last week i was wondering why my great plains 802 drivers with Tangerine phase plugs sounded harsh in the high frequency's compared to my old annular slit phase plug 802's everything is the same horns amp's so why do i remember the older drivers sounding better? Then it hit me no their is one difference adapters i use a 4" long adapter that couples my 1" drivers to my 1.4" Elliptical Tractrix horns my old drivers bolted straight to the horns no adapter the reason i started using the adapter was to get the face of the horn to the edge of the cabinet face the drivers are spaced the same distance as a model 19 cause i run the same components and a version of the mod 19 crossover so they served only cosmetic purposes. Well when i hooked the great plains 802 straight to the horn put on some vinyl and sat back in total amazement i never would have thought a 4" long adapter would have made such a difference HUGE difference now i am in love with my Tangerine phase plug 802's not only was the adapters making the highs harsh it was also effecting the midrange now everything sounds perfect listened to my vinyl till 4am just got up and started listening again these things sound Amazing. So dose anyone have a theory on why the adapters ruined the sound of my 802 driver?
