I would consider any active electronic device between the monitor path and power amplifier to be an additional filter. The end user must decide if the improvements are worth the losses incurred.
Back in the mid 1990's I was working in a larger dual SSL facility in the Caribean. The owner had installed an expensive, famous "English" 4x10 system, soffet mounted. A BSS stereo crossover was used, modified for the crossover frequencies.
I was wondering why the playback was so muted, a total lack of low level high frequency details. After reworking the entire room, I asked if I could take on that playback as I was not hearing the results I got in other rooms.
Several decent film caps, a bunch of excellent opamps and the removal of low end electrolytic coupling capacitors changed everything. The owner needed proof so I only reworked the right side.
Then that tired old boring, sinking ship movie sound track was played. Next a bell tree pops out on the right side, nothing out of the left. The owner looks suprised and says, "what's that?"
I say, "that's the music your playback system and it's designer think you don't need to hear".
"Can you do the other side now?"
For simple 2 way systems I prefer an passive solution using the finest air foil inductors, wirewound precision resistors and premium exotic film caps. The parts are very expensive, however. I have the same amount invested in the crossover parts as I spent on the speakers new. It was all very worthwhile.
