Epic Fail or Epic? Skar vxf 15" subwoofer review  

Thank you!

Thank you

Thank you!

They can definitely handle power. Very good subwoofers for sure. Thanks so much for watching.

That sfb 8k looks like a great amp! I'm running a t8000.1 trinity right now, but idk if it's capable of doing even close to rated, seems barely louder than the smart 3 bass I had on the subs before

Thanks so much!

Just got one but I can only feed it 1500 max

Thank you so much!

Thank you!

Thanks!

Definitely these subs are definitely do that.

Haven’t tried the HD yet.

The vxf is more accurate musically. The xr are great but a little less accurate.

Output wise almost identical because the smart3 counteracts impedance rise but the surge sounded warmer and more controlled.

Not enough for a pair of evl more less these monsters. I'm personally running 4 of these right now off 2 jp63. They love power

Yes out of all the subs I have ever had and tested vxf is one of my favorite subs.

Thank you

The VXF sounds completely different than the sundown x. The VXF is a more accurate punchy subwoofer. It will have more punch and slap I kick drums. They hit the lows very good but since lower excursion than the sundown X they don’t have as much air movement. Although I actually think the X if used the right box is a good sounding subwoofer for an air pump , high excursion type subwoofer it’s bass notes are so smooth that it lacks definition o. Tight bass compared to the vxf. But that’s where the x shines. It has no punch or slap so in bass music is flexes like crazy and sounds super smooth. So both have there places.

@HiFi Vector yes i think the x12 v2 is awesome on the low end, but i guess im used to to a normal sounding sub. My X is in a 2.5 cubic foot birch stained box tuned to 34hz.

I jus put the same exact ones in but my box is 6.5 cubes tuned to 31hz wired to 1ohm on the smart 5k bass and they get down

@EVIL INSIDE Thanks bro..yea I actually bought the 3k and sent it bck after Watchung many reviews of ppl saying they had the 3k and was upgrading to the 5k because the subs could handle more..now no I don't have it turned up plus I'm breaking them in (or atleast I think so lol) so that's why I got the 5k plus if I decide to go bigger on my subs I have the power to..

That would be a great setup. You could definitely feed it more than 2k if you wanted to get everything out of it.

At the time of the video 270 amp alt, big 3 and all ofc 1/0 power wire.

@@HiFiVector nice, I sure appreciate it!

You’re very welcome thanks for watching!

The prefab is this one. amzn.to/43qUTg8 It’s a good sounding 15” cheap box.

@@HiFiVector very good. Thank you.

What amp are you running? And 1 vxf 12” or 2?

@@HiFiVector mtx jackhammer jh10001 at 2ohm for 1 vxf12, but I'm ordering the Sundown 1.5 soon.

Since the vxf handle more power compared to the xr. If you give each 1000w yea the xr is going to move a bit more but give the vxf a little more power and it will be an animal.

Thank you! I love them both they are just very different sounding so it depends on your preference.

​@@HiFiVectorI wish I could buy both but unfortunately I can't at the moment so I'm looking for the best SQ.

They both have great SQ but the vxf is more tight and accurate. The RS is smoother but less punchy so they have a totally different sound. But i would say the vxf would prob be better for what most people generally consider SQ.

Thank you that's exactly what I was looking for

The XR is a great sub but it just depends on personal preference. They both hit the lows great and sound very good but the big difference is the vxf has better transient response and is more accurate musically. Other big difference is the vxf has more punchy bass where the xr is less punchy smoother bass that is a little less defined. They are both great just depends on what type of bass you like. I prefer the vxf personally.

I am going to pick up 2 12” and try them for sure. I was super impressed with the 15’s.

Sound quality is xlnt

The fs of the 15” model is 31.4 hz how in the world is that too high?😵🤣

@@elijahdossett3528 uh because it is? Grant it, it's on the low end for an SPL driver, but the majority of musical 15" drivers have an fs in the upper to mid 20's with 18's having an fs in the lower 20's or lower. Of course this does not apply to pro-audio drivers. We in the car audio hobby however are an odd bunch and want the best of both worlds hence the existence of "SQL" drivers, which is what I would say the VXF is.. 31.4 hz is an fs that I would find acceptable for a 12" driver. fs doesn't dictate everything, like all T/S parameters it's part of the trade-off of driver performance and efficiency. A 15" driver with an fs that high is going to need a much larger enclosure to be able to dig down into the mid and lower 20's than one with a more sensible fs of say 28 or 27. It's sacrificing part of the advantage that it's sd gives it for more SPL.

