This is the same driver in my current A7s and I couldn't agree with you more. My 902 8b also had loading caps on the back of the diapram, which is the good one, not the symbiotic which I also have. Whip off the back covers and see what you see. If it is a shiney aluminum dome and there is felt in the back of the covers, then put them back together. More than likely, unless already removed, you will not see the shiney dome, but a dull plastic dome looking thing. that is the loading cap. Also, there will probably not be felt in the back of the cap. Call bill at great Plaines Audio and purchase (VERY inexpensive) two felts and six short screws, (3 to each driver) which will replace the existing three screws which will be too long with the loading cap removed. Install the felts and reassemble. Much nicer on the high end, and a little more extension and air. Easily reversible, but you won't want to. this basicall converts the 902 8B to a 902 8A. There can be other slight differences on some models, but soundwise you,ll never tell. Sorry if you already knew all this. Apparently these loading caps closley hugged the back of the aluminum dome, creating a cushion of air to help control the diapram at crazy high (not home) volume levels. However, it shaves of a little of the high frequency transients. Enjoy.

Great drivers,
Russellc
