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!
Rea

You need good bass  and midbass response just from one 6.5 " driver??
You have to look bigger size at least 10" or two 8" at least .

you say that you speakers with 6.5" driver go down to 28Hz.
i just curious how you know his?  Did you take measurement ?
for my experiences only big boxes with drivers 12-15" can achieve
this down point with -3db.

 You can try use different cable ,  move you speakers back ,  but you 
never get not only dramatic changes , may be very very small changes.
you can listen my advise or not , but as speaker designer i suggest you 
first-most easy way , use  equalizer to boost 100-400 Hz, second more
kosher way, use you sub and change crossover in you loudspeakers
 apply baffle step crossover and high pass crossover for you 6.5 woofer.

Loudspeakers with 500 -700 Crossover frequency between woofer and midrange  
@orpheus10 I just curios How you know  this particular speakers
using electrolytic capacitors ? did you see schematic  ?
I think you wrong , woofer crossover 1st order use just the coil, no any capacitor, Crossover 2nd order, use capacitors , but 99.99% using teflon
capacitors. the teflons capacitors get different grade and low grade cost
50-100 mkf cost $5-10 , electrolitic cost around $1.  I did not  see electrolits
in mass bestbuy speakers. 
My friend tell---- if so , why he install electrolytic capacitors  in crossovers and
let you change capacitors for teflon. i dont want to explain my degree, i  also design and selling  speakers. i just told you about you  wrong post----only 
very expensive  loudspeakers using teflon capacitors +
orpheus,  sorry ,crossover is yours, enjoy , but i dont  understand, is not clear what type capacitor you  install teflon or polypropylene? you first recommendation
that ------ 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.----- Sorry Greg Bache
@Fraterperdurabo   you right for 100%  The majority interesting ideas
is placebo effect. Get measuring tools  is very helpful. 
I am  electronics engineer with big experience   to speakers building
and have currently selling speakers.   i say--  you have to use  the both--
you ears  because the ears is very precise and measuring tools.
measuring microphone also very important, see all stereophile  
revue , they make measuring test for all famous brand,  i dont think
you can recommend John dont do it
