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!

Love this video. Nobody does content like this. What people actually want too see. Keep up the good work Parker 🎉

Run all 3 and see if you actually get more or not. Everyone says don't mix sub sizes.

Which sounded better, that’s the real question dude. Awesome video man keep bringing the content 👍

Thanks for doing a 15 comparison with two 12s. That's one of the things I've been thinking about.

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

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

LOVE THE SCIENTIFIC TYPE VIDEOS!!!! Went with 1 good 15" this time but I definitely plan on doing some more experimenting for the summer

Here in South Africa we actually have Toyota minibus taxis with six 15 inch subs on a daily😵‍💫

BEEN WAITING FOR THIS !!! love these type of videos AWESOME CONTENT PARKER AS ALWAYS !!!!

Awesome test Parker!! This video should help a lot of people out on decisions!

Wow, Great comparison test. The 15" gives close to the same output if not more for less power consumption.

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 😢

Exciting stuff, definitely would like to see evl 12's v evl 15. Fantastic video, pretty scientific stuff buddy 👌. Can't wait to see the one 18 v 2 , 15's maybe deaf bonce. Excellent experiment.

Crazy how close the results are.another good video bud

Thanks for clearing that up

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. 😢

Love how you testing out stuff like this😃🙏

I like the idea of running them all at the same time and seeing the results

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.

I’m currently running two of the Deaf Bonce SA-302’s love them so far. They slam and the sound quality is great

Great video thanks for all you do for the bass community.

I'm fixing to build a new system and this really helps me make a decision!

I needed this thank you🎉🎉

I would like to see 2 8s vs 1 12. Thanks Parker.

Great video Parker!!!

Pretty cool bud. Keep Bassin on.

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

A video we've all been waiting for 🤪🤪🤪🤪 Love from South Africa

Super test , continue comme ça 👍

Nice. I learned something. Thanks brothah.

this video was perfect thank you

Excellent video. Really good idea.

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 🤷‍♂️

Cool video, man. I would like to see a comparison of 4 8's skar evl's vs. 2 12 evl's

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.

I love that dual 12inch box planning on a new build think ill build something similar

I like that you did it within a dollar value, but yes, you should also do it comparing different sizes in the same line/level.

Damn I have been brainstorming about this for my Colorado...

Great Video keep up the good work

curious to see if sealed would make the difference larger or not

Great content nice power ratings

Great video dude. Ds18 ZXl 15. 30mm xmaxx been really studying this sub for some time. Price drop to 299 made them more appealing. Love to see you test them out.

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 was searching the Internet looking for a good comparison between a single 15" EVL and a dual 12" SVR loaded enclosure deal. Single 15" or a dual 12" are the biggest that I can fit in my trunk. If the (2) SDR are hitting as good as the 15, that means the SVR will be even better. Thanks for the info.

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'll stsy with my Mojo 15's. Thanks for the upload

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

This stands true to what I have always read and thought myself.

A full EVL test is needed!

Love a 15, i used to have a 15" Fosgate t1 on 1k powerbass monoblock in the trunk of a kia optima. Man that thing slapped.

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 the video. We learn so much from ya. My 8 year old BrodyMan listen to what ya say.

2 basic 12's are equal to 1 good ass 15"? That's what I'm getting from this.

Great video

Nice bro!

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 love to see you test some of the DS18 EXL-XX12.4DHE. They look like some pretty good subs by looking at the specs. They have a lot of Xmax compared to most subs out. I know that the HOOLIGAN subs have more, but they are more money, and they are sold out. I just purchased 2 of the EXL-XXX12.4 from Big Jeff. It will be a little bit before I get them hooked up though.

I would love to see how much power 2-evl 12’s can handle !🤘🏾🤘🏾🤘🏾

I'd love to see the same test in sealed enclosures.

