Spatial Audio Labs


I have owned the older Spatial audio labs design 
I don’t see much on the Newer X3 and X5 models .
I heard them a few times at audio get together s  several months ago 
and being 97 db efficient, with power Bass below 90 HZ , the open baffle design seems to hav3 come a long way , the superb to my ears Beyma Tweeter-Midrange is very special in the designed-wave guide 
and venting out the back from 1 khz - around 25 khz  with Nothing in the Xover above 1 khz 
I was very surprised only 2 capacitors and 1 inductor in the entire Xover . I heard them with the upgraded VH audio Odam capacitors . They sounded at least as good or better then any $15k + box 
speaker . If anyone owns these, or has heard them in depth  pleas3 share your experiences

I just ordered the M-3s I’m planning on using them with my Hegel H390. I will definitely leave some feedback after the arrival..
I owned them from August of 2019 to August of 2020. I thought they were very good and did all the audiophile things well. Very open and the bass was excellent in definition and extension. But ultimately I wasn’t happy with the 12” driver as a midrange. I didn’t hear the texture and nuances in vocals and brass instruments that I wanted. All in all, a quality product that just didn’t move me emotionally.

I moved on to the Klipsch Cornwall IV. I’ve been back and forth with horns for years so I took a chance on them and it paid off. Much more texture and vibrancy in the midrange. Bass isn’t quite as good but I added a pair of 15” subs to carry that.

I ran a set of X5's for a year or so and really liked them.

I have since found a set of AZ Crescendo MK2's and have them in the system now.

The Spatials are a very good sounding speaker and actually sound better everywhere in the room and at low listening levels.

The MK2's sound better in the sweet spot but not by much. I did run a pair of SVS 3000's with the X5's and also with the MK2's.
I have a pair of X5's. They are the most revealing speaker I have ever owned, which is a bit surprising given how relaxed they are. Any upstream changes are clearly evident. The tweeter is probably the most natural sounding in my experience. Properly setup there is a fairly narrow sweet spot, enough for two people. The tweeter's vertical dispersion is somewhat limited - you will notice as you sit down in the sweet spot how things come into focus. I am currently trying to get a more layered depth to the image. I am waiting for an Aesthetix Romulus to arrive, replacing my PS Audio Directstream Sr. I did audition a Pass XA25, which did indeed provide the depth I was looking for, but there were other issues with it, so back to my Rowland 535. Like any dipole they need to be out in the room a considerable distance, mine are ~4 ft from the front wall. All in all, they are really satisfying speakers.
The most difficult part of a loudspeaker to manufacture is the enclosure. The reason big ESLs are relatively inexpensive is that they do not have one. It is much easier to make a simple plate so Spatial can make a very competitive loudspeaker and probably make more money doing it. I myself have made several open baffle speakers for friends pairing them with sealed subwoofers which brings us to the problem, bass. There is no sub bass. As the wavelengths get longer they simply cancel out. Above that bass performance depends entirely on the room and how sound bounces around. In the right room these speaker can sound very bass heavy. Distance from the wall is also important. Having measured X3's I can tell you there is no way anyone will get remotely flat bass response out of them even with room control. But bass can be very difficult to evaluate. people can "hear" the note even with the fundamental missing. 
Our brains fill in the blanks. 
The best way to use these speakers is with subwoofers crossing up a bit higher at 100 Hz at least. This will dramatically clean up your midrange and give you controllable bass as low as you care to go. This is not much different than any dipole loudspeaker as they all have the same failing.
