Wow, these were really close! 1dB will not be noticeable by most people, usually takes closer to 3dB to be able to "hear" the difference. Either way, fun and educational video. Great job!
Running different size subs in the same box is the main concern possibly blowing out the weaker subs. Now if in separate boxes with different tuning you will cover a broader/larger frequency range which can help in a SQ setup.
A lot of people with this exact idea in their mind could benefit from being subbed to your channel. I remember seeing this kind of question with 2x10 vs 1x12, and 2x12 vs 1x15, whether on the old forums or on FB groups. I enjoyed this video. I think for some it could boil down to their trunk and whether they want to sacrifice the length of their trunk and have a slimmer depth with a pair or have a square shaped single sub and still have half the trunk, or the height of a single 15 wouldn’t clear the trunk
I have two 15” DDS SKAR subs couldn’t fit in my Caddy. Had to buy one single 12 tube by SKAR. Sounds loud and good but not the same. The 15’s not only sounded better, you actually feel the shaking of the subs and the car vibrates as well. The 12” woofer sounds good but no feeling behind it. 😢
Great comparison Parker. Quite a few people have asked me this question over the years. One major advantage to a single sub is needing less power, equating to no need to upgrade charging system, which is a big expense.
It all comes down to driver sensitivity response. It seems everyone (these days) equates a huge motor and stiff suspension to a BETTER driver.. and really if you want to get loud w/o upgrading you charging system, you need 1) and efficient amp that has a low distortion factor, 2) a SENSITIVE sub that matches the output parameters of that amp, 3) a complimentary enclosure that works with that sub to reproduce the type of result you are going for. What a lot off people fail to recognize, is you can have LOUD bass response in a relatively low bandwidth range, OR musicality in a wider range of response, but you are going to lose that little range of boost where you would be tuning that boost. Soo many times i built an awesome setup, only to find that some songs just made ya tear up with how great it sounded, but play a different track and it sounds like a kid whacking a bucket with a stick
I wish you would have tested the difference between 25hz and 30hz. I wonder if the 15 would substantially pull ahead the lower you go in hertz. One or two decibels in basically a tie on the daily. Thanks for the vids.
Love the content...so many people have these questions daily and it's so hard to find answers. A lot of times it's expensive to experiment. It's so much easier to look up a video with real-world results. Keep up the great work and bass on basshead
When I had my sub setup was running a single DC Audio Neo Elite 15" on a Dc Audio 5k soundlab in a ported box. It was awesome, had to upgrade the alternator, ran an extra yellowtop in the trunk, ran 8 guage from sub to amp & 2 guage throughout the vehicle. Could only bump hard for 10 mins before needing a cooldown 😢
I run 1 15 in an angled box since I have a sedan and trunk space is needed for groceries and it’s perfect, bass is smooth even when hooked up with a 1500w amp
I know this is mostly about SPL, but what about SQ? I realize that is subjective, but if both setups "perform" similarly, and one sounds noticeably better... buying the better SQ setup is a no-brainer... all else being equal. edit: typo
I have 2 sdr 12 on 1200 watts and my buddy at work has 1 sdr 15 on 800 watts. He wants to upgrade to an Evl 15 but I know he will get better results by getting a bigger box. This proves it.
Yeah evl sound better than svrs but realistically elvs are not mych louder uf they are even louder than svr. I ran a single evl and it was even that loud but it sounded amazing and shook my car to hell and back😅
Yes please get some 18's on the channel, doesn't matter what you compare them to just wanna see your overall thoughts on the 18in woofer if it is worth spending extra money and sacrificing extra space for a bigger box or should you just buy 2-12/2-15 instead 🤷♂️
I know they say not to mix sub sizes! but I like a hard punch of two 12’z, but I also like the deep bass of two 15’z too. So I like the best of both worlds at the same time! I’ve ran both at the same time before and sounded really good as long as u tweek it lol
I learned this the hard way. For decades I would only run 2 subs. Later in life I needed the space more than I needed the sound. I found out the loudness seemed about the same. I went from 2 10's to a single 12. Now I have a single evl 15. I would advise against the SDR's as they are junk in my opinion. The evls are clearly better than the Kicker solo's from my expereince. I would choose the Comps over the SDRs as well.
I did all these things when I was young not knowing what the heck I was doing and always got good results my systems sounded better than guys who get big bucks at car shops😊😊😊😊❤
Two evl 12s will definitely out perform 1 evl 15 lol. Make it fair an make it a zvx 15 :p Still really want to see you review the hooligan18 15"... Great video as always! Much love from Seattle!
I would like to see 4 cheap 12s vs 1 expensive one $300-$400 vs 4 $75-$100 surface area surface area average it’s about 75 square inches for a 12 and about 125 for a 15
I wish you would only show practical uses of the subs like running at rms. I’d love to see 2 12 vs 1 15 bug running that their rms only then matching rms then maybe 2 ohm 1000w vs 4 ohm 500w
Putting 5k watts to SDR that are only around 600 watt RMS each. The 15" is around 1250 watt RMS. Should be using the same line up. Not a low end to a higher end
That 15 is in a small box .I'm guessing the kicker box is at the lower part of the space that 15 needs so are the 12s at there lower cube space? Still interesting. Thanks for the video.
Interesting. Most subwoofer companies I’ve seen. Now this is based of doubling box cubic volume for a second subwoofer. For instance, Stereo Integrity sql 12” wants 1.5ft^3 for each so it would be 3ft^3 total box volume. But they want 4.25ft^3 for only one 15”. So it would be a a MUCH bigger box with just one 15” vs two 12” subwoofers
When I first went from my 2~12 inch U series sundown’s to 1 15 inch Xv2 there was a huge difference and I just change the baffle on the box so it’s the same box
2 12's might give you a bit more quality because of stationary waves and less moving mass, the 15 might get you a little deeper but there are so many other variables only way to find out is to try it ..
This is said frequently but in reality nobody can tell if they're hearing a 12 or 15 plus you can shape the sound as you want with your box by using either a 12 or 15
I’m not like most. I want the punch and musicality - don’t care about db’s. I screwed up. One forward facing twelve in a sports coupe. I should have done 2 x 10’s rear facing.
So, I'd say in the real world no ones going to have 5k watts to play with. If you have a quality amp thaty can output at 1ohm, then you will see a better performance from the 2-12's in series.
I'm not knocking this comparison. It's valuable content. I will just add another factor, which is subwoofer SD. The SD is the actual surface area of the woofer, and it varies from subwoofer-to-subwoofer. So, for example, a Sundown SA-12 V3 has an actual surface area of 67 square inches, rather than 113.1 square inches. Or, to compare Skar subwoofers: A Skar SDR-12 has an actual surface area of 73 square inches. A Skar SDR-15 has an actual surface area of 116.9. So, the difference between the two is 43.9 square inches. Not 63.5. Just to be a little more precise.
I know a guy who had a ma audio 4400 high current 2 channel amp and a 08 Memphis mojo 15 in a trailblazer. You could here it from blocks away all deep and loud bass hitting harder that almost every body that had sounds in the hood. He probably was doing 145db on rap music
Hey Parker have you ever thought about doing the gravity subwoofers? The G series. I would love to see you test a gravity g7 15" they look like the Trinity M18S but with direct leads.
Hey bro this was a dollar for dollar comparison but I would like to see a watt for watt comparison namely let’s say a 2000 watts rms 15” vs 2, 12” 1000 watts rms subs of the same brand …let’s see how that sounds using same wattage and same final ohm rating …

