Subwoofer Pros Studio Sub2 18C 18" Subwoofer

Active 700-watt 18-inch subwoofer with bass extension down to 16 Hz, 4-position low-pass switch, and two summing inputs


Product Description

The Subwoofer Pros Studio Sub2-18C is a universal sub used for bass extension of any studio monitor. It is sealed and self-powered, offering bass extension to 16 Hz. It has a compact cabinet using an 18” high excursion sub driver with an easy to use control set. It has built in Left/Right XLR summing inputs and a low pass filter at 4 different frequencies of 95 Hz, 80 Hz, 60 Hz, and 40 Hz. The different low pass frequencies make it adaptable to various size “main” speakers.

The Studio Sub2-18C is different from other subs because it specializes in output below 95 Hz, the range which meter bridge monitors are generally not good at. The sealed cabinet with a linear response sonically outperforms subs that make use of ports, transmission lines, passive radiators or other “boost” technology. These boost methods create the sonic impression of bass up around 75-85 Hz but actually suffer a severe roll off after the boost. These boost methods make it more difficult to get proper translation between studio and outside world.

The Studio Sub2-18C’s larger size allows for accurate, increased SPL for larger spaces. The Studio Sub2-18C’s design is ideal for applications where multiple subs are used to achieve evenly distributed low end in large rooms by locating them on different walls. This multiple sub approach at lower SPL can significantly outperform a single higher SPL sub that generates fewer but higher intensity room modes or nulls. The modest price, universal fit, and flexible nature of the Studio Sub2-18C makes it an ideal way to start with one or two and grow your sub system over time.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
