Resistor Sourcing

Attempted to match resistance in each part of the Sub-Bass Filter perfectly:
- Number of resistors in filter: 9
- Number of resistors needed for perfect value matching: 15
Difficult to use exact resistance values because:
- Exact resistor value doesn't exist, needs to be realized by a series and/or parallel combination of resistors
- Resistor value too expensive:
  - costs more than $0.20 for one resistor
  - requires a minimum order of say 200 units
More resistors -> Larger PCB -> more expensive product
Ultimately, this is a personal project, a prototype, want to keep the cost down as much as possible, this is NOT a scientific measuring device, output of filters need just need to be within a certain threshold, care more about the dB visualization
(Obviously) percentage difference between ideal and implemented resistor values matters more than absolute difference
Differential between ideal and implemented values seems to balance itself out once all resistors have been selected
Finished sourcing resistors for all filters
