Monoprice Monolith M-215 THX Dual 15 inch Subwoofer |Unboxing, BASS Test & Overview

[@MiddlePark]

Installed a pair of these today (4x15") in my cabin home theater. These blow the monolith 16's away that I had before. I am kinda a bass head, and feel these are overkill, I love it! They are on a concrete slab and still shake the ground. The pressure at low hz is a new experience, highly recommend!

[@ThatHomeTheaterDude]

i thnk they have power but in my experience the THX mode did not sound great in my room. other than that, it was a sweet sub

[@Dat_Sun]

@@ThatHomeTheaterDude After some time with them, I find myself using thx mode 90% of the time. When I want them to flex, I use extended mode, but I can only take so much of it, after 30 minutes I get beat down as drywall dust rains down on my subs and nails back out of 2x4 framing in the basement. Had to use dedicated 15a circuits as the pair was tripping a single 20 amp 12/2 30' run circuit. The ports move huge amounts of air, so much it can spook you during a suspenseful movie. Aside from having 2 warranty issues (taken care of my Monolith, zero cost), I really enjoy all 460lbs of them. I noticed, placement of these is Huge, against the wall was no good for me, both subs are almost 2' away from the walls in my room to sound right. Music needs to be rebassed to really enjoy these to their potential in my opinion, easy to find though.

[@sebastian7539]

@@Dat_Sun how would you recommend rebasing the music to fully enjoy them? I have a pair of monolith 16s and they’ve disappointed me for two months while I try to get them dialed in

[@Dat_Sun]

@@sebastian7539 I use KZbin premium, there is hundreds if not thousands of rebassed and LFE music available to download. I had a pair of monolith 16's before these. Both malfunctioned at separate times in different ways. It's on my other channel Granby Homesteading. I was unimpressed with the 16's. The M215's blows the 16's away, at double the size.

[@sebastian7539]

@@Dat_Sun Sorry to hear that. Hoping the same doesn't happen to me. Mine only had a configuration issue which I've now sorted out. ​All they needed was a line driver for higher input voltage. I used the cleanbox pro and my Monoliths came to life! Much happier with them now, just wish Monoprice would've told me this and saved me tens if not hundreds of hours spent troubleshooting.

[@gregorymcgee100]

Putting them on their sides will actually enhance the bass a little I would think because both woofers are closer to the floor. And for even more bass put them in the corner of the room. Walls will amplify bass even further. One more thing-as far as bass goes-size matters!

[@theheadsn]

Something like this is ideal for people who have big spaces. Not saying theaters, but some of us have wide open areas. My living room is open to my kitchen and dinning room (open concept), so I have about 6000 cubic sq ft worth of air space to contend with. I was using a wimpy polk psw505 for ages and it was grotesquely under powered for the area. In the past year I finally got around to buying a SVS PC4000 which has completely changed the bass game in my house. That being said, I would kill to get a second one as well because even with the one it doesn't completely fill the space. Now this I could see doing a very awesome job of filling a space full of bass, my only reservation would be you would probably be better off buying two separate 15's to better help evenly fill the space. Or you could just buy two of these lol

[@hi-fihaven2257]

Love that excursion demo at the beginning of the video! That sub is a beast man, love the build quality.

[@Packer1290]

I don't really get the whole subwoofer crawl thing. I mean it sounds good in theory but if you like me and your home theater is your living room, there's not a lot of placement options for my 2 subs. Are people ending up with the subs in weird places doing this? Or is this just for dialing in small adjustments like how far from a wall or a few inches away or closer to a corner?

[@seangoodrich7177]

I have one M215, and just ordered a second one. Fantastic subwoofers.

[@sebastian7539]

Did you have to turn the gain up on these? I cranked mine all the way on the amp and then have in at -5.0 in my Denon receiver settings to get sufficient output.

[@Ashkablessing]

I have 2 of these in my dedicated theater. I also had to turn the gain all the way up and have my processor at 0- +2 depending on content. I feel like something has to be off for the output to be so low. Not thrilled but haven’t had a chance to call monolith.

[@Dr4x1983]

Nice video, an this 8 bit end-music is awesome, thank you. If you ever get the chance to test (or hear) a JL Audio Fathom® f113v2-GLOSS (or anything bigger like Gotham) do it! The frequency spectrum is a linear line (!) and I have never heard such a precise, dry and controlled punch. I heard this thing in a dolby atmos reference cinema in the 150.000 € class. It was absolutely amazing. We compared 1 Fathom® f113v2-GLOSS against 3 SVS PB 16 Ultra (in this cinema). Best scene was in John Wick part 1 the disco scene. No chance for SVS to win this, I could not believe this. The PB 16s have been so "unprecise" and "uncontrolled" against the Fathom I really can't describe it. If you have the chance try to listen to a Fathom or Gotham you won't regret it. Kind regards from Germany

[@MusclesAVS]

I demoed 2 fathom F113's. They have like 1/3 the output of a PB16 ultra at 20hz. They aren't very high output subs, they are good for their size though. Rythmik subs have more output, better sound quality and are cheaper. They basically made JL Audio subs obsolete.

[@C1000-c7b]

I'm surprised they didn't make the Xmax stroke more than 25mm with these drivers, so I guess that's 50mm in both directions. With that power wouldn't it be limiting on the excursions once the volume reaches high output on the sub 20hz frequencies. Looking at the REL NO.25 driver this has a 4inch excursion as well as some bass arrays that are used at gigs with 15 or 18 inch drivers which use the extra long throw excursion. How do the 215 Monoloths fair when your system pushes out 100db and over when the sub bass frequencies really hammer the excursion movement to the max. Either way, this is still a really cool Dual sub.

@@ThatHomeTheaterDude No, read carefully what I am saying. THX has nothing to do with it. There is nothing in THX certification that specifically changes anything. As I stated you almost always have to rerun Mic setups because drivers differ in sensitivity and plate amps differ in gain. In fact for amp certification THX required amps to have the same gain specs just so all amps would be compatible and easier to integrate into the rest of the system. This is a no brainer to introduce a systemic approach to system building.
