ONE 15 VS TWO 12 SUBWOOFERS | MYTH BUSTED

[@wal]

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!

Yessir! Thank you Big D!

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!😊

[@jacktheripper-hp9tx]

look at the watt difference 450 watt

[@trinilovaboi9699]

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

[@josephmuniz9959]

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

[@dominicdymond]

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

[@mrbig4423]

I agree

[@jackkight7771]

You can mix but you should run off different amps because the tuning will b different between sizes

[@MichaelJohnson-je2vo]

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

[@MichaelJohnson-je2vo]

If he runs all three it will be like running 1 15 and 1 18 he will definitely get gains

[@steveclark9934]

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.

[@TheBluuHouse]

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

[@chrisclawson296]

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

[@ponokanaka]

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

[@lifeofandrew701]

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

[@MrSzero13]

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

[@ParkerTheBasshead]

I appreciate it man!

[@csj9619]

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.

[@rationalguy2941]

Two subs would be much more efficient. Meaning they would be louder with less power.

[@salimsopari]

im pretty sure i saw 5000w you def need to upgrade your charging system to handle that

[@jimbobdobbs1597]

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

[@ronaldwhitt3691]

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

[@aidanafshar8744]

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 😢

[@Kwa_njayam]

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

Holy shit that bitch probably hits as hard as god doing a slam dunk

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.

[@eddisoncassius4994]

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

[@mrreggiej85]

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

[@1helidude]

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. 😢

[@TG-qy3us]

Crazy how close the results are.another good video bud

[@brockmarquis8511]

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.

[@SoberBassHead]

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

[@evilinside5984]

2-8s will be close in the 45 Hz, & up range, but not close in 40 Hz, & Lower, imo.

[@MrDopey32]

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

[@ditto_75]

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.

[@ndcpain465]

Yea u right hopefully he see this

[@jdextlab]

Those boxes probably aren’t tuned to hit that low so the subs will just lose control and sound like crap

[@RyanThomas-ux2rf]

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.

[@jerrymatthews1053]

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

[@jimbobdobbs1597]

​@@toneyellison2102 same amp or seperate?

[@MikeMik86]

Technically two 12s have more cone area, but since you went with cheaper 12s this results make sense. Another idea would be the old square vs round sub debate. Thanks for the videos! Cone area = pi x (r x r) pi = 3.14 r = radius of sub One 8" = 50.27 One 10" = 78.54 One 12" = 113.1 One 15" = 176.71 One 18" = 254.47 Two 8" = 100.53 Two 10" = 157.08 Two 12" = 226.19 Two 15" = 353.43 Two 18" = 508.94 Three 8" = 150.8 Three 10" = 235.62 Three 12" = 339.29 Three 15" = 530.14 Three 18" = 763.41 Four 8" = 201.06 Four 10" = 314.16 Four 12" = 452.39 Four 15" = 706.86 Four 18" = 1017.87

[@20smgreen]

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.

[@ADA513]

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

[@davidmarles9409]

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

[@kevinAuman1]

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 🤷‍♂️

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

[@jeffferguson69]

I think cone area for the win unless the 1 15 is on another level. Like way on another level lol

[@CrashPCcz]

Depends on the situation,but more overall coil mass, coil area, displacement volume, box volume, all that will rather win. Especially so when high end drivers scale poorly with price.

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

[@lolosolodolo1]

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.

[@PurpleSneeu]

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

[@ChannelZeroOne]

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.

[@ozzayyyy]

What do you think about the SVRS

[@evilinside5984]

The single 15" was Louder, than the (2)- 12", with less power @ every freq., below 45 Hz! Then @ 45 Hz the (2)- 12" were only 1/2 Db louder than the single 15", but it took 334 more watts to do so. The more fair, cone area wise comparison, would have been (1)- 18" D2 Zvx, vs (2)- 12" D4 Sdr's, 254 sq. In. Vs 226 sq. In. Of cone area. Put both in a 5 Cu. Ft. Net enclosure, tuned @ 30 Hz, with both having 70 sq. In. Of port area. This would be really Awesome to see!

[@belowme70-1]

Cant get around the fact that 2 12s displace more air than 1 15. 24" vs 15". Power ratings left aside ofc.

[@haelaqeeli9864]

Thank you for the excellent videos and help you always offer! Myself I would do 30hz and maybe 50-60hz tests, as I am seeing from your test the 12’s would be better for 45hz+ maybe say 60hz they’d be at 140db or so, below 35hz the 15” wins, so for 25-45hz get the 15” for 35-60hz get the 12’s maybe?

[@dirtysouthpyro1981]

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😂😂😂

[@myboy051]

Also depends on what you are looking for. What kind of music do you mostly listen to. Fast moving bass or lower frequency slower bass. If accuracy matters to you maybe the 12”s are a better choice. Personally in my experience, 15’s hit the low frequencies with ease and smoother than 12’s. Yes there are so many different variations. I have a SQ system. I run two 12’s in the back and one ten in the front footwell. 12’s produce the lower frequencies and the 10 gives me the fast accurate chest punch that compliments my 8” mid bass perfectly. Crossovers are Rear 12’s are 0-50hz Front 10 is 50-100hz 8” midbass 100-270hz 3.5” mid 270-3850hz 1”Tweeter 3850-20khz Use a Helix DSP ultra.

[@jyjyfleming5529]

[@ericwheelhouse4371]

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

[@danielowens9013]

I’m always thinking the other way would it be better with one extremely good twelve or two budget 15’s

[@marthepedersen1454]

but two 15 take up waaay more space/weight

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

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 ..

[@oscarishandsome5150]

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
