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!

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

Make sure your amp’s input impedance is compatible with your preamp’s output impedance. I believe the rule of thumb is there should be at least a 10X difference between them.

I have a system with book shelf monitors and I cannot believe how much difference filling the stands with sand/kitty litter has made! It solidified the entire soundstage, and extended the bass. I highly recommend that anyone using stands performs this, you’ll be amazed the improvement it makes!

My floor standing speakers are also filled with sand, but that’s the way they came I didn’t experience the transformation as with the stands.

There are tons of interesting ideas on this thread.

But I'm going to reiterate: you can't fix what you can't measure.

Get a USB measurement mic from Parts Express.  Use it, and post a FR plot.

Let's see exactly what we're dealing with.  Then you'll also see what your improvements do.  It's possible that relatively minor adjustments in speaker placement could yield the improvements you're looking for.

Ears are great and all, but the placebo effect is all too real - I worked in Pharma QA, and it is frankly terrifying.  It is only now, more than 20 years later, that studies suggest Prozac MIGHT work better than a placebo, for example.  The analogy to various audio tweaks is left as an exercise..
@Fraterperdurabo   you right for 100%  The majority interesting ideas
is placebo effect. Get measuring tools  is very helpful. 

I'm an electronics technician who is very accustomed to working with all kinds of measuring tools, but the only thing that can measure "high end" audio is a pair of keen ears.

The people who don't have them wouldn't understand that fact.
