Comparing Performance and Sound Quality: Polk DSW PRO 440 vs PRO 550 vs PRO 660

I’ve had the opportunity to test out the Polk DSW PRO 440, DSW PRO 550, and DSW PRO 660 subwoofers, and I’d like to share my thoughts on their performance and sound quality.

ModelRMS OutputPeak OutputWoofer Size
PRO 440300W1200W8″
PRO 550400W1600W10″
PRO 660500W2000W12″

Polk DSW PRO 440: It’s the smallest of the three, featuring 300 watts of RMS and 1200 watts of peak power. The 8-inch woofer delivers tight bass but may not be ideal for larger rooms or those looking for earth-shaking sound. However, small to medium-sized rooms can take advantage of their compact size and impressive performance.

Polk DSW PRO 550: This mid-sized subwoofer offers 400 watts of RMS and 1600 watts of peak power with a 10-inch woofer. It strikes a perfect balance in terms of performance and size.
The added power compared to the 440 results in a more commanding bass response, making it a great fit for medium-sized rooms or home theaters.

Polk DSW PRO 660: The largest of the three, it produces 500 watts of RMS and 2000 watts of peak power, boasting a 12-inch woofer. The 660 pushes deep, powerful bass that can be felt as well as heard. Ideal for larger rooms and high-impact home theaters, this subwoofer doesn’t shy away from creating an immersive experience.

When it comes to sound quality, all three subwoofers are equipped with Polk’s signature sound technology. They succeed in delivering clear, distortion-free bass that’s accurate and tuneful. Here’s what stands out for each model:

  • Polk DSW PRO 440 – Tight bass, suitable for smaller spaces and music enthusiasts
  • Polk DSW PRO 550 – Balanced and impactful bass, excellent for medium-sized rooms and home theaters
  • Polk DSW PRO 660 – Deep, powerful bass with high impact, perfect for larger rooms and high-end home theaters

It’s important to consider the room size and your specific needs when choosing a subwoofer. If you value a more compact subwoofer for small to medium rooms and prefer listening to music, the PRO 440 may be the best choice for you.
On the other hand, for those looking for a solid middle ground with incredible bass response, the PRO 550 will likely fit the bill. The PRO 660 surely takes the cake if you’re after the ultimate home theater experience or have a large space to fill.

Since performance can be influenced by room layout and acoustics, be prepared to do a bit of tweaking to find the optimal placement for your new Polk subwoofer. Remember, it’s all about finding the right balance to suit your listening preferences and enhance your overall experience.

Size and Design Differences: Polk DSW PRO 440 vs PRO 550 vs PRO 660

When comparing the Polk DSW PRO 440, DSW PRO 550, and DSW PRO 660, it’s essential to examine their size and design differences. Each subwoofer comes with its own set of features and specifications that make it unique, catering to various needs and preferences.

DSW PRO 44014.4″14.4″15.3″35 lbs
DSW PRO 55016.5″16.5″18″47 lbs
DSW PRO 66019.5″19.5″20.5″69 lbs

The Polk DSW PRO 440 is the smallest of the three models. It measures 14.4 x 14.4 x 15.3 inches (H x W x D) and weighs 35 lbs. This compact subwoofer is perfect for those with limited space or seeking a more subtle presence. Its black vinyl finish and cloth grille provide a classic, unobtrusive look that fits seamlessly into most home theater setups.

Stepping up in size, the DSW PRO 550 measures 16.5 x 16.5 x 18 inches (H x W x D) and weighs 47 lbs. With a slightly larger build than its 440 counterparts, this intermediate model accommodates those looking for a subwoofer with more heft and output. Like the 440, it also flaunts a black vinyl finish and cloth grille.

Lastly, the DSW PRO 660 is the biggest and most powerful model among the three. It measures 19.5 x 19.5 x 20.5 inches (H x W x D) and tips the scales at 69 lbs. This subwoofer boasts impressive performance for those craving substantial bass and room-shaking impact. The design remains consistent with the 440 and 550 models, featuring the same finish and grille.

Installation and Setup Process

When it comes to the Polk DSW PRO 440, DSW PRO 550, and DSW PRO 660, I can gladly attest that the installation and setup process is relatively straightforward for all three subwoofers, with just a few differences to note.

DSW PRO 440 and DSW PRO 550 share a similar installation process – both come with an easy-to-follow manual and I found they’re designed to seamlessly integrate into any home theater or audio system:

  • Connect the subwoofer cable to your receiver’s subwoofer output
  • Connect the other end of the cable to the subwoofer’s LFE input
  • Plug the subwoofer into a wall outlet and turn it on

I found the DSW PRO 660 installation process to be slightly different due to its wireless connectivity features. Here are the steps:

  1. Connect the wireless transmitter to your receiver’s subwoofer output
  2. Plug the transmitter’s power adapter into a wall outlet
  3. Connect the wireless receiver to the subwoofer’s LFE input
  4. Plug the subwoofer into a wall outlet and turn it on
  5. Press the wireless pairing buttons on the transmitter and the subwoofer

Another aspect that varies between the models is placement. While all three benefit from being positioned close to a wall, I discovered that the DSW PRO 440 can be installed horizontally or vertically, thanks to its Compact Vertical Extension (CVE) design.

For both the DSW PRO 550 and DSW PRO 660, their size and design call for significant floor space; so, planning the subwoofer’s position in the room is essential in obtaining optimal sound effects.

It’s worth experimenting with different room placements until the desired bass performance is reached. However, I strongly suggest you avoid these common positioning mistakes:

  • Do not place the subwoofer in a room corner, as it may accentuate distortion and lead to unevenness in sound
  • Avoid obstructing the subwoofer by placing it behind the furniture

Price and Value for Money

When it comes to deciding between the Polk DSW PRO 440, DSW PRO 550, and DSW PRO 660, one can’t ignore the price and value for money aspect. I’ve used all three models, and in this section, I’ll share my views on their pricing and whether they offer a good bang for your buck.

Starting with the DSW PRO 440, it’s the most affordable option among the three. The lower price point doesn’t compromise its performance though, making it a great entry-level choice for those who want a solid subwoofer without spending too much.
Some features contributing to its value include its compact size and the option to switch between downward-firing and front-firing modes.

The DSW PRO 550 sits in the middle of the price range, offering a good balance between price and performance. It has some notable upgrades compared to the 440 models, such as its more powerful amplifier and larger driver, providing a deeper bass response.
It also includes the Polk Room Optimizer (PRO) feature, which allows for easy customization of the subwoofer settings based on room placement.

Finally, the DSW PRO 660 is the most expensive and most feature-packed option among the three. Its powerful performance, larger driver, and highest wattage amplifier all contribute to the significant increase in price.
Additionally, it comes with a remote control, and it boasts the same Polk Room Optimizer (PRO) feature as the 550 models.

In terms of value for money, let’s break it down:

  • For those on a budget, the DSW PRO 440 offers an excellent entry-level option without sacrificing performance.
  • If you’re willing to invest a bit more, the DSW PRO 550 hits the sweet spot between price and performance, with its more powerful amplifier, larger driver, and room optimization feature.
  • For those looking for top-tier performance and all the bells and whistles, the DSW PRO 660 is worth the investment, providing the most powerful and feature-rich option.

It’s important to consider your specific needs and budget constraints before making a decision on which model to choose. Each one offers its advantages, and hopefully, this breakdown helps you make an informed decision.
