Anybody ever tried a beam blocker in a coaxial cab ?
What did you try and how did it sound?

Otherwise known as (Jay) "Mitchell donut".I would use "aperture shading" before I used a beam blocker. A simple method is to use a piece of rigid foam and cut a hole in the middle about 3-4" in diameter. IIRC (from my sonar days) polyurethane or polyethylene foam is a good choice.
Aperture shading can be used with a coaxial speaker and will reduce the directivity of the low-frequency driver.
Not pointless. The low frequency driver will be quite directional up to the crossover frequency. This is why the CLR uses a donut.Otherwise known as (Jay) "Mitchell donut".

But as @Tigerfish pointed out, using it with a coaxial driver is pointless
That's right. So we can say it depends on the crossover frequency, if it's around 1200hz or lower the donut is pretty much uselessNot pointless. The low frequency driver will be quite directional up to the crossover frequency. This is why the CLR uses a donut.
What ya want for ‘em?I bought a pair of beam blockers a few years back, and installed them in a pair of FRFR speakers I had which were too directional. They really worked well. I no longer have those FRFRs so, if anyone's interested, my beam blockers are available
