Yamaha MSP7 lowend sine wave weird test results

I did this test on my listening monitors Yamaha MSP7's

The Ultimate Bass Test | Ultra Low Frequency Range Test

It is a bit weird because I start hearing a hum at 30HZ and it gets louder at 40HZ and 50HZ but then at 60 -70 HZ it dips softer a bit and then starts to pick up closer to 100HZ. Is this normal? Could somebody else out there also please do this test and see what you get? How should these results be interpreted? Oh perhaps should mention that my room is fairly well treated in all the main reflection points.

What kind of treatment do you have? It's most likely an issue with the room. A dip in that area is common in home studios.

I used treatments as per the video since my listening space is the same size as the room used in this video (16ft by 11ft). I used 4 inch panels instead of two inch panels for increased absorption of low end in all my treatments on all early reflection points.

I don't think it has to do with my room. and what you are saying about home studios also is new to me. In all the books I have read none have said that the problem frequency would be 60-70hz while the frequency below that would be normal. Could you point me to your source of info please? What other tests could I do?

Without sub?

This test is not good. When the man said "30" i see 36-37Hz in analyzer from Adobe Audition.

I think a sub with the MSP7s would just give you a false sense of bass.

Just keep in mind what 90%+ of people are using to play music on these days.

As mentioned in the Other MSP7 thread you started recently, you gotta learn to read them and adjust your mixes accordingly.

You don't have to buy a $10K system to hear how your work sounds on a $10K
system.

Go to a better audiophile store, but also check your mixes on everything from car stereos, headphones, TV speakers, computer speakers to get the best overall mix.
