![]() I do not know your willingness or capability to DIY. Difficulties involve connecting the parts together, providing circuit power and enclosing in a robust stable chassis. The parts to make a simple fixed active filter set are relatively inexpensive. At best you might implement a one or two pole passive dialed in for your specific system. you're looking for (half) a crossover.įirst you will never be able to approach a -24 dB/Octave filter passively without huge sensitivities to source and termination impedance not to mention other problems. If someone could point me to a source for schematics, or has any suggestions for doing this, I'd appreciate hearing about it.įirst lets call a spade a spade. ![]() Now the dumb questions: Is there a passive design that would work with a line level signal? Or an active, balanced, mono filter design in a small package, that would not degrade the signal? It would be nice to run a line level cable out of the sub, through the filter and directly to the top cab. ![]() Basically trying to avoid the expense and additional wiring of using a full crossover. I'd like to buy or build an inline filter to simplify using active subs that have a low pass filter input, but only a full range output. ![]() Mike Pyle wrote on Sat, 17 December 2005 18:31 ![]()
