Does anyone have experience modifying the x-over filter in QLN Reference HD2. I would like to tighten up the base and and make the overall sound more open and less boomy.


Don't know anything about the XO, but there are many things worth tweaking before you even look at the XO.

Are they ported speakers? Try some stuffing in the port.

More later.
