High-pass line filter to relieve main speakers from low frequency
I am doing just what you describe in my strength to roll of the bottom end below about 65Hz. I am using a Pair of Miflex KPCU caps for each channel (balanced connections). I think the improvement in sound quality is pretty subtle, but it does seem to have a bigger effect the louder I play the system. |

Your observations would be consistent with the theory: the louder, the more energy and distortions, scaling up exponentially with perceived loudness. |

They make inline filters (low and high) from 20hz up to at least 100 hz and down, THEN 15khz and up. AT LEAST.. It's a pro application, but works very well.. No need to add anything but the filters you like PRE power amp.. It won't affect the passive OX in the speaker.. Just the signal it receives from the amp. No SUB involved with steeper slopes like 24 or 48. The BOOM goes away and the timing (which is the problem) will become coherent. Reduced distortion, muddiness, bloated bass ALL goes away. Room treatment, main and sub decoupling are the real eye openers too. BUT limiting bass to the main is the BEST place to start, decoupling is right there though.. Room treatment is just the polish on a good, from ground up design.. Regards |
