Adjustable Spring Bass Traps

If a standard basket / cone speaker can produce a certain frequency, can the same design collect a certain frequency?

I want to design an "Adjustable Spring Bass Trap", with passive radiators as the collectors..  I need to do some tinkering.

We use to call something that took vibration and surge out of hydraulics an accumulator or better known as a shock absorber.

I have a pair of 12 cubic foot columns 1.5" thick 60 x 22 x 18".

I have 8 12s, 4 15s and 4 18" high excursion radiators. I think 1 12, 1 15" and 1 18" will do the job.

I think if they were concave with no dust cap or inverted dust caps that would improve collection.

Do I port the the passive radiator? Seems weird to port a port, or will the box just collect bad BASS so to speak?

Do I hang dingle berries inside to dampen the "BAD BASS"? I'm thinkin', I think.. Could just be my OCD kickin'

1/2" rubber rope inside going through eyelets, 20 or 30 will do. Terminate the rubber rope with hog rings or zip ties.
Can I adjust the rubber rope to collect "Bad Bass" too?

An IB design, a ported design, and active design, that uses an active speaker to react to "BAD BASS"?

Me the dog and the rabbit (Junior) got an idea, I haven't let the chickens in on yet.. 

What do you think?

Not to compress ausaudio As a muffler.. as a filter.. You ever see a water muffler?

What about WET stacks on marine diesels? You'll have to trust me on this one.. A pair of V12 Cats in a tug, can get LOUD (130+ db) yet quiet as a mouse with water muffs..130+ db easy uncorked.

I use to work on Hydro-blasters.. 15,000 psi HP water jets. Water does not compress.. LOL BUT is sure quiets things down, and it transfers SOUND pretty dog on well, too. 

Those noisy POS used 6V53 Detroit (2 cycle diesels) with "WATER" mufflers installed into 3000 gallon scrubbers. Noise and Opacity test requirement, because of the location. You had to keep a 25 foot distance between you and the scrubber, too. The harmonics would crumble your bones..

Hydro water plants are the same way.. 15-30 minutes exposure, your DONE. Turbine growl is a bone grinder.

It's easy to fix stuff (Gas Monkey Garage). UNDERSTANDING what it does and is doing is another thing..

I need BASS mufflers, yup Dual INTAKE mufflers :-)

Old Heavy Master Mechanic, that gladly retired..

Put together a large array of noise canceling headphones modified with an adjustable low pass filter.

<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>

600 pairs of head phones. I'll head to the bank for a loan. What should I say I need the money for? I need 100K for my ??K system to add headphones.. "LOAN DENIED" LOL Big ol' red letters..

Start looking like Master Ms digs, with his "enbeddings", love that guys way of tinkering.. :-)

A:  Wouldn’t it be easier to adapt a swarm subwoofer setup as others have done to even out the peaks and valleys?  Perhaps utilizing in-wall subs if floor space is tight.

B:  IME, a crappy sounding room will never be a great sounding room no matter how many bandaids you throw at it.  Can a crappy room be improved?  Yes, but it will never be a great sounding room.
