    In with 42 ;)
    So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

    Dave, are you planning to sell them or they for a customer?

    Add another one to the ranks of the Hearing Is Believing crowd. Don't wait so long until you post again ;), and congrats on the upgrade.

    Do I need to mount the crossover plate differently since the old inductor is connected via risers and attached to the bolt on the back?

    You can make a new mount, or just leave the old spool and connect the leads to the new inductors.

    Cool, I might reach out to you soon to do that. I still have your business email. Thanks Dave!

    These are basically them same as my CRS 4.1TL's Dave made foe me as I used all Sonicaps also. and the Super Q inductors.

    So I now they are special ;) as I current have them in my SDA 2B's :p

    Some day I'll have Dave fix up my 2b crossovers...but I wanting till he has his foot problem fully healed and more time on his hands as I can switch between my SDA as needed for now!!

    Codycatalist - I don’t know what you’re running for an amp, but if you get the new inductors make sure it has enough grunt to handle the lower impedance.

    good stuff here. My Speakers are now 4 ohm speakers and not 8 ohm after the TL mod!

    To use the Super Q inductors they have to be tuned or turned down to the correct value..which isnt for anyone to do . Dave knows how to do this I tried once on a cheap pair without much luck burning off the coating and trying to turn it down and measure it correctly... not for the faint at heart.

    Yeah I know. That's why I didn't do it originally. I now have an Adcom GFA545 so it'll handle the load fine. :)
