Sub woofer match

Rataxes

hello
I would like to add a sub woofer to my speakers set , however , I do not know which one is matching the best , and I hope that someone could recommend me one. (POLK only )
The set includes front speakers - TSi 400 , and a CS10 center in between them , in addition there's a pair of TSi100 in the back .
Receiver is Pioneer VSX - 521 k

Thank you for your help !

20hz

looks like your speaker goes down to 44 hertz the psw 125 goes down to 32 to 80 hertz so it should fill the void nicely , you just gotta be sure you like the way the cabinet looks and fits in your location , as with any subwoofer I recomend buying a bigger more powerfull unit because you can always turn it down but if it cant make the amount of bass you like there is no turning up a small sub once its maxed .
I have been building subs for 15 years and learned that lesson the hard way

I wouldn't take a manufacturers specs as gospel, your in room response will vary greatly as everyones rooms are different.
