I'm with Onhwy61....you probably have typical room bass boost. You need to tone down those bass bumps rather than boost 80 to 300 Hz.
Secondly, above 200 Hz...you are dealing with wavelengths of roughly 5 feet...don't expect any kind of smooth response here as movements of a couple of feet of the SPL meter will give you nulls when playing pure test frequencies. (for example quarter wavelength cancellations off the back wall behind the speakers is typically evident with a series of nulls from 40 up to 500 Hz depending on speaker placement)
See this link Quarter Wave Cancellations Explained
The above is why I have soffit mounted my speakers into a heavy braced wall cabinet. This is most important for larger three way full range speakers and is why you see soffit mounting of studio main speakers in almost all studios. (The difference is very audible as you can imagine by looking at the frequency response curves shown in the URL example I gave you above)
Finally, I suspect a 1 Hz pure single frequency test tone with an SPL meter is likely to lead to frustration unless you are an expert like Rives and know how to interprete it.
For example, imagine (in theory) that your speakers are perfect ( zero distortion ) then you will get enormous peaks and nulls with single pure frequency test tones (as the ONLY frequency in the room is exactly what you input to the speaker).
Alternatively, imagine your speakers are more normal or typical (with 50 % distortion in bass frequencies when played at louder SPL levels ) then you will get a beautifully smooth balanced SPL response when playing pure single frequency test tones (because not all the harmonic distortion will be affected by the room in the same way as the fundamental - and SPL meter will pick up the average)
How's that for counter-intuitive.....two different speakers placed in the same position in the same room and the better speaker SHOULD measure far far worse!
How's that for counter intuitive....an amplifier with higher amounts of harmonc distortion may actually sound more balanced compared to a perfect amplifier with zero distortion, as it is less ruthless on room modes.
All this is because nulls will be their very worst when you have pure single frequencies....
So be very careful interpreting 1 Hz pure frequency test tones! (It is unlikely that kind of purity is actually coming out of your speakers unless they are incredibly good and you have an amplifier with very low harmonic distortion)