Yessir! Thank you Big D!
@@ParkerTheBassheadpause
😂😂😂😂
A 3db gain doubles the spl. 133 is twice as loud as 130db. But for a human ear to perceive a doubling of volume it requires a 9db gain, super odd!😊
look at the watt difference 450 watt
Run all 3 and see if you actually get more or not. Everyone says don't mix sub sizes.
I agree
You can mix but you should run off different amps because the tuning will b different between sizes
My friends and I have been mixing sub sizes for years running all on the same amp and in some cases in the same box and never heard any complaints
If he runs all three it will be like running 1 15 and 1 18 he will definitely get gains
Running different size subs in the same box is the main concern possibly blowing out the weaker subs. Now if in separate boxes with different tuning you will cover a broader/larger frequency range which can help in a SQ setup.
Love this video. Nobody does content like this. What people actually want too see. Keep up the good work Parker 🎉

Wow, Great comparison test. The 15" gives close to the same output if not more for less power consumption.
Which sounded better, that’s the real question dude. Awesome video man keep bringing the content 👍
This also shows you that the 15" took less power and gave out more spl than the two 12s also i like the fact that you kept them in the same brand
I have two 15” DDS SKAR subs couldn’t fit in my Caddy. Had to buy one single 12 tube by SKAR. Sounds loud and good but not the same. The 15’s not only sounded better, you actually feel the shaking of the subs and the car vibrates as well. The 12” woofer sounds good but no feeling behind it. 😢
Here in South Africa we actually have Toyota minibus taxis with six 15 inch subs on a daily😵💫
Great comparison Parker. Quite a few people have asked me this question over the years. One major advantage to a single sub is needing less power, equating to no need to upgrade charging system, which is a big expense.
Two subs would be much more efficient. Meaning they would be louder with less power.
im pretty sure i saw 5000w you def need to upgrade your charging system to handle that
It all comes down to driver sensitivity response.

