My main speakers are Martin Logan Motion 40 with smaller Motion series all around. I currently own an SB-2000, which is underwelmimg in my current 960 cubic foot room. I originally bought the sealed sub because of footprint and musicality, but think that ported will serve better for my listening habits.
My budget is $2000 max, and was thinking about the PC-4000, wife likes the form factor. Then I was thinking that maybe for the same price, that 2 PC-2000 might be a better choice, but also thought that since a 2000 series sub that doesn't perform well in a smaller room that I would be better off with a single 4000 series sub.(possibly add a second in the future)
Do you think that 2-PC-2000's will be enough for that room.
I did email SVS and Jack was leaning toward the 2000's for dealing with room mode issues.
Thank you for your advise,
Two subs are generally better at dealing with room modes, than a single sub, assuming that they can be strategically positioned. So, I agree with Jack about that. But, in my opinion, that is only part of the issue when trying to select what sub or subs to buy. If you buy two PC2000's now, you should be able to have a better frequency response now, again assuming good subwoofer placement.
If you buy a single PC4000 now, you may give up some of the benefit now of an improved frequency response, but you will gain the benefit now of having lower extension and more <20Hz SPL and TR (tactile response). That can be important too in a 3000^3 room.
If you buy a PC4000 now, and add another one later, you will have the benefit later of both improved frequency response, and lower extension and more <20Hz SPL and TR.
There are some elements of instant gratification in both of the first two scenarios, with the trade-off between improved frequency response with dual subs, and lower extension and more individual horsepower from a single sub. The third scenario has the added element of better long-term planning, in my opinion. I think that it makes sense to select subs on the basis of their overall capabilities, and to then add multiples as needs and opportunities dictate.
For that reason, I would normally advise someone to select the sub with the lowest extension he may want (that is primarily dictated by the tuning point with ported subs) and that he can reasonably afford. And then, to add another identical sub when he can. That would be my advice in this case. I would go with the PC4000, if I were you. I think that once you hear more of the <20Hz frequencies, you will be hooked.
