I'm curious about what Maelstorm is saying. Is that true about the 6x9s? What about 6.5s? Mine are all Infinity, if that matters. What does freeair mean, and why would a small enclosure be bad for it? My 6.5s in the front are enclosed in foam baffles, but I think because I made cuts on them to pull the wires through, they create some distortion. Any tips?
