Thanks for the responses! So these would probably sound better indoors??
depends on the level of boom. If you're problem is always reverberant sub-bass/boom in a specific room/location, then it would help, but so would doing a HPF later, if it's mid-upper bass, then I think you'd do better to just learn how to EQ the problem frequencys.
To actually answer your question, between indoors and outdoors, these would sound better indoors.
