I have a pair of Scumback J75's for sale. 16 ohm, 30 watt, 75hz speakers with a 40 ounce magnet. Scumback website describes them as a sound right in between the M & H speakers. These speakers are still basically like new with very low hours on them even though I've had them since 2012 when they were made. They had the FBI (broken in) treatment. There is light solder on the tabs, but they cleaned up pretty well. I have speaker boxes for them and they will be packaged extremely well.
