Subwoofer Set up Question

I am thinking of hooking up a Velodyne HGS-12 into my system to give my room a bit of a bass boost (Coincident Super Eclipse 3's). I do not want to use the internal crossover in the subwoofer and am thinking of running the speakers full range for my application, two channel listening. My preamp has 2 outputs so feeding the sub is no problem. Any thoughts?

Thanks very much for any input!

Well, you can connect it that way but you still need to adjust the LP filter, level and phase of the sub. You will also need to place it and/or EQ it. Hard to advise further as you need some additional tools to do this properly.

Doesn't the Velodyne manual advise?

Your setup ideas are exactly how I do it! I'm using a pair of ADS 1590/2's full range, and using the high level input on my Velodyne 1500R, and set the crossover to 40hz and the level to whatever sounds good to me. I don't know how low your main speakers go, but you can adjust the sub's crossover to whatever your speakers low point is. The sound is incredible. Go for it!

If you by-pass (defeat) the internal x-over in the sub, you'll be running both the main speakers and the sub full range. They will surely overlap for a few octaves. It is theoretically possible that this will work, but, as a practical matter, it will almost surely be a disaster.

To be clear,

You can certainly use ONLY the "high cut" function of the internal x-over in the sub to roll off the high end response of the subwoofer without using the "low cut" function of that x-over for your main speakers, per Sid 42. Many people report that this can work well.
