With a focus on fidelity and a sleek, award-winning, ultralow-profile design, the hunter green GSB8 In-Ground Subwoofer from JBL is the perfect complement to the GSF full-range landscape speakers, providing a powerful 8" polypropylene driver that can be mounted underground but still provide potent subwoofer performance down to 35 Hz.

Grab handles make it quick and simple to install and anchor points are included for securing the cabinet to blocks or anchors.

Good basic tanktop
Color: White, Size: Small
The material feels really nice and soft to the touch. It’s great as a basic tank top for everyday wear, especially during hot weather. 🌤️ The fit is flattering and shapes the body well without feeling too tight. Simple, comfortable, and easy to match with anything!

Very flattering
Color: Royal Blue, Size: Small
I ordered four of these tops, two white, a beautiful royal blue, and the great green one . There are so many things to like about this top but they didn’t work for my needs. The fabric is a nice weight, it is form fitting but not clingy, soft and comfortable, I was looking for tops that would not expose my bra straps. The style is cut in at the shoulder which will show your straps. If that’s not an issue for you then you will love this top. Can be worn by itself, under a suit jacket or blouse. The colors are bright and flattering, perfect for spring and summer.

Nice Fit - Casual or Dressy Casual
Color: Black, Size: Large
The tank top is comfortable, true to size and form fitting with great length (tank runs about 3 inches past my waist). I like the look and fit so much I bought the same tank in several different colors. The tank looks great with my wide leg jeans and below the knee bubble skirt. The tank is versatile and can be worn for leisure or dressy casual creating a polished look, i.e. wear with a blazer or smart casual skirt. I watch for a discounted price as some colors may be offered at a lower price.

High neck tank top
Color: White, Size: Medium
Very see through. I wear beige bras, the bra looked very dark through the shirts. The fit across the chest runs small in size medium and large but the large came in a long length. I’m 5’1”, the large almost came down to my thighs. I returned the medium and large. I actually like the shirt, I couldn’t get the right fit for me.
