I have for sale a pair of JBL model 4311B professional studio monitor speakers. These are NOT home hi-fi speakers, but are vintage professional studio monitors.(Although they can be used in a home hi-fi application.) These are for use in a recording studio control room, or for audio monitoring in a video production suite.They would also be ideal as the main speakers in a small theater. The cabinets show their age, and have some very heavy duty mounting hardware attached.They also have a few tiny screw holes where some additional mounting brackets were removed.One grill has a stain. I am asking $350.00 for the pair.Payment is cash, or a check from a legitimate non profit organization. Please e-mail if you are interested, and I will e-mail you pictures and additional info about these professional studio speakers. Thank you.Roy StueweWestlake Ohio
