Barefoot Sound MicroSub45 Dual 8" Active Studio Subwoofer - Single

Dual 500 watt 8" subwoofer featuring Barefoot Sound’s innovative Dual-Force technology
MFR# MicroSub45-Single

Product Description

Custom designed to complement the best-selling MicroMain45, the Barefoot Sound MicroSub45 delivers hyper-accurate low-end using two 8-inch drivers with Barefoot’s innovative Dual-Force technology. The MS45 uses the same signal path, amplifier and driver technologies as the class-leading MiniMain12 in a more compact and affordable package.


Two 8-inch aluminum cone drivers with Dual-Force technology deliver tight, punchy low-end down to 25 Hz when used with the MicroMain45s. Dual-Force technology uses an innovative force-cancelling design to eliminate vibrations within the speaker cabinet, resulting in distortion-free sound at any volume.


The MicroSub45 is designed to be used in stereo pairs with MicroMain45 reference monitors. Each subwoofer is equipped with a mono analog balanced crossover at 80 Hz to extend the low-frequency response of the system. And with 500 W of class-leading power in each cabinet, the MicroSub45 also increases the headroom of your system.

MicroMain45 monitors and MicroSub45 subwoofers are also available as a package — the stereo MicroStack45 system. Although the MicroSub45 is custom-tuned to compliment the MicroMain45, it can also be used to extend the low frequency response of any speaker system.

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.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
