So I have a psw10 as my sole sub, it was fine, nice and punchy bass, i recently upgraded my speaker wires all around to 12 gauge copper, i used to run the speaker through the speaker inputs, i got a speaker plug for it instead and no longer do that. I bought a Klipsch rp450c center and 2 rp280 f towers, i moved my 10 year old infinity towers to the back surrounds. Now evrything is great, if i completely turn the sub off as it struggles so bad to handle what it used to easily. I have the same Denon reciever i have had for about 8 years. It was an upgrade needed to be able to have a 4k signal. I welcome any suggestions, the 2 towers have 2 8 inch woofers each so they put out a decent bass, but i miss my little punchy psw10 coming through with the rest of the bang, explosion or whatever.

    Those Klipsch tower speakers are 98dB efficient, meaning they can get really loud with much less power than most speakers. Also, the -3dB level goes down to 32 Hz meaning they put out excellent bass by themselves. The -3dB level of the PSW10 is only 40 Hz meaning it's not capable of outputting bass to keep up with your new speakers. The PSW10 was a budget product. It performed well for what it was but it's pretty limited.

    Time to look for a new subwoofer! :)

    Klipsch makes better performing subwoofers than Polk plus your new speakers are Klipsch. You may want to get a Klipsch subwoofer or look into some other brand like SVS. You'll need to spend a few hundred bucks to get something that'll match better with your main speakers.

    Another option, which I would not recommend pursuing, is running the speakers as "small" and directing all the bass to the PSW10 for home theater sounds.

    You also need to run the AVR calibration program any time you change anything.

    Time for an SVS. Even the cheapest SVS will blow your mind if you liked the Polk.

    If you are mostly a home theater user get a ported design

    As mentioned you must re-calibrate especially if you are coming from bookshelf or stand speakers
    ...and an SVS would definitely be an upgrade
