Klipsch Synergy Sub-10 review


Klipsch Synergy Sub-10

Amply endowed 10-inch subwoofer; 200-watt amplifier (FTC rated); versatile connectivity.

The sonic match with its companion SLX speakers is far from seamless.

Klipsch's Synergy Sub-10 is powerful and musical, and that's not something you always find in midpriced subwoofers.

Klipsch Synergy Series SLX/SUB-10 System Reviewed


Positional the SLXs for optimal performance was easy. Watching movies the bass texture was "rich, deep, tight and quick." While the music was not quite as good as the movies, it did sound "very good through the SLXs." The Klipsch Synergy Series...

Klipsch Synergy Sub-10


The Klipsch Synergy Sub-10 is one of many great audio components that this company manufactures. As a down-firing subwoofer, it offers much more room rumble than most other subwoofers. If you're looking for a powered subwoofer that mercilessly thumps...

The Klipsch Synergy Sub-10 delivers incredible power as a down-firing subwoofer

The down-firing speaker tends to shake loose the electrical connections

The Klipsch Synergy Sub-10 provides a great physical and audible listening experience.

The best Thing ever


We bought one of these ten years ago to go with the quintet III speakers and a Yamaha amp. 10 years later its built in amp finally blew. I took it out of the cabinet, put it in an extra 10 inch subwoofer car audio box, went to a thrift store, picked up...

Lasts 10+ years

Klipsch Synergy Sub-10 420W 10" Subwoofer Black


Should have purchased 2. I use the Klipsch KLF20's for my fronts, they are coming up on 15 years of service with only one tweeter replacement.

Owned and operated this unit for close to two years without a problem. The unit is powered by an Onkyo 7.2 Surround system and set to 180 degrees out of phase with gain at half. Still kicking for going in and out of standby for 24x7x365 day period....

Great sound

All the reviews saying theirs died were probably due to playin the thing full throttle! I've had mine for years without an issue. Decided to purchase another and hook up both

Quick Shipping


As of today, still on sale on Newegg at a very good price. I would highly recommend to others, even at $169, you will not find another subwoofer on the market to compare for the money.

Speaker arrived in 2 business days after order placement. Subwoofer arrived in good condition, hooked it up, sounds awesome. This subwoofer replaces an identical unit that died after several years. I spent the extra on sale $20 for the extended 3 year...

Didn't last


The subwoofer was loud. It sounded great, I loved it

Died within 23 months. Newegg lists a 2 year warranty on it, so I think I might be able to get some compensation under warranty, but I was disappointed. I really only used this subwoofer very little. The gain was always turned to AT MOST halfway,...

Died with only moderate use


Sounded good

I bought 2 last summer. They were never driven hard. By the time winter came they both had died

Consumer review by: D (



Can't believe Klipsch allowed this model to be marketed. It lends some credence to Klipsch critics' complaints about the production quality of its products.

Bought to complement a set of two Klipsch B-20s (front L&F), four S-10s (front presence and surround), and two C-20s at center along with an older Polk Audio sub, all powered by a Yamaha V667. The Sub-10 replaced the PA Sub and completely rounded out...

After only 17 months of very light usage, the Sub -10 went the way of so many other Sub 10s (Google Klipsch Sub 10 problems and you will find a large number owners who have had the same problem). a call to Klipsch tech service suggested replacing the...

Product Specifications

A masterpiece of sound and design, the Synergy Series Sub-10 shakes things up with its rock-solid performances. Its extraordinary power adds a dose of "reality" to movie explosions and other special effects, as well as reveals commonly elusive lower musical tones. The Sub-10 reaches deeper and hits harder thanks to a 10-inch, down-firing driver coupled to a highly efficient BASH Class D amplifier that creates 200 watts of continuous power and 420 watts of dynamic power. Because of its ample enclosure size and large, rear-firing port with flared ends, the Sub-10 produces increased bass response with low distortion. The subwoofer's built-in, steep-slope (24dB/octave) low-pass crossover is continuously adjustable from 40 to 120Hz. A phase control facilitates acoustical integration of the subwoofer with the other speakers in the system. An "auto power" feature enables the subwoofer to turn itself on and off (standby) automatically, based on the presence or absence of an audio signal. A blue/red dual color LED display on the front of the subwoofer indicates whether the unit is on or in standby mode. In addition to delivering a bass impact that's beyond restraint, the Sub-10 features a new industrial design that is refined and aggressive. Available in a black finish with titanium accents, this extraordinary subwoofer matches the entire Synergy Series lineup in both style and performance. With its charged presence and room-rocking abilities, the Sub-10 delivers an adrenaline rush of sound that will impress your friends and provide years of high-quality audio entertainment.
