|In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. |
Best way to find out...
Place your ULF drivers all together in an area of your choosing, then spend some real time with the SMS 1 dialing out the problem. Use the defeat function on the remote (I think its preset N° 6 by default) to decide how much destructive effect you are able to detect as a result of its intervention.
For now, you are using a bunch of 10" drivers (old mid-bass arrays) to produce sound below that of the 15" drivers in your mid-bass horns... It can be done, but it ain't natural and will certainly be calling on the SMS 1 to do more than if working with real ULF channels using drivers larger than those in the mid-bass horns. This means that when you evaluate the destructive effects while using the 10" drivers, you are likely witnessing a sort of worst case scenario.
