High pass quality to mains uisng Velodyne DD subs

Hi,

For those who have incorporated one of the DD series subs into your two-channel system, did you use the line level high pass filter from the sub to your main speakers amp?

I have two sets of outputs from my preamp, so I could run one set to the sub and one set full range to my mains. I was just wondering if folks had experienced much degradation of signal going line level from preamp to DD to mains amp.

Theoretically, I like the idea of the high pass filter.

Getting ready to set up my dd18.

Regards,

Jerry

I think Rwwear means he doesn't like the idea of having the mains encumbered by a high pass filter in the signal path. It would be interesting to hear the results of trying both methods.

I really think it depends on the main speakers you're using and what your aim is in using crossovers.

In my home theater using the processor's crossover does wonders. The active network seamlessly blends my NHT satellites and sub creating a very coherent movie experience.

However, in my 2 channel rig I've found using any kind of crossover destroys the beautiful midrange of my ProAcs. Upper and to some extent midbass contribute to the way we perceive overall midrange, and the midrange of the ProAcs suffers greatly even if I set the crossover to 35Hz. The associated equipment I've chosen enhances that midrange and any attempt to place a filter before the ProAcs recesses the midrange and compresses the sound.

However, if a more balanced, neutral sound is your goal, use of a high pass filter could depending on the speaker and intent be very beneficial.

Like Dlanselm, after trying to integrate monitors [in my case ProAcs] with a sub I have since gone to using full range ProAcs without a sub.
