High pass quality to mains uisng Velodyne DD subs

Rwwear..."unincumbered"??? The idea of the crossover is to free the main speakers from the burden of unproductive LF cone motion.

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.

Right Gunbei, thanks. Extra electronics in the signal path ya know.

Looks like no one has A/B'd this. Within the next few weeks, I'll be able to give a try.

If I find that the higpass is benefical, but a little noisy, I may go for an outboard crossover like the the vandersteen m5-hp. The savings on long rcas's of even moderate cost would about pay for it.

Thanks for the responses.

Rwwear...Any degradation due to "extra" circuitry is theoretical, and could be expected to occur only for inferior electronics. LF cone motion is actual physical reality...not theoretical. It causes Dopler modulation of higher frequencies, and requires the driver to electically function over a large range of cone excursion that would not be present if the LF were filtered out.

By all means try it both ways, and do what you prefer. In all likelihood you will hear no difference with the typical lightly driven home audio equipment, but a Pro Sound rig, driven to its maximum capability, would be a different story.
