Today on Amazon you can buy a PAIR of KEF Q150's for $300. DIY a better cabinet for a 2-way or add a woofer and cabinet for a 3-way. Several diyaudio threads developing better crossovers too.

I prefer those with imbedded tweeter horns; ie beyma's, and Celestions (with common motor design). Although the Celestion is a bit more to deal with.
The price has gone up significantly since I bot my pair. Not inexpensive to begin with, but imo worth passing on another build or three…
They don’t have the ‘moving waveguide’ issues as the non-horn loaded coaxials. Nor do they have a horn sound that I perceive, maybe biz I tend to cross in my builds the mid to tw outside of (above) the high-ear sensitivity range.

That’s what AJ’s Soundfield Audio Monitor was - KEF Q100 coax (in some respects nicer than the current Q - no metamaterial tweeter damper but a nice cast basket instead of the current stamped one) + 8” woofer in the old (and missed) PE .75 cabinet with a PE BASH 300 amp. And they work really well!

That filtered FR graph has an aspect ratio of 60dB/decade!
Sorry - I know dB and decade, but I don't understand this.
I'm comparing it to 25dB/decade, which is the standard used by VituixCAD for printing most graphs.
Friends working on the academic side of perceptual audio also use 25dB/decade and 20-20kHz as the default view. Same with friends at Bose and Harman/JBL. A lot of the fundamental Audio Engineering Society publications used that early on and the choice stuck.

Or the refurb Q1 Meta for $350
What's not to like? (other than the $750/pr price tag).
How far back must one listen to these things so that the HF Horn doesn't interfere with the sound?

The Beyma vs Seas is not an apples to apples comparison. Scaling of the graph, smoothing, and there is a crossover all advantiges given to the Beyma.
here is the Seas with a crossover:

I'm not trying to argue one over the other but I do think we need to try to give them a fair comparison. I would love a chance to play with them both.

Thanks.

Can't wait for the community to analyze the analyzer . . .
I'm not sure I'm the guy to analyze the analyzer (maybe Amir at ASR will?) but mine arrived a few days ago. Hoping to open it this weekend.
