Thanks, Paul
I have seen your comment about the TAD bug screens at AA. The bug screens are a touchy subject – with some driver removing them works fine with some made sound worse. I did not experiment with TAD’s bug screens…
Generally the bug screens do slightly more than preventing the cockroaches to crawl down into the gap and to build a colony in the driver. The bug screens acts s very effective diffuser. Also, and probably the most important, the bug screens has own acoustic impedance and create a very mild additional contra-pressure from the trout. Some drivers with reliving from this contra-pressure behave better and some worse.
There is another interesting aspect of it – the compression drivers do suck dirt from air and I usually once in a whale clean them. It is good idea perhaps to use very fine nylon stockings atop or instead the bug screens. I use black nylon condom around my Water Drop tweeter - the nylon is perfectly transparent but has much higher dirt catching capacity then any mesh metal screen.
