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?

oldhvymec, can you catch an explosion in a tin can? I think you'd better think up a more viable project. Let's see...making subwoofers is fun. How's about designing a room that has no bass nodes. Maybe you could turn your roof into a passive radiator, put it on springs. Watching it bounce would be cool.

Maybe springs on the French doors will work as a poor mans substitute. Besides they are already there..:-)

I'm not trying to "catch it all", BUT I would like to make a dent in the frequencies I'm trying to work with. 45-55, 75-85, 115-125, 250 (?)
pretty normal bumps and valleys. The 250 up is pretty easy. Wall panels but below 125 hz... and a fairly easy to make trap? Not to darn ugly.. Just ugly enough..

A guy was making exactly what I wanted BUT he quit making the ONE trap I really liked.. Naturally!! I think the proper term is SOL.. LOL

With me any more 15 min 3 times a day.. My hand quit.. Twist up like pretzels (sp), silly things.. I can get a lot done in 45 min. though..

I wonder if a sail mounted to a box, or a collection horn into a dampened box? Or into water? LOL turn sound into bubbles? Why not..

Regards

Just wondering Oz your plans for, well assuming you are able to trap some bass, then what? Trophy size I suppose taxidermy, small fry get the skillet?
