The Sierra 1 is a nice-sounding speaker. It sounds a lot like the PSB Alpha B1 speaker. I think the PSB sounds a bit better, though, and sells for $299, whereas the Sierra 1 sells for over $800. IMO many less-expensive speakers outperform the Sierra 1 in every way. The same is true of the Nola.
A MUCH better speaker than either the Alpha 1 or Sierra 1, IMO, is the Monitor Audio Bronze BX-2, which sells for $489/pair on the Audio Advisor website. It also goes down to 42 Hz; in addition to sounding better in every way, it has much better bass response. This is an EXCELLENT speaker!! (see the Audio Advisor website for specs and details)
Another one that is much better than the Sierra 1 is the PSB Image B6. It sounds better and has more bass, and is $549; another excellent speaker.
Both of the above speakers have a 6 1/2 inch bass driver and have better bass than the Sierra 1, which has a 5 1/4-inch. The Sierra 1 specs claim it goes down to 39 Hz, but their own frequency response graph shows that it is 3db down at 46 Hz, so 39 Hz is nonsense.
The Nola Boxer is very comparable to the MA Bronze BX-2; they have very similar sound characteristics and capabilities. I have no idea why one would spend $1500 for the Nola, however. That is a ridiculous price for that speaker when there are many that better it for less than $800.
For $1200, one can buy the Dynaudio Excite X12, which is worth $1200! It is incredible! It has no competition at that price, IMO, if you want a small speaker rather than a tower speaker. It is truly an amazing speaker.
If the Dynaudio interests you, I suggest that you read the recent Stereophile review on it. Since you are apparently prepared to spend that much money, it should be of great interest indeed.
For $1300 you can buy the excellent PSB Image T6 tower speaker, however, which is another story entirely.
