    I contemplated only cutting holes for the internal connections leaving finger room to unclip but by the time i did the drawing template i really didnt cut out that much more than what was needed.
    I have had drammas with overlapping materials with my SRS and more seals or glue would have most likely been needed between them.
    The plates that the crossovers are attached too are extremely solid and well braced .I added a little dynomatt internally where possible(3 square "s max ech".
    It reminds me of the SDA SRS-1.2 plate.

    I wouldn't add braces to the front bezel but if it was originally braced i would definately check and add extra glue,re glueing my braces and Larry's rings in my 2 X SRS'S in my theatre lowered my noise floor and added more depth and air.

    SDA CRS 4.1 TL 20 hrs in and they sound amazing.

    ohhh,i forgot to also thank Larry,who within a nites notice supplied the last remaining set of rings he had for my CRS when i asked in the forum around 7 months ago.
    Thank you Larry ,i would never build a set of polks with out your rings, these put them up on another level instantly!
    cheers Mate

    I have to say that was a ballsy mod cutting that hole in the cabinets, they look awesome, and there is no copyright on my speaker stands, or rings for that matter, if one has the means to build them, build them!! I’m not one to get **** because someone copied an idea, it’s a hobby, and these speakers are how old? 30 years?

    The stands look great, along with the crossovers, I love the braided speaker cables..

    Enjoy..

    Try flipping the passive if you think you may have lost a some internal volume with your new mods.

    That's awesome. Sometimes smaller speakers are easier to dial in to the room

    Glad to hear 😊
