I think I'm finding the Samson s convert mini to the be the perfect tool for this mixing of equipment but it has a frequency response of 10 hz to 100khz. This is obviously good enough for my needs ( will be using it for my LR preouts to a crown amp ) but I'm just curious if there is another converter/bump box out that has an even wider frequency response
Here is the link to the s convert mini PDF

Ps: I already know the frequency response of the art box is 20hz-20khz so that doesn't make the cut in case I end up using my towers in full range mode for two channel music or film
