Re: New DIY Mid High
Its "Paul’s 90 degree DIY from England mentioned in post #385, taken in an anechoic chamber at Birmingham University" as Art said.
Here's a picture of my latest (prototype) box - its heavier, bigger, doesn't go as loud, but it goes lower and the sound quantity and directivity are improved. FWIW it uses a BMS HF driver and some new B&C speakers.
Its the best sounding PA box I have ever heard, incredible stereo imagine and depth of field, you feel like you are in the studio. You hear things that you have never heard in the recording before, but unfortunately the horn flare is not generally available. I am however planning to do a new version of my double 10" based on the tricks I discovered with this design.
.... and I have taken a big jump and started work on a small 8" Line-array !!!
