  1. extending cabinet range with tube
    I have the JBL MR 812. It is a 300 watt 12" Speaker in a small box. the port hole is kind of small. Is it possble to get the speaker to respond to the 41 htz of the low E? If you add a tube extention to the port?????? Now, there is just a hole. Now is sounds good down to the lowA. On some speakers the port hole has a tube running into the speaker???
    Any ideas for a confused bassist/
