Do smaller subs like the Kali WS6.2 or SVS Micro 3000 offer tighter bass compared to 12 inch subs because of the smaller woofer? Or does woofer size not matter?

As you noted in your post, you need to decide if sealed or ported is your preference. Seems like resources are not limited, so perhaps in the room of that size you could go for 4 sealed subs and count on room gain in the lower end. Generally ported would give you a better lower extension up/close to port tuning point so could get SPL at lower price.Hi all experts JTR sub
@sweetchaos
I am confused about what subwoofer works best based on my room size and my listening interest
i would like to get your opinions and advice on what model to choose
JTR 4000 OR JTR RS2
My Interest is 95% movies & 5% music
room size 21 * 15.4 * 8.8 = almost 2846 cu.ft
I will be using 4 subs
my system 9.4.4
any advice or recommendation I would be grateful
There is no such thing as "overwhelm" in a tuned system. A lot of unused headroom, sure.That could help with distortion, but overall, having 8 18" drivers in such a medium room might really overwhelm it regardless of al
And why would you tune your system to 2x or even more of what you need? There is charity if u want to give away money, no?There is no such thing as "overwhelm" in a tuned system. A lot of unused headroom, sure.
Tuning a system with subs—I mean measuring response and establishing correct levels, gain, bandwidth, crossover and EQ. How many subs a person needs and what size they should be are then a question of SPL vs. frequency (which can be approximately calculated fairly easily).tune your system
Agreed, but why would you want to just argue semantics vs provide the advice to OP? Is that helpful or useful in your view?Tuning a system with subs—I mean measuring response and establishing correct levels, gain, bandwidth, crossover and EQ.

I was specifically responding to you and your use of the word "overwhelm". Subwoofers do no such thing unless played untuned.

Well many thanks, but there is much more to how subs work. Perhaps the whole storyline is warranted to make sure none go astray.I think it is helpful to understand how subs work.
In your advice, you caution against too many subs because they will "overwhelm" the room. Since that will not happen, the OP has the much simpler task of calculating the SPL they want to achieve and can reduce the number of subs as needed.
Here's how I think about it (after spending a lot of time reading, it is a pretty simple problem in the end, once you know what does/doesn't matter):Well many thanks, but there is much more to how subs work. Perhaps the whole storyline is warranted to make sure none go astray.
So just to simplify - OP needs less subs for its room (which we know so little of except the cft).?
4 subs makes sense if you are following the Welti/Harman approach to smoothing FR across many positions.Hi all experts JTR sub

I think anyone who would not want the above and would find it ridiculously oversized or overpriced for the room at stake might be right. Not really sure what is the whole point of the above?Here's how I think about it (after spending a lot of time reading, it is a pretty simple problem in the end, once you know what does/doesn't matter):

How much SPL do you need? JTR 4000ULF in @sweetchaos' sheet shows 122dB SPL at 20Hz (CTA-2010-A, 2m peak). Easy estimate for sub SPL: 2x the number of subs, +3dB (this number is arguably higher, but it's a good, conservative estimate). So:
Reduce by 3dB if you want RMS values. Reduce by 3dB per additional doubling of distance to the listening position.
- 1 JTR 4000ULF: 122dB SPL
- 2: 125dB SPL
- 4: 128dB SPL
Cost is about $20k USD before tax and shipping. If you can handle that and have the room, and like the way those giants look, I don't see why not. Otherwise, you can spend less and get smaller subs, if you like.
If the OP can afford the subs and likes how they look, and wants to play "make the walls shake", it's fine. I don't think we should arbitrate how another person will spend their money. If the OP is making the mistaken assumption that small subs cannot produce sufficient bass or that very high SPLs are absolutely necessary, then we can help by explaining. But he has to ask for that first.I think anyone who would not want the above and would find it ridiculously oversized or overpriced for the room at stake might be right.

Above is just a simple SPL calculation, does not take into account the room modes and possibility to create such SPL at some frequencies that might interfere with the room correction and really get in the way of properly EQing the system.
If someone wants the power above, they should understand in much detail how it would work in their room. Smaller systems are inherently safer as they will not “overpower” the room or the budget.
While I continue to disagree or all your points and pretty shallow explanations of those, I don't think that this thread will benefit from our continuing discussion. So as the final point, you might want to consider what "overpowering" means in plain words as I could not find a common definition of what it means in "acoustical sense" as you have put it."Overpowering" the room has no acoustical sense, while "overpowering" the budget is something for the OP to decide. Too much bass never killed anyone, earthquakes aside.
is it dedicated HT or living room? If not dedicated, there will be some resonance frequencies in the lower end that you will need to deal with.
See the attached papers or read Toole's book.I enjoy reading your discussion of my question I am very interested that the number of subwoofers be Four
Just to be clear, this is not important for well-designed subs.sealed or ported

Do you know how you are going to measure and adjust these subs? I assume an AVR.
Go for either model. You will have more bass than you'll know what to do with.by Anthem AVM90

The footprint (W*D) of RS2 is literally half of 4000ULF. Which means that you can buy 4 RS2's for the footprint of 2 4000ULFs, assuming they are stood upright.JTR RS2 4799$
