Excerpt: If you are looking for a solid complement to your previously purchased subwoofer, the Klipsch Quintet 5.0 speaker system is good choice. The Klipsch Quintet doesn't feature a matching subwoofer, unlike many of the home theater systems we reviewed, but it does give you the option to mix and match subwoofers and build your own home theater system. If you don't currently own a subwoofer, the Klipsch Quintet will not produce prominent bass.
Pros: These speakers are highly efficient and have a solid frequency response range.
Cons: This speaker system does not come with a subwoofer. You need to match these speakers with a dedicated subwoofer if you want full frequency response.
