Has anyone heard a Murphy Corner Line Array? Does anyone here own one?
If so, what are your thoughts and impressions?

The thread got long and convoluted so reading it all has become difficult. If there's something specific you would like to know I'll do my best to help.Thanks.
I read some of your thread over at diyaudio.
This Jim Griffin paper holds up pretty well for required line length vs. frequency:Personally I think the 70% rule is fake. Test: at what frequency?
I didn’t want to mention shading because it only makes a difficult enough project multiple times more difficult, and doing frequency shading without delay shading is pretty half baked.
I agree that the EQ requirements can be managed: all of the issues can be managed, such as your attempts to manage truncation with a near – enough rule, and beaming with ‘not that bad’.
But for me, it all added up to too many compromises heaped upon other compromises, to push ahead with a speaker that, in his original attraction, was all about idealistic appeal.
There is no fake news here, I and others have simulated, built and measured full range line arrays. All are in agreement. There are papers from Roger Russell, David Smith and Jim Griffin that provide the same information.Personally I think the 70% rule is fake. Test: at what frequency?
Has anyone built this as a two way? would seem to address a lot of the issues. The bass drivers could be larger and improve LF performance, no doppler, beaming ETC. If brickwall FIR filters are used then issues around the crossover can be kept out of the ears critical bandwidth.
This might be a dummy question but what about sound stage depth when using these line arrays in the front corners?
Will there be any depth at all? I am asking as based on my experience the further away the speakers are from the front wall the deeper the stage will be and these speakers are anything but away from the wall
Thank you
Quite right, but as Roger Russell would have said, paraphrased, “nothing to see here, I see line source speakers that break all the rules and sound juuuuust fannnnnntastic.” Which takes me right back to the first line of my first comment: we get ‘mind blown’ subjective reviews for every type of loudspeaker.I realize that there are issues with the driver Murphy used and high frequencies.
