i got a set of 70s speakers. can't remember the make. i looked them up at the time i got them and they retailed for 1600 for the set when they were new. together they weighed close to 150 pounds so there would have been no way to pick them up on a bike without a huge trailer. easily the best sound i have ever heard and at 100 watts i can pump the volume high enough to unshelve books.
