What is the most dramatic way of increasing a speaker's Bass and Low mid?


Hi-

I am wondering what would give the most dramatic increase in bass and low mid projection/Volume, even on account of accuracy ...


My speakers can go down to 28hz but i need to boost it’s level, not frequency extension. They are 2 way with bass reflex port. 6.5" woofer size and a tweeter. Floor standing.

My floor is old hardwood strips.

placement and coupling methods are the first things that come to mind. I do not want to add an equalizer at this point.

Spikes, footers, concrete platform, direct floor flush contact? anything and everything that YOU know works.
Speculations on untested methods are not needed as i need real life experience from people.

Thanks!

Get four subs and use Room EQ Wizard (free) but extremely powerful, put those measurements into Multi-Sub Optimizer (free) amazing you can see the graph improving as the program creates filters, which crunches the numbers and builds the filters I put into a Mini DSP. You can do up to 12 couplex biquad filters. . . It’s amazing the impact, accuracy, and power that the subs have when they work together. 

Without a doubt, the very best way to get high quality bass from your speakers is to replace the electrolytic capacitors in the crossover of your woofer driver with teflon caps.

You simply replace them using the same value and voltage rating (higher voltage is OK, but not lower). Since you won't have enough room in your speaker cabinet, that will be a problem you'll have to solve.

Being an audiophile ain't easy.
@orpheus10 I just curios How you know  this particular speakers
using electrolytic capacitors ? did you see schematic  ?
