Ideal for theatres, performance venues, auditoriums, and houses of worship, the Bose Professional ShowMatch SMS118 is a subwoofer module for arrays designed to integrate with DeltaQ array loudspeakers. Offering low-frequency extension down to 29 Hz, this powerful sub sports an 18" neodymium driver with a max power handling of 750W RMS.
With a specifically designed Baltic-birch enclosure and integrated rigging, this subwoofer is designed to quickly integrate with ShowMatch full-range array modules and can also be used for ground-stack deployments. With the convenient 4-point quick pin rigging system, the SMS118 supports up to 18 subwoofer modules without difficulty.

DeltaQ Technology
DeltaQ is the next-generation array design that allows Q (directivity) to vary with each module in the array for more consistent coverage over a wide frequency range, reduced array weight and cost, and outstanding vocal clarity. Arrays can cover large vertical angles with fewer boxes.

The 18" transducer sports a 4.5" voice coil and provides excellent performance, being essentially the same transducer as in the Bose Professional RMS218.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
