Well, chatted with someone from PSA, may have been Tom, didn't ask for a name.

I have been convinced to go ported and go through v1500 route as the output will be so much more than the f12 I had down low. It won't dig as deep (around 7hz) but that shouldn't matter anyway as long as it shakes me, the couch, and the foundation haha.

If it does not, than I don't know where to turn. V1800? V3600i? DIY with SI HST18S
The v1500 is free shipping both ways so its the safest option. Not taking anything away from its quality, it's just going to hurt to send the 66lb rythmik back on my dime.

I would go about 3" minimum. But it doesn't need to be much. I asked Tom about this when I first got my XV15 and he said 2" to 3" is fine.

With a widely flared circular port a good rule of thumb is half the diameter. In this case 4", so a minimum of 2".

@Rfitz89 if you are starting out in a corner you'll get plenty of boom. I like to pull it away from the corner along the wall 6" at a time and it usually smooths out the frequency response. There are plenty of sources for bass sweeps around including REW. You don't need a mic to use the Signal Generator or the Room Sim.

Now the waiting begins. I can still remember the day FedEx rolled up with my subs.

We discontinued the free return shipping policy a couple of weeks ago. The V1500 is going to crush the f12 over the entire operating bandwidth---which is no slight on the f12 of course its just a much smaller, sealed unit with about half the amp. I bet if you had one of each in the room you'd absolutely say the V1500 had better extension with action flicks that had serious bass <25hz. >50hz I'd guess 2x the headroom)6-7dB)..maybe more like 3x. <40hz is where it will get interesting...I'd say 4x maybe 5. 11-15dB. The overall sound quality will be similar.

The V1800 and V1500 perform more alike than different. The biggest difference is the V1800 having another 4dB or so above 30hz. That can be significant though. Despite a small number of vocal-locals who seem obsessed with 16hz sine wave wars a subwoofer is going to be largely defined by what it is providing >30hz rather than under.

The V3600i is a beast. I mean going from a f12 to the V3600i...might not really be a good idea. It would be like enjoying an *atomic fireball* and thinking "Hmmm, those Ghost Peppers sound scrumptious!

Quad v3600i's. Muahahhaha

It's a pipe dream. I have a feeling the 1500 will do me just fine. If not!, go big or go home, the 3600 it is, no more messing around haha.

Sucks about free return shipping. Barely missed it, oh well. Not too worried about it

Going from a 12" to an 18" means I can feel movies in the chair. It's a lot larger than a 12" so be warned. My wife was like what the heck did you order. It looks like a small fridge. LOL

REW Room Simulation

I have wondered how accurate REW's Room Simulation is and I figured I'd post this for future reference. Two sub guesses with combined (in black) and the actual results. Up to 60Hz makes a great case for dual subs.

I am not sure if I have posted my setup here before.  We're getting a new area rug in the living room and I was cleaning up the entertainment center and dusting all the speakers so I though I would post some pictures since it's all clean looking.  The large entertainment center is from Diamond Case Designs in California.  It's not a cheap entertainment center but is is very nice.  Hand made all birch wood with metal slotted shelfs.  I added in 2 Cooler Guys exhaust fans in the back.  I will have to get a couple more metal shelfs when I add in a 5 channel power amp at some point and an Xbox Scorpio next year.  So far here is the equipment list:
Samsung 75" UN75J6300
Yamaha RX-A2020
OPPO BDP-103
Playstation PS4
Directv genie
APC H15 Home Theater Power Conditioner x 2
Polk Audio RtiA 9's mains
Polk Audio CSI A6 center
Paradigm ADP-170 surrounds
Power Sound Audio v1800

Pretty happy with it so far but man you can tell a difference in sound without the large area rug on the hardwood floors.  We're actually adding a larger rug tommmorw so it will be interesting to see the effects it has on the sound. 
And window tinting is on the list of things to do.. LOL.

