I have a used 10" speaker from a JVC powered subwoofer for sale. This is an 8-ohm speaker that I measured at 6 ohms DC resistance. It has a heavy magnet and coil -- it weighs 8 pounds. I'll include the JVC subwoofer enclosure if you want it.
I usually don't reply to lowballers -- I'm not being rude, just saving both of us some time.
My name is Roy and I'm located west of 80th & Wadsworth in Arvada.
I'm very good about removing my listing once an item has sold so, if you're reading this, chances are very good that this speaker is still available.
