For deeper, more resonant bass, start with your speakers’ low-frequency response and your room—not their power rating alone. If the main speakers cannot reproduce the bass you want, a powered subwoofer can extend the system’s low end. Placement and crossover settings then determine how well that extra bass fits the room and blends with the speakers.
How do I get deeper bass from my speakers?
Check how far down your main speakers are specified to play, then consider the room and listening position. Bookshelf and floorstanding speakers alike may benefit from a subwoofer if they do not reach low enough for your needs. A subwoofer is designed to reproduce the lowest bass frequencies and can fill in where the main speakers taper off.

Specifications are a starting point, not a promise of a particular result in your room. Bass can change noticeably with speaker and subwoofer position, nearby walls, and where you sit. Treat system setup as part of the decision rather than assuming a larger or more powerful speaker will automatically provide deeper or better bass.

A frequency-response specification gives a stated range of frequencies a speaker can reproduce, from its bass endpoint to its treble endpoint. The tolerance attached to the range matters: a claim with a stated ±3 dB tolerance is not directly interchangeable with a range that uses a different tolerance or test context.
#1 Best Overall
- 10" front-firing spun-copper IMG woofer
- All-digital amplifier with 300 watts peak power
- Volume low pass crossover and phase control
- Line level LFE RCA inputs for maximum receiver compatibility
- Dimensions 14 5" x 12 5" x 16 4"
For example, Klipsch illustrates the format with “21 Hz -29 kHz +/- 3 dB”: 21 Hz is the low-frequency endpoint and 29 kHz is the high-frequency endpoint. It is an example of how to read a specification, not a universal performance benchmark. When comparing products, compare the low-frequency figures only when their stated conditions and tolerances are sufficiently alike.
SVS lists the PC-2000 Pro’s frequency response as 17 Hz to 290 Hz ±3 dB in sealed mode. That is a manufacturer specification, not an independent measurement or a guarantee of the output you will get in your room. The retrieved product information does not state a publication year.
Power ratings are also easy to misread. Klipsch cautions that a higher peak or average power rating does not necessarily mean one speaker will be louder than another; sensitivity and other factors affect the result. Use power figures alongside compatibility and other relevant specifications, not as a stand-alone loudness ranking.

Do I need a subwoofer for deep bass?
You may want a powered subwoofer if your main speakers do not extend low enough, or if you want the system to reproduce the lowest bass without asking the main speakers to cover that range alone. Whether you need one depends on the speakers, your listening preferences, the room, and the system’s ability to connect and integrate a subwoofer.
When evaluating a subwoofer, compare its stated low-frequency extension and tolerance, whether it is sealed or ported, and the connection and placement requirements. Consider room size, listening distance, desired output, and whether bass needs to cover one seat or several. Do not treat a single specification as proof that one model will outperform another under different conditions.
The SVS PC-2000 Pro is one example of a subwoofer with a published sealed-mode response specification; that figure alone does not make it a universal choice. Match any candidate to your system and room, and check the current manufacturer page and model instructions for details.

Where should I place a subwoofer?
Klipsch says bass below approximately 80 Hz is generally perceived as non-directional, which can give a subwoofer more placement flexibility than full-range speakers. That does not mean position is unimportant: room boundaries and the listening position affect perceived bass, and the loudest spot is not necessarily the smoothest or best-sounding one.

- Place the subwoofer temporarily at your listening seat and connect it to the system.
- Play material with steady bass, then move around the room and listen for positions where the bass sounds balanced.
- Move the subwoofer to a promising position and listen from your usual seat. Try another location if the bass is uneven or sounds overly strong.
This method is based on Klipsch’s recommendation to put the subwoofer where you will sit and search the room for a position where it sounds good. It is a practical starting point, not a guarantee that one location will work in every room.
Account for corners and ports
A corner can make a subwoofer sound louder, but greater output does not automatically mean better sound. Experiment with placement instead of assuming the corner is ideal.

For a ported subwoofer, leave clearance around the port exit and avoid obstructing it with a nearby wall. Klipsch gives general guidance on port clearance for the subwoofers covered by its advice; the specific model’s manual should govern, because requirements can differ.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How should I position the main speakers?
Start with left and right speakers placed symmetrically and keep the path from each speaker to the listening area clear. If a speaker is rear-ported, Klipsch advises placing it some distance from the wall rather than blocking the port against it. Adjust positions by listening, since a room’s shape, furnishings, speakers, and other components all affect the result.
Klipsch’s guidance notes that there is no one-size-fits-all placement solution. Use symmetric placement as a starting point, then make measured changes and listen from the seat where you normally use the system.

How do I set the crossover between speakers and a subwoofer?
The crossover determines how bass is divided between the main speakers and the subwoofer. Choose settings in relation to the bass extension and output capability of the speakers in each channel, then adjust so the subwoofer blends with them rather than sounding detached or leaving an obvious gap.
Klipsch gives different crossover examples for large floorstanding speakers and smaller bookshelf or surround speakers. Those are examples, not universal settings: the appropriate choice depends on the actual speakers and system. Consult the speakers’ and receiver’s instructions, make an initial setting that reflects the speakers’ capabilities, and listen for a smooth handoff as you adjust.
Would a second subwoofer help?
A second subwoofer may help make bass more consistent across several listening positions, but the benefit depends on room size and placement. If you mainly listen from one seat, or if the room and current placement already produce satisfactory bass, adding another subwoofer is not automatically an improvement. Consider the seats you need to cover and the placement options available before deciding.
