1 of those would be better then 2 1000?\n\nDepends on the target imo. Iirc below about 25 hz the Pb2k pro has considerably more output and definitely extends deeper. In a smallish room like that I’d expect the pb2k to outperform two pb1k in deep bass. \nHowever, having two will definitely have an advantage in possibly smoothing out the response. This is not a given though, and placement should explored to make sure the advantage is realized. Also, Ime most people upgrade from the 1000 series after too long anyway. It’s a good entry level subwoofer but it leaves a lot on the table. From SVS, I believe the 2000 series is the best value for most a average sized rooms and listening habits.
