Open baffle speakers

 so base is not really an issue. 
 

That’s really cool. One question, how is the bass?

nzastro , where can i see pics of your compact baffle speakers?

@bache you keep talking-down open-baffles, and saying "measurements", "measurements". So here you are, in-room measurements from the speakers I made, including open-baffle subwoofers to fill-in the lower octaves using REW and calibrated mic...

As you can see from the graph title, these are a stereo pair of Linkwitz LXmini's complimented with a stereo pair of Linkwitz Phoenix (alt) open-baffle subs resulting in a fairly flat full-range response. They are preamp'd, crossed-over, EQ'd and amplified with a pair of Hypex FA123 (one FA123 mounted in each of the Phoenix OB-subs). Why a stereo pair of subs - "don't you know freq's below 80 Hz are mono to the ear!" I say BS - stereo is stereo at every freq, and if you want to listen to mono bass - do your thing (but don't complain to me when it doesn't sound or measure the same). Regarding the subs... they are extremely articulate and 'fast' enough to keep up with the LXmini - my experience is anything less (sealed, ported, slotted, etc.) is less. What is the (alt)? While I encourage everyone to read Siegfried Linkwitz recommendations on driver selection (and every other topic)... "alt" means 12" Peerless Tymphany XLS830500 drivers made in Denmark (instead of whatever where the original recommended drivers). Each cabinet (of the stereo pair) receives two of these drivers mounted front-to-back and wired out of phase to cancel even-order distortion and provide inertial balance of cone mass. This is what the system looked like. I was testing-out a Denafrips Ares2 at the time - it added no appreciable benefit. Notice none of these speakers are very far from the front wall (the system is in a 600 sq.ft. bedroom) and plays louder than I want...

I read a lot of arguing which is typical on this platform (and sad for the self-proclaimed mature and skilled in the room). There are many ways to acheive audio bliss. For me (an engineer), same as motorcycling and other hobbies, joy comes from the journey more so than the destination. I realize many (maybe most) folks listen for the music; meanwhile, I listen mostly to the system. How well does it put me on the stage, convey the emotion of standing amidst the musicians and instruments first-person - instead of in the front row (listening to microphones, switchboard, amps and speakers). Long ago, I discovered that elusive realism comes from dipoles (same as instruments). I've had so many different speakers (e-stats, ported monster coffins, stand-mounted, etc.) in this room and so much gear (various amps, so many DACs, multiple power conditioners, expensive cables, etc.) and nothing out-does the current configuration: LXmini + Phoenix(alt) subs source is my wife's old (broken screen) Samsung phone running DeX outputting HDMI to the Hypex amps via Coax audio stripper. An invisible system that delivers video and spacious 2-ch audio flat full-range response. Why does it sound better than everything in the pile of abandoned speakers and gear that still occupies space everywhere (I have control) in the house? Listed in order of sonic priority: LXmini, OB-subs, signal is digital (no analog) all the way to the amps within the subs (no analog signals - not even XLR), only one (1) single conversion (which is digital to analog) inside the Hypex plate amps - no multiple conversions back and forth (ADC/DAC), reclocking or resampling/upsampling (like many systems). 

@mwatsme You measurement looks very good , you made good job . Only one question , What is distance between microphone and bass driver cone ?

If you an engineer , you must be know the lenght of low frequency wave . So if you stand close to driver the bass may be ok. But if go 3-4 feet to side the wave from front cone and back wil be eluminate each other , I am not hate anything. Each design have some issues , To be find out which is better in you particular room there is best way to make A-B comparision ,

@bache Every speaker design has “issues.”

You doubt OB’s, as if you’ve heard every OB. And yet here you are representing yourself as knowledgeable. Perhaps you’re filled with as many assumptions as knowledge? Personally, one thing I believe people can’t relate to is their speed. I couldn’t, until I heard them.

Now you’ll argue time alignment or whatever measurement, as if that relates to all OB’s. Personally, I think you protest too much. Argue away. I’m done listening to your opinions.
