    The Sierra-1 is the same cabinet as the 2 and with the NrT upgrade it's the same dome tweeter in the Towers, so all that is different at that point is the woofer, which has to be different from the one in the Sierra 2, because that one was designed to play much higher in order to crossover high enough for the RAAL tweeter. Go with the Sierra-1 with NrT.

    I'm not aware of any kind of screwing-in sanus stands. You generally just want to use something like Blu-Tak or just silicone bumpers/feet for setting them on the stand. I've never seen it be necessary to screw a speaker into a stand, nor would I recommend it. Using something squishy (Blu-Tak, silicone, etc) gives isolation to any rattling that might happen.

    Yes, by request - we have built this for a few different customers over the past few years. As can be imagined, performance is excellent. However, there is no cost savings associated with this speaker - retail pricing would be the exact same as non-sale retail pricing for the standard Sierra-2.

    Please feel free to send us an email if you are considering this design.

    Domestic cabinet Sierra-2 finishes are the same as is available for our Sierra Towers:

    What is the difference in tweeters? And what is the effect of adding the tower tweeters to the Sierra 2?

    Wait, I don't understand. What would be the point of getting a Sierra-2 with the NrT tweeter? Wouldn't that just be the same as the upgraded Sierra-1, but with the "wrong" woofer? I feel like I'm missing something here.

    Better midrange and transition response than the Sierra-1 NrT, but doesn't play as deep.

    We have made this speaker for a few customers of ours as some prefer the sound of a high quality dome tweeter over a ribbon, but they also wanted more detailed mids and a faster transient response than what the Sierra-1 NrT woofer is capable of.

    Dave, just out of curiosity, have you ever built a Sierra tower or Horizon with the Curv woofers from the Sierra-2? Just wondering how something like that might turn out.

    There is really no point as the dedicated mid in the tower is a better overall midrange driver and the bass woofers in the tower extend quite a bit deeper. The Sierra-2 woofer is about as good as it gets for a driver that needs to reproduce both mids and lows.

    That said, I have been working with SEAS on a dedicated 6" Curv midrange, but, so far, the performance is only marginally better than the current midrange driver we use in the tower. The cost, however, is over 4x higher, which would force us to raise the price of the towers by quite a bit and the price increase isn't justified IMO.

    Fascinating. Can you use the stock Sierra-2 crossover for this, or does this arrangement require a new one, something in between the S1 NrT and the S2?
