The JBL CSS-1S/T is a pair of compact passive loudspeakers voiced to deliver enhanced speech intelligibility and foreground/background sound reinforcement for indoor environments such as retail shops, cafés, and classrooms.

Capable of up to 60W long-term power handling, the CSS-1S/T incorporates a 5.25" woofer and a 0.75" dome tweeter to produce a maximum SPL of 106 dB and a frequency range of 85 Hz to 18 kHz (-10 dB). The speaker configuration yields a 120 by 120° dispersion pattern for consistent coverage.

The lightweight and sturdy polypropylene enclosure can be placed on a shelf or mounted to a wall with the supplied ball-type bracket. An integrated 10W multi-tap transformer—configurable via a rear-panel tap selector—allows operation in 70/100V systems or 8-ohm low-impedance setups.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.

Great
Size: Medium, Color: (001) Black / Black / Pitch Gray
The best pair of work / workout / casual socks I've bought in long time! They're no show on all my sneakers, incredibly comfortable and they never move.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
