Do you Think dual psa S1811 Will go as deep as the dual pb2000 becouse im happy whit the pb2000 there..?
I think that this question has been answered for you several times now. I know that I answered it on another thread. Yes!
The V1801's will definitely
go low enough, with enough SPL, in a small room like yours. There is an extensive article on "room gain" in Section VII of the Guide, linked in my signature. It will explain how room gain works in detail.
Briefly, small rooms amplify low-frequencies much more than large rooms do. But, they don't amplify mid-bass frequencies in the same way that they do low-frequencies. Mid-bass frequencies benefit from having a subwoofer near a wall (that is called boundary gain) and both small and large rooms will obtain that boundary gain about equally.
So, in a small room (such as your ~1400^3 room) you won't have any trouble at all in getting plenty of low-frequency sound and tactile sensations--low rumbling sounds and sensations--from a couple of good ported subs. That is because the room itself will amplify your low-frequencies with either PB2000's or with V1811's. But, if you want more mid-bass chest punch, then you will need subwoofers which are specifically stronger in those mid-bass frequencies. That is why you keep getting the same advice to buy V1811's, over-and-over on multiple threads.
I know that some of this is new to you, and that you are just trying to understand and to seek reassurance. But, the advice isn't going to change, and you can trust it. [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG] If you want more mid-bass kick (chest punch) while still having enough low-bass in your ~1400^3 room, then you should send your PB2000's back and buy dual V1811's. You will like the result!
Again, just for the record, I am a satisfied SVS owner, as are several others who have given you the same advice to exchange your SVS subs for PSA V1811's. We are all simply trying to be objective here about what will best help you to achieve your
goals and preferences. [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
