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!

It could be your room, you know. Read F. Alton Everest texts to learn about room modes. If you have a square or other poorly proportioned space no amount of gear at any price will solve this. As suggested by others, change your listening position. Mr. Everest will help with that and you may need to move more air with a sub. 
I haven’t read though the entire thread but, try high quality room treatments. I highly recommend the Stillpoints Aperatures.

Still, in this day and age, most people would rather trade a component for another at a loss/on top of a big extra expense instead of taking the time to try room treatments. Some have mentioned trying a Lyngdorf. My feeling is to get as far as you can go passively.This is the best path.
I am having the same problem with my b&w 800d. Suspended wood floor with 13/32" subfloor of particalboard. Crappy. Need to decouple speaker from floor. Spikes will couple the speaker to the floor. Isoacoustics have  newer product - footer that  will help decouple. Like the nordost sort fut  or some stillpoints options. Also townsend seismic platform.
Hello,
          Your request is not possible with the speaker you have, period. I have PMC speakers which are transmission line design and have great bass at lower levels but to get an increase at 28hz is unrealistic. I use a PMC twenty5.sub for foundation level bass below 60 hz. It blends in perfectly. Don't waist your good money on tweaks. 
Happy listening.

My experience with 2 way speakers ( rear ported )  showed me that 
moving the speakers closer to the walls create bass bloat ,
so stay at least 2 feet from the front wall .
Spikes are good as others  have suggested , but the thing that
made the bass stand out the most was corner room treatment ,
for my room it was the corners behind the speakers that cleaned up ,
cleared up and tightened up bass response .
Cables do make a difference , try to find 10 gauge or larger .

Good Luck
