Center Stage

KICKER KS-Series Speakers let you play at concert-like volume, yet maintain the smoothness and subtlety to please even the most selective ear. Internally dampened polypropylene cones and durable rubber surrounds assist the woofers in creating precise midrange and bass, while high-quality silk-dome tweeters deliver natural, detailed highs.

Experience your music as a component system with separate tweeters, or as a high-end coaxial system. The woofers’ removable bullet-style phase plug is replaced with a special adapter, allowing the 25 millimeter, silk-dome tweeters to rotate and tilt. You get more system design options and superior off-axis performance. They work best with 15 to 125 watts of recommended power. See below for more details.

High power handling
Silk-dome tweeters for a smooth sound
Polypropylene woofer and tough rubber surrounds
Thin-mount design easily fits behind factory grilles

Great deal!

I can’t believe I snagged this deal. It’s a great price for so many spoons and they are the perfect size and thickness

Extremely poor quality. Too flexible!
Size: 1000 Teaspoons
Poor quality, flimsy, barely strong enough to stir my coffee. Not strong enough to use for eating even semi-solid food. Too much flex!

Strong and Durable, Great for Large Garbage Cans
Scent: Unscented, Size: 50 Count (Pack of 1)
I’ve got a large garbage can for a big family, and in the past, every other brand of bag I tried would always slip down when filling it, turning trash day into a messy nightmare. I finally decided to look for a heavy-duty, extra-large bag and found these 30-gallon Glad bags—and I’m glad I did. I even tested three different brands to see which one I liked best, and these came out on top by far. They’re rip-resistant, strong, and extra roomy, making them perfect for a busy household. Even if they’re a little more expensive than other bags, the durability and reliability make them totally worth the extra cost. No more wrestling with sagging trash bags!

Been Using These for Years
Scent: Unscented, Size: 50 Count (Pack of 1)
I have been using these Glad 30 gallon ForceFlex trash bags for years and they never disappoint. The black color looks clean, they are thick and strong, and the unscented option is perfect if you do not want artificial smells. They hold up well with heavy trash, resist leaks, and the drawstrings make them easy to tie and carry. Great quality and worth the price.