I run 1 15 in an angled box since I have a sedan and trunk space is needed for groceries and it’s perfect, bass is smooth even when hooked up with a 1500w amp
I want to get 1 15 sub what is a good one to get and I have a Honda civic
LOVE THE SCIENTIFIC TYPE VIDEOS!!!! Went with 1 good 15" this time but I definitely plan on doing some more experimenting for the summer
Should have done one 18" vs two 12"s since the total cone area is closer to the same.
Parker those 15s have a undersized magnet and motor. 12s all day.
2 basic 12's are equal to 1 good ass 15"? That's what I'm getting from this.
I know this is mostly about SPL, but what about SQ? I realize that is subjective, but if both setups "perform" similarly, and one sounds noticeably better... buying the better SQ setup is a no-brainer... all else being equal.
edit: typo
Crazy how close the results are.another good video bud
I have 2 sdr 12 on 1200 watts and my buddy at work has 1 sdr 15 on 800 watts. He wants to upgrade to an Evl 15 but I know he will get better results by getting a bigger box. This proves it.
So basically 2 12’s of the same model would be much Louder. EVL’s sound way better than the SVR’s
Yeah evl sound better than svrs but realistically elvs are not mych louder uf they are even louder than svr. I ran a single evl and it was even that loud but it sounded amazing and shook my car to hell and back😅
Let’s see the 2 12 evl. For a better comparison
Yes please get some 18's on the channel, doesn't matter what you compare them to just wanna see your overall thoughts on the 18in woofer if it is worth spending extra money and sacrificing extra space for a bigger box or should you just buy 2-12/2-15 instead 🤷♂️
I would love to see a video of 2 Skar EVL 6.5 vs 1 EVL 8, 2 EVL 8 vs 1 EVL 10, etc. and would be willing to donate some 💵 towards the tests
12s gone hit harder then 15s just looking at the numbers let’s goo
Can you see about a really high quality amp on a cheap sub vs high quality sub with a cheap amp
That'd be interesting
Awesome test Parker!!
This video should help a lot of people out on decisions!
An EVL to EVL full comparison would be better. Thx
I know they say not to mix sub sizes! but I like a hard punch of two 12’z, but I also like the deep bass of two 15’z too. So I like the best of both worlds at the same time! I’ve ran both at the same time before and sounded really good as long as u tweek it lol
I have a 2 12 and 15 setup now, and I love it
@@toneyellison2102 same amp or seperate?
15” is more efficient for essentially the same dB. Less power and more equal across the frequencies.
I learned this the hard way. For decades I would only run 2 subs. Later in life I needed the space more than I needed the sound. I found out the loudness seemed about the same. I went from 2 10's to a single 12. Now I have a single evl 15.

What do you think about the SVRS
I thinks 8's are becoming pretty popular. How bout a vs's with 8's & 10's
I went with 8s instead of 10s or 12s in my wrx hatch and I couldn't be happier. 8s have come a loooong way over the last decade.
I did all these things when I was young not knowing what the heck I was doing and always got good results my systems sounded better than guys who get big bucks at car shops😊😊😊😊❤
I'd really love to see 1 18 vs 2 12s. Or maybe a couple of 10s compared to a 15?
a single 18 vs a pair of 12s makes the most sense
curious to see if sealed would make the difference larger or not
I’m interested in seeing the 2 EVL 12 test
They have a triple EVL 12 option too
Grab the triple 8 skar preload box and do the same test. Curious how that stacks up, I have heard the triple 8 box from skar can get into the 140s.
Thanks for clearing that up
Two evl 12s will definitely out perform 1 evl 15 lol. Make it fair an make it a zvx 15 :p
Still really want to see you review the hooligan18 15"...
Great video as always! Much love from Seattle!
This stands true to what I have always read and thought myself.
Damn I have been brainstorming about this for my Colorado...
I would like to see 4 cheap 12s vs 1 expensive one
$300-$400 vs 4 $75-$100 surface area surface area average it’s about 75 square inches for a 12 and about 125 for a 15
I would love to see how much power 2-evl 12’s can handle !🤘🏾🤘🏾🤘🏾
For a daily driver it's hard to beat one 15" imo. If I'm trying to get musical I just go with 10's
These are cool videos. I’m currently going with 1 15 over the 2 12
Going to 2 12s from 1 15 myself looking for a little more sq than spl
@@thomasnygard2334 2 12s are more musical. sound good on all music
and gets louder
I like the idea of running them all at the same time and seeing the results
I wish you would only show practical uses of the subs like running at rms. I’d love to see 2 12 vs 1 15 bug running that their rms only then matching rms then maybe 2 ohm 1000w vs 4 ohm 500w

