    Not all the time, but some of the time. I use a 2 lb air core inductor on some applications, and if I put this inside a little bookshelf, it can take up to 20% of the internal volume.

    If you're worried about adding inductance, you get more inductance per metre distance with the thicker cable you use between the amp and the XO, than with the thinner cable you can use between XO and tweeter.

    Exactly right. And if you twist the pair of thin wires together going to the tweeter, you'll get inductance even further down. The capacitance in that twisted wire will be at least one if not two magnitudes less than the error in capacitance due to the tolerance in the series capacitor for the high-pass filter to the tweeter.

    My experience has not been for better bass response (sometimes it worsens though not usually). Length of wire and possibly connections are something I have definitely experienced a downgrade of the sonic signature. The end result after upgrading the components and going external yields a sonic signature that trumps (by far) any additional wire or connection inferiority.

    Do you agree or disagree with this anonymous posters statement or not? Please do not pontificate. Serious answers only, preferably with first hand knowledge.

    The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.
