You do realize that the room plays a great deal in terms of response.
As to "2 gaps in frequency sweep" please describe in detail what you're referring to, and how you derived that conclusion. Feel free to use terms such as boomy, thin, tinny and avoid actual technical data. Be sure to assume that all rooms are furnished the same, walls and floors are always the same density and of the same construction, speakers placed in the same relative positions and generally ignore any room fundamental nodes or areas of comb filtering effects.
No, really all sarcasm aside. describe what you're hearing.
After doing polarity and phase tests, aligning the drivers towards the average ear heights, I 've never bothered with a single tone frequency sweep as it's absolutely of MINIMAL concern with voicing a system. In fact, using a real time analyzer only sees 2 dimensions of what is a 3 dimensional activity. As such, it's data is of limited use.
I watch the SPL meter and look for room nodes, sure, but GENERALLY SPEAKING , most consumers DON"T CARE. If the sofa jiggles a little when the T-Rex is jogging in JURASSIC PARK, or when the shells are landing in Apocalypse Now, it's all good. No one has ever said , "there did you hear that -2 db to - 4db variance between 250 and 700 cycles !?!??" or "Make sure 40 to 160 cycles is'nt overmodulating at the input of the amp, it's sure to thermal if you don't"......
Dude, if you care, you'll take note of things most people (who don't care ) wouldn't otherwise notice.
