    I ended up canceling my order for the EX upgrades.................and just ordering a new set of domestic cabinet natural EX’s instead. I’ve got the S2’s up for sale but if they don’t sell I might just use them for a 2 channel set up or box them up and use for surrounds eventually.

    Not sure how to hide 2 sets of speakers from the wife though. .

I turned my sub's volume down a bit. When listening to music I thought I knew very well, it sounds like there are new instruments playing in the song. Subtle clarity is improved. I'm overwhelmed by the added details. Every thing Dave has said about this upgrade is true. If funds permit, I'd highly recommend doing this upgrade. I think of my speakers as "Sierra 3's" now!
    Thanks for sharing your experience installing the upgrade kit. I have a new set of Sierra 2s and intend to upgrade by either shipping them back for the swap and new frequency read-outs, or just ordering the kits.

    Can you share how long it took you to take out the crossover and woofer and make the replacements? Did you hit any obstacles in the process? If its not too bad I may attempt it rather than incurring the cost of shipping. Thanks.

    The process is super easy, just make sure you have a plier/rachet/wrench of appropriated size and length and a short philip screw driver. I use plier and a short philip driver and is all good.

    Wow thanks! That sounds doable.

    I agree. If you know which end of the screw driver goes in your hand, you will be good to go. The directions are detailed yet very clear. I'm a rather slow and deliberate worker. The installation took about 2 hours and 15 minutes. I went to my garage each time I needed a tool. Time well spent!

    If you want to convert Sierra-1 NrT to Sierra-2EX, you just need to order the Sierra-1 -> Sierra-2EX kits.
    Yes,

    I'm the one who had this speaker specially made. I think it sounds amazing. I had the ribbon previously so that should give you an idea of how good they sound. The ribbon was a bit too tame for me in the upper treble region. For anyone with the nrt that wants to keep the dome the nrt with the ex woofer is 110% worth it and sounds awesome. Tight authoritative base, great punch. Ex woofer integrates well with the nrt.

    Does the orientation of the RAAL matter, aka, is it possible to accidentally re-install the RAAL "upside down?"

    Also, how are people protecting the ribbon while doing the upgrade? I've misplaced by protected sleeves and don't exactly trust myself not to damage them while doing the EX upgrade.

    As long as the tweeter is installed vertically (if you are using the speakers in the vertical position) - there is no top or bottom on the tweeter so there is no upside down or right side up for that matter.

    The thing with the ribbons you need to be concerned about is that they have very powerful magnets inside and will literally pull any tiny metal fragments towards the ribbon. If a particle gets past the screen, it will tear the ribbon. So, if you don't have the sleeves available, I recommend placing a piece of blue painter's masking tape over the entire rectangular opening. Gently peel this off when ready...

    Wow. Good information. Sorta like an MRI machine with the magnet! When I finally get my upgrade, I'll keep that in mind. I will keep my mechanical watch far away! Dumb question.... so the magnets are in the ribbons or are they behind the ribbons in the enclosure?