I just got done building a sealed box for 3 SQL 12s .7 cubes each and they will smack your face off, omg what a setup😮
I love that dual 12inch box planning on a new build think ill build something similar
Also out of these 2 setups in the video, what sounded the best to you parker?
I'm a DD man through and through but deaf bonce subs are fucking mental 👌🏻❤️
b2 audio👊👊👊👊👊👊👊
2-Dc audio level 3 12’s build recommended enclosure straight from their website. Port facing passenger side of tailgate.
Of course I have the 2 12” faced towards me! and the 2 15” faced towards the back hatch!
Great video thanks for all you do for the bass community.
When I first went from my 2~12 inch U series sundown’s to 1 15 inch Xv2 there was a huge difference and I just change the baffle on the box so it’s the same box

Love how you testing out stuff like this😃🙏
A video we've all been waiting for 🤪🤪🤪🤪 Love from South Africa
i cant tell if his facial expressions are genuine or if hes constantly trying to focus in on what hes looking at
You get the right woofer in the right box it will out decibel anything, like the time I seen an 8 hit 136 decibels
Yea a 18 vs 2 12s is a good question around the same price ofc
A full EVL test is needed!
Yes, please run the same subwoofer.
youve come a long way my audio hatchling
So, I'd say in the real world no ones going to have 5k watts to play with. If you have a quality amp thaty can output at 1ohm, then you will see a better performance from the 2-12's in series.
I was scoping that 15 not too long ago, i bet it bangs!
Can you make a video of 2 15s wired to a taramps 3k bass and tuned
Having both 12s in the same chamber working as 1 makes a difference also
Should’ve done evl 12’s as well.
guessing 2 12's will be louder over 40 hz and 1 15 with stronger motor will play louder under 40 hz
I'm not knocking this comparison. It's valuable content. I will just add another factor, which is subwoofer SD. The SD is the actual surface area of the woofer, and it varies from subwoofer-to-subwoofer.

So, the difference between the two is 43.9 square inches. Not 63.5. Just to be a little more precise.
So that was a tie. I think custom boxes would be a better test
I’ve always wanted skar but all I got is a power acoustic gothic lol
Which one SOUNDS better??
That's why I went with 2 Xv3 12's. I couldn't fit anything bigger. Only working with 17 inches of height🤷♂️
Would 7 -18 inch subwoofers be louder than 14-8 inch subwoofers?I gots to know!
this video was perfect thank you
I'll stsy with my Mojo 15's. Thanks for the upload
Thanks 🙏 for the video. We learn so much from ya. My 8 year old BrodyMan listen to what ya say.
I know a guy who had a ma audio 4400 high current 2 channel amp and a 08 Memphis mojo 15 in a trailblazer. You could here it from blocks away all deep and loud bass hitting harder that almost every body that had sounds in the hood. He probably was doing 145db on rap music
If u keep it simple 2x12=24.. vs 1x15=15 cone area is key. I had 3 10s sound like 2 15s, got asked if I had 15s many times
Hey Parker have you ever thought about doing the gravity subwoofers? The G series. I would love to see you test a gravity g7 15" they look like the Trinity M18S but with direct leads.
@parkerthebasshead384 this is real?
Do sealed 1 15 vs 2 12 both in speced sealed boxes. Can also analyze the sound quality or what bass each setup hits better. Thanks great video.
I'm not for sure, but I think he's one of those bass heads that don't do sealed😂
Best system I seen thats cheap and can do high bass and low bass is 2 10s and a 15 on 1000rms at 2ohm
What about two sealed vs 1 ported same subs
Wouldn’t dual 12s be closer to one 18?
I'd like to see the difference between sealed and ported boxes of the same size
You should do a video on the mtx terminator kit see what kind of db read you get off them
I'd like to see multiple Subs hooked up to one amp with different ohm loads for each sub
Hey bro this was a dollar for dollar comparison but I would like to see a watt for watt comparison namely let’s say a 2000 watts rms 15” vs 2, 12” 1000 watts rms subs of the same brand …let’s see how that sounds using same wattage and same final ohm rating …
Do more smaller subs play lower than a larger sub? Everyone only seems to talk about spl.
