Secondhand Powered Speaker

Second hand powered Speaker. Please see pictures for model and model number. It's quite old. But I cannot use it now for my current sound needs. I have a powered mixer so I need to passive speakers. Also the sound does not meet my standard of sound for the purpose of which I need it for. I do Gospel events and sometimes even outdoor ministry. I am selling as is. No returns and no warrantees. I do not know much about inside of speakers. But I know sound. And it sounds like something is missing.. it's isn't bass. So it might be some sort of tweeter. But it does give bass and mids sound.
