Hi all,

I have the original CBM-170s and just purchased a new Denon AVR-X2400H receiver. That - and Tidal have renewed my interest in listening to HiFi stereo music. However, my subwoofer is a pretty inexpensive Polk (PSW10?). I am wondering how much better music will sound with a more expensive musical subwoofer? (I really don't want to break the bank, so my budget is less than $500 though) Would it be worth it? If yes, what subwoofer would go well with my CBM-170s for HiFi music?

Mike
