I have spent a ton of time comparing the Luna with the Sierra-2, using an 80Hz crossover with a sub. They sound very very close, sometimes indistinguishable - but I can't quite put my finger on the differences. There is a sweetness to the mids of the Luna that I really enjoy - it very well may be due to the lower mass woofer or it could also be due to the slight differences in frequency response and dispersion between the two - my experience tells me it is a combination of things. What surprises me most is that I really enjoy listening to them full range without a subwoofer - the lack of deep bass causes one to focus more on the mids, which I find to be exceptional and just so musical - and there is often surprising bass, thus causing a bit of a surprise when looking at the size of these speakers.
As I have mentioned - these are just extremely FUN speakers
Perhaps Curtis, Mike or Mitch will also add some comments.
Hi Nate,
At 7 ft distance, I recommend keeping the speakers within +/- 15" of ear level. Assuming your ear-level is around 38" while seated (typical) - mounting them at a height of 53" off the floor or less is ideal (this keeps them within a 10 degree vertical off-axis angle). You can go as high as 60" to keep them within 15 degrees vertical, but for absolute best performance - 10 degs or less is best.
Of course, this is for flush mounting, the vertical listening angle changes if you use a bracket and angle them downwards - thus opening up many more options.
formula to calculate this is: tan(desired vertical angle) = x / distance to the speaker.
Solving for x gives you:
x= 84" (distance to the speaker) x tan (15 degs)
x (height above or below ear) = 84" x .2679 = 22.5"
My father in law ordered a pair of Luna's a while back so I'm looking toward to checking them out soon! Well done Dave and crew, they sound like quite the lil speaker😀
Thanks Dave for the calculation info. That's handy to keep in mind.
What about wall mounting the Lunas upside down? The measurements from above look a little smoother than from below. I'm thinking since I'm going to place these above ear level, I might want the tweeters closer and more in line with my ears

Based on our audition, I agree with Curtis. Very similar to the Sierra-2 with a bit less bass. The smaller, lighter woofer on the Luna, might give it a very slight advantage in the mid-range but I think it would be difficult to hear without side by side comparison in a well treated room.
I've already got a pair of Sierra-2 for surrounds so I won't need the Lunas right now. But I could see using them for a separate set up in the bedroom or office. I think they would probably sound amazing for a desk setup.