Great channel. Would like to see more db testing, car loaded with luggage will this lower db reading. Also curious which direction I should take. Currently running 2 12in power t2d2 subs on fosgate 2500 amp. I only metered 140s. Would I gain more with more power on these subs or upgrade subs, I have considered doubling the power and using one amp per sub however manufacturer did not reccomend.

Also out of these 2 setups in the video, what sounded the best to you parker?

youve come a long way my audio hatchling

Would love to see one beefy 15" vs 2 weaker 15", would they be the sameish or would cone area beat raw power.

Should have done one 18" vs two 12"s since the total cone area is closer to the same.

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😊😊😊😊❤

2 Evl 12s vs 1 Evl 15 on the same power and then max power would be very interesting. Do it!

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

3 10"s vs 2 12"s vs 1 15", all the same EVL or same line from whatever brand(deaf bounce, sundown, incriminator, SKAR). Which setup gets the best bang/boom for your buck. Of course all 3 setups matched to cubic feet & RMS watts in the same vehicle. So for instance would 2 skar evl 10's hit harder than 2 12" evl's or 1 15"??? Or maybe swap the 15" for a 18" but not everybody can run a 18 so the 15 may still be a better choice. I'm trying to decide which way to go now myself. Im currently running a single Memphis mojo pro 12" in a skar 2.0cft box on a skar rp.1200 @4ohms(500watts). Im trying to figure my next move & running the 2 12's side by side wont work in my Acura TSX. So do i run 1 deaf bounce 3512 in a 2.65cft box, add another skar single box with another Memphis Mojo Pro or up size to a 15" skar evl in a 3.15cft box???? Im very happy with the single mojo pro but of course i want more bass😂😂😂

In terms of efficiency, the 2 x 12 s would be more efficient right ? In terms of heat etc

I’m interested in seeing the 2 EVL 12 test

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.

Can you do a review on the skar audio 3 8in ported enclosure?

What if you did the same test but with all the same size woofer? 2 cheap 12s vs 1 more expensive 12, even if it's from a different brand

yes please i got 2 skar evl 12s and want to know if i should get a 15 instead

What would be louder, 1 really nice 15 or my current 2 kicker l7s on 1500w rms?

What single Sunday will be louder then 2 skar evls 12

15” is more efficient for essentially the same dB. Less power and more equal across the frequencies.

That's very interesting! In theory thise 2x12 should have been louder, but they weren't. Very interesting!

When you say clipping is that the amp clipping or the subs bottoming out on excursion? If it's the amp clipping was the nominal impedence of both subs the same? Based on the impedence reading from the SMD it looked like the 12s were wired to 1 Ohm whereas the 15 looked to be 2 Ohm. That would explain the difference in power achieved.

I wanted to see all 3 !

These are cool videos. I’m currently going with 1 15 over the 2 12

I'd like to see a video that shows the difference between sizes and the type of music you like (aka BPM). I like fast electronica and have always been told to stick to a smaller size so they can respond to the faster BPM. But I ran 2x 12s for years and thought they sounded fine. Thoughts?

Can you see about a really high quality amp on a cheap sub vs high quality sub with a cheap amp

So basically 2 12’s of the same model would be much Louder. EVL’s sound way better than the SVR’s

I'm debating 9n going with 4 ab xfls 15s or 2 sundown xv3 18s

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.

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 was scoping that 15 not too long ago, i bet it bangs!

I'm curious to see what db you would have got at 50hz and 55hz aswell and 25hz and 30hz

Can you please do the same video except with one Skar zvx18 vs 2 Skar vxf 12s???

You should do a review on 12 audio legion maximus Review thanks

Are you running any bigger alternator or just the batteries

Sub in the background chilling and a monster

Should have used the same 15 as the 12s just to see how it stacked up.

Also was both boxes tuned to the same frequency?

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

What is the tone generator your using on your phone?

I'd really love to see 1 18 vs 2 12s. Or maybe a couple of 10s compared to a 15?

Would like to see a test on the resilient sound gold sub
