10 vs 12 vs 15 vs 18
Sealed/ported

Can someone explain the difference.in sound quality between the different sizes. And keys assume they ate all from the same maker, sealed and or ported.

With 15/18 do you lose the mid bass of the 10/12?
Is it really possible to mixed different sizes perfectly?

Ok first sealed vs ported. Both have their pros and cons, and it is subjective to a point cuz everyone likes something different. Ported subs can get louder and lower more easily and with less power than a sealed sub. But sealed subs are sometimes claimed to have more accurate, tight, punchy, quick bass.

The size of the driver really doesn't matter for accurate bass its all the other things that go into the sub that contribute to that. A 10" sub can't move as much air or hit as low of frequency as an 18" sub with the same size amp. So if your into sub 20hz bass for movies for example I would recommend no less than a 12".

That's a difficult question to answer. If the subs are made correctly by the same manufacturer and are in the same line, then they should all sound the same. The advantage will go to the larger subs. As volume increases and frequencies drops, the larger drivers will need to move less to produce the same frequencies and SPLs as the smaller drivers.

Low frequencies require air displacement and the larger the driver, the more air it can move. The less the cone has to move the less you will have distortion. All things being the same, it would take two smaller drivers to equal (slightly surpass actually) the air movement of the next larger drivers. So it would take two 10" drivers to get slightly better performance than a single 12" driver.

Ported boxes are slightly different as the larger the driver, the lower it can be tuned. Other than that, all other things still apply.

That all depends on the individual driver specs. There are some 18" drivers that do better than some 10" drivers in mid bass as well as the lower frequencies.

It can be done successfully, possibly perfectly, but it may require $$ and DSPs.

I think if you post the drivers/subs you are considering you'll get better answers. If these are raw drivers you plan on building yourself then you may get more answers if you asked int the DIY forum instead.

Thank you.
So im wondering if the 10 will hit a higher hz than the 15? Will it play nicer at a higher hz for more mid bass?

That really is dependent on the driver (material and weight), also the size of the cabinet and the size of the ports or passive radiatiors if its a bass reflex design. There could also be high pass and low pass filters which limit the freq resp too usually to prevent harm to the sub driver.

For instance my Outlaw Audio LFM-1 Plus subs (12") are spec'd at 18hz - 180hz +/- 2db 1 port open, and 25hz - 180hz +/- 2db 2 ports open. And and Elemental Designs 12" A2-300 is spec'd at 18hz - 100hz +/- 3db.

There is much more than size of drivers that determines output

If you are looking for a subwoofer just give a budget and type of listening you will listen too

The Epik Empire has amazing mid-bass videos

I'm not currently looking for a sub, I just picked up a hsu vtf15. I'm more about understanding the different sound produced by the different size subs. And I understand every like thing would matter but to keep it simple, let's say they were all the same except for speaker and box size.

I just recvieved the 15H also and think I know exactly what and why you are asking. These were my primary questions before I bought the 15H as I had reservations over a 15" over say a 12" (svs ported) as I wanted tight punchy midbass. The 10's and 12's HOME audio I've typically heard have all had a tighter punchier type of bass (kind of a dooh dooh) vs a little more of a boom but everyone said how much midbass the 15H had and put me at ease before it arrived, I still have the same questions now though. I've still yet to get measurements on mine vs. my 10's and 12 for comparison but I know what I'm hearing is less of a tight thud punch in the chest (what I thought I was calling midbass). Curious to hear the answers as well.

In my experience from car audio the 10's and 12's were always a tighter much punchier midbass, vs a
15" or 18". My listening preferences and reference music was rock and metal, as in metallica, ac/dc, megadeath, some some slower rock like van halen, bush etc and stuff like that with fast, tight, accurate, clean, responsive bass. Woofers were JL Audio W3's and W7's pushed with PPI and Zapco (basically the lowest THD's in the industry), and are cleeeaaaaan, with mids/highs Mb quarts (all competition components) so I know what cleanliness is and what I'm listening to. Not the BOOOOOM that the teenage gangsta is playing as he pulls up next to you distorting like crazy.

Thank you. That's exactly where I was going with my question. I think the baas is extremely low and the lower actually the quieter it gets. Are the 12s or 13s perfect?? Well they don't have what the 15s have.
can I have my cake and eat it too with a separate EQ???

Hi guys, First off don't confuse car subs with home subs. Sometimes home subs take a lot more effort to get them setup correctly. You should both post in the VTF-15 thread and ask the Dr if he can help you fine tune your subs. Also what takes some getting use to is the Hsu subs have very low distortion where the smaller 10s and 12s home subs have higher THDs and that is sometimes preceived as more bass.

As others mentioned you just cannot focus on woofer size alone. But the smaller subs that can hit hard and low do tend to cost more to get there. For instance, using the aforementioned Hsu 15H as an example, the only other commercial subs with a smaller woofer that can beat it are the SVS PB12+ and SVS 13 Ultra. And both of those cost considerably more: The Funkywaves 12x would be up there as well:

Yes a home sub has alot more air space and interesting floor plans to deal with. I'm really interested in someone explaining the different sounds of the sub sizes. And can a eq adjust the sub sounds as to get more mid?

This has nothing to do with car audio (I knew I shouldn't have even posted that comment.... please forget car audio existed in this topic), I was just stating that was my prior experience to home audio which I've had different subs for 10 years now. Furthermore this really isn't a question about the 15H persay but more speaker size and relative midbass punch to according sizes.

Sorry for posting Salty, I may have just de-railed your whole line questioning and premise for posting this by trying to ad some clarification. Maybe we shouldn't have even posted the brand name LOL rather a 15" X. Sorry.

Ok fair enough...what were we talking about?

It is how the box or cylinder and the amplifer is designed around the driver that really makes the difference.
