ok so i have two oz audio ME 10.4's one of which just got its dustcap ruptured during a move. it's a nice sized crack that spans the diameter of the cap, but it's not a hole. i've tried numerous times to contact oz to get a replacement to no avail [and i've heard they don't offer replacements after the warranty period anyways] so i did two things.
first i epoxied the crack yesterday. second i found someone with an ubranded RE SR dustcap that seems to be the same shape sans oz audio imprint.
pic of RE SR for reference:
so my question is whether either of these modifications to one sub will alter the combined sound of both subs. i know you're not supposed to mix speakers that produce differing representations of a certain frequency range, but i'm just not sure the extent of the effect something like this will have on freq response.
with the epoxy there is a little bit of added mass, though it may not seem like much i'm sure it's pretty heavy relative to the weight of the cone. with the RE SR cap there is probably some lost mass. in addition to this i guess the fact that the imprint is either added to or detracted from so i don't know if that shape difference will cause an audible difference in sound.
any advice would be great. thanks fellas.
