Yes i agree. Im a noob and admit it haha
Only way to stop that ringing is thick bass traps correct? (Which wont happen in my current room)
They'd have to be too thick to be practical. 1/4 wavelength thickness is needed. The wavelength of 30Hz is 38 feet, so the traps would need to be 9 feet thick! Optimising sub and speaker placement is the way to ameliorate this ringing. And using multiple subs.
Just to clarify something, there has been a lot of research done and while the common/text book thinking is that 1/4 wavelength treatment is needed for 100% absorption it is absolutely not necessary for such thick/large treatment to have very good/adequate absorption.
Over on Gearslutz which is where I spend most of my time and truthfully where I've learned a whole lot about acoustics it has been proven and is pretty much common knowledge that 1/7th is absolutely enough for great absorption.
Remember, once you get past about 8" of thickness it is much more effective (and much cheaper, too) to use pink fluffy insulation instead of the more dense stuff like 703/mineral wool/etc.
I HIGHLY recommend playing around with the great, accurate, and easy to use modeling program at http://www.stanleyhallstudios.co.uk/pacalc/ where you can see the differences that different thicknesses, with and without airspace, and different densities makes.
Remember, pink fluffy is about 5000 rayl/s, Safe N Sound is about 12500 rayl/s, OC703 is reported as several different rayl/s unfortunately, but I stick with about 22000 as it most closely resembles my own tests after modeling, and oc705 (wouldn't use this for more than about 4" thick - if you model it you'll see why) again is reported as several different rayl/s but in my very limited testing with this particular product, the models most closely align with reality in my room when I input 35000 rayl/s for oc705.
So in this post you have the link and all the data you'll need to input for the different types of treatment you'll come across.
There is no reason to not model different types, layers, try different densities/types (one in front of the other and vice versa), airspace, no airspace, etc and come up with a great combination.
This will also let you see how low your trap will be effective and if you don't have enough room to make it big enough to be effective low enough and if this happens for a large percentage of people and there is interest, then we can start talking about more complicated designs that don't take up nearly as much room but are harder to make or more expensive to buy.
Hope this helps,
PS Since this is a long post as most of mine are, the main point is that there is a common misconception that absorbers have to be 1/4 wavelength to be effective and this just isn't true. 1/7 wavelength will get you an extremely effective absorber.
