The SVS SB17-Ultra R|Evolution ($2,499) represents SVS's latest flagship technology, featuring a massive 17-inch driver powered by dual mono-block amplifiers delivering 2,800W RMS. Its sophisticated 295MHz DSP processor offers advanced room correction capabilities that can optimize bass response with greater precision than the PB-2000 Pro. The sealed design and dual voice coil configuration provide exceptionally accurate bass reproduction, particularly noticeable with complex musical passages and demanding movie soundtracks where subtle details matter.
While the SB17-Ultra R|Evolution delivers superior performance across the board, its premium price point places it in a different category altogether. The additional investment brings tangible benefits for larger rooms and critical listening scenarios - deeper bass extension to 15Hz, significantly more headroom, and more sophisticated room integration. However, these improvements may not justify the higher cost for users with medium-sized rooms or moderate listening levels. The SB17-Ultra makes the most sense for dedicated home theater spaces, critical listening rooms, or situations where maximum performance is the primary consideration regardless of budget.

The $749 Klipsch RP-1000SW takes a more straightforward approach with its 10-inch Cerametallic driver and 300W RMS amplifier, focusing on delivering musical performance in a more compact package. Its front-firing port design offers greater placement flexibility, making it particularly suitable for smaller rooms or situations where the subwoofer needs to be positioned near walls.

The SVS 3000 Micro ($799) takes an entirely different approach to subwoofer design, focusing on delivering impressive bass from an ultra-compact footprint that's barely a cubic foot in size. Its innovative dual opposing 8-inch driver design and powerful 800-watt amplifier allow it to produce surprisingly deep and controlled bass down to 23Hz, despite its diminutive dimensions. While it can't match the PB-2000 Pro's ultimate low-end extension and output capability, the 3000 Micro excels in situations where space is at a premium, offering remarkable flexibility in placement options including behind furniture or even wall-mounting.
Released more recently than the PB-2000 Pro, the 3000 Micro showcases some of SVS's latest engineering achievements, particularly in terms of cabinet vibration control and driver optimization. Its sealed design and sophisticated DSP tuning result in exceptionally tight and musical bass response, making it particularly well-suited for music listening and smaller home theater setups.

The SVS SB-2000 Pro ($999) takes a different approach with its sealed design, offering a more compact solution that excels in music reproduction and smaller spaces. Where its ported sibling prioritizes maximum output and deeper extension, the SB-2000 Pro delivers faster, more precise bass response that some listeners prefer for music. The sealed cabinet design results in a significantly smaller footprint - roughly 14 inches in each dimension compared to the PB-2000 Pro's larger size - making it much easier to integrate into living spaces while still maintaining impressive output capabilities down to 19Hz.
Despite its higher price tag, the SB-2000 Pro justifies its premium for those seeking a more versatile subwoofer that excels in both music and movie playback. Its tighter, more controlled bass response and smaller form factor make it particularly appealing for mixed-use rooms or when space is at a premium. While it won't match the PB-2000 Pro's maximum output or lowest frequency extension, the SB-2000 Pro's ability to deliver articulate, musical bass while maintaining enough impact for home theater use makes it a compelling option for those who prioritize accuracy and placement flexibility over maximum output.

The SVS SB-1000 Pro ($499) takes a different approach with its sealed design, offering exceptionally tight and accurate bass in a remarkably compact package. At nearly half the size of the PB-2000 Pro, its 13.5-inch cubic form factor makes it significantly easier to integrate into living spaces while still delivering impressive performance down to 20Hz. The sealed cabinet design provides exceptional control and precision, particularly beneficial for music listening, while the 325W RMS amplifier offers plenty of power for small to medium-sized rooms under 2,000 cubic feet.
For those prioritizing space efficiency or primarily focusing on music, the SB-1000 Pro presents a compelling value proposition at its lower price point. While it can't match the PB-2000 Pro's maximum output or depth for heavy home theater use, it offers similar technology including the smartphone app control and advanced DSP features.

The SVS PB-1000 Pro ($709) offers remarkably similar performance to its bigger sibling, delivering impressive bass extension down to 17Hz and sharing the same sophisticated app control system. Despite its more modest 325-watt RMS amplifier, it handles most home theater content with authority and maintains excellent control during complex musical passages. Its more compact cabinet dimensions and lighter weight make it easier to position in typical living rooms, while still providing the refined bass response SVS is known for.
For most users with rooms under 2500 cubic feet, the PB-1000 Pro represents the better value, offering nearly 90% of the PB-2000 Pro's performance at a slightly lower price point. While it can't quite match its larger sibling's ultimate output capability in larger spaces or at reference volumes, the difference in real-world listening situations is subtle enough that many users would be hard-pressed to justify the extra cost and size unless they specifically need the additional headroom. For music listening and typical home theater use, its performance-to-size ratio makes it an incredibly compelling option.

