Audio professionals in need of a subwoofer that's designed to complement the SRX900 Series full-range sound reinforcement systems will be impressed with the JBL SRX928S, a dual 18" powered subwoofer well suited for rental companies, touring artists, DJs, and installations. The integrated DSP and amplification offer a true plug-and-play experience while providing consistency and optimum performance anywhere in the world.

The two 18" Differential Drive woofers are powered by the built-in Class-D amplifier and provide a frequency response of 31 to 100 Hz at 140 peak SPL. The SRX928S incorporates a large central low-frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A full-featured software package provides users control of the system on various platforms including Windows, Mac, and iOS for iPad.

  • Built-in, passively cooled Class D amplification with a universal power supply

Performance
The 2279-1 18-inch woofers deliver transparent, linear bass response down to 31 Hz. This driver uses dual 3" voice coils and leverages JBL's patented Differential Drive technology to deliver maximum sensitivity and power handling in a light, compact design.

Compatibility
SRX900 Series subwoofers are acoustically compatible with all SRX900 full-range speakers and support 60 Hz and 80 Hz operating modes. SRX900 line arrays can be ground stacked with SRX900 subwoofers using the optional base plate accessories.

Controlled Coverage
SRX900 subwoofers can be used in omnidirectional or cardioid configurations simply by selecting the appropriate speaker preset and cabinet orientation. The preset can be accessed directly from the rear panel LCD or via software.

Powered Solution
The fully integrated built-in amplifier and DSP are based on proven JBL technologies and explicitly packaged to fit the needs of the SRX900 Series. The DSP includes everything needed to optimize a system, including 24 user-adjustable filters, 2000ms of delay, and advanced features like array size compensation and FIR-based throw distance correction filters.

Versatile and Scalable
The SRX900 Series offers a complete system solution, including speakers, subwoofers, accessories, and software that support a variety of configurations and simplify storage, transport, and rigging. Because systems are scalable, it's easy to start with a small system and add components over time. All SRX900 products have been designed to work seamlessly together with other JBL tour sound products, with common voicing targets and phase characteristics that ensure systems combine coherently.

Good quality, smooth feel
I got these briefs so recently that have washed just one pair so far. First off, these are very comfortable, the material is soft & bordering silky, good quality sewing. Wash well and minimal if any shrinkage. They do come a bit wrinkled from the dryer but hey, these are underwear and will go on smoothly. If it were a t-shirt, I would look sloppy. I feel the sizing is accurate. No rolling and these don't announce themselves under clothing. Planning on getting more of these boxers and replacing my old panties.

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.
