    Bi Amp L300?

    Is it feasable to Bi-Amp the L300 using the Ashley XR1001 crossover network and would it be advantagous or not?

    Bi amping is generally accepted as being ' a good thing ' It does allow you to choose amps with different attributes for the LF and MF/HF sections. For example a nice big Crown to run the bass and a Class A sweety to run the top.
    Just my 2 cents worth , have fun.

    and don't forget the primary improvement of bi amp that is according to my knowledge the removal of the series resistance of the coil in the low pass section

    Thanks for the info and it would be nice to run the JBL 3133A network but I don't have two and there aren't a great deal of them for sale out there. That leaves the Ashly, is it a reasonable alternative?

    Even with the 3133A networks you still need the active crossover. I'd consider building 4313B's (the forum member, not the speaker) updated L300 network in a Biamp only version. All you need the full HF section and the low pass portion of the MF section. Protect the LE-85 with a 20 uF cap for DC and other nasties, or simply use the full MF section.

    You will have to do a search to find the network, but it was included in a recent post.
