Durable materials and superior technology make the DSW Series a classic when it comes to subwoofers. Along with the heavy duty build quality, these elements insure smooth operation for years and years of big bass thrills. Inside, they’re smoothly tuned for better system blending and for bigger bass bang for your all-important buck, with exclusive technologies and patented engineering. The DSWPRO Series is the easy way to add excitement to your system. Three sizes to fit any room, and work with practically any electronics, while adding intense fun and dynamic realism to any system.

The Ultimate in Loud and Low

We all like easy choices. So, here’s an easy choice: Do you want big bass, bigger bass, or really really big bass? I know you’re thinking: It’s not that easy. I have a mid-sized room that I like to really fill with music, or I have a small theater setup that needs some low end excitement. Ok, fine. No problem. Because the DSWPRO Series of Polk Audio subwoofers makes your choice easy! With three excellent, efficient, high performance subwoofer models, the DSWPRO Series presents an easy choice. Choose the size that fits your space. You’ll be guaranteed the most extreme in deep bass thrills, whether you’re watching movies, playing games or listening to music.

Technology & Features

Internally Braced Enclosure

DSWPRO Series enclosures are designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies, and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances. Heavy duty MDF construction quality means better power handling, less wasted energy, and bigger, deep bass. Classy onxy-black finish is paintable, to match any decor.

Intelligent Amplifier Technology

High power, high current, and smart to boot. Polk intelligent amplifiers require less power to sound great, uses the power you give them more efficiently, and know when to stand down (especially at low volumes or in “Standby” mode). Even at extreme listening levels, it’s a wonder of digital high efficiency, bullet-proof reliability and minimal heat generation. Smart sensing circuitry knows when to turn itself on and off. Superior compression circuitry limits distortion at extreme volume levels. Compact size keeps enclosures small.

Feed Forward Distortion Suppression Technology

We wanted to design a subwoofer that avoids distortion and damage, but that preserves as much low end dynamism and as much output capacity as possible. We wanted the biggest bass, with the least distortion. This has always been difficult, because it’s a fact of loudspeaker life that if you play it too loud, it will distort. To change that fact, we programmed our digital subwoofer processors with a mathematical model that knows in advance how the woofer’s acoustic system will respond to the output signal from the amplifier. The digital processor monitors the amplifier for signal combinations that would cause distortion or damage, and alters only that part of the signal required to maintain safe operation. It does this instantly, before the signal ever gets to the woofer driver itself, so there’s no correction time delay, and no need for limiting or compression. It’s called feed forward distortion suppression technology, and only Polk has it. It allows us to set our performance limits much higher than normal, much closer to the actual (theoretical) maximum output of the subwoofer, with no risk of excessive distortion or damage.

Polk Room Optimizer™ (PRO)

The most important question when it comes to subwoofers is, where do you put it; how do you compensate for room size, room setup, placement position? With "one size fits all" subs, you’ll be forever shifting positions to try to find the bass sweet spot. With the DSWPRO Series, you can choose one of four preset "room optimizers" from the remote controller, and Polk’s exclusive PRO technology programs in the optimal bass and blending setting for your room.

Klippel Optimized Woofer Structure

Our state-of-the-art Klippel distortion analyzer reveals flaws in the motor structure and movement path before they become performance-robbing problems. This is especially important in fast moving, heavy duty, hard-working loudspeakers like subwoofers. By optimizing the woofer’s motor structure, voice coil alignment and suspension for smooth, unimpeded movement over a broad spectrum of the lower frequencies ensures the best, most efficient performance even at extreme listening levels. Plenty of movement is the key to seriously deep Polk bass.

Dynamic Balance® Materials

Using advanced laser interferometry, Polk engineers can actually see how materials react before they build a speaker with them. By finding and eliminating surface resonances and distortion areas, Polk can design unique driver materials, speaker geometry and enclosure construction techniques that actually produce cleaner, clearer sound. This is our patented Dynamic Balance process. DSWPRO Series subwoofers feature Dynamic Balance materials and construction elements that help them perform effortlessly in high stress, big bass situations when you need them most.

Composite Polypropylene Woofer

DSWPRO Series uses lightweight, super-stiff composite polypropylene cones for greater efficiency and more cone control. Dynamic Balance materials tuning ensures low resonance and minimum distortion even at high volume levels, for maximum bass for your buck. Durable rubber surrounds provide superior damping, free range of motion, and don’t rot like cheap foam surrounds. You’ll thrill to years and years of reliable subwoofer performance.

Modular Firing Configuration Options

DSWPRO subwoofers can be arranged with their feet forward or down, for standard downward-firing position or innovative front-firing mode (you can snap on the grille and it looks smart). This kind of flexibility means you can place the subwoofer just about anywhere, even inside audio furniture or a rack system, and experience superior deep bass excitement.

Slot-Loaded Port Design

Traditional circular ports can be limited in their performance enhancements; they only have so much surface area to work with. The unique slot-loaded port design of the DSWPRO Series adds significantly more port surface area, for deeper, smoother bass response even in a smaller cabinet size. Special tuning eliminates unwanted chuffing and air turbulence at the mouth of the slot-loaded port, for distortion-free bass.

Remote Control

Never have to leave your seat while you adjust your subwoofer to its optimum performance level. Watch for feedback from the blue status LED (which can be switched off). Four-way phase selection allows for easy blending with your main speakers, and your remote unit gives you full control of the Polk Room Optimizer (PRO). This control is not just remote, it’s total.

Multiple Professional Connection Options

LFE, line level inputs and outputs and 5-way binding posts for speaker level inputs allows easy connection to any system.

Night Mode

Your DSWPRO Series subwoofer has the colossal power to wake the house and all your neighbors. But, we’re reasonable. So we provide a "Night Mode" setting, temporarily lowering the sub’s intensity. A quick and easy toggle from the remote control, and everyone’s happy.

Perfect System Blending

DSWPRO Series subwoofers blend perfectly with systems composed of other Polk loudspeakers. Build the system of your dreams, and then add the perfectly blended, deep musical low end that takes it over the top!

Adjustable Stabilizer Feet

Use adjustable rubber feet for hard surface flooring, and adjustable carpet spikes for carpet. Both options give you more placement flexibility, and a totally dependable, more efficiently stable setup. No energy is wasted on your subwoofer crawling across the floor.
