What is signified by the B and R markings next to the phone jack inputs to the LF crossover?
One of the catalogs shows a cross-section cutaway of the crossover. I don't think that I'll like working in that space. What are the chances that the L-pads or pots are in usable condition? They do seem to crank smoothly.
The drivers are LE15A (for sure), and probably 2105 and 077.
So, what are good port dimensions for an LE15A in a 5 cu ft enclosure? If I port it, I should pull out all the stuffing and cover 3 of the walls with some kind of other deadening material, right?
When I look at the price lists, I see that LE15A was the most expensive woofer, so I'll guess that there is not much reason to look to replace it.
Thanks
