Brad,
Don’t forget we have Spock’s younger brother. Whom is 120% Vulcan but does a similar face gesture just to taunt Spock!!!
Spock was 1/2 Vulcan, so I get that meant a single eyebrow for Spock?

I have not bought speakers new in… well… let me count the decades.
But I committed to a bit of a project this week.
(The worst that can happen is that they get the passive XO outboard from the speaker.)
And the passive XO version seemed pretty to get the olive score of 6.something. So it is not like there is much deviation from optimal.
They probably do not need more headroom which a bi-amp would give, as they already effortlessly play too loud to hold conversation.
Who are the active-XO and bi-amped members that can offer some advice?

- Stumbled upon a piece Tasmanian myrtle
- Alan is graciously allowing me to try a set without the passive XO.

- I have a pair of FA502s which I can use (They eventuallly will be ending in subwoofer boxes)
- I’ll likely use these to do ythen DSP part, unless there are some good reasons to start with something else?
- And I have an APL DSP which I could use.
- Which is FIR based
- Are there some other DSPs to consider for this?
- I’ll want to end up with good step function response and impulse response, in addition to the FR.
- And I can always use something like “room perfect” to beat the room into some submission
Hello @Holmz,
Just for your reference, my project on multi-channel multi-way multi-driver multi-amplifier stereo audio system would be of your interests.
You may find here the latest setup of my system as of January 25, 2022.

Looks like that Octo is solely doing DAC, and the filtering is done on the computer.
I have some reading to do, and Octo is showing no DAC8s in stock.
But I can work my way through it.
Looks like a great speaker. My guess is that March Audio won’t send one to Amir to measure, unfortunately. I’ll check out Erin’s video.
Just for your info;
I wrote here and here;
- Information exchange is in progress after this post on this remote thread regarding FOCUSRITE Scarlett 18i20 2nd gen (and 3rd gen) as well as MOTU UltraLite Mk5; it looks both of them support simultaneous sync 10-channel DAC processes: #449

(I get the nuance of the comment…)
But what is the difference between Amir and Erin?
Both names are 4 letters long, and two of letters are the same, and they both “rock a Klippel”.
If the Klippel was not a repeatable measuring tool, then they both made a mistake.
I have actually sent a speaker to Amir to measure.
And I patreon’ise Erin.
I have equal confidence in both of them doing reviews.
And I believe that they compare notes and techniques.
But it is also entirely possible that their mics and calibration sound be some fraction of a dB off and the difference between could (maybe) be a dB somewhere.
(Likely it is better than my ears do it)
When I first heard them I thought, “These are really nice.”
Then later that day I thought, “Holmz you moron, you are totally biased towards the driver and design… it is mostly in your mind. Wait for some measurements.”
I already have some good speakers, my first set in fact.
So this is new ground for me… and I would not have likely made a swap without understanding both the speakers from measurements that Erin did
These will likely be doing digital front end, Class-D, and sort of barebones.
And the legacy system doing a combo of 5.1 and 2.1.analogue … Amir did the measurements on its center channel.
How could I not like, and appreciate, both of the them doing this sort of work?
Any past communication problems, are not present in the Klipple measurements, nor in the sound.
No nuance intended. I just know that Alan is no longer a member here for whatever reason and figured he wouldn’t send equipment here to be measured.

Yeah I work with a bunch of engineers, and most are pretty smart.
A lot has strong opinions, and can be passionate to the point of being difficult to work with.
(But HH, the Dali Lama, for instance, is not an engineer… Nor are the HR ladies.)
I was asking a colleague about a vexing fellow I have not met, and he said, “He is a lot like you.”
I said, “oh _uck.”

Understood!
In any case they sounded good.
It was not surprising… or maybe I am surprised that my ears thought that they sounded good, and then the measurements confirmed it.
(I do not trust my eyes and emotions to be rational.)
But it is hard to both hear it, and see the measurements, and not think… “Crickey!…., these things ARE kind of special.”
Hi, how do you like those tripod stands? are they stable or easily tipped?
Let's refresh this thread with news from Alan March posted on Facebook.
"Just wanted to share the Klippel test results from our newly updated Sointuva AWG speaker.
Now using the Purifi Aluminium 6.5" woofer.
Improved frequency response flatness and low frequency extension. Super smooth sound power, early reflections and directivity index. Reduced distortion.
FR 75Hz to 17.5kHz = +- 1.2dB
F3 = 37Hz
F6 = 33Hz
F10 = 30Hz"
"(...) testing performed Warkwyn in the USA. Many thanks to Jason and Kent."

Any pricing?
Looks as though March decided to tradeoff sensitivity to get better low end extension.
Pricing not disclosed yet. The previous model WG is for USD $3,647.68. The new Aluminum woofers are +40 euros more each woofer on Soundimports. So component price should be lower for OEMs. So end product probably closer to 4k usd.
Wow. That’s pretty close to ruler flat and with almost perfect directivity to boot
If I were to buy new speakers today, this would be my choice. Amazing!

The cabinet options + performance make these a great choice. I have an earlier pair built in birch ply that came out really nice.
Wowowow! That very nice graphing for those speakers. Amazing.
