Well, I don't know much about waveguides only started my research on them a little while back. I am considering seeing if the exponential waveguide part of the kit can be enlargened(I won't be purchasing the waveguide I will be DIY'ing it with CNC) somehow to give a wider response vertically. Obviously ill talk to Visaton get an idea of what they think is possible or other options available. To be honest first things first, understanding beam angle technical specification given with waveguide by Visaton.
You should be able to do this with any loudspeaker design that you like. While you can use the existing XO points from the passive XO as a starting point, you will be in a better position when measuring with Audiolense as you will get to see the passband of each driver and zero in on the ideal XO point.
I have some basic experience measuring my subs with Audiolense attempting to compare transients with impulse response and trying to figure out the highest frequency it will play according to the measurements. So yes, I will measure and then understand how the each driver with its particular cabinet interacts with the room acoustics and see if the XO's need tweaking.
However, on close inspection, while the woofer could make it up to 1 kHz on and off axis, the combo CD and waveguide combo had a glitch at 800 Hz. I have attached the plot to show the before and after driver linearization to show that the glitch is still there.
Great I will look into this great example thanks.
The Audiolense digital XO's are linear phase so that they sum perfectly in amplitude and phase. Further, the driver's passband acoustic slopes are "convolved" into digital XO crossover slopes, so this is how they still sum perfectly from an acoustic perspective as well. You can't go wrong 
Actually, I was thinking of writing back and asking the "complexed" question of "will I be able to get good results not using the original crossover"? and the above seems to answer my question. I suppose if we are digital crossover guys(I will get there soon) we should just drop all preconceptions of digital crossovers and put the hard yards in.
Most of the 15" that I use are "short stroke" stiff cones in (very) large boxes. I have found this is what gives the "kick" or "chest punch" sound. TI have found "long stroke" woofers can get the kick sound to, like Purifi's new PTT6.5 (sub)woofer can do, albeit at a lower SPL than the large cones.
This at least points me in the right direction, obviously reading your previous post I knew that short stroke must of had something to with the kick if you mentioned it as a variable. Now, I can at least do some research without the preliminary starting point that us amateurs are usually stuck in for a while till asking the right questions. I will use DIYAudio and see if that helps...
I do have a second option with a 15 inch speaker called Calpamos from Humblehomemade HiFi its not PA but its sensitivity is high, who have given a great explanation in a PDF on their choice on the 15 inch Faital Pro 15PR400. Its combined with a typical 2 inch compression driver and waveguide, this seems like a great option have no qualm about it. But the Visaton for one, is a 3 way and the Faital Pro drivers are expensive with only parts express having it for cheap but don't know for how long. Point being, either I am going to go ultra high end with a few bob more, or I will go with the Calpamos when I can find the drivers on special.
Let us know what you find out.
Happy Holidays!
