Dynaudio BM14S - Single – No Longer Available

300 watt active subwoofer with one 12" woofer
MFR# 995011011

Product Description

The Dynaudio BM 14S subwoofer is perfectly aligned for operation with the BM and M series monitors.  For larger multichannel setups with, e.g. five M1.5's, multiple BM 14S's will be a preferred choice.

The BM 14S is designed to take care of the most challenging requests and it will compliment larger stereo and multichannel setups in even the most demanding studios.

The BM 14S has been designed as a closed cabinet type subwoofer.  This type of cabinet design gives you significant control and enhancement of the general performance as the closed cabinet creates an internal pressure.  This adds considerably to the amount of accurately reproduced low frequency signals.  When audio reproduction is more accurate, it will add to the sense of reality, and the BM 14S ensures exactly that.

The BM 14S is very suitable for the following production environments:

  • Post production
  • Music recording and mixing
  • Film editing
  • DVD authoring and mastering
  • Multichannel production (audio or audio for pictures)
  • Broadcast
  • Edit suites

With an auto on/off function, energy usage shuts off after minutes of no input signal, thereby saving energy when the subwoofer is idle.  As soon as an input is detected, the auto sensing circuit enables the subwoofer to come back to life.

A satellite filter feature is provided by the BM 14S, enabling adjustment of low-pass corner frequencies from 50 to 150Hz of the monitor source signal.  The subwoofer will thus take care of the lower and power consuming frequencies, and thereby adding to the performance and clarity of the monitors in the system.  This is due to the high-pass filtering feature that the BM 14S comes with.  If the need arises to daisy-chain more subwoofers to the same system, the low level LFE output gives you exactly that choice.

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.
