Watching Paul’s video today I think the armrests on the chair he’s sitting in… just might be a close match to the AN3 stands. Coincidence?

The two piece design is beautiful. I prefer the one piece based mainly on looks with some to the single piece being more stable (and easier to align).

Indeed. One piece design is certainly more stable. I just wanted to offer another option, maintaining same attachment method. In fact, countless design options come to my mind, even if I am not speaker designer. I just like to explore different design options (and it is fun).
Steven, as you know I have the equivalent of the PMC BB5-XBDA, therefore I have a pair of actively driven 15" drivers. A track that shows the system off well is by the O-Zone Percussion Group, album La Bamba, track Jazz Variants (the action starts at about 1. 36s into the track). Maybe if/when you hear this here I’ll convert you into liking bass!
Dan.
P.S. I have the CD of the track but also saw that it’s on Spotify.
Nice concept, nice design. If there are threaded inserts under the bass module,
after market isolators could go there and if stability was an issue, the point of
floor contact could be widened with a bar and spike approach. Maybe Chris
has this covered, I saw some mention of this earlier. In any case, a good looking
option.

That is exactly what I intended with this design. Threaded inserts or direct thread in metal plate. To allow to exchange default footer for aftermarket one. For example Isoacoustics Gaia (which I had a great experience with).
I’d prefer a standard solution like this, without that kind of effort needed.

Exactly the same design comes first to my mind. Very simple, yet good solution. When PS Audio wants to be different and attach stands on side panels, various design issues has to be solved.
I believe they have 1/4-20 holes in the bottom, so no need for making holes in the sides.
Well, in speaker design, there is something called Hoffman’s Iron Law. The efficiency of a speaker system is proportional to the box size and the cube of the low frequency cutoff.
In short, pick two of the three: box size, efficiency or low frequency extension. Because it is the cube of the low frequency cutoff, in order to have a system with the same efficiency but plat lays an octave lower (20 Hz vs 40 Hz) the box size would need to be 8X larger. This is dictated by the laws of physics.
With an active system, we can make reasonably high sensitivity driver s(for good midbass punch and headroom) and then put them in a more modestly sized enclosure and use EQ / correction and allow the rest of the speaker to be higher sensitivity as well, as the woofer section is what drives enclosure requirements and system sensitivity.
This is often why other manufacturers have specsmanship mis-stating their sensitivity and bass extension a great deal and why some of the measurements in places like Stereophile and Soundstage can be rather eye opening.
That being said, our Stellar and Sprout speakers will be passive designs and so we’ll have some great options for people in that regard as well.

No active subs in Stellar? So they might be EUR 6000 or even EUR 10000 (estimation) cheaper than the AN3’s but in order to get the bass fundament I need to add a pair of subwoofers which brings me back close to the AN3’s in cost again but occupy a lot of extra real estate (I don’t have). Hmmm.
I had certainly hoped the active subs would trickle one way or the other down into the Stellar series.
Exactly. An “outrigger” bar or plate attached via the threaded inserts,
with supplied threaded spikes, would look good, work good, and allow
upgrading if desired. A easy win I would hope.

Well, they are being designed as full range but passive and so no need for subwoofers.
I do like the adjustability of active subwoofer systems but I’d like to offer some boundary adjustment in the passive crossover on the stellar line to accomplish some of this.

Would an active (Balanced) crossover be possible in a small box? That way we would still have possibility’s to actively drive the Stellar speakers and customers would purchase a plethora of Stellar amps rather than on or two.

I am surprised you are entertaining the use of measurements for any validation. To quote Paul directly:
You can still have the advantage of an active system but with external components. Have you considered an external enclosure for the active components?
There are plenty of measurements you can do on a speaker that will tell you if it’s good, average or, crap.
I don’t need convincing, I simply assumed that Paul’s comments reflected the PS Audio speaker design philosophy when he called speaker measurements ‘bull pucky’.

In this case I would disagree with Paul. And I’m betting Chris does as well. You don’t manufacture ANYTHING without measurements. Unless you’re selling snake oil that is - then it really doesn’t matter.
Number three for me please.

If you look at the context of Paul’s quote, it says nothing about measurements. It says that you can’t tell how a speaker will sound based on measurements. I agree.
