Welcome to Speakerplans Samuel
The first thing you should do is measure your sound card. Your sound card will be giving you answers many will not be able to answer as time progress. Measuring your sound card is merely, looping the outputs into the inputs and, performing a sine wave sweep. By doing this, you will have a reference point (Your audio interface Frequency Bandwidth).
You can download Room EQ Wizard as, it will give you everything you need to make measurements.
Once you have measured your sound card, you will remeasure it again, however this time, you will insert the audio processor you plan on using in one channel of the chain between the input/output of the sound card. The other channel will follow the previous method of being looped directly from the input to output. This will allow you to see if the processor altered the signal or not.
Since you are measuring the bass response of the processor, you can begin from 100 Hz – 1 Hz or vicar-versa.
Amplifiers will require to be benched test (Oscilloscope & Dummy Resistive Load). An Amplifier may cut back it's power or, ramp into DC Protection, once driven rigorously, under the given load, below 20 Hertz. Most of the guys that bench test amplifiers below 20 Hz can be found on AVSForums due to being heavily Home Theatre influenced.
Personally, the only amplifiers that I have benched that can I guarantee will meet or exceed their specs in single digits are the old iron-core Crown Amplifiers. This is why, I've used them for over 30 years. I would have to check my notes but, I recall them still meeting their advertised specifications down to 5 Hz.
However, you should visit AVSForums for there are many who have gotten great results benching more up-to-date amplifiers. You will also get real-world feedback of users focusing on the field you are planning to partake.

If you are looking to build amplifiers for yourself, a wealth of knowledge lies in DiyAudio's Solid State section.

You are going to find yourself fairly limited on many audio sites for, the majority are not interested in reproducing 10 Hz and, will try to steer you away from such a notion based on what they feel is right. It is a common trait of thinking outside the box so, I am giving you fair warning in advance.
Best Regards,
