Choosing home theater speakers & subwoofers starts with one practical question: do you need a dedicated powered subwoofer, or a pair of passive bookshelf speakers? The Acoustic Audio PSW-12 and Polk Audio M10 are designed for different parts of a system, so the right pick depends more on the missing component in your setup than on price alone.
Quick verdict
Choose the Acoustic Audio PSW-12 when the gap in your system is a home theater powered subwoofer with Stereo L/R RCA inputs. Choose the Polk Audio M10 when you need a pair of compact passive bookshelf speakers for stereo or rear surround use, especially if built-in wall-mounting slots are useful. The PSW-12 is $149.89 more than the M10 pair, making the component role the key decision.

Where each product wins
Acoustic Audio PSW-12

The PSW-12 wins when your system specifically calls for a powered subwoofer rather than additional bookshelf speakers. Its Stereo L/R RCA inputs give it a clearly defined connection option, and its wired design suits a cabled home theater arrangement.
Polk Audio M10
The M10 wins when you need a speaker pair for a stereo setup or rear surround channels. Its built-in keyhole slots are a practical advantage for wall mounting without buying extra brackets, while the $49.99 listed price keeps the initial component cost lower than the PSW-12.
Product notes
Acoustic Audio PSW-12 Subwoofer
The Acoustic Audio PSW-12 is the more direct fit when your system needs the product type named in its title: a home theater powered subwoofer. Its Stereo L/R RCA audio inputs provide a concrete connection option, while wired connectivity keeps the choice focused on a cabled arrangement. The listed black color is also straightforward for a typical home theater setup. The limitation is scope: this is a subwoofer, not a pair of bookshelf speakers, so it does not fill the same role as the Polk M10 pair. The PSW-12 also has a $199.88 listed price, which makes it the more substantial component purchase here. Choose it when the dedicated subwoofer role is the part your system still needs.
Polk Audio M10 Bookshelf Speakers Pair

The Polk Audio M10 makes sense when you need two compact passive bookshelf speakers rather than a subwoofer. The title and description identify a pair, and built-in keyhole slots support wall mounting; the description also names stereo systems and rear surround sound channels as possible uses. Its wired connectivity suits a conventional speaker-wire arrangement. The key limitation is the passive design: an amplifier or receiver is required. It is also listed as used, with light cosmetic wear described. Those details matter more than the low price if your system lacks amplification or you want a powered component. Choose the M10 for a pair-based stereo or surround build where an amplifier or receiver is already part of the setup.
Final choice by use case
- Need a dedicated powered subwoofer: Choose the Acoustic Audio PSW-12, with its subwoofer role and Stereo L/R RCA inputs.
- Need a pair of bookshelf speakers: Choose the Polk Audio M10 pair for stereo or rear surround applications.
- Want wall-mounting support: The Polk M10 has built-in keyhole slots.
- Already have an amplifier or receiver: The passive Polk M10 can fit that setup, provided its required amplification is covered.
- Want a wired subwoofer connection: The Acoustic Audio model offers wired connectivity and Stereo L/R RCA inputs.
The bottom line is simple: the PSW-12 adds a powered subwoofer, while the M10 adds a passive speaker pair. Match the purchase to that specific gap, and the choice becomes much clearer.
