Monolith 15 inch V2 THX Subwoofer Unboxing & First Look 

Exactly, not fully setup yet as no AVR but I’ve no doubt I’ll be impressed when it’s hooked up properly as others reviews have shown.

That thing is a BEAST! You should probably get two of them . Ha. no such thing as overkill.

That’s the plan, 7.2.4 with one of these in each corner.

@@MATechRU-vid right on, dude!! Go for it!! also, that comment was more aimed at RobZilla . I've heard his and it's a serious sub! Especially considering the size of the room. Everyone should have two of these subs lol. One day when I grow up I want a couple of them ha. So badass

👍🏽

I always preferred the way 15” subs sounded even when I was into ICE. Despite running 4 x 15” subs in my audio setups incar the sub sonic frequencies just hit different, you feel them rather than heat them and in movies especially there’s instances where you can sense something is going to happen by the way it pressurises the room (and that’s with just one 15” sub! Car audio subs aren’t really designed to hit this low so it will be quite an shock when you first experience these even if you’ve been into 130/140+db car setups. There’s really nothing else for the money that gives as much bang for buck as the 15”.

The 13” has around twice the power but the sound signature of a 15” or larger is different. I personally prefer the sound of larger subs but the 13” & 16” subs are absolute beasts from what I’ve seen and read.

@@MATechRU-vid I’ve read that the actual size of the 13” monolith is 15” due to monoprice not taking the surround of the driver in to account. So the 13” is actually 15” and the 16” is actually an 18”z could you measure the driver to see what the actual size of that 15” is? Thanks in advance

My 15” measures around 13 3/4” for the foam and 15” to the edge of the surround on the face (including the face with the screws) so measurements will be slightly different depending on the thickness of the foam anyway. The 13” and 16” in particular were produced to compete with the SVS subs and other flagship subs and likewise the power output is also much greater hence the higher premiums as they have twice the rms output from their amps as well. Either way you’re getting sub 10hz in room performance and I can speak from personal experience that even a single one is quite substantial but if you can balance a room out with 2 or more (further down the line) then you won’t be disappointed. I’ve spoken to quite a few people about the monoliths and the one thing everyone says is the performance blows them away.

I would take the 13 over the 15

If your budget allows I’d suggest buying the best sub you can afford and then add a second later down the line, that’s what I’ll most likely do with my 15”

If you already have a Klipsch then I’d probably say matching up would be an easier step for you however I can’t speak highly enough of the Monolith considering the price to output level. I personally was looking to add a second 15” to my setup to take it to 7.2.4 but in no rush for now.

@@MATechRU-vid I know, I would like to have it Klipsch all the way around, I already do for the most part, but the Monolith 15 is on sale right now for about the same price as the SPL 150 (I’d jump on it right now if I were you) also what are you thoughts, the 150 has an “LFE” option as the monolith doesn’t, is it more of a pain to have to adjust the crossover settings for the monolith? I don’t really have much experience doing so.

The Monolith has thx mode and is a certified thx subwoofer so it results in incredibly clean bass at refence levels. I leave the sub on thx and then do all the adjustments via my Marantz as opposed to on the sub itself.

The monolith is worth the upgrade

The SPL-150 is good but not great. Can’t dig deep like the monolith. I have both subs, they don’t comare

Yes but watch the video I made on it as I explain the limitations of this workaround in that.

It won’t transfer correctly on RU-vid so you wouldn’t get much out of it, the video would also get copyright striker most likely and get removed 🤨

Plan is to do the review on there 15” v2 first and then see where we go from there, Will update in due course.

@@MATechRU-vid Awesome. Do what you do, man. 👍🏼

My 16 comes in Friday!!! Yay!!!

Be sure you have some help lifting it because it’ll be a heavy thing 😳 I’m hoping to get my hands on the 16 somewhere down the line.