Understandable, though I'd personally would as it seems like more work to sell or trade in my XS30SE. I'd still have to pay a bit of money, and deal with moving two of your beautiful, but super heavy subwoofers. My movie room is located on my second floor and the thought of having to bring one down and then the other up is intimidating. Almost threw my back out the first time lol.

Need some opinions - my room size is effectively ~2500cu.ft with all the openings. Does it make sense to consider sealed? I was in chat with Tom and he said a 15v/V1500 would be fine, and for sealed I'd need to spend more and get at least a S1800/S3000i. I've never really heard ULF so I have no idea how it sounds like or if its worth it.

Table from this thread - Your Home Theater ULF Score



Based on this we see the V1500 is much more powerful than even a S3000i. Its not listed at 10Hz, but even at 12.5Hz it pulls ahead. Is this correct? Sealed subs are supposed to be better at ULF right?

No but I am looking for something with good WAF.. LOL. The worst part you don't see is the three large kitchen windows and 2 small kitchen windows by the sink that show up during the daytime horribly on the TV. I just do my movie watching at night but it would be nice to darken them up during the day. I may look into getting one to see how it looks and then possibly for the other windows later. Thanks for the link.

How everything seems to match up the way it did is beyond me.. LOL. Speakers were bought about a year before the entertainment center and floor. I ordered the entrainment center in January last year and then we decided to go from carpet to hardwood in April. Was originally looking at Hsu subs and then started reading on this thread and everyone changed my mind... LOL. I am sure the Hsu 15 would have been great but the V1800 is a lot better.

You're room is kind of in that sweet spot where you could go either way. But remember, to dig deep with sealed subs you usually need to spend more because you will need to get enough power to make that extension noticeable. I would think you would need to consider going with dual sealed subs right off the bat. That said I would go with the 15V or V1500. Actually I would consider the V1800 as well.

Remember this, the vast majority of movie material is above 20Hz and the amount of material below 16Hz is probably below 1% and the amount of material below 12 Hz is even less. And to make matters worse, the lower the ULF the more power it takes for you to notice it. So the real question you have to ask yourself is how much are you willing to spend chasing the small amount of material below 16Hz? It's a matter of the law of diminishing returns.

I believe Tom is implying for upgrading to a "I" which is a dual module 1700watt amp. However for a short stint there was a S3000 that I believe used a lower power Ice amp. So I am not sure if that is a possibility or not?

Based on this we see the V1500 is much more powerful than even a S3000i. Its not listed at 10Hz, but even at 12.5Hz it pulls ahead. Is this correct? Sealed subs are supposed to be better at ULF right?
Remember that is right around port tune...above and below that the 3000i is significantly stronger. Unless you were listening to cherry picked demo material that focused on 15-25hz, the 3000i will sound more powerful with most source content. As Hop you could go either way...I personally would lean towards the V1800 or 3000i.

Why doesn't the T18HT get more love from people here?

Because of the cost...most here do not want to shell out 3k for a sub.

I would think you would need to consider going with dual sealed subs right off the bat. That said I would go with the 15V or V1500. Actually I would consider the V1800 as well.

Remember this, the vast majority of movie material is above 20Hz and the amount of material below 16Hz is probably below 1% and the amount of material below 12 Hz is even less. And to make matters worse, the lower the ULF the more power it takes for you to notice it. So the real question you have to ask yourself is how much are you willing to spend chasing the small amount of material below 16Hz? It's a matter of the law of diminishing returns.
From what I've read on AVS, I don't have the funds, space or desire to go chasing single digits Does the 15" ported perform as well as multiple sealed above 15Hz? So you feel any pressurization effects at >=15Hz?

I don't listen at reference, Tom said I wouldn't notice any difference between 15V/V1500 and very slight with V1800. And V1800 in room extension is 17 vs 14 for V1500 (typo?).

This is a bit confusing because some of the most popular subs (Submersive, DSS) are sealed designs, never heard anyone say they lack anything.
