    The instructions say if you have them, you should use them. I think it’s probably more to protect against a slip of the screwdriver than anything else. Anyway, I just slid them back on and it was fine.

    Thanks,

    Cool. Interested in your impressions once you complete the upgrade!

    Just finished the kit. Took maybe an hour or so to do both. Very simple. One small issue was the connectors for the leads to the woofers...a little loose and my pliers were probably not the right tool for the job. I debated soldering them on, but remembered my DIY days and that one time I accidentally had the iron too hot and literally melted the terminal right off a tweeter. It’s a funny anecdote on a $30 tweeter, not a $300 woofer. So I managed to crimp them a bit and think it’s good enough. I’ll check in a few days and make sure they’re still tight.

    Turned them on and two things I noticed immediately, without giving the woofer a fair chance to break-in:

    1. They are definitely warmer than the standard S2, which I prefer.
    2. The bass is huge. I also have the Buchardt S400s and didn’t think I’d find a small bookshelf that could equal their bass. Well, I think the S2-EX may be at their level.

    More to come.

    Really can’t wait to hear your impression specially against the buchardt s400

    Sounds promising! Keep us posted. I’ll be upgrading sometime this year.

I'd be happy to contribute to such a project rather than throwing these great units out.
    This would be something we would have to carefully consider. Ultimately, the Sierra-2EX will replace the Sierra-2 and sales have been brisk thus far such that using Sierra-2 cabinets for anything other than Sierra-2EX can possibly lead to inventory shortages.

    Hi Ryan - the protectors should simply be slid on or off. Instructions are listed on them but give us a call if you are having issues.

    Do you run a sub with these and if so what do you cross it over at? I’m curious if a sub is used whether the EX driver will make much of a difference in bass response with a crossover of 80hz or higher. Since both speakers should be measuring pretty flat is there actually more bass output or just lower extension? Not sure how to interpret “more bass” if the frequency response is flat for both the regular Sierra 2 and the 2EX.

    Dave, Glad to hear that your investment with SEAS in producing the EX woofer is a success!

    I am bummed that I will have to wait a bit to join the EX club, but I know it will be worth the wait.