@@buddykillerthe fs of that sub negates everything you just said. Fs DOES NOT determine musicality, which is proven by how well this sub plays. Just like I build enclosures for the zvx 15. I have a customer with 3 zvx 15s in a 11.1 cube net enclosure tuned to 31hz that plays down to 18hz with authority and still meters a 153 @ 3,015 watts clamped. It’s all in the enclosure. Come on man. I have 600+ hand drawn designs to my name. 200+ of those are for skar builds.

@@buddykiller you try to nerd out, I can be an absolute nerd as well but when you get to the basics the fs of this sub for most 15” woofers on the market is lower than average.

@@elijahdossett3528 I don't try to nerd out, I live here full time :P You're misunderstanding me. That's why I said fs doesn't dictate everything, and that when you consider the driver's size in relation to it's fs it falls squarely into the SQL category. Did you read what I said about the 18" evl I owned? We agree on just about every level except what musicality means and how a driver's fs factors into that. You've got 3k pushing 3 15's, I don't doubt that can hit 18 hz with authority, but if your enclosure is tuned to 31 hz then 1) cabin gain is definitely factoring into that and 2) I promise it's either significantly louder or cleaner playing 30's compared to 18 hz if not both. Have you checked the waveform? I've never personally built or modeled for ZVX drivers and how well you can tune under fs and how far under fs you can tune depends entirely on the driver's characteristics. Unfortunately my real life experience is limited due to budgetary, location, and psychological restraints, but I model and design enclosures all the time for fun. I envy you, I LOVE car audio and would kill to do it professionally but it just isn't in the cards for me. I like peaky bass response, but I live for low end extension and in my experience response curves for most drivers start getting all wonky the further below fs you tune when you care about port velocity. That's why I fell in love with 18's and infinite baffle configurations. I can't wait to replace the sdr I have in my home with an Ultimax.... Or 4 >_>

Tapped horn in a vehicle?

@@csj9619 yes and they sound perfect when done right

The vxf hit low lows a lot better, have more excursion. The R3 is tighter and a little more musically accurate. But the price diff is huge between them.

@@HiFiVector so which would you choose?

I like both just depends on what you like if you want loud and crazy go vxf. If you want tight and clean and done want a big amp go R3.

Vxf I’ll save you future mistake!

@@got2getit204 I agreee with bro if you ask me the vxf is best bang for buck the sundown u is almost 200 bucks more that’s damn near another sub

These have better sound quality for sure but those xfl are good subs as well. I prefer the vxf.

Would you say the xfl 15s are louder and have more excursion

The xfl 15” are a little louder. Not by much though but the sound quality of the vxf is way better. But it also depends on the setup and the box of course but this is in general.

Thanks for you professional opinion! Have you tried the 15 NVX VCW154v3 ? I’m thinking of upgrading to those or the vxfs

I haven’t heard the v3 nvx 15 yet.

For me vxf hands down.

@@HiFiVector thanks man

You’re welcome thanks for watching

I prefer the vxf.

That is not an accurate statement

It depends if you have the extra power to give it. The VXF will handle more power and it will hit the Lowe’s better than the EVL.

@@HiFiVector with same power i wont hear/ feel any diff.?

@@slitherman7883 Yes you will hear a difference in sound but maybe not volume.

@@HiFiVector later i plan to upgrade frm sk1500 amp to a 2500 or 3k for my vxfhave you utilized evl and vxf

@@slitherman7883 Yes I have both EVL and VXF subs. EVL are slightly more accurate but the VXF has more excursion and hits the low notes under 33hz better. Bothe are great subs.

Yes they can for sure one of them takes the smart 3 just fine. After I had them for a while I threw the smart 5 on them and they did great.

That's exactly what I jus put on my 2 the smart 5k bass

They can handle a smart 5k per on proper loading and filtering.

I agree but that’s all I had in my truck at the time
