Would you notice a difference with a sub having 106db SPL at 20hz vs. A sub with 96db spl at 20hz at low listening levels in a small room?

Depends how loud you listen to 20hz at I suppose....is 96dB your max listening level at your seat? What is the acceptable distortion level at this mark? How far from the sub will you be? Does the 96/106dB sub do that at 1m? 2m? or?

 

[shadyJ]

At low listening levels, probably not with normal content like most movies and music. With a pure test tone, you might notice the difference.

It is not possible to answer that question. The shape of the subs curve is crucial. The real question to ask to determine this, is what is the output at 40 hz compared to 20 Hz with the same voltage drive.

In other words say that the 96 db sub at 20 Hz is also at 96 db or close at 40 Hz with the same voltage drive signal.

Now say that the 106 db sub at 20 Hz is 120 db at 40 Hz with the same drive signal. then the 106 db sub will give you more output in your room.

So you have asked a question that can not be answered without more data.

thanks a lot for the input, i am comparing the svs pb 2000 non pro with the svs sb2000pro.

this is the data for the pb2000

this is for the sb2000 (i cant find data for the pro version, it should probably be slightly better)

listening position is around 1.5 meter

listening level is around 70db i would say

When in doubt, buck up and buy the next size up.
I vote PB2000 Pro.
You will cry once. Then be happy for quite a while.

Until you learn about 15 and 18" Subs.

With the above figures, the PB2000 is definitely the obvious winner. It is more efficient at 20 Hz and has less distortion than the sealed sub.

The sealed sub would be good if you didn't have the space to install the bigger ported driver cabinet.

FWIW, I recently redid one of my systems with a pair of KEF R3 Metas and a Rythmik F12SE (similar to a SB2000). I’m in a huge room and listen at high levels. The saving grace is that like you, I sit quite close. The Rythmik isn’t disappointing, with either music or movies.

In my case, I didn’t want to deal with more large / heavy subs, and was prepared to buy multiples. Just didn’t need to.

 

[Goldhasmter916]

thanks a lot for the replies.

i definitely see that the ported performs better, i just dont know if i would noticed the difference when sitting so close (1.5m) and listening at rather low/moderate listening levels in a very small room (4x3m). if i would barely notice the difference i would rather go with the smaller sub to save space.


@ryanosaur I appreciate that mindset

SVS does have a pretty good return policy, right?

 

[lovinthehd]

Is the room you're going to use it in a forever room? Listening levels won't change with a move? I'm more of the just get the better sub now and be done with it mindset....

 

[Goldhasmter916]

i just moved in, so yes i think this will be the room for quite a long time.
I could get a pretty good deal on a used sb2000pro. I am considering buying the sb2000pro (which I could probably resell without a los) and then ordering a new pb2000 and return it if I decide to keep the sb.

thanks for all your Replies!

The ported is the winner. The ported design will have the lower distortion and is clearly the winner. You will hear a difference. The sealed sub will actually have a native F3 somewhere north of 40 Hz, and then there is 12 db. per octave applied below F3, this is inefficient and adds stress and distortion. The only reason to buy a sealed sub is if you don't have the room for a ported one.

Pb for the win

 

[Bobby Bass]

I believe the non-pro doesn’t have the app so would recommend the Pro of any version. unless you don’t mind having to make adjustments by hand once in place. My pair of Pros are tucked away in the front corners and it would be a struggle to get to the back of them to make adjustments. SVS is excellent about returns so would definitely take advantage of trying what you think is best and then deciding if you want to keep or change once you’ve had time listening in your room.

 

[Goldhasmter916]

Thanks a lot for the replies. I ordered a used Sb2000PRo for 860, immediately got fear of missing out low end power, selled it for 1000 and got, after some research, a klipsch RP 1400SW Ported sub on sale for 1000 (which usually goes for 1300 here). It will arrive tomorow and i couldnt be happier!

Thanks for your time!

 

[William Lemmerhirt]

Just curious. What were the deciding factors that lead to buying the Klipsch?

 

[Goldhasmter916]

couple of reasons:

A seemingly very knowledgeable helpful person at audioholics explained peaks in movie effects (which I mainly care about along gaming effects) especially on the low end, are Reaching over 100db if your average listening levels is 70db. The sb2000pro might struggle there. He also explained how ported subs tend to provide a stronger tactile response, what is also important to me. I realized I really want to have the peace of mind i get all the performance within my room even if the sub is way bigger.


The RP 1400SW Is design wise a scaled down version of the somewhat more potent but architectural similar RP 1600SW which has comparable specs to the SVS PB 3000 but measures even better at very low frequencies.

this gives me hope that the RP 1400SW which has similar specs to the SVS PB 2000Pro will perform at least at that level. The SVS PB2000PRO however costs 1300 here, whereas I could get the RP 1400 on sale for 1000. which is the same price as the PB1000PRO which should be significant weaker.
The normal pb2000 would have been an option but I like the klipsch better design wise and the pb2000 is a nine year old design.

besides That the more subjective review on the new klipsch line are very positive.

I can also sell the SB2000Pro for roughly 150 bucks more than buying price.

I know there are a lot of assumptions but from everything I have gathered it is very likely that the RP 1400SW performs better than the SB2000PRO for the same price.

 

[lovinthehd]

I'm not sure how a ported sub would have a stronger tactile response outside of it's basic capabilities of generally being more capable of more efficient output at the lowest frequencies....a sealed sub can do as well in terms of tactile response but will depend on room, placement and eq and amp power.....then there are actual tactile transducers, like the one in my seat (but the large sealed sub right behind my seat helps, too). Still, probably wouldn't go for a Klipsch again (I have an RW12d).

 

[shadyJ]

The RP-1400SW is probably a pretty good sub. It won't have the deep bass of the 1600SW but I would bet its mid-bass is closer than most people would think. I am sure you will be happy with that unit.
