhappy sounds. No chuffing. I'm running it with both ports open, sub eq set to THX, crossover bypassed and using my AVR's crossover. I've got the Monolith Air Motion Cinema bookshelf and center for the front with Dayton B652 airs for surrounds.

The build quality seems fantastic. I could find nothing at all to nitpick on. It seems to weigh what Monoprice says it does (judging by feel, I haven't tried to put it on a scale).

The only downside I can think of is the size. It's big. It matches the description on the website however, so I knew that going in. Considering how good it looks the size doesn't bother me. My wife hasn't complained yet. That may change when the second one is delivered this Wednesday.

Hello all. I was hoping to see some reviews/feedback regarding the new 10" model by this time of the year. I see Monoprice added some nice new graphics regarding the insides of the subwoofer and the components of the driver. I'm shopping for a $500-ish dollar subwoofer this weekend. How do you imagine this 10" 500w subwoofer might compare to the 12" 350w Outlaw model on sale this for $549? Thanks.

At $500 delivered the SVS PB12NSD is probably the best or safest bet. Great warranty and customer service, 45 day trial period, proven to be a good performer.

On sale this weekend or until supply runs out.

Per the data-sets available on both the outlaw has 2-3dB more headroom >50hz, the mono-10 has 2-3dB more <35hz...40hz is about equal. Remember, that is max output capabilities. Up until you approach those respective limits the two products will likely sound more similar than not.

At $575 the hsu vtf-2 rocks both of them. Equaling the mono-10 down low and exceeding the outlaw in the mid and upper bass. From 50hz and up you'd need dual mono-10 subs to have similar headroom to one vtf-2 as an example.

What is your take on the Mono 12" sub? How does it compare to similar offering from other ID, SVS, HSU, Rythmik, etc... per data available and/or experience ?

BTW Tom, while I have you here, would you recommend one 15" ported sub or dual VTF-2 or similar sub for 25 x 21 x 8 room? 80% HT, 20% music. Never listen more than average volume. -15 on the receiver (speaker level calibrated to 0, running the sub hot maybe 2 or 3 db over that). My room has one null spot regardless where I COULD put the sub, in front or back of the room.

Check with hsu on the one vtf-3 versus two vtf-2 question they'll be more able to offer product specific feedback. In general, one larger will tend to offer a better "output/dollar" ratio. Also, going with one large sub now may be more "future proof" in that you can always add a second one down the road if you feel the need. If you go with two smaller subs you might be in "start all over mode" later if you decide to upgrade as most don't want more than two subs in their rooms.

The Hsu vtf-3 is $850 versus $800(for the mono12). The Hsu has a *huge* advantage with approximately double the output capabilities from 25-100hz. 15-20hz the advantage for the Hsu is much smaller. Svs should never be in a best performance/dollar discussion against true ID companies like Hsu or rythmik unless you're getting half off the svs or something(like the pb12nsd). Pick a hsu---vtf-3, uls15 for example...and you're spending double at svs for similar performance. Hsu just needs to call the uls15 the new history making uls16(!) and then everyone will get on board

Tom - Thank for taking the time to give your honest opinion. It is rare indeed to see someone spelling out the truth without bashing another other brands and pushing their own product.

I have been going back and forth with dual vs single, sealed vs ported for a while. I used to own a JL F112 and wanted similar performance on a beer budget, LOL. No luck so far.

I am not a fan of SVS either. I too think their products are Big Box retail like with big markup. That is why I passed on the PS12 NSD that they have on sale for $499.00 this Black Friday. If I get a ported 15" now, there will no second one down the road due to size and cost, WAF! I like the ULS15's size but not sure if it enough for my big room. I don't push any sub hard though but I do want to hear the bass even in low volume listening, maybe sealed is good enough for my listening habits? Looks like I need to choose my 15" very carefully. I will most definitely read up on PSA subs as well. I am not in a rush.

I would get dual Rythmik FVX15's for $1858 and save $340 compared to dual Ultra-X13's for $2198. Perfomance wise they will be very similar.

I'll probably hold off. I'd like to see more hands on reviews of both the Ultra-X13 and the new Monoprice 15. I am considering duals of those in the mix as well. I listen to a lot of music, so I am interested in seeing some feedback. I may miss out on the special pricing, but I want to see some reviews. I am leaning Monoprice vs some of the favorites here. Just need some feedback from someone that's put it through some paces.

Why? Just want to be different? Not there's anything wrong with them per se, but the Monoprice models don't seem to offer anything above and beyond what the established ID brands already offer (other than THX certification, if that's important to you). They seem to be poor values compared with HSU, PSA, Rythmik, JTR, or Seaton.

