An unbalanced miniDSP or a Reckhorn B-2 would do the trick. The miniDSP would have many more options, but is a bit more expensive. I have both and would get the miniDSP 10:1 if you like to tinker.
+1. I have done this before with accurate results.What's the input impedance on the amplifier? (And is the amp just for the sub?)
Could easily put a capacitor on the input.
This is interesting. I'm also looking for getting a minidsp, but this could be a short term solution. looking forward for more details+1. I have done this before with accurate results.
If a 1st-order filter is all you need, this is by far the simplest and cheapest solution.
Thank you.That is correct IF (notice the big "if") your amp impedance is about 8-10Kohm. Since we don't know, you will need the resistor.
How about you tell us what amplifier you are using, and maybe we can figure out a simpler filter for you.
