    Default Polk Audio LSi7 Crossover Modification Thread

    I don't see too many people modifying these -

    This was a lot of fun. After messing around with different ways to build crossovers and ironing out the details and materials I think this is pretty close to how I am going to start building everything...

    Looks good Trey. It might be a good idea to use thread locker on the all thread. I can see that the nuts could move over time with all the vibration inside the speaker cabinet.

    Thanks guys! :)

    I have considered thread lock or some form of locking nut for that reason but I have had customers blow resistors or an inductor (some like it a little too loud... ;-P) and I designed the crossovers to where you can remove the front plate to maintenance the resistors, hence why everything is mounted underneath...

    I have been researching the last year particularly with my Monastery mods different ways to secure, fasten, build these but I look at long term maintenance/upgrading as a first priority. If* the owner wants to upgrade further how it then be taken apart just as much how I am putting it together. My second goal is making it as easy for the owner as possible.

    I hope to here shortly start building the LSi series with aftermarket inductors on the stacks, I have the layout, I have the material now that can support is just gotta do it! :-D

    Given your maintenance/ability for future upgrade considerations, what you would want is the blue threadlocker. It allows for disassembly. The red locks things in place permanently.