My humble main system:
Vizio M75-E1; Oppo 203 universal UHD player; Denon 4300H AVR, Dual PSA S1801's; Monitor Audio Silver RX-6 mains, RX center, and RX surrounds; one pair NHT mini Atmos speakers; Home-built HTPC (Xeon E1230, 16gb RAM, Crucial M500 480gb SSD, GeForce 980Ti, Corsair CX600, CoolerMaster mini-ITX case); Roku Premiere+; Amazon 4K Fire TV

Well, I don't have a brand loyalty. Not that I want to be different... but they are two new options I would like to consider. I don't disagree with you on your recommendation as all of the vendors you listed have great, proven products. THX certification sounds flashy, but not a deciding factor for me in the least.

When I say Monoprice vs the favorites, I don't mean to say that I already prefer them... just that I'd like to see some real comparisons with the big dogs to see how they stack up in value, use, performance, etc.

But I am kind of hung up on the possibility that the new players COULD bring something to the table. Maybe not, but I would like to see some real world testing. They have been shipping, so we should see some feedback on them I hope. I just want to make a good assessment for a purchase that will be serving me for a very long time.

Thanks so much for the input. I greatly appreciate it.

Jx

All the more reason to go Rythmik. Good thing is the dual discount on the FVX15 isn't just for the holiday.

I wouldn't rush to that conclusion. Let's see some pro and consumer reviews first. I for one is very curious to learn if all that beefy enclosure/weight translate to excellent performance.

The 15" looks very interesting. Passing CEA-2010 at 12.5Hz is impressive as are the distortion measurements.

I'm not a fan of using HDF as it just adds weight, not performance. But, maybe it helps prevent shipping damage?

I'm going to grab a hold of one. Stay tuned….

The 15" needs to defeat a Rythmik FV15HP at this price point. That's a tall order. I'd love to hear what you think. The 15" looks great on paper, for sure.

The Monoprice 15" in house CEA 2010 numbers are crazy... They are better than any 18" 1000W ID subs... OMG...

Not only does the 15" defeat a Rythmik FV15HP, it also beats a FV18 by 2dB across. The Monolith 15 is only $1299 shipped!!!

Not only does the 15" defeat a Rythmik FV15HP, it also beats a FV18 by 2dB across.
Now use the proper values for the mono15(2m RMS not 2m peak) and use the proper values for the FV15hp(two port mode as that gives you the most similar FR for both products). Let's crunch those numbers one more time..

Would that be long term averages on Databass? I don't see an apples to apples set of data to compare the MP Monolith subs with the Rythmik. I see CEA-2010 max burst, CEA-210 Short-term averages and Max Long-term averages.

Apples to apples is easy in this case. He made a mistake and used 2m peak for the mono15 and 2m RMS for everything else in the chart I'd guess(all I checked was the fv15hp). So he just needs to subtract 3dB across the board for the mono15 to properly scale it.

http://data-bass.com/systems click on CEA MAX BURST. Everything in that chart is 2m/rms


https://www.monoprice.com/product?p_id=24458 Scroll down til you get to the "2 ports, RMS" chart then compare it to the above.


He also should use the fv15hp data-set for both ports open as that *very* closely mimics the FR of the mono15 with two ports open. Same with the fv18 you have to use the data-set for both ports open(he used one port open). If you don't make these two adjustments the rythmik subs are shown at a disadvantage in terms of the output numbers because they would both extend much deeper in the FR graph. When comparing output you should always try to find the extension "modes" that are most similar.

Once you those three corrections the chart will look significantly different

Good catch!!! Thank you for pointing that out!

Duh... Focus, chucky7. Focus!!!



Now it's just slightly more than Hsu VTF-15H MK2. So no, Rythmik FV15HP is still the leader in output.

You still need to go back and use the two port mode for the fv15hp and the three port mode for the fv18. The way you have it now isn't fair to the rythmiks.

Are these the appropriate data sets to compare?

I know what you are saying.

However, I have always used the product's max extension numbers on my chart... Fair or not...

All that matters is that the Monoprice Monolith 15 boasts respectable output for the price.

The first and the second images are, yes. The third image is the mono15 with all three ports open. There's not really a similar "mode" on the rythmik subs(fv15hp or fv18) in the chart referenced so I would leave that one out. Well, thinking about it...you COULD use 3 port mode on the mono15 for comparison to the Hsu two port open mode. That would have them with very similar FR IIRC.

http://www.hsuresearch.com/products/vtf-15hmk2.html

Scroll down and find the TWO PORT mode. Now, don't forgot to subtract 9dB from the hsu numbers because they are 1 meter PEAK.

The third image in your post for the mono15 is 2 meter RMS(three ports open). We need to subtract 6dB from the hsu data for the difference in distance. And then subtract another 3dB to properly convert PEAK to RMS in this context.
