"Non Inductive" resistors.

I have a couple of Boston Acoustics speakers that I picked up for free at the dump. The woofers were torn, but the boxes and grills were like new. I put in a couple of Dayton Audio woofers, and they are better than OK except that the tweeter needs about a 4 ohm padding resistor.

In view of my minimal investment, I don't feel inclined to use exotic resistors. Question is...so what if the resistor had a bit of inductance? Wouldn't the resulting roll off be well above the audio range?

Tom...These speakers will never sound great, but they do need all the help they can get:-)

Its all to put into your audio file cabinet of experience and knowledge..If you ever saw the 3ft long crossover of a Thiel CS5 speaker with maybe 75 components on its board and the many poor quality resistors it would make you say to yourself WHAT IF..Tom

Yea, like "what if someone simplified these crossovers..."

Would they not be so much easier to drive and also far cheaper at the same time?

Thats what Dunlavy said to me about those other guys crossovers..Tom

Maybe that's why the Maggie MG1.6 sound good. Crossover consists of one inductor and one capacitor for the woofer, and one capacitor (implemented as a parallel group) for the tweeter. And NO RESISTOR unless you choose to insert one. This also made the cost to upgrade using top of the line components quite reasonable.

Of course Magnepanar designs and makes their drivers, (perhaps excepting the ribbon) and can play around with the driver designs to get the results they want. Most speaker system manufacturers have to make do with drivers that are designed and made by others, and then try to achieve the sound they want by complex crossover networks.

PS: Except for tweeter crossover (2000 Hz and up) I am a firm believer in low level electronic crossovers and biamplification.