The $284 Klipsch Reference R-120SW stands out as a compelling value proposition, offering robust performance at a significantly lower price point. Its 12-inch copper-spun IMG woofer and 200-watt RMS amplifier deliver punchy, articulate bass that works particularly well in small to medium-sized rooms. While it doesn't reach the extreme low frequencies of the PB-2000 Pro, bottoming out at 29Hz instead of 16Hz, most listeners will find its bass extension more than adequate for both music and movie playback. The simpler control scheme and more compact cabinet size also make it an attractive option for those who prefer a straightforward setup or have space constraints.
Where the Klipsch R-120SW really shines is in delivering impressive performance for everyday listening without breaking the bank. While it may not match the PB-2000 Pro's ability to pressurize larger rooms or reproduce the deepest movie effects, it provides clean, musical bass that enhances both casual viewing and critical listening. For those working with a modest budget or smaller space, the R-120SW represents an excellent balance of performance and value, offering roughly 70% of the SVS's capability at less than half the price. Its efficient design and reliable performance make it a smart choice for listeners who want to enhance their system's low end without venturing into premium subwoofer territory.

The PB17-Ultra R|Evolution ($2,999) represents SVS's latest flagship achievement, pushing the boundaries of what's possible in home subwoofer performance. Its massive 17-inch driver with dual 8-inch voice coils, powered by a 2,800-watt amplifier, delivers nearly four times the output capability of the PB-2000 Pro. This translates to effortless reproduction of even the most demanding bass passages, with extension down to a room-pressurizing 12Hz. The advanced DSP and auto-room correction features provide unprecedented control over the listening experience, making it easier to achieve optimal performance in challenging spaces.
While the PB17-Ultra commands a premium price, it justifies the investment for specific scenarios - particularly in larger rooms over 3,000 cubic feet or for enthusiasts seeking ultimate performance. The ability to tune the subwoofer using multiple port configurations offers flexibility that the PB-2000 Pro can't match, and its massive headroom ensures clean, distortion-free bass even at reference levels. However, this level of capability isn't necessary for many users, and the physical size and weight (165 pounds) make it more challenging to integrate into typical living spaces.

The $664.99 SB-1000 Pro takes a more refined approach with its sealed design and compact form factor. While it doesn't match the raw output capabilities of the PB-2000 Pro, its 325-watt RMS amplifier and sealed cabinet design deliver remarkably precise bass that some listeners may actually prefer, especially for music. The smaller footprint - requiring less than half the space - makes it significantly more flexible for placement in real-world living spaces, while still reaching down to an impressive 20Hz.
For smaller rooms under 2,000 cubic feet or where space is at a premium, the SB-1000 Pro represents an exceptional value proposition. Its tighter, more controlled bass response excels with music reproduction, offering articulate low frequencies that maintain their composure even at higher volumes. While it may not deliver the same room-pressurizing impact for movie special effects, it still provides more than enough output for most home theater applications in moderately sized rooms. The $328 savings over the PB-2000 Pro makes it a compelling choice for those who prioritize space efficiency and musical accuracy over maximum output capability.

The Klipsch Flexus SUB 100 ($239) takes a different approach, prioritizing convenience and accessibility with its compact form factor and wireless connectivity features. At just 13 inches cube and weighing only 20.7 pounds, it's significantly easier to place in smaller rooms or apartments. The wireless connection capability with Flexus series soundbars eliminates cable management concerns, while its 80-watt RMS amplifier and 10-inch driver provide respectable performance for casual listening and everyday TV viewing.
While it can't match the deep bass extension or output capabilities of the SVS, the Klipsch offers impressive value at its price point. The sealed cabinet design helps deliver tight, musical bass that works well in smaller spaces where too much low-end might be problematic. For users with more modest needs or those primarily using a soundbar-based system, the Klipsch provides a balanced combination of performance, convenience, and affordability. It's particularly appealing for those who want to enhance their audio experience without the complexity and space requirements of a larger subwoofer.

The Klipsch WA-3 Wireless Kit ($206) takes a fundamentally different approach to bass integration, focusing solely on solving subwoofer placement challenges rather than delivering bass performance itself. This compact wireless solution eliminates the need for long cable runs by transmitting audio signals up to 50 feet using the 2.4GHz band, with automatic channel selection to avoid interference. For owners of compatible Klipsch C-Series subwoofers, it offers a cost-effective way to optimize subwoofer placement without compromising audio quality or requiring room modifications for cable routing. The ability to connect up to three subwoofers with a single transmitter adds flexibility for more complex setups.
While the WA-3 can't match the PB-2000 Pro's advanced features or bass performance, it serves a specific and valuable purpose for existing Klipsch subwoofer owners. At less than a quarter of the PB-2000 Pro's price, the Klipsch WA-3 provides a simple, plug-and-play solution that maintains signal quality while adding placement flexibility. However, its limited compatibility with only Klipsch C-Series subwoofers means it's not a universal solution, and ultimate performance still depends entirely on the capabilities of the connected subwoofer. For those primarily concerned with placement flexibility rather than upgrading their bass performance, it represents a practical and cost-effective option.
