If I decided to get a single PB16 or PB4000 instead of duel PC/PB2000, could I use the PB400 or 16 as a sort of stand for the centre channel (GOLD C350) or would that be a good idea?
Just figured usually the centre below the tv would be a good spot for a single sub and also that COULD save me from having to purchase a centre speaker stand or a cabinet....
Any thoughts on this or is it a bad idea?
Also, given this space (1500 cubic feet) and PROBABLY would never upgrade to duels if the bigger sub-what decision on Duel 2000 vs single PB16 or PB4000 which are more and much more the. The price of the duels.
I think that one of the most common questions on this thread is: which model subwoofer to buy? The next most common question may be: should I buy one more powerful subwoofer or two less powerful ones? As a general rule, it is better to have two subwoofers to help even-out the frequency response in the room. It takes us a while to really start to understand what that means.
The room itself changes the sound that we hear from bass frequencies, causing some frequencies to sound louder and some to sound softer. If we can put two subwoofers in a room, usually on separate walls, we can help to get rid of some of those peaks and dips at random frequencies. If we do that, our bass sounds better. The fact that two subwoofers will average 6db louder than a single subwoofer is a bonus.
So, in general, although not always, it is better to have two subwoofers than just one. Now, which one?
I went back to look at some advice I gave you about 10 days ago, from several pages back, and I think it is still valid. I said:
"I couldn't tell from your previous posts that you were considering getting two PC4000's, instead of PC2000's. I think that the PC2000's will be enough for your room. Aren't you going to be able to try the PC2000's on approval? Once you have them in your room, you can decide for sure whether they are enough or not. If they are not, then
you can exchange them for the PC4000's."
I still think that this is the best way to go. Try the dual PC2000's (or PB2000's) and see whether they give you enough low-bass. If not, exchange them for the more expensive 4000's. Or, if you don't mind paying the higher cost of the dual PB4000's, then just start with them. I honestly can't tell from any of the information you have provided which subwoofers you should buy, although I do think that two PB16's will give you more low-bass SPL than you really need. You can't tell either, until you actually try something. But, whatever you try, I would advise you to have a plan to get two of them.
To answer your other question, it is perfectly fine to put your center channel on top of your subwoofer, although I would put something soft between them to protect their finishes. That could be either a PB2000, or a PB4000. You can turn the subwoofer sideways, or have it facing toward you. And, if you want to have a cylinder sub somewhere else to conserve floor space, you can have one PB2000 and one PC2000, or you can do the same thing with the 4000's or the 16's. Just plan to have two of the same model--the shape doesn't matter.
I hope this more detailed post helps, but I should repeat that no amount of speculation or advice will give you the answer you are looking for. You will just have to try a pair of subwoofers in your room, and move them around a bit, and let your AVR calibrate them, and then play with their volume, before you will know how much bass you are really looking for. That's what we have all had to do.
