Product Description

Amazon.com Product Description

This JBL 400-watt, 12-inch powered subwoofer reproduces sound with incredible power, delivering the punch that puts the "cinema" in home-cinema system. The custom-designed MDF enclosure provides unparalleled spaciousness and definition, while the PolyPlas polymer-coated cellulose fiber cone woofer features traditional JBL engineering--the same technologies used in JBL's professional audio equipment found in stadiums, music halls, and movie theaters around the world. Meanwhile, a high-temperature, oversized, state-of-the-art fiberglass voice coil and HeatScape motor structure let this subwoofer effortlessly and endlessly play all types of movies and music.

The woofer is built on a cast-aluminum frame, which reduces distortion and increases power-handling capability. A low-diffraction IsoPower baffle directs the sound into the room, reducing the distortion often caused by cabinet vibration. In addition, the lock-mitered, computer-designed enclosure requires no bracing, while the FreeFlow flared port increases bass response without adding unwanted port noise. And to top it off, the high-performance, high-efficiency, high-output amplifier produces an incredible, room-filling 400 watts of bass power--enough to satisfy even the most demanding bass enthusiasts. And to ensure the cleanest possible signal, all Studio series loudspeakers are equipped with all-metal, five-way, gold-plated binding post speaker terminals.

Specifications include a 22 to 150 Hz frequency response and a continuously variable crossover from 50 to 150 Hz. The sub measures 16.19 by 17.19 by 18 inches (W x H x D) and is backed by a five-year warranty on parts and labor.

5.0 out of 5 stars A great addition to my AV system, March 24, 2002

By A Customer

This review is from: JBL S120P II 12" 400-Watt Front-Firing Powered Subwoofer (Black Maple) (Electronics)

Have been using this excellent product for less than a month, but I think it's a great choice. I connected the S120PII with a Transparent Cable Link 200 cable after hearing and reading about complaints concerning subwoofer buzz and hum. As a side note, I would recommend getting a good cable. I say this after upgrading the Monster cables to my front speaker pair with something called Synergistic Research. The improvement was immediate; an extended audio image and larger bass notes (without subwoofer).

Anyways, my receiver only sends frequencies under 100Hz to the sub; so when I first listen to the sub, I momentarily thought the sub was defective. The cable and sub combination puts out tight and very clean sound.

After playing with the level control, I realized the low frequencies were there. I didn't have it very loud at this point and at lower volumes, frequencies under 100Hz seem to contribute more to audio imaging than to a louder bass presence. I later did the wall shaking drill; with 400 watts, this sub does a nice job of it.

The directionality of the bass notes from the sub will depend on the frequencies sent to it. According to tech literature, somewhere between 80 to 100Hz the location of the LFE speaker will become slightly evident at higher volume levels. At 100Hz, I did not detect any obvious directionality.

This is a great subwoofer. Invest in good wire; you will not be disappointed.

This review is from: JBL S120P II 12" 400-Watt Front-Firing Powered Subwoofer (Black Maple) (Electronics)

I did extensive research and listening and this unit if worth every bit the original asking price; at the Amazon price, this subwoofer is a steal. Its in the ballpark of Velodyne and B&W (see Sound and Vision magazines Review) at less cost be watt. I've had mine for 4 months and the bass is tight and thudering without the boomyness you find on lesser-powered subs. A friend has a 700 watt Velodyne and the 400 watt JBL delivers the bass just as impressively. Unless you have the need (and finances) for 1,000+ watts of power, you can get BIG bass for an unheard of price from this well-made and solid JBL sub.

I had always stayed away from subwoffers due to often exaggerated muddy lows. This one delivers clean and very contollable lows. Very easy to set-up with a modern receiver. Often goes om sale at amazon. The technology is a little older but the best of older designs. You can get better, smaller, lighter for a whole lot more money with only a subtle improvement.
