Klipsch SW-450 Powered Subwoofer Reviewed


The SW-450 is one of Klipsch's more affordable offerings. On movies and games, the overall sound was very good. "It never seemed to run out of power and offered great punch, weight and extension." It is built well and "looks as good as anything in its...

The Klipsch SW-450 performs wonderfully with movies and games, with excellent punch, weight, and extension that often belied its small size

The SW-450 needs more refinement on musical tracks, especially acoustic, classical, and jazz material, where its big but sometimes uncontrolled sound imposes a bit too much on the material ; The SW-450 lacks a high-pass crossover output, which could...

The SW-450 offers the classic Klipsch value proposition - great build quality, dynamic, aggressive performance, affordable price. It's not the most refined subwoofer sonically but, at the same time, it kills on movie and gaming material, offers some...

Klipsch SW-450


A substantial-sounding subwoofer that's more than capable, but some rivals can handle complexity better

Substantial and weighty sound; understated looks

Can lose its way with more complex basslines

Klipsch Synergy B20/SW450


More notable for its vibrancy than its flaws, but the Klipsch is an acquired taste

Intriguing driver arrangement; positional flexibility; full-strength, energetic sound

Sub plods as the speakers sprint; tweeters lack refinement

The most "Bang" for your "Bump..... >:3 see what I did there?!


HITS...HARD, Rich deep BASS That fills the room, beautiful design box, and at a crazy low price. I owned 1 for 3 years now, and once I saw this for more than 50% off it was a no brainer. Having one was amazing so having food means it has to be better....

That my neighbors in the lower and upper apartment have given me noise complains, not really sure if that's a con lol

Thundering Astroids!


When on sale, this is a great buy. Larger than what I thought it was going to be. Has left/right RCA patch sockets, but you really just need one cable for left on SW and receiver. The shipping box was the actual box used to house the SW. It arrived...

Great bass! Rocks the whole room and seats! Great construction / looks

Blue LED bright in dark room ; Shipped in its own box; no double boxing ; Box arrived damaged (but SW is functional w/o visible damage) ; Box had small piece of glass embedded ; Auto on/off doesn't always work

Great component


Part of an overall system upgrade. Joins 4 Klipsch B-20 for front & rear plus a Klipsch C-20 center. This is a small room so didn't go wild with larger or higher end gear. Sounds great to my ears

None I can think of

Quite an upgrade


Very happy with this purchase. Will be using another vendors wireless kit to be able to reposition in my 5.1 arrangement

Solid response, bass is clear, wide and powerful ; Light years better than an old Polk sub I replaced ; Nice aesthetic, cabinet fits in well and is not too onerous in size ; Connectors and adjustments are all standard, adjusted the cross over after two...

None other than this sub does not support the connector required for the klipsch specialized wireless kit. Be forewarned that despite the klipsch website showing compatibility it is not

Product Specifications

The SW-450 subwoofer uncovers what you've been missing in your music, movies and video games - clean, chest-thumping bass. It's an ideal companion for many of the front, center and surround speakers, whether you're looking to achieve a 5.1 system or a 5.1 on the Richter scale. Great sound begins with a great bottom end. The SW-450 subwoofer delivers the two lowest octaves of the ten humans can hear, intensifying your listening and viewing experiences. The SW-450 fills any room with big, clear bass, thanks to its powerful 10-inch driver and Class D amplifier. But if you really want to experience what this hard-hitter can do, be sure to place it in the corner of your room. In general, placing a subwoofer along the middle of the wall, or out in the room will decrease its output. In addition to its unparalleled performance, the SW-450 offers unmatched flexibility. A low pass crossover and variable phase control lets you effectively blend the subwoofer's low-frequency tones with other Klipsch speakers as well as establish a level of bass that's just right for your room. The SW-450 subwoofer is truly the way to go if you want to hear and feel your stereo or home theater entertainment.
