When I was in the Marines in 84' stationed in Okinawa everyone was putting together really nice stereo systems you could buy at the PX or in town really cheap compared to the States. Bose was it for speakers and the 901's were the sh*t but hard to afford on a serviceman’s salary. Bose had some kind of an agreement with the Government and they pretty much had a monopoly on speakers.
Anyway we had just come back from a deployment in winter time Korea and were having a big bash in the barracks that involved a lot of drinking. Music for this gathering was being provided by a proud owner of a pair of Bose 501's and they were doing a decent job, especially considering the amount of alcohol we had consumed. Someone had consumed a little too much and mistook the BOSE 501's for the toilet and peed all over them, soaking those fine paper drivers.

The next day we put the 501's out in the sun to dry out and when they were dry the 501's not only worked just fine, I SWEAR they sounded better!
So the hell with getting two EQ's for the 901's; just pee on the drivers and I swear as soon as they dry out you too will be experiencing the coveted chocolaty midranges!
