I also have the 1450 concreat bunker..:-)
I talked whit Tom at PSA and he also Recomended seald subbs for my room becouse its so smal and he suggested S3000i/S3010 or maybe S1800. Its a shame that i cant test them in my room and return them if they dont fit my needs becouse i have to ship from England Live in europe.
What did he ended up whit..?
This is a complicated subject which I'm not sure that everyone understands the same way. Sealed S3010's can produce even more mid-bass SPL than the V1811's will. But, the V1811's will already be roughly twice as loud in the mid-bass as your PB2000's. So, in my opinion, the V1811's will give you plenty
of mid-bass chest punch.
But, if you go with sealed subs, you will be giving up some of the low-bass tactile sensations that you are used to. Yes, you would have sufficient low-bass SPL
with large sealed subs, but you would be giving up some of the low-bass rumble that you feel now with your PB2000's. That low-bass tactile response (TR) is not just the product of SPL. Ported subwoofers feel
different down low, because the ports themselves move air, and that adds to the tactile sensation.
Since you are already happy with the low-frequency SPL and tactile sensations, I wouldn't try to fix something that isn't broken. I would stay with ported subs, which you already know that you like. What I would do, though, is to find ported subs which will give you more chest punch, and that is where the V1811's come in. They will give you what you are used to down low (and a little more of it) and they will give you a lot
more of the chest punch you are looking for. That's the Win-Win I was talking about.
MKtheater can answer your question for himself if/when he comes back to the thread. But, at one time, he had several large sealed subs in his 1400^3 concrete bunker. And, he was able to get tremendous output levels and low-frequency extension. But, he missed having the tactile sensations that ported subs provided. As you can see from his signature, he moved to large ported subs. If I remember correctly, he did that specifically to get the low-frequency tactile sensations that we are talking about.
A lot of people just look at subwoofers' performance in terms of SPL. But, for those of us who enjoy the tactile sensations of bass, the SPL that subs produce is not the only thing that is important. Ported subs produce much more tangible tactile sensations down low than sealed subs do. And, PSA ported subs deliberately concentrate more SPL in the mid-bass range where you will feel chest punch. For your specific situation, I believe that V1811's will be the perfect solution.
I also wish you could audition some subwoofers, but honestly the fact that you can't is why I am being so careful. I am recommending that you stay with the low-bass that you already like, and just add subwoofers that will give you more mid-bass.
Since you are still hesitant, however, I will make one other suggestion that will cost less and present less risk. Why don't you buy a Behringer B1200D subwoofer? It is a ported sub, with a tuning point slightly above 50Hz. That makes it extremely powerful in the mid-bass range. And, that mid-bass range is where it was designed to be used.
You could position it right behind your listening chair, and it would supply you with a lot
of additional chest punch. That way, you could add the chest punch you want while still keeping your PB2000's for the full-range and low-bass. A number of people on the forum have tried these little subs with excellent results, and they aren't expensive. A number of places carry them on the Internet. Here's one:
