    All towers shipping as of today will have this small label on the back of the grille.

    It is completely invisible from the front.

    Really appreciate the feedback on this!

    I didn’t want mine taped to the fabric, nor did I want the tape adhesive possibly interacting with the finish. I just used a simple label maker a few months ago and trimmed (not pretty, I know).

    Funny how we came up with an almost identical design independently.

    I was playing around with Sierra Tower room placement today, took the grills off and noticed one of the magnetic grilles was on upside down too!! Not sure for how long, but there was no indentation in the surround just a little dust mark which was hard to even see. It was then that I noticed the TOP sticker on the back indicating orientation. I have to say I like John Galt solution with different polarities top and bottom. My experience is that if it CAN happen, it WILL happen. I did a search to see if anyone else had this issue and here I am. This little issue notwithstanding, I have had these Towers for about 9 months now and love them more everyday.

    Perhaps we should include a small note with the speakers regarding this? The problem with using different polarity on the top and bottom, and I have already discussed with our cabinet maker, is that if the production crew makes a mistake, there goes an entire cabinet. With using different polarities for the magnets, the chances of one of the guys inserting the magnet wrong is significantly higher.

    With our cabinets, because there is no veneer, the magnets are inserted into the front baffle from behind and then epoxied in. A magnet installed with the wrong polarity, if not immediately caught, means that cabinet is now useless.

    IMO, makes sense to minimize the risk of scraping an entire cabinet if the production crew makes a mistake with inserting a magnet. A note with the speaker, either separate or in the manual, should suffice.

    I was trying to think of a way to "key" the grill and the cabinet in a way that would not allow them to orient any other way than the right way. I am not sure if this is plausible, but what if the bottom magnets were moved up between the two woofers. If someone tried to apply the grill upside down it would not stay - in other words offset the magnet locations top and bottom thus providing that keying. Just a thought. I just know that no matter how you detail something like this people will miss it somehow (haste, lack of attention, fatigue, etc).

    This is something we are looking into. As it stands now, the magnets are not symmetrical from top to bottom. When put on upside down, only 4 of the 6 magnets make contact - but, obviously, even with 4 making contact it is still enough to secure the grille.
