Vandy sub owners-crossovers for 2WQ


Given a amplifier with 50k input impedence and Vandersteen's recommendation that the filter be set at the next lowest value ( according to the WX-2 box )which is 33K, my question is: If the amplifier is an actual 50K input (as is the case with FET transistors used in the input circuitry)why would you want to set it below the 50K? The instructions say set it for the input impedence---very confusing)If you want a 80hz high pass wouldn't anything but a 50K alter this? Also, does anyone have the formula for computing capacitor value for various input impedences to achieve a 6db high pass @ 80hz? Thanks

Thanks guys. I noticed in the owners manuals I received with both subs that the section about the filters was repeated twice. One section said next value down period and the other said try one up, one right on and one above. I mean two complete sections. Go figure. Anyway, the one down sounds a little on the heavy side and the one that matches the impedence sounds a bit lean unless you run the sensitivity control up a few DB. One over is lean period. I'm trying to match the things with his speakers(3A Sigs)They blend seamlessly but I can't seem to get the output right on. Any insight you guys can provide will be greatly appreciated. Any little secrets? Sometimes the dealers remind me of car salesman, they just sell! I bought the subs new from a dealer on the other side of the country, Aris Audio in Utah. Scott is a really nice guy and I'm very satisfied with the way he handled the sale. I'm in SC. He told me to try and match what sounds best(like yall have) and go with it. I guess that's about all you can do. I thought I might try e-mailing Richard Hardesty and see if he could enlighten me. Hopefully he has a secret since he seems to be a Vandersteen guru. I've talk to Richard V. on the phone and in person. Most of the time he seems OK but I did notice he gets testy---maybe its harmones!
