At each location, you will need to take a total of five measurements. Mark the location and record the microphone height for each location so that you can measure again after optimization. Vary the height as well as the horizontal location.

One of these should be the center of the listening area, while the other three should be spread over the listening area. You will need to measure in four different locations. This is just a precaution - when you run the levels check in REW, you can increase this if needed. On the Outputs tab, name the output channels Left, Right, Sub1 and Sub2.Įnable the 100 Hz highpass filter crossover on the Left and Right channels.Įnable the 100 Hz lowpass filter crossover on both subwoofer channels.

The app note Tuning multiple subwoofers with miniDSP makes some suggestions, which we suggest adapting for dual subs. There are no hard and fast rules about where to place subs when doing a multi-sub system. Note: we recommend that you thoroughly familiarize yourself with measurements using REW and with using the SHD plugin before starting this advanced application. Dual-sub stereo system with the miniDSP SHD Power Figure 1 is a typical system configuration using the SHD Power.įigure 1.

Processors with more outputs such as the C-DSP Series and DDRC-88A can be used with some adjustments to parameters (and in that case can optimize for more than two subwoofers). The smaller DDRC-24 and 2x4 HD can also be used. To process the filters produced by MSO, we deployed a miniDSP SHD Power integrated processor/amplifier in our test system, but any member of the SHD Series can be used instead. As an alternative, a miniDSP UMIK-X can be used for faster measurement in multiple locations. We recommend a miniDSP UMIK-1 or UMIK-2 together with Room EQ Wizard (REW) for this purpose. MSO needs measurements taken around the listening area as input to its calculations. In addition, MSO will optimize the crossover frequency between the subs and the speakers.

We will use the freeware software Multi-Sub Optimizer (MSO) to optimize two subwoofers and two speakers to reduce spatial variation. Three (or more) subwoofers are usually recommended for a multi-sub system, but it is still possible to gain an improvement with two. Well-applied use of multiple subwoofers reduces spatial variation.

For example, with a single subwoofer, if the level at 40 Hz in one listening seat is 10 dB different to the level in the next, the difference between the two seats will be 10 dB regardless of how much EQ is applied. While EQ such as REW auto-EQ or Dirac Live can smooth response at any given location, this will not correct for spatial variation. Multiple subwoofers are used to improve evenness of bass response across the listening area. For questions or issues specifically related to MSO, please refer to the AVS Forum MSO discussion thread. miniDSP is not able to directly provide support for this software. Please note that MSO is third-party software. $(document).This app note demonstrates the use of Multi-Sub Optimizer (MSO) to integrate two subwoofers with two speakers in a stereo system.
