you have to pull the woofer to get to the crossover don't you ????
No. Bear in mind that this is a pic of a H2 to H3 conversion, but I think the H3's are built the same (not positive though). Pulling the woofer would give you more of a line of site in the cabinet, but might leave screwdriver marks on the woofer screws and the chance of puncturing a surround. I'd rather go through the back if possible, for cosmetic reasons if nothing else.
