Meyer Sound X-400C Compact Cinema Subwoofer

With a clean, accurate sound all the way down to 20 Hz, the X-400C shares the sonic characteristics of the X-800C subwoofer, at half the size

Product Description

Part of the EXP cinema series, the Meyer Sound X-400C Compact Cinema Subwoofer boosts low-frequency headroom in cinema applications and other fixed installations. The linear, self-powered X-400C offers similar sonic characteristics as the X-800C subwoofer — low-frequencies down to 20 Hz, clean, punchy transients, and excellent phase coherence — though in a more compact cabinet that can be installed singly or as multiple units.

The X-400C is comprised of a single 18-inch low-frequency, long-excursion cone driver housed in an optimally tuned, vented cabinet and powered by a single-channel amplifier. Onboard processing includes driver protection circuitry, low-pass filtering, and correction filters for flat phase and frequency responses.

The IntelligentAC power supply affords automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.

The X-400C integrates seamlessly with other EXP cinema loudspeakers, including the Acheron screen channel loudspeakers and HMS surround loudspeakers.

The X-400C cabinet is constructed of premium birch plywood and coated with a low-gloss, black-textured finish. The cabinet includes attachment points for an optional grille frame with black cloth.


  • High peak power output with excellent transient reproduction

  • Extremely low distortion forexceptional low-frequency clarity
  • Flat amplitude and phase responses for tonal accuracy
  • Integrates with Acheron Studio and Acheron Designer screen channel loudspeakers
  • Integrates with HMS-5, HMS-10, and HMS-12 surround loudspeakers

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.

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.
