Hello everybody!I was offered two of these speakers for reasonable price. I think. Maybe. They are P.A. subwoofers, and I think i could use them crossovered at 650 Hz to JBL 2360. What bass extension could be produced from these speaker in hi fi use without EQ? They are specified at 40 - 1100 Hz at -10 dB. Is that - 10 dB at 1100 Hz or at 40 Hz?