@@MATechRU-vid for sure, says it's 267 lbs shipping weight ! I'm dead

No issues, I do get some interference when it’s idle occasionally but a power cycle fixes it What issues are you referring to?

bad board/amp red & green flash. from some people on some of there sunwoofers.

No, nothing like that. I leave mine on all the time with it auto switching, it usually takes a few seconds from when it detects a signal and then switched on. Works every time without any issues.

@@MATechRU-vid im glad yours works great , im waiting on my replacement soon. thanks for the reply back.

Where are you based out of curiosity as I’m in the UK and the European branch is now closed so wondering whether a replacement means replacement amp for you or entire subwoofer?

They are impressive.

It was provided for review by Monoprice but would usually cost £1699 without any discounts added,

Thanks 👍🏽

What was your reasoning? Budget constraints or unhappy with the SVS?

@@MATechRU-vid I was unhappy with the sb16. I was looking that chest pounding bass. The sb16 did not impress me for movies.

The ported sub gives you more options, when setting the Monolith up if you do it in thx mode it’ll give you around 12db (in my maramatz anyway) that you can boost the bass as well as being able to further increase the gain manually as well. Since setting mine up with my SR8015 I’m super impressed by its performance , deep right and tactile bass that kicks hard without being too boomy even with 1 port open.

@@MATechRU-vid I’m definitely super excited now. Just waiting on these boys. I have the marantz sr8015 also. Definitely the best AVR I’ve owned so far.

I have svs sb 3000 and today i ordered monolith but i was also wondering about sb 16 ultra

Since when has the size of a room decided whether it’s a home theatre or not? For me it’s a home theatre when it has audio/visuals or both that make you want to watch content for the sake of watching to experience it in that space. My room is around 5m x 3m x 3m for context, and I’ve seen many a “home theatre” setup in spaces smaller than mine.

@@MATechRU-vid There is no definition of what a home theater size constitutes it being called a home theater. It could be a closet for all I know. However, there should be some modicum of a definition of a space that can account for what you are presenting as a 15" 1k watt powered sub in a space that is 5m x 3m^2 as a review for a fair representation of the acoustic prowess of a sub that big in a room that small. I mean, would your review be a fair one acoustically of a sub of that size? You even admit in your video that you can't capture the sound it produces and put it in the video. Is that really a fair review?

Fair to what extent? Measurements will differ from room to room anyway so all that’s left is personal opinion and I can share that regardless of the size of the room. I have been doing a lot of diy around my house this week and had the door removed which meant the sound was travelling all around the hallway and upstairs rooms which makes the space much much bigger and it was still able to pressurise the space and that’s what matter when it comes to the kick you want from content. I also think you’re missing the point as my whole home theatre series is for those who want to make use of spaces they already have and maximise what they have rather than force people into a minimum spec as you seem to be suggesting of minimum sizes and shapes of the room. As for the sub Monoprice have their specs listed on the website itself in controlled spaces and most people who’ve used REW fine they kick lower and harder when in “home theatre” environments so if anything they’ve been conservative with their readings so yes I do believe the sub has the prowess I’m suggesting. I have some shorts videos on my channel that may show how hard this kicks a little better as for the unboxing I didn’t dare turn it higher as it was shaking everything on my house.

Let’s hear your definition of a “home theater room”.

Joe - is that for me or methadras?

The 15” is V2, the 13” and 16” are completely different beasts and thus are capable of handling much higher power levels. The 13” and 16” are made to compete with the likes of the SVS pb16

@@MATechRU-vid but there are 2 15", boyh of them currently at the same price. One is v2 and the other isnt. Whats the difference?

V2 has rounded corners and slightly different design of the cone, V1 has the sharp edges to the box. As far as I’m aware there’s no difference performance wise.

I’ll be getting a second one next year to help balance out the front soundstage, I need to make a custom media console so will purchase the second one once I’ve built it. Do you have them opposite corners or both at front in your setup?

.

Maybe try watching the video and you’ll see why. Also I have tons of newer videos that show what my actual setup is rather than the temp one I used at that time for testing.
